Assessing The Knowledge, Attitude and Practices of Malaria Prevention and Treatment in Mansa District, Luapula Province, Zambia

Introduction: Malaria continues to be a major public health problem in Zambia with more than 16 million people at risk and 2015 estimates show that there were over 5 million malaria cases. Children under five years and pregnant women are at the greatest risk. Despite Zambia’s interventions including universal insecticide-treated bed-net (ITN) coverage and indoor residual spraying (IRS) in targeted areas strides in the fight against malaria, the situation in Luapula Province is totally different with the highest incidence in pregnancy, 131/1000 in 2013, 207/1000 in 2014, and 177/1000 in 2015. This research therefore assessed the knowledge, attitudes, and practices of malaria prevention and treatment in Mansa, Luapula province of Zambia. Material and Methods: A descriptive cross-sectional study design adopting both qualitative and quantitative study approaches was used on 270 study participants who included community members, pregnant women and health personnel in Mansa ward of Mansa district. The participants were sampled using simple random and purposive sampling techniques. Data was collected using questionnaires, interview guides, and focus group discussions. The quantitative data was analyzed using SPSS statistical software, while the qualitative was thematically analyzed. Results: Out of the 270 participants, knowledge of malaria transmission being due to mosquito vector was very high and seen in 270 (100%), however, other perceptions of transmission were; drinking contaminated water 3(1.1%), eating a lot of mangoes 7(2.6%) and coming in contact with a sick patient 207(76.7%). Participants negative attitudes stood at 196 (72.6%) and bad practices was 153(56.7%). Education level was strongly associated with knowledge (p=0.000), attitudes (p=0.001) and practices (p=0.004). Conclusion: Even though knowledge levels on malaria were high and comparable to other studies, however, some attitudes and practices were negative among the participants. On the contrary, healthcare providers had the right attitude towards malaria prevention and control. Community Health Workers are very important in the fight against malaria. The study recommends that creating health promotion messages taking into account the illiterates, involvement of traditional leaders, and giving incentives to community health workers can help in the fight against malaria in Luapula Province.

Malaria Outbreak Investigation in Nensebo District, West Arsi Zone, Southeast Ethiopia: A case-control study

Background: Malaria-related morbidity and mortality are 94% concentrated in Africa. Ethiopia is one of ten African countries affected by malaria, with 60% of the population living in malaria-risk areas. Recently, seasonal outbreaks have been reported in all regions, including previously malaria-free areas. Nationally, the Nensebo district of the west Arsi zone is classified as having very low transmission. During the 21st WHO week of 2021, Melka Denbi kebele reported an unusually high number of malaria cases to this district. The purpose of this study was to look into the magnitude of the malaria outbreak and the factors that contributed to it. Methods: A descriptive study was followed by an unmatched case-control study on 86 cases and 172 controls who were chosen at random. Malaria cases were those who were confirmed positive by rapid diagnostic test (RDT) and were line-listed at a health facility, while controls were those who lived nearby and were confirmed negative by RDT. At a p-value of 0.05 and a 95% confidence interval, logistic regression was used to identify malaria contracting factors.Results: With a mean age of 22 (12.31SD), the overall attack rate was 20.2/1000. Plasmodium vivax (PV) 105 (52.8%) was the most common. Staying out at night (AOR=3.94; 95%CI: 2.18-7.37) and stagnant water/intermittent river within 1 km of the vicinity were risk factors. Screened houses were protective (AOR=0.49; 95%CI: 0.27-0.89), as was knowledge of malaria transmission (AOR=0.51; 95%CI: 0.28-0.93) and prevention and control methods (AOR=0.50; 95%CI: 0.27-0.93).Conclusion: The illness was caused primarily by PV species known for their relapsing characteristics. Risk factors included stagnant water near homes and sleeping outside at night. Malaria screening centers and increased public awareness reduce the risk of contracting the disease. Our recommendations included regular environmental monitoring, behavioral change communication, ensuring radical cure, and further research with a detailed entomological survey and climate variables.

