Impacts of COVID-19 outbreaks on the lower-income groups and attainments of SDGs: a study of the fast-growing commercial capital city, Chittagong, Bangladesh

PurposeThe emergence of COVID-19 and its spread led to severe social, economic and livelihood impacts around the world. This study documented the socioeconomic impacts of COVID-19 outbreaks and lockdown on the lower-income groups. Also illustrated the impacts on the attainment of SDGs in the context of the slums of Chittagong City.Design/methodology/approachBoth qualitative and quantitative data have been collected from the 150 respondents through questionnaire surveys in the slums.FindingsThe lockdown led to the decrease of 90% of the respondents' income level and affected the livelihoods of 97.33% of the respondents, with an overall score of 3.22 ± 0.67 on a four-point Likert-type scale. About 96.67% of respondents' psychological conditions have been affected high to extreme, with an overall score of 3.19 ± 0.68. The pandemic affected 74.67% of respondents' food habits, 95.33% of respondents' child education, increased domestic violence and deteriorated social security, basic service facilities and hygiene practices among the slum dwellers. The severity of COVID-19 outbreaks on the lower-income people makes it critical for the government to attain the SDG 1, SDG 2, SDG 3, SDG 4, SDG 5 (Target 5.1, 5.2) SDG 6 and SDG 16.Originality/valueThe findings of the study will help governments, policymakers, international organizations to adopt measures to mitigate the effects of the outbreaks.

Environmental and Occupational Health Exposures and Outcomes of Informal Street Food Vendors in South Africa: A Quasi-Systematic Review.

Introduction: Informal street vending is a form of informal employment, and occupational conditions for people within this group have been proven to be detrimental to their health. Two independent reviewers carried out a systematic evaluation of the existing literature in South Africa on environmental and occupational exposures, as well as the health effects faced by informal street food vendors. Methods: 354 published publications were reviewed and 9 were included, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: The evidence showed that informal street vendors are exposed to workplace risks that affect their health and wellbeing. Non-enclosed vendor stalls and frequent use of open fires were among the risk concerns. Vendors are vulnerable to gastrointestinal diseases such as salmonellosis and respiratory infections such as influenza and COVID-19 due to inadequate access to water, waste disposal facilities, and basic hygiene awareness and practices. Exposure to air pollutants increased the risk of respiratory and urinary illnesses and an impact on the reproductive health of female street vendors. Conclusions: This investigation demonstrated the difficulties in complying with the requirements of the Regulations Governing General Hygiene Requirements for Food Premises, the Transport of Food, and Related Matters (no. R638 of 22 June 2018) and the Occupational Health and Safety (OHS) Act (no. 85 of 1993). Within South African borders, there is a scarcity of research on occupational exposures and health effects in this occupation. As a result, eliminating or preventing these occupational exposures should be at the top of government and stakeholder agendas. The majority of the research was carried out in KwaZulu Natal and used a quantitative, cross-sectional technique. Other designs, including cohorts, time series, and randomized intervention trials, were underutilized.

Telemonitoramento da condição de saúde bucal de pessoas com doença de Parkinson em tempos de Covid-19

Abstract Introduction The elderly are among those most affected by Covid-19, and among them are people with Parkinson's disease. Social distancing, due to the coronavirus, has led to new strategies and tools for health monitoring. Objective To describe the oral health conditions, using telemonitoring, of people with Parkinson's disease during the Covid-19 pandemic. Material and method This is an analytical, quantitative, cross-sectional study. The tool used was the video call. The telephone contacts (n=154) were obtained from lists of patients in the Pro-Parkinson Extension Program at the Federal University of Pernambuco. A semi-structured questionnaire was used to gather sociodemographic data and daily oral hygiene practices for teeth and dentures, and whether or not the participant needed dental treatment, during the Covid-19 pandemic. Result The final sample consisted of 64 Parkinsonian patients. Regarding oral health care, the frequency of hygiene in this period was three times a day among 48.44% of participants, with toothbrush and toothpaste being the items most used for this task. More than half of the sample used dental prostheses. The most common oral health problems during this isolation period were pain, mouth sores and the need for tooth extraction. Conclusion Telemonitoring was essential because it was noted that these patients were deficient in their knowledge of basic hygiene practices and in information on oral health, as well as in the care of dental prostheses.

