Soci-Demographic Factors Influencing Intestional Parasitic Infection among Children in Bauchi Local Government Area, Bauchi State

The study was conducted to investigate the socio-demographic factors influencing intestinal parasite infection among children in Bauchi metropolis, Bauchi state. The objectives of the study were to determine the prevalence of human intestinal parasite infection in the area of study, determine the influence of demographic of age of the infected children. Stool samples were collected from five hundred and sixty-two children. The samples were treated and examined microscopically for ova, cyst and eggs of intestinal parasite. The socio-demographic factorss were determined using questionnaire and anthropometric measurement. The result reveals that many children (28.11%) are infected with intestinal parasite. Ascaris lumbricoida, Trichuris trichura, Hookworms and eterobias vermicularis are the common prevailing parasites. While Giadia lamblia is the least common occuring parasite It was also discovered that there is no discrimination of infection among sexes. However, the infection is found to be more common among certain age group (0-4 years). It was concluded that the prevalence of intestinal parasite infection among children is increasing compared to previous studies and the increase is related to poor socio-demographic factors of the children. It is therefore, recommended that there is need to embark on health education on prevention and control measures of intestinal parasite and government should strengthen and support WHO program of providing free antihelminthes drugs to children.

Prevalence of Entamoeba histolytica and Giardia Lamblia Associated with Diarrhea in Children referring to lbn Al-Atheer Hospital in Mosul, Iraq.

Amebiasis and giardiasis are major health problems caused by Entamoeba histolytica and Giardia Lamblia which are the two most common intestinalprotozoan parasiteswith worldwide distribution, especially in developing countries. Both protozoa are spread by thefecal-oralroute; that is to say, by eating or drinking contaminated food or water. The present study aimed to assess the prevalence of E. histolytica and G.lamblia in children with clinical signs of diarrhea referring to Ibn Al-Atheer Hospital in Mosul, Iraq, from January 2019 to December 2020. A total of 2,296 samples were examined by the direct swab of stool method. The patients were within the age range of less than 1 year and above 12 years. The results demonstrated that in 2019 and 2020, the prevalence rates of E. histolytica infections were (152, 13.2%) and (181, 15.7%); moreover, the prevalence rates of G.lamblia were obtained at (10, 0.86%) and (12, 1.04%) (P<0.01). The prevalence of intestinal parasite infections was significantly associated with age and gender, and the prevalence of both E. histolytica and G.lamblia infections were higher in males. Furthermore, the highest and lowest prevalence rates of E. histolytica and G.lamblia infections were reported in the age groups of under 1 year and above 12 years (P<0.05). The high prevalence of protozoan infection in the age group of under 1 year can be attributed to their lack of developed immunity system and resistance. Due to disease transmission, the enhancement of health conditions is of utmost importance in controlling the prevalence of intestinal protozoan parasites.

Intestinal parasitic infection among school children in Dakahlia governorate, Egypt: a cross-sectional study

BackgroundIntestinal parasitic infections are still representing a significant health problem in developing countries including Egypt. School children are highly vulnerable to this type of infection, and they suffered many health consequences. This study was conducted to identify the prevalence of intestinal parasitic infection among school children and its related factors.ResultsThis is a school-based cross-sectional study conducted on 726 school children selected from primary, preparatory, and secondary schools located at Aga district, Dakahlia governorate. A questionnaire sheet including data on the socio-demographic characters of students and their families, environmental and behavioral variables, and gastro-intestinal symptoms was filled. Also, fresh stool samples were collected from each child for microscopic examination to detect eggs, cysts, and trophozoites of intestinal parasites. There were 239 of 726 children with IPIs representing an overall prevalence of 32.9%. The most prevalent parasitic species were E. histolytica (12.3%), G. lamblia (8.5%), H. nana (7.7%), and A. lumbricoides (5.7%). There were significant differences between infected and non-infected children regarding age, educational stage, residence, monthly family income, and maternal education levels. Also, there were highly significant differences between infected and non-infected children regarding all environmental and behavioral variables and the occurrence of GIT symptoms.ConclusionHigh prevalence of IPIs among school children indicates little personal hygiene and poor environmental sanitation. Much more efforts are needed for the application of proper prevention and control strategy.