Gaps in knowledge and practices of malaria prevention in Francophone African immigrants in Metropolitan Edmonton

BackgroundImportant knowledge gaps exist in the understanding of the management of the risks of imported malaria in Canada among Francophone immigrants from sub-Saharan Africa (FISSA). The aim of this cross-sectional study was to investigate the malaria related-knowledge, attitude and practices (KAP) of FISSA in Edmonton, where these immigrants are in an official minority language situation and the impact of language barriers on these factors.MethodsA structured survey was used to examine the KAP of 382 FISSA in the Edmonton area from 2018 to 2019. Fisher’s Exact Test was applied to determine if there were associations between knowledge of malaria and different risk factors.ResultsAlmost all FISSA (97%) had an accurate knowledge of fever as the key symptom of malaria. Interestingly, 60% of participants identified bed nets as a preventive method and only 19% of participants had accurate knowledge of malaria transmission. An accurate knowledge of symptoms was significantly associated with a high perceived risk of contracting malaria [odds ratio (OR) 4.33, 95% confidence interval (CI) 1.07–20.62]. Furthermore, even though 70% of FISSA had a high perceived risk of contracting malaria in endemic regions, only 52% of travellers had a pre-travel medical encounter. Importantly, language was not the predominant reason for not seeking pre-travel medical advice, although 84% of respondents chose French as their official language of preference when seeking medical advice. Having a French-speaking physician was correlated with satisfactory prevention knowledge (OR 1.96, 95% CI 1.16–3.35). With respect to health-seeking behaviour, 88% of respondents with a child < 5 years of age would seek medical care for fever in the child after travel to sub-Saharan Africa (SSA).ConclusionThis study highlights that factors other than knowledge, risk assessment, and language might determine the lack of compliance with pre-travel medical encounters. It underscores the need for effective strategies to improve this adherence in minority settings.

Knowledge and practices surrounding malaria and LLIN use among Arab, Dazagada and Fulani pastoral nomads in Chad.

Chadian pastoral nomads are highly exposed to malaria due to their lifestyle and their mobility between various endemic areas. To inform strategies to reduce nomads' risk of malaria and associated morbidity and mortality, it is important to understand the factors associated to their knowledge of malaria transmission and prevention practices. A cross-sectional study among Arab, Dazagada and Fulani pastoral nomadic groups was conducted in February and October 2021. A validated structured electronic questionnaire was administered to assess knowledge of malaria. Attitudes and malaria prevention practices were assessed on the basis of perception of the causes of malaria and the use of a long-lasting insecticide-treated net (LLIN) the day before the survey. Data were analyzed using Chi-square tests and multivariate logistic regression with covariates adjustment. A total of 278 nomads aged 20 to 65 years were included in the study. Overall, 90.7% of participants surveyed had a good knowledge of malaria. Fulani respondents were more likely to have a good knowledge of malaria than Arab respondents (Adjusted Odd ratio (AOR): 5.00, 95% CI: 1.04-24.03) and households possessing a LLIN were more likely to have a good knowledge of malaria (AOR: 9.66, 95% CI: 1.24-75.36). Most nomad households surveyed reported sleeping under a mosquito net the night before the survey (87.1%) while 98.9% owned a LLIN. Daza respondents (AOR: 0.23, 95% CI: 0.09-0.56) were less likely to use LLINs than Arab respondents. The middle (AOR: 2.78, 95% CI: 1.17-6.62) and wealthier households (AOR: 6.68, 95% CI: 3.19-14.01) were more likely to use LLINs. Knowledge of malaria was associated with the use of LLIN (AOR: 12.77, 95% CI: 1.58-102.99). There remains a need to improve nomads' understanding of Plasmodium falciparum-carrying mosquitoes as the vector for malaria transmission and the quality of information provided. Knowledge of malaria and its prevention strategies in nomadic setting lead to the use of LLINs. Further reductions in malaria morbidity can be achieved by improving nomads' access to LLINs. This study can inform on the design policies to improve nomadic communities' knowledge of malaria prevention and promoting LLIN use as requested by the national policy against malaria.