Intestinal parasitic infections among patients referred to hospitals affiliated to Shiraz University of Medical Sciences, southern Iran: a retrospective study in pre- and post-COVID-19 pandemic.

Intestinal parasitic infections (IPIs) are still a serious public health problem worldwide, particularly in developing countries. The COVID-19 pandemic has affected people’s lifestyles and quality of life. Besides, the prevalence of IPIs is directly associated with environmental sanitation, overcrowding, and personal hygiene. Therefore, the current study aimed to determine the prevalence of IPIs among patients referred to hospitals affiliated to Shiraz University of Medical Sciences by reviewing the available data of hospital information system database in the pre- and post-COVID-19 pandemic. The total data of 13,686 patients referred to hospitals affiliated to Shiraz University of Medical Sciences, southern Iran were collected from March 2019 to March 2021. The overall prevalence of IPIs was found to be 4.4%, and Blastocystis spp. was the most common parasite. The prevalence of protozoan parasites (4.4%) was significantly higher than helminthic parasites (0.04%, P < 0.001). A significant association was observed between IPIs with age, gender, and year (P < 0.05). The prevalence of IPIs among those referred to hospitals before the COVID-19 pandemic was higher than those referred to hospitals during the COVID-19 pandemic (5.8% vs 2.8%), and the differences were statistically significant (P < 0.001). The odds of infection among people investigated during the COVID-19 pandemic was about 40% lower than those investigated before the COVID-19 pandemic (AOR: 0.60, 95% CI: 0.49–0.73, P < 0.001). Our results showed that the prevalence of IPIs has decreased during the COVID-19 pandemic. Improved sanitation, personal hygiene, and health education can be effective in reducing parasitic infections in the COVID-19 pandemic.

Prevalence of Intestinal Parasitic Infection among Pre-School and School-Aged Children Attending to Fann University Hospital, Dakar: Results from Retrospective Analysis

Background: Intestinal parasitic infections represent a major public health problem worldwide. Pre-school and school children have a high risk of infection. The study aimed to determine the epidemiological aspects of intestinal parasitic infections in preschool and school-aged children in Dakar, Senegal. Methods: A retrospective analysis of laboratory records from preschool and school-aged children referred to the Laboratory of Parasitology at the Fann University Hospital in Dakar, Senegal, was carried out. The analysis of the period from 2016 to 2020. Stool samples were examined for the presence of parasites using direct, formal-ether concentration method and the Modified Ziehl Neelsen staining technique. Descriptive and analytic analysis was performed with Stata MP 16.1 software. Results: The overall prevalence of intestinal parasitic infection was 26.8% (429/1603). Blastocystis sp. (34%), Entamaeba coli (28%), Giardia intestinalis (9.6%), Endolimax nana (4.9%) and Ascaris lumbricoides (3.5%) were the common parasites found. Out of the 429 children positive for intestinal parasites, protozoa parasites represent 93.9%. Single infection and mixed infection represent 83.7% and 16.3%. The most prevalent associations were E. coli + Blastocystis sp. (6.3%), E. coli + E. nana (3.3%), and G. intestinalis + Blastocystis sp. (1.9%). Children between the ages of 5 - 10 years and those over 10 years had the most parasitic infections with 28.1% [aOR = 1.91; 95% CI (1.25 - 2.89)] and 27.4% [aOR = 11.92 (1.07 - 3.07)]. According to the year of sample collection, the prevalence was higher in 2017, 32.6% [aOR = 1.49 (1.11 - 2.01]. The prevalence of intestinal parasitic infection was not significantly related to gender (p = 0.87), season (p = 0.85) and symptomatology (p = 0.19). The main clinical symptoms were dysenteric syndrome, dyspeptic disorders, constipation and abdominal pain. Intestinal parasite carriage in patients with acute diarrhea was 20.4%. In HIV positive with chronic diarrhea, the prevalence was 28.6%. Conclusion: The results showed the frequency of intestinal parasites in preschool and school-aged children with a high proportion of protozoa parasites. Children aged over 5 years were more affected. Preventive measures such as health education, improved socio-economic conditions and environmental sanitation are required for reducing their frequency.