Malaria care-seeking and treatment ideation among gold miners in Guyana

BackgroundAlthough miners are a priority population in malaria elimination in Guyana, scant literature exists on the drivers of malaria-related behaviour. This study explores the relationship between gold miners’ malaria-related ideation and the adoption of malaria care-seeking and treatment behaviours including prompt care-seeking, malaria testing, and self-medication.MethodsData are from a cross-sectional quantitative survey of 1685 adult miners between the ages of 18–59 years who live in mining camps in Regions 1, 7, and 8. The analysis focused on miners who reported an episode of fever in the past year (n = 745). Malaria care-seeking and treatment ideation was defined as a composite additive score consisting of the following variables: general malaria knowledge, perceived severity, perceived susceptibility, beliefs, perceived self-efficacy, perceived norms, interpersonal communication, and perceived response efficacy. Multivariable logistic regressions explored the relationship between ideation on care-seeking/treatment behaviours, controlling for confounding variables.ResultsMost miners with a recent episode of fever had perceived risk (92%), self-efficacy (67%), susceptibility (53%) and high malaria knowledge (53%). Overall, miners' care-seeking/treatment ideation score ranged from 0 to 8 with a mean of 4.1. Ideation scores were associated with higher odds of care-seeking for fever (aOR: 1.19; 95% CI 1.04–1.36), getting tested for malaria (aOR: 1.22; 95% CI 1.07–1.38) and lower odds of self-medication (aOR: 0.87; 95% CI 0.77–0.99).ConclusionsA national community case management initiative is using study findings as part of its scale-up, using volunteers to make testing and treatment services more accessible to miners. This is complemented by a multi-channel mass media campaign to improve miners’ ideation. Communication messages focus on increasing miners’ knowledge of malaria transmission and symptoms, encourage positive beliefs about malaria testing and volunteer testers, promote evidence about the effectiveness of testing, and reminders of how quick and easy it is to get a malaria test with the community case management initiative. Study findings also have implications for efforts to eliminate malaria across the Guiana Shield.

Malaria prevention knowledge, attitudes, and practices in Zambezia Province, Mozambique

BackgroundIn Mozambique, socio-economic and cultural factors influence the wide adoption of disease preventive measures that are relevant for malaria control strategies to promote early recognition of disease, prompt seeking of medical care, sleeping under insecticide-treated nets (ITNs), and taking intermittent preventive treatment for pregnant women. However, there is a critical information gap regarding previous and ongoing malaria social and behavioural change (SBC) interventions. The aim of this study is to assess the knowledge, attitudes, practices of beneficiaries of SBC interventions.MethodsA descriptive cross-sectional survey was undertaken in 2018 in two rural districts of Zambezia Province, Mozambique. A structured questionnaire was administered to 773 randomly selected households. Respondents were the adult heads of the households. Descriptive statistics were done.ResultsThe main results show that 96.4% of respondents recalled hearing about malaria in the previous 6 months, 90.0% had knowledge of malaria prevention, and 70.0% of preventive measures. Of the 97.7% respondents that had received ITNs through a mass ITN distribution campaign, 81.7% had slept under an ITN the night before the survey. In terms of source of health information, 70.5% mentioned the role of community volunteers in dissemination of malaria prevention messages, 76.1% of respondents considered worship places (churches and mosques) to be the main places where they heard key malaria prevention messages, and 79.1% asserted that community dialogue sessions helped them better understand how to prevent malaria.ConclusionsResults show that volunteers/activists/teachers played an important role in dissemination of key malaria prevention messages, which brought the following successes: community actors are recognized and people have knowledge of malaria transmission, signs and symptoms, preventive measures, and where to get treatment. There is, however, room for improvement on SBC messaging regarding some malaria symptoms (anaemia and convulsions) and operational research is needed to ascertain the drivers of malaria prevalence and inform the SBC approach.

Rural\u2013urban disparities and factors associated with delayed care-seeking and testing for malaria before medication use by mothers of under-five children, Igabi LGA, Kaduna Nigeria

BackgroundFever in under-five children (U5) is the commonest presenting complaint in general practice and mothers’ recognition is an entry point for fever treatment, including malaria. This study describes rural–urban disparity in fever prevalence in U5, mothers’ malaria knowledge, care-seeking, testing for malaria before anti-malarial medication and the associated factors.MethodsA cross-sectional survey was conducted among 630 mother–child pairs [rural (300) and urban (330)] selected randomly using a multi-stage sampling from 63 villages in Igabi LGA, Kaduna State, Nigeria. Trained female data collectors administered a pre-tested structured questionnaire to collect information on mother–child demographic profiles, malaria knowledge, fever episodes in birth order last child in two weeks prior to survey, blood testing before anti-malarial use, and delayed care-seeking defined as care sought for fever > 48 h of onset. Malaria knowledge was categorized into good, average, and poor if the final scores were ≥ 75th, 50th–74th, and < 50th percentiles, respectively. Frequency, proportions, and odds ratio were calculated. Statistically significant was set at p-value < 0.05.ResultsThe median age (interquartile range) of rural mothers was 30 (IQR, 10) years compared to 27 (IQR, 6) years in urban. Of the 70.0% (441/629) U5 children with fever, 58.5% (258/441) were in rural settlements. A third of the mothers whose child had fever sought care. Mothers in rural settlements were 2.8 (adjusted OR: 2.8, CI 1.8–4.2, p < 0.01) times more likely to delay care-seeking for fever. Other significant factors were poor or no knowledge of malaria transmission, poor perception of malaria as a major health problem, and household size > 5. Also, mothers who had no formal education were four times more likely to receive anti-malarial medications without testing for malaria compared to their educated counterpart (adjusted OR: 4.0, 95% CI 1.6–9.9, p < 0.000).ConclusionsRural–urban disparities existed between fever prevalence in U5 children, care-seeking practices by their mothers, and factors associated with delayed care-seeking and testing the fever for malaria before anti-malarial medication. Fever treatment for high impact malaria elimination in Nigeria needs a context-specific intervention rather than ‘one-size-fits-all’ approach.