Prevalence of intestinal parasitic infections versus knowledge, attitudes and practices of male residents in Brazilian urban slums: a cross-sectional study.

ABSTRACTIntestinal parasitic infections (IPIs) are neglected diseases caused by helminths and protozoa, with the relationships between parasite, host and environment having the potential to produce high morbidity and incapacity to work and mortality in vulnerable areas. This study assessed the prevalence of IPIs concerning socio-environmental conditions and analyzed the knowledge, attitudes and practices related to these diseases among men living in the slums of Rio de Janeiro city, Rio de Janeiro State, Brazil. A cross-sectional study was conducted in an agglomeration of urban slums between 2018 and 2019, with men aged between 20 and 59 years. A socioeconomic status questionnaire and an IPIs knowledge, attitudes and practices questionnaire (KAPQ) were applied. Coproparasitological diagnoses (n=454) were performed using four methods and samples of water for household consumption (n=392) were subjected to microbiological and physicochemical analysis. A total of 624 participants were enrolled. About 40% of the households had “water unsuitable for consumption”. Only one Major Area, MA 3 was not statistically significant for IPIs (AOR=0.75; 95% CI: 0.30-1.88; p=0.55). The overall prevalence of IPIs was 23.8%. Endolimax nana (n=65, 14.3%) and hookworm (n=8, 1.7%) were the most frequently identified parasites. The analysis of the frequency of responses to the KAPQ has shown that men reported to seeking medical care if they were suspicious of IPIs, and around 35% would self-medicate. The results have shown the need to adopt integrated health education practices targeting male residents in urban slums to qualify the care with water for human consumption and promote self-care about IPIs. The household can be considered strategic for Primary Health Care activities for men.

Trends of intestinal parasites among the patients attended at Yabelo General Hospital, Borena Zone, Southern Ethiopia.

Intestinal parasitic infections (IPIs) still cause a major public health problem in developing countries. The most affected populations are those with low socioeconomic status, lack of latrines, inadequate water supply, and poor hygiene like in pastoralist community areas in Ethiopia. Therefore, the study assessed the trends of intestinal parasites among the patients attended at Yabelo General Hospital, Southern Ethiopia, from 2019 to 2021. This retrospective study was conducted on 6108 patients and recorded data from Yabelo General Hospital, which were extracted using a checklist. The complete data of sex, age, and laboratory stool examination result in the record book were included in the study. The data were double-entered using EpiData version 3 and exported to the Statistical Package for Social Sciences version 16 for analysis. The associated factors were analyzed using chi-square and a p-value <0.05 was considered statistically significant. The results were presented in tables, pie charts, and graphs. The overall prevalence of intestinal parasites among the patients who attended Yabelo General Hospital was 48%. Of these, 37.8% (2310) were intestinal protozoa, and 10.2% (624) were intestinal helminths. The study indicates that 59% of patients aged above 45 years were seen infected with intestinal parasites. Of the total suspected patients, 2% (123) were found to have mixed parasite infections. The most reported parasites were Entamoeba histolytica/Entamoeba Dispar 22.6%, Giardia lamblia 15.3%, and Ascaris lumbricoides 1.8%. The trend analysis of intestinal parasites revealed that the overall prevalence declined from 55% in 2019 to 42.3% in 2021. The prevalence of IPI was high among patients seen at Yabelo General Hospital. The analysis showed that the prevalence declined from 2019 to 2021. To sustain the decrease in prevalence, all intestinal parasite prevention measures should be continuously exercised in the area.

Prevalence of Taenia solium taenaisis in Kanchipuram district of Tamil Nadu (India): A cross-sectional study

Background: Taenia solium infections in humans include the infection by the adult tapeworm, these infections are of public health concern and are among the most important afflictions of humans who live in areas of poverty in the developing world and least developed countries. T. solium, a zoonotic disease, transmitted between pigs and humans and among humans, is common in developing countries. Aims and Objectives: The aim of the study was to estimate the detection rate of T. solium taeniasis among patients and random community screening with an indication of intestinal parasitic infection by routine stool examination. Materials and Methods: Collection of stool samples from community and patients. Those who were willing, samples were screened for the cysts/ova/egg by direct microscopic examination by saline, iodine, concentration technique, and modified acid fast staining, were performed to differentiate species of T. solium and Taenia saginata. Results: Overall samples were 2030, out of which 870 stool samples were from community field screening 585 (28.81%) were positive. 1160 from tertiary care center, 668 (32.90%) were positive gave a total prevalence of intestinal parasitic infection of 61.72%. The prevalence of T. solium taeniasis was 194 (9.55%) out of which 92 (4.53%) were from community and 102 (5.02%) were from tertiary care center. Conclusion: The high prevalence of intestinal parasitic infestation might be due to the poor sanitary, contaminated water, and lack of education that is prevalent in the studied region as in other pockets in rural India. Our study showed the usefulness of the Ziehl-Neelsen modified acid-fast stain for identification of Taenia species.

Intestinal parasitic infections among type-2 diabetics seeking healthcare in Sana'a city, Yemen.

Intestinal parasitic infections (IPIs) are common in developing countries, particularly in countries witnessing conflicts and humanitarian crises like Yemen. Type-2 diabetics are among the population categories most vulnerable to a variety of infections, including IPIs. Therefore, this study determined the prevalence and risk factors associated with IPIs among Yemeni type-2 diabetics in Sana'a city. This hospital-based, cross-sectional study recruited 389 type-2 diabetics seeking healthcare in Sana'a from December 2019 to February 2020. Sociodemographic data and risk factors were collected from interviewed participants using a structured questionnaire. Stool samples were collected and examined for parasites using standard techniques. The association of sociodemographic characteristics and risk factors with IPIs was tested using univariate analysis, and a multivariable logistic regression model was developed to identify the independent predictors of IPIs at a significance level of <0.05. The overall prevalence of IPIs among diabetics was 38.6%. Entamoeba histolytica/dispar (30.3%) was the most frequent parasite, followed by Cryptosporidium species (8.2%). The significant independent predictors of IPIs were duration of diabetes mellitus > 10 years (AOR = 1.6; 95% CI: 1.10-2.47, P = 0.029), eating unwashed vegetables/fruits (AOR = 3.2; 95% CI: 1.44-6.92, P = 0.004) and not practicing handwashing before meals (AOR = 2.4; 95% CI: 1.10-5.48, P = 0.035). Over one-third of type-2 diabetics seeking healthcare in Sana'a city are infected with one or more IPIs, predominantly with E. histolytica/dispar, followed by Cryptosporidium species. Such infections cannot be predicted from the sociodemographic characteristics of diabetics. Nevertheless, prolonged duration of diabetes mellitus, eating unwashed vegetables/fruits and not practicing handwashing before meals are independent predictors of IPIs among type-2 diabetics. Large-scale studies are recommended for IPIs among type-2 diabetics with and without gastrointestinal complaints, preferably in comparison to non-diabetics.

National burden of intestinal parasitic infections and its determinants among people living with HIV/AIDS on anti-retroviral therapy in Ethiopia: A systematic review and meta-analysis.

Objectives:The aim of this systematic review and meta-analysis is designed to assess the pooled prevalence and determine risk factors of intestinal parasitic infections among people living with HIV/AIDS on anti-retroviral therapy in Ethiopia.Methods:International databases: PubMed, Web of Science, Cochrane Library, Scopus, PsycINFO, African Journals Online, and Google Scholar were systematically searched. Publication bias was determined using the funnel plot and Egger’s regression tests. Heterogeneity between the studies included in this review was checked by I2 statistic. The DerSimonian and Laird random-effects model was applied to estimate the pooled effect size. Sub-group, meta-regression, and sensitivity analysis were conducted. Overall, meta-analysis was done using Stata version 14 statistical software.Results:Twenty-seven studies with 8946 individuals were included, the estimated pooled prevalence of intestinal parasitic infections among people living with HIV/AIDS on anti-retroviral therapy was 40.24% (95% confidence interval = 33.8–46.6). Based on sub-group analysis, the highest prevalence was observed in the Tigray region 45.7% (95% confidence interval = 7.9–83.5), followed by Oromia region 42.2% (95% confidence interval = 28.8–55.6). Availability of latrine (odds ratio = 26.6, 95% confidence interval = 2.8–15.8), presence of animals at home (odds ratio = 2.7, 95% confidence interval = 1.2–5.8), and source of drinking water (odds ratio = 3.2, 95% confidence interval = 1.3–7.5) were significantly associated with intestinal parasitic infections.Conclusion:These findings indicated that the prevalence of intestinal parasites among people living with HIV/AIDS was high in Ethiopia.