Public Awareness of Malaria Diseases and Transmitting Plant: A Case Study of Ahiazu Mbaise, Nigeria

This study intended to determine the influence of knowledge of malaria epidemiology and water-bearing plant and public participation in malaria prevention and control in Ahiazu Mbaise local government area, Imo State. The study was analyzed basedon the two hypotheses were postulated to guide the study. The descriptive survey research design was used, 100 samples wereused and the stratified random sampling technique was adopted to select the respondent for the study. Questionnaires weredistributed to the respondents and used as an instrument in conducting the research, 100 respondents were given the questionnaires all of it was retrieved to facilitate precise results of the investigation. The Pearson correlation analysis was used forthe data analysis and the following result was obtained – That there is a significant relationship between residents’ knowledge ofmalaria transmission and their participation in malaria prevention and control activities in Ahiazu Mbaise Local Government Area, there is a significant relationship between people knowledge of water-bearing plants as a factor that promote the spread ofmalaria and their participation in malaria prevention and control in the Area.

Prevalence of malaria and treatment procurement in three local government areas of Ekiti State, Nigeria

Malaria remains a major health problem in Nigeria. It accounts for over 60% outpatient visit and 30% hospital admission in Nigeria. Ineffective treatment of malaria is also one of the factors responsible for its prevalence. The prevalence of malaria and treatment procurement was studied in Ekiti state, Nigeria. The study was carried out using well-structured questionnaire comprising of three sections A to C, Socio-economic, input and output data; data on method, cost of treatment of malaria and expenditure were obtained. Multistage random sampling technique was adopted. The result obtained showed that males with percentage prevalence of 53% were more infected than females with 47%. Respondent with symptoms of fever and chills was 48.2% while 51.8% complained of headache and pains. 80.3%% of the respondents have knowledge of malaria transmission while 19.7% have no idea. 46.7% of respondents spent less than 1000 naira for treatment procurement while 53.3% spent more than 1000naira. However, there was a significant difference (p&lt;0.05) between males and female's susceptibility to malaria disease. Therefore, as at the time of study, there is prevalence of malaria in the communities despite the knowledge of the respondents on transmission of malaria and treatment procured.

The use of respondent-driven sampling to assess malaria knowledge, treatment-seeking behaviours and preventive practices among mobile and migrant populations in a setting of artemisinin resistance in Western Cambodia

BackgroundMulti-drug-resistant Plasmodium falciparum threatens malaria elimination efforts in Cambodia and the Greater Mekong Subregion (GMS). Malaria burden in the GMS is higher among certain high-risk demographic groups in Cambodia, especially among migrant and mobile populations (MMPs). This respondent driven sampling (RDS) study was conducted in order to determine malaria knowledge, treatment-seeking behaviours and preventive practices among two MMP groups in Western Cambodia.MethodsAn RDS survey of MMPs was implemented in four purposively-selected communes along the Thai–Cambodia border; two in Veal Veang District and two in Pailin Province, chosen due to their sizeable MMP groups, their convenience of access, and their proximity to Thailand, which allowed for comparison with RDS studies in Thailand.ResultsThere were 764 participants in Pailin Province and 737 in Veal Veang District. Health messages received in Veal Veang were most likely to come from billboards (76.5%) and family and friends (57.7%), while in Pailin they were most likely to come from sources like radio (57.1%) and television (31.3%). Knowledge of malaria transmission by mosquito and prevention by bed net was above 94% in both locations, but some misinformation regarding means of transmission and prevention methods existed, predominantly in Veal Veang. Ownership of treated bed nets was lower in Pailin than in Veal Veang (25.3% vs 53.2%), while reported use the night before the survey was higher in Pailin than in Veal Veang (57.1% vs 31.6%). Use of private sector health and pharmaceutical services was common, but 81.1% of patients treated for malaria in Pailin and 86.6% in Veal Veang had received a diagnostic test. Only 29.6% of patients treated in Pailin and 19.6% of those treated in Veal Veng reported receiving the indicated first-line treatment.DiscussionBarriers in access to malaria prevention and case management were common among MMPs, with marked variation by site. Resolving both nation-wide and MMP-specific challenges will require targeted interventions that take into account this heterogeneity.