Intestinal Parasitic Infections and Associated Risk Factors Among School-going Children of Age 1-5 years in Dharan, Eastern Nepal

Intestinal parasitic infections have been a major public health burden of developing countries, especially in children. Higher prevalence has been reported among school children, mostly in rural areas of Nepal where water, toilets, hygiene, and sanitation facilities are insufficient. This cross-sectional study was carried out from April to September 2019 to determine the prevalence of intestinal parasitic infections among school-going children1-5 years of Dharan, Nepal, and to assess the associated risk factors. Stool samples were collected in a clean, dry, screw-capped, and wide-mouthed plastic container, kept in an icebox, and transported to the laboratory. Data relating to different risk factors were collected from the parents of 116 participants using a structured questionnaire. The parasites were identified by using the direct wet mount method and formal-ether concentration method. Pearson’s chi-square test was carried out to establish associations between dependent and independent variables using SPSS version 20, and the test considered a greater than &lt; 0.05% as statistically significant with a 95% confidence level. Out of the 116 stool samples, 9 (7.75%) tested positive for the parasitic infections in which 5 (55.5%) were protozoa and 4 (44.45%) were helminths. The prevalent parasites, were Entamoeba histolytica (23%), Hyamenolepis nana (22%), Giardia lamblia (11%), Hookworm (11%), Entamoeba coli (11%), Ascaris lumbricoides (11%), and Intestinal parasitic infections had a significant association with drinking water, bowel syndrome, bathing habit, toilet facility, and washing hands after toilets (p&lt;0.05). Lack of toilets, poor hygiene, and unsafe drinking water were the main risk factors. Improved hygienic practices, safe drinking water, and the use of latrines could lower the rate of parasitic infections.

Burden of Intestinal Parasitic Infections among Children from Five Schools in Bhairahawa, Nepal: A Comparative Cross-Sectional Study

INTRODUCTION: Intestinal parasites cause significant morbidity and mortality, particularly in the tropics including Nepal. The main objective of this study was to explore the burden of intestinal parasitic infections among children in 5 different primary schools in Bhairahawa, Nepal. MATERIAL AND METHODS: This was a cross-sectional comparative study among 408 children from 5 schools in Bhirahawa, Nepal. Stool specimens collected in a plastic container were transported to microbiology laboratory in Universal College of Medical Sciences Teaching Hospital (UCMSTH) immediately. Each sample was examined macroscopically and microscopically for the evidence of parasitic infection. All samples were re-analysed by sedimentation and floatation concentration techniques one after another. RESULTS: The overall prevalence of the parasitic infection was 46.5%. The prevalence varied by the methods that included routine microscopy (23.2%), sedimentation (41.6%) and flotation (8.3%). Ascaris lumbricoides was the most common (29.1%) parasite followed by Entamoeba histolytica (6.1%). Mixed infection was also seen in 7.8% of the samples. Factors such as children’s academic year, age, religion, existing illness, household water sources, meat consumed, domestic animals at house, and recent history of taking anti-helminthics were significantly associated with the intestinal parasitic infections. Prevalence of intestinal parasitic infection was higher in public school (61.1%) compared to private school (37%). Male students had slightly more infections (47.3%) than females (45.7%). CONCLUSIONS: Enteric parasitic infection was very high among the primary schools’ students in Bhairahawa, Nepal. Integrating concentration techniques in routine test can help to detect most of the enteric parasites in stool specimens.