Community perceptions on outdoor malaria transmission in Kilombero Valley, Southern Tanzania

BackgroundThe extensive use of indoor residual spraying (IRS) and insecticide-treated nets (ITNs) in Africa has contributed to a significant reduction in malaria transmission. Even so, residual malaria transmission persists in many regions, partly driven by mosquitoes that bite people outdoors. In areas where Anopheles gambiae s.s. is a dominant vector, most interventions target the reduction of indoor transmission. The increased use of ITNs/LLINs and IRS has led to the decline of this species. As a result, less dominant vectors such as Anopheles funestus and Anopheles arabiensis, both also originally indoor vectors but are increasingly biting outdoors, contribute more to residual malaria transmission. The study reports the investigated community perceptions on malaria and their implications of this for ongoing outdoor malaria transmission and malaria control efforts.MethodsThis was a qualitative study conducted in two rural villages and two peri-urban areas located in Kilombero Valley in south-eastern Tanzania. 40 semi-structured in-depth interviews and 8 focus group discussions were conducted with men and women who had children under the age of five. The Interviews and discussions focused on (1) community knowledge of malaria transmission, and (2) the role of such knowledge on outdoor malaria transmission as a contributing factor to residual malaria transmission.ResultsThe use of bed nets for malaria prevention has been stressed in a number of campaigns and malaria prevention programmes. Most people interviewed believe that there is outdoor malaria transmission since they use interventions while indoors, but they are unaware of changing mosquito host-seeking behaviour. Participants pointed out that they were frequently bitten by mosquitoes during the evening when outdoors, compared to when they were indoors. Most participants stay outdoors in the early evening to undertake domestic tasks that cannot be conducted indoors. House structure, poor ventilation and warm weather conditions were reported to be the main reasons for staying outdoors during the evening. Participants reported wearing long sleeved clothes, fanning and slapping themselves, using repellents, and burning cow dung and neem tree leaves to chase away mosquitoes.ConclusionsCommunity understanding of multiple prevention strategies is crucial given changes in mosquito host seeking behaviour and the increased incidence of outdoor biting. The current low use of outdoor control measures is attributed largely to limited awareness of outdoor transmission. Improved community understanding of outdoor malaria transmission is critical: efforts to reduce or eliminate malaria transmission will not be successful if the control of outdoor transmission is not emphasized.

Multi-dimensional knowledge of malaria among Nigerian caregivers: implications for insecticide-treated net use by children.

BackgroundPoor malaria knowledge can negatively impact malaria control programmes. This study evaluates knowledge distribution in the domains of causation, transmission, vulnerability, symptoms, and treatment of malaria. It assesses the association between a caregiver’s knowledge about malaria and ownership and use of insecticide-treated nets (ITNs) by children.MethodsSome 1939 caregivers of young children were recruited through a school-based survey in two Nigerian states. A 20-item, multi-dimensional survey instrument was developed and used to rank each caregiver’s knowledge in five dimensions (cause, transmission, vulnerability, symptoms, treatment of malaria). Scores for each domain were used to create an aggregate knowledge score for each caregiver. The outcome measures were ITN ownership, and ITN use the night and week before the study. Regression models were used to evaluate the relationship between caregiver’s knowledge (individual domains and aggregate score) and ownership and use of ITN after controlling for likely confounders.ResultsThe main predictor of ITN use was ITN ownership (r = 0.653; p < 0.001); however, ownership only explains 43 % of variance in net use. Total knowledge index for the study population was significantly associated with both ITN ownership (r = 0.122; p = 0.001) and use (r = 0.095; p = 0.014). The spectrum of caregiver’s knowledge of malaria and its causes captured in the various domains was, however, found to be poor. Fifty percent of the respondents knew that malaria is transmitted by female mosquitoes and 65 % still believe that too much exposure to the sun is a risk factor for malaria. Knowledge of populations most vulnerable to malaria (83 %) and knowledge of malaria transmission (32 %) were the domains with the highest and lowest average correct answers.ConclusionsThere is a need to improve ITN coverage in Nigeria as ITN ownership was associated with ITN use. Additionally, treating knowledge as a multi-dimensional phenomenon revealed that a lot of misperceptions about malaria still exist. Distribution of ITNs through the public/private sector may need to be augmented with tailored behavioural change communication to dispel myths and improve the multi-dimensional knowledge of malaria in the local population.

A household survey to assess community knowledge, attitude and practices on malaria in a rural population of Northern India.

Introduction:An extensive search on PubMed reveals very little in terms of evidence regarding the current knowledge, attitude, and practices (KAP) of the population in general and rural population, in particular, in this part of the country. Therefore, a study was conducted with the aim to assess the communities’ knowledge of malaria transmission, recognition of signs and symptoms, treatment seeking.Materials and Methods:A stratified two-stage design was used to conduct a house-to-house survey using a semi-structured questionnaire in RS Pura block of Jammu District of Jammu and Kashmir State in North India.Results:A total of 300 households were included in the study. However, data on 4 households was found to be incomplete at the time of analysis and, therefore, were excluded. Out of 296 study participants interviewed 65.5% were males, while 34.5% females. All of the study participants (100%) had heard of malaria, and the main source of their information was television/newspaper. 92.5% of the study population considered malaria to be a serious health problem, thus reflecting their attitude to the disease. Regarding practices, 71.6% of the study participants preferred going to doctors at government hospitals for malaria treatment, and 56% were willing to seek medical help in <24 h in case of a child has a febrile episode.Conclusions:Results revealed that KAP among respondents were reasonably good and key sociocultural, and related indicators need to be identified as a part of malaria elimination strategy.

Insecticide treated nets use and its determinants among settlers of Southwest Ethiopia.

BackgroundEthiopia is rapidly increasing insecticide-treated nets (ITNs) coverage to combat malaria, but adequate follow-up and factors affecting use of ITNs is lacking. The aim of this study was to assess determinants of the use of ITNs in a southwest area of Ethiopia.MethodsThis cross-sectional survey was conducted in the Chewaka district settlement area of southwest Oromia from March to May, 2013. Kebeles were stratified by degree of urbanization (rural, peri-urban, or urban). Randomly selected households, which had been freely supplied with at least one ITN, were surveyed using a pre-tested, structured questionnaire administered through household interviews. Logistic regression analysis was used to examine the association between use of ITNs and determinant factors.ResultsOf 574 households surveyed, 72.6 % possessed ITNs and 80 % of these had been used the night before the survey. The most common reasons for the absence ITNs in the household identified in this study were ITNs were old and therefore discarded and that households use ITNs for purposes other than their intended use. The multivariate analysis found that knowledge of malaria transmission by mosquito bites (Adjusted OR = 3.44, 95 % CI: 1.80–6.59), and washing of ITNs at least once by households (Adjusted OR = 2.66, 95 % CI: 1.35–5.26) were significantly associated with an ITN being used by households. The mean possession was 1.59 ITN per household (3.57 persons per an ITN). One hundred fifty four (36.9 %) of ITNs had at least one hole/tear. Among these, 108 (70.1 %) ITNs had at least one hole/tear with greater than 2 cm and 29 (18.8 %) had greater than seven holes/tears.ConclusionsThis study in Southwest Ethiopia showed a high proportion of net ownership compared to a household survey from Ethiopia which included in the World Malaria Report. Despite somewhat high percentages ITN ownership, the study demonstrated there was still a gap between ownership and use of ITNs. Use of ITNs was affected by knowledge of malaria transmission by mosquito bite and washing of ITNs at least once by households. Intensive health education and community mobilization efforts should be employed to attempt to influence these factors that significantly affect ITN use.

Coverage, use and maintenance of bed nets and related influence factors in Kachin Special Region II, northeastern Myanmar.