Prevalence and associated risk factors of common intestinal parasitic infections of helminthes among the asymptomatic primary school children at Woldia Town, North Wollo Zone, Amhara Region, in Ethiopia

Background: Intestinal worm infestation is a global health problem and serious concern for the third world countries. The most common intestinal parasites of helminthes that inhabit in human gut include Nematodes (roundworms) and Platyhelminthes (Cestodes and trematodes) which are wide spread throughout the world. Prevention and control of all parasitic infections including helminthes require research work based on the identification of parasites and associated predisposing factors. Objective: The aim of this study was to determine the prevalence and associated risk factors of intestinal parasitic infections of helminthes among the asymptomatic primary school children at Woldia town, North Wollo Zone North Eastern Ethiopia. Methods: The study design was school based cross sectional study from November 2019 to February 2020. The technique of sampling was simple random sampling method and the sample size was computed based on the formula proposed by single population proportion to include 442 study participants. The method of data collection was laboratory microscopic stool examination using direct wet mount and formol-ether concentration technique and the structured questionnaires about the associated risk factors and sociodemographic factors. Analysis of the data was made manually using the thematic framework method including the descriptive statistics Result: The overall prevalence of intestinal parasitic infections of helminths among the asymptomatic primary school children at woldia town was 96(22.7%). The predominant intestinal parasites of helminthes was Ascaries lumbercoides 40 (9.5%) followed by Trichuris trichiura 18 (4.3%), Hymenolopis nana 13 (3.1%) and Hook worms 10 (2.4%). From the overall prevalence of intestinal parasitic infections of helminthes, 96(22.7%), the results obtained by direct wet mount method was 36(37.5%) while the Formol-ether concentration technique method revealed 60(62.5%). Moreover, the result also showed parasitic infections of helminthes were associated with associated predisposing factors. Concluding remarks and recommendations: In this study the overall prevalence of helminthic infections was relatively lower. However the control and intervention of intestinal helminthic infections requires a constant provision of periodic deworming treatment and regular health educations regarding personal hygiene and environmental sanitations.

Prevalence of Intestinal Parasitic Infections and Associated Risk Factors among Pregnant Women Attending Prenatal Care in the Northwestern Ethiopia

Intestinal parasitic infections (IPIs) are the common health problems in developing countries with low socioeconomic and poor living conditions. IPIs affect millions of pregnant women worldwide and may lead to adverse maternal and fetal effects. The present study was aimed at determining the prevalence and associated risk factors of IPIs among pregnant women in Ethiopia. A hospital-based cross-sectional study involving 384 pregnant women was conducted from November 2018 to March 2019. Relevant information on potential risk factors associated with IPIs was gathered using a semistructured questionnaire. Stool samples were collected and examined using wet mount and formol-ether concentration techniques. Logistic regression was used to evaluate the possible association between dependent and independent variables. The overall prevalence of IPIs was 36.7%. Seven species of parasites were identified. The most prevalent intestinal protozoan parasite identified was Entamoeba histolytica/dispar (9.6%) followed by Giardia intestinalis (8.9%). The predominant helminth parasite identified was Ascaris lumbricoides (8.6%), followed by hookworm (5.2%), Taenia spp. (3.6%), Strongyloides stercoralis (1.3%), and Schistosoma mansoni (1.04%). Six pregnant women (1.56%) had infection by two parasite species. The odds of IPIs were higher among illiterates (AOR = 4.63), lowest monthly income earners (AOR = 3.49), primigravida (pregnant for the first time) (AOR = 2.04), those who used unboiled well/stream/river water for drinking (AOR = 14.55), ate soil (AOR = 2.32), and consumed raw vegetables (AOR = 1.91). The prevalence of IPIs in the study subjects was substantially high. Thus, screening of the women for IPIs and providing health education during their antenatal care (ANC) visit are recommended to prevent possible adverse maternal and fetal effects resulting from these infections.

Intestinal Parasitosis and its Association with CD4+ T Cell Count and Viral Load among People Living with HIV in Parasite Endemic Settings of Northwest Ethiopia.