BackgroundMyanmar is one of the 31 highest burden malaria countries worldwide. Scaling up the appropriate use of insecticide-treated nets (ITNs) is a national policy for malaria prevention and control. However, the data on use, influencing factors and maintenance of bed nets is still lack among the population in Kachin Special Region II (KR2), Northeastern Myanmar.MethodsThe study combined a quantitative household questionnaire survey and qualitative direct observation of households. A Chi-squared test was used to compare the percentages of ownership, coverage, and rates of use of bed nets. Additionally, multivariate logistic regression analysis (MVLRA) was used to analyse factors that influence the use of bed nets. Finally, covariance compared the mean calibrated hole indexes (MCHI) across potential influence variables.ResultsThe bed net to person ratio was 1:1.96 (i.e., more than one net for every two people). The long-lasting insecticidal net (LLIN) to person ratio was 1: 2.52. Also, the percentage of households that owned at least one bed net was 99.7 % (666/688). Some 3262 (97.3 %) residents slept under bed nets the prior night, 2551 (76.1 %) of which slept under ITNs/LLINs the prior night (SUITNPN). The poorest families, those with thatched roofing, those who use agriculture as their main source of family income, household heads who knew that mosquitoes transmit malaria and those who used bed nets to prevent malaria, were significantly more likely to be in the SUITNPN group. However, residents in lowlands, and foothills were significantly less likely to be SUITNPNs. Finally, head of household attitude towards fixing bed nets influenced MCHI (F = 8.09, P = 0.0046).ConclusionsThe coverage and usage rates of bed nets were high, especially among children, and pregnant women. Family wealth index, geographical zones, household roofing, source of family income, household head’s knowledge of malaria transmission and of using bed nets as tools for malaria prevention are all independent factors which influence use of ITNs/LLINs in KR2. Maintaining high coverage, and use rate of bed nets should be a priority for the war-torn population of KR2 to ensure equity and human rights.

Ownership and utilization of insecticide-treated nets (ITNs) for malaria control in Harari National Regional State, Eastern Ethiopia.

IntroductionInsecticide-treated nets (ITNs) stood at center in the current efforts to prevent and control malaria at community and individual levels. Though ITNs are the most prominent measure for large-scale deployment in highly endemic areas their compliance in terms of ownership and usage needs attention. The aim of this study was therefore to determine the ownership and utilization pattern of ITNs in Harari Peoples National Regional state, Ethiopia.MethodsA community based cross-sectional study was conducted in Harari National Regional State from September to October, 2012. A total of 784 households were included from malarious areas. Data were collected by using structured questionnaires and observational checklist.ResultsAbout 57.9% of participants had at least one ITNs. The utilization of ITNs based on history of sleeping under net in the previous night was 73.3%. Regarding proper use of ITNs, 57.9% of respondents demonstrated proper hanging and tucking. Those households with secondary school education (AOR: 1.775(1.047, 3.009)), knowledge about ITNs use (AOR: 2.400(1.593, 3.615)) and knowledge of malaria transmission by bite of mosquito (AOR: 1.653(1.156, 2.365)) have more likely hood to own ITNs.ConclusionITNs Ownership was low as compared to the target by Federal ministry of Health of Ethiopia. Though utilization of ITNs was promising, there are still significant number of participants who demonstrate hanging and tucking improperly. Therefore, health bureau need to work towards increasing the distribution of ITNs per household and also provide health information through health extension workers to enhance regular and proper usage of the ITNs.

The prevalence of malaria among HIV seropositive individuals and the impact of the co- infection on their hemoglobin levels.

BackgroundMalaria and HIV/AIDS are the two most common infections in sub-Sahara Africa. There are hypotheses and study reports on the possible association between these two infections, hence the prevalence and outcome of their co-infection in an endemic population will be important in defining healthcare strategies. A cross sectional study was carried out at the Holy Family Hospital in Techiman, Ghana, between November 2011 and January 2012, to determine the prevalence of malaria among HIV sero-positive patients and its impact on hemoglobin levels.MethodA total of 400 HIV sero-positive participants (292 females and 108 males) aged between 1 and 73 years were randomly sampled for the study. A questionnaire was administered and 2 ml of venous blood samples were drawn for malaria parasites detection, CD4 count and haemoglobin level estimations.ResultsMalaria parasites were detected in 47 (11.75%) of the participants. There was no statistically significant difference between the malaria prevalence rate of females (12.1%) and males (10.2%) P = 0.6047. An overall anaemia prevalence of 67% was observed. Among participants with malaria the anaemia prevalence was 93.6%. The CD4 cell count of all the participants ranged between 3 and 1604 cells/μl with a mean of 386.2 (±274.3) cells/μl. Participants with malaria had CD4 cell count ranged 3 and 512 Cells/μl with the mean being 186.33 (±133.49) Cells/μl. Out of 377 participants (all above 15 years) interviewed on knowledge of malaria transmission and prevention, 87.0% had knowledge on transmission but only 8.5% use in bed nets.ConclusionIt was revealed that almost all the patients with malaria infection were anemic.