PurposeTo study intestinal parasitosis and its association with viral load and CD4+ T cell count in HIV-infected individuals at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.MethodsA cross-sectional study was conducted from March to June 2019. Three hundred and sixteen study participants were selected using systematic random sampling technique. Sociodemographic and clinical data were collected using structured questionnaire. Stool samples were collected and examined using direct saline, formol ether concentration technique and modified acid fast staining. CD4+ T cell counts and viral load were determined by fluorescence-activated cell sorting (BD FACS) and COBAS Ampliprep/COBAS TaqMan HI2CAP assay, respectively. Data were entered into Epi Data 3.1 and transferred to SPSS version 20 software for analysis. Bivariable and multivariable analyses were performed using a binary logistic regression model. P values of less than 0.05 were considered statistically significant.ResultsThe overall prevalence of intestinal parasitosis was 24.7% (78/316). The most commonly detected parasite was Cryptosporidium species with 5.4% (17/316), followed by Ascaris lumbricoides with 5.1% (16/316). There was a significant association with low CD4+ T cell count (AOR: 3.207; 95% CI: 1.237, 8.317), high viral load (AOR: 2.933; 95% CI: 1.326, 6.489), individuals aged 31–40 years (AOR: 0.305; 95% CI: 0.124, 0.751) and individuals aged 41–50 years (AOR: 0.261; 95% CI: 0.101, 0.671).ConclusionIn this study, prevalence of intestinal parasitic infections was high and was associated with low CD4+ T cell count and high viral load. Therefore, screening of HIV patients, especially those with low CD4+ T-cell count and high viral load, particularly for opportunistic intestinal parasitic infections would be of utmost importance in the efforts to prevent and control opportunistic infections in HIV patients.

Prevalence of Intestinal Parasite Infections in Stray Dogs in Taif Region, KSA

Background: The study of intestinal parasites that occur in stray dogs in the Taif region, KSA, is most important since there is little data available on this subject. Methods: Dog fecal samples were collected from 129 dogs in three different areas. Fecal samples were processed and analyzed by different mount techniques including, parasitological examination, wet-mount preparation and modified Kinyoun’s acid-fast technique. Result: The total prevalence of enteric parasites was 115 positive cases; for helminths was (62.7%) and for protozoa (26.3%). Mixed infection was higher than single infection in three areas. The total prevalence of helminths eggs by different mount preparation recovered from fecal sample examination from single or mixed form E. granulosus, T. canis and T. vulpis was of high infection rate (15.5%), (10.07%), (10.07%), followed by A. lumbercoides (7.7 %). Finally, T. leonine (6.9%), both A. caninum and A. braziliense are of the same percentage (6.2%). Concerning single and mixed protozoa infection, Giardia was of a high prevalence (16.2%), followed by Cryptosporidium (8.5%) and finally E. histolytica (1.5%) in fecal samples of doges. These data revealed that infection levels of parasites in stray dogs in the studied areas were high, knowing that this is the first study for mixed infections between dogs and humans in KSA.

Background A cross-sectional study was conducted from November 2019 to March 2020 to determine the prevalence and associated risk factors of intestinal parasitic infections (IPIs) among pregnant women attending antenatal care (ANC) at Yifag Health Center. Methods The data were collected by a questionnaire interview technique and collecting the stool samples from each pregnant woman. Wet-mount and formol-ether concentration techniques were applied to identify the IPIs. Data were analyzed using SPSS, version 25, and P-values < 0.05 were considered statistically significant. Results Out of the total 280 pregnant women who were selected using a simple random sampling technique, 277 participated in the questionnaire survey and gave stool samples (a response rate of 98.9%). The prevalence of IPIs among pregnant women was 53.4% (95% CI: 47.37, 59.42). Taenia species (18.1%) was the predominant parasite followed by Giardia lamblia (12.6%), Entamoeba histolytica/dispar (9.4%), hookworms (9%), Ascaris lumbricoides (4%), Schistosoma mansoni (3.2%), Hymenolepis nana (0.7%), Strongyloides stercoralis (0.4%), and Enterobius vermicularis (0.4%). Eating raw vegetables (AOR = 2.721; 95% CI: 1.266, 5.849; P=0.010) and poor personal hygiene (AOR = 4.015; 95% CI: 1.456, 11.07; P=0.007) were associated risk factors for G. lamblia, while eating raw meat (AOR = 2.477; 95% CI: 1.252, 4.902; P=0.009) for Taenia species infections. The prevalence of intestinal parasites was high and still a health burden to the pregnant women in the study area. We recommend avoiding eating raw meat, strengthening sanitation and hygiene programs, and routine deworming of pregnant mothers to reduce the burden of IPIs among pregnant women.

Intestinal Parasite Infection and Its Association with Undernutrition among Early Adolescents in Hawassa University Technology Village, Southern Ethiopia

Background. Different studies presented negating findings of the association between intestinal parasite infections (IPIs) and undernutrition among early adolescents in Ethiopia. This study was aimed at assessing intestinal parasite infection and its association with undernutrition among early adolescents in four selected districts of the Sidama region. Method. An institution-based cross-sectional study was conducted in October 2020 among 792 early adolescents. The multistage stage sampling was applied to select 16 primary schools. Simple random sampling was applied to select study participants. Trained data collectors administered questionnaires. Stool samples were collected and analyzed. Anthropometric measurements were taken and indices were calculated using AnthroPlus software. Data were entered into and analyzed by SPSS version 25 software. Association between IPI and undernutrition was measured using multivariable analysis. The outputs are presented using an adjusted odds ratio (AOR) with 95% confidence intervals (CIs). Result. The prevalence of IPI, thinness, and stunting was 32% (95% CI: 28.7%, 35.3%), 17.5% (95% CI: 14.8%, 20.2%), and 21.5% (95 CI: 18.6%, 24.4%), respectively. The higher odds of IPIs were observed among adolescents stunted (AOR = 3.61; 95% CI: 2.44–5.33), those who are thin (AOR = 3.07; 95% CI: 2.02–4.66), those who did not wash their hands after toilet (AOR = 1.89; 95% CI: 1.35–2.66), those who ate raw meat (AOR = 1.50; 95% CI: 1.03–2.14), and those whose family did not own toilet (AOR = 1.71; 95% CI: 1.18–2.46). Conclusion. The prevalence of IPI, thinness, and stunting was high and has public health significance in the study area. IPIs were associated with stunting, thinness, lack of toilets, not washing hands after a toilet visit, and eating raw meat. Strengthening nutrition interventions, deworming programs, and health education on personal and environmental hygiene and sanitation are recommended.

Prevalence of intestinal parasitic infections and their associated risk factors among preschool and school children in Egypt.

Intestinal parasitic infections (IPIs) are among the major public health problems globally, particularly in developing countries like Egypt. This study aimed to evaluate prevalence and risk factors associated with IPIs among preschool and school children in Egypt. A cross-sectional study was conducted on 996 randomly selected preschool and school-aged children in Gharbia governorate during January to April 2018. Stool specimens were examined for the presence of the parasite by direct smear and the formol-ether concentration methods. The overall prevalence of IPIs was 46.2%. Entamoeba histolytica and Ascaris lumbricoides were the most predominant parasites (12.7% per each). This is followed by Enterobius vermicularis (8.6%), Giardia lamblia (7.1%), Cryptosporidium parvum (1.5%), Heterophyes heterophyes (1.4%), Hymenolepis nana (0.7%), Hookworms (0.6%), Fasciola hepatica (0.5%) and Dipylidium caninum (0.4%). Infected children with no symptoms (26.8%) were significantly (P < 0.001) more frequent than those with medical complaint (19.4%). Socio-demographic predictors of IPIs were preschool age (OR = 4.9; P < 0.001; 95%CI 3.3–7.3), living in rural dwellings (OR = 1.96; P < 0.001; 95%CI 1.5–2.5), and belonging to a low-income family (OR = 4.7; P < 0.001; 95%CI 2.3–9.3). The absence of safe drinking water, lack of hand washing (after soil contact, or before meals, or after toilet usage), and eating unwashed vegetables were risk factors for IPIs in the study region (OR = 1.3–6.9, P < 0.001 –P = 0.05). Higher odds for exposure to potential zoonotic parasites were evident in children with pets in their homes for G. lambia and D. caninum (OR = 2.1–8.3; P = 0.02 –P = 0.04), children having household reared ruminants for C. parvum (OR = 10.4; P < 0.001), and children that play with stray animals for E. histolytica and Hookworm (OR = 1.8–6.3; P = 0.04 –P = 0.05)compared to other children with no animal contact. The present study highlights the importance of periodic screening and treatment of IPIs in children, deworming companion animals, and public education for effective prevention of IPIs in children in Egypt.