Distribution and abundance of dry season indoor mosquitoes in a tropical rural community

Mosquitoes have a world-wide distribution occurring mostly in sub-Saharan Africa where they cause considerable annoyance due to their bites also an important disease vector. The study was undertaken within a six week period in Asa-Obingwu a rural community, in Abia State South eastern Nigeria, to identify the different mosquito vector species and to determine the level of vector host association using blood meal status. In determining the distribution and abundance of mosquito in the study areas, indoor residual spraying using pyrethrum was adopted. The entire Knock down mosquitoes were collected and preserved in labeled bottles accordingly. The mosquitoes were there after identified to species level using dissecting microscope. The results showed that out of 613 mosquito knocked down during the study, 485 (79.1 %) were Anopheles specie, 77 (12.6%) were Aedes specie while 51(8.3 %) were Culex specie.The meal status of the different species encountered showed that Anopheles specie were more fed 324(66.8%) followed by Culex 19 (37.3%) and the least was Aedes 9(11.7 %)specie. These results were significantly different (P<0.05). The average indoor resting density showed that 4 anopheles mosquitoes were found in every house per night as compared to Culex (0.4) and Aedes (0.6) these findings were attributed to the presence of water bodies around the residential areas which were good breeding sites for the vector. The inhabitants were mostly individuals with poor knowledge of malaria transmission and control. It is therefore advocated that government intensify efforts at educating the rural populace on the dangers posed by the presence of the vector.

Do malaria vector control measures impact disease-related behaviour and knowledge? Evidence from a large-scale larviciding intervention in Tanzania

BackgroundRecent efforts of accelerated malaria control towards the long-term goal of elimination had significant impacts in reducing malaria transmission. While these efforts need to be sustained over time, a scenario of low transmission could bring about changes in individual disease risk perception, hindering adherence to protective measures, and affecting disease-related knowledge. The goal of this study was to investigate the potential impact of a successful malaria vector control intervention on bed net usage and malaria-related knowledge.MethodsDar es Salaam’s Urban Malaria Control Program was launched in 2004 with the aim of developing a sustainable larviciding intervention. Larviciding was scaled-up using a stepped-wedge design. Cross-sectional and longitudinal data were collected using a randomized cluster sampling design (2004–2008). Prevalence ratios (PR) for the effect of the larviciding intervention on bed net usage (N = 64,537) and household heads’ knowledge of malaria symptoms and transmission (N = 11,254) were obtained from random effects regression models.ResultsThe probability that individuals targeted by larviciding had used a bed net was reduced by 5% as compared to those in non-intervention areas (PR = 0.95; 95% credible intervals (CrI): 0.94-0.97) and the magnitude of this effect increased with time. Larviciding also led to a decline in household heads’ knowledge of malaria symptoms (PR = 0.88; 95% CrI: 0.83-0.92) but no evidence of effect on knowledge of malaria transmission was found.ConclusionSuccessful control interventions could bring about further challenges to sustaining gains in reducing malaria transmission if not accompanied by strategies to avoid changes in individual knowledge and behaviour. This study points to two major research gaps. First, there is an urgent need to gather more evidence on the extent to which countries that have achieved significant decline in malaria transmission are also observing changes in individual behaviour and knowledge. Second, multidisciplinary assessments that combine quantitative and qualitative data, utilizing theories of health behaviour and theories of knowledge, are needed to optimize efforts of national malaria control programmes, and ultimately contribute to sustained reduction in malaria transmission.

The relationship between knowledge of malaria transmission and malaria prevention and the risk of malaria infection in the coastal region of Batam City in Indonesia

Methods The study was conducted in coastal region the coastal region of Batam City in Indonesia, using crossectional design. This research had got the subject 170 in total included cases and non-cases. The case detection based on the microscopy examination. Then, the subjects were asked using a structured questionnaire consisted of 22 questions regarding the knowledge, perception, and practice everything about malaria. The obtained data was managed based on the median of the all answers and then categorized as good and bad knowledge. The collected data analyzed using c test and spatial analyses using nearest neighbours by Thiessen polygons analysis [1].