Prevalence and Characterization of Methicillin-Resistant Staphylococcus aureus from Meat Retail Shops and Meat Handlers in the Buea Municipality, Cameroon

Aim: Methicillin-resistant Staphylococcus aureus (MRSA) is a notorious multidrug-resistant biovar of S. aureus associated with infections that result in high morbidity and mortality in humans and animals. Its persistence in both host and non-host environments adds a major ecological dimension to the problem, thereby making it a one health challenge. This study determined the prevalence and antibiotic resistance patterns of MRSA from meat retail shops and meat handlers in the Buea municipality in addition to basic hygiene practices implemented in the meat retail shops.
 Study Design: In this cross-sectional study, a total of 260 samples (comprising 52 swabs each from weighing balances, butchering slabs, cutting knives, hands of meat handlers and meat samples) were randomly obtained and subjected to microbiological analysis. Data on sociodemographic characteristics of meat handlers and basic hygiene practices were captured in a questionnaire.
 Methodology: After enrichment, each sample was inoculated on mannitol salt agar and DNA extracted from presumptive S. aureus isolates for detection of the nuc gene. MRSA was identified by oxacillin disk diffusion and confirmed by amplification of the mecA gene. All MRSA isolates were challenged with 10 commonly used antibiotics using the Kirby-Bauer disk diffusion method.
 Results: A total of 27 MRSA isolates were recovered from hand swabs (5.8%), meat (15.4%), knives swabs (21.2%) and butchering slabs (9.6%). All (100%) MRSA were resistant to ampicillin and cefepime followed by ofloxacin (92.6%), ciprofloxacin (81.5%) and vancomycin (37%). High susceptibility was observed for gentamicin (100%) and amikacin (100%). All isolates were multidrug-resistant and comprised 11 antibiotypes. Most meat handlers (71.2%) did not have basic meat safety training, while 90.4% of the meat retail shops did not have a nearby water source.
 Conclusion: Our results indicate that meat retail shops could be a potential reservoir of MRSA in the environment and meat handlers need more basic meat safety training.

Cross-contamination of lettuce with Campylobacter spp. via cooking salt during handling raw poultry.

Campylobacter spp. are the most common bacterial pathogens associated with human gastroenteritis in industrialized countries. Contaminated chicken is the food vehicle associated with the majority of reported cases of campylobacteriosis, either by the consumption of undercooked meat or via cross- contamination of ready-to-eat (RTE) foods during the handling of contaminated raw chicken parts and carcasses. Our results indicate that cooking salt (used for seasoning) is a potential vehicle for Campylobacter spp. cross-contamination from raw chicken to lettuce, through unwashed hands after handling contaminated chicken. Cross-contamination events were observed even when the chicken skin was contaminated with low levels of Campylobacter spp. (ca. 1.48 Log CFU/g). The pathogen was recovered from seasoned lettuce samples when raw chicken was contaminated with levels ≥ 2.34 Log CFU/g. We also demonstrated that, once introduced into cooking salt, Campylobacter spp. are able to survive in a culturable state up to 4 hours. After six hours, although not detected following an enrichment period in culture medium, intact cells were observed by transmission electron microscopy. These findings reveal a “novel” indirect cross-contamination route of Campylobacter in domestic settings, and a putative contamination source to RTE foods that are seasoned with salt, that might occur if basic food hygiene practices are not adopted by consumers when preparing and cooking poultry dishes.

Assessment of awareness and hygiene practices regarding COVID-19 among adults in Gaza, Palestine

Coronavirus disease 2019 (COVID-19) has spread worldwide and become an emerging life-threatening pandemic disease since 2019. This study aimed to evaluate the basic knowledge, awareness, personal hygiene and healthy practices regarding COVID-19 during its outbreak among the Palestinian population in the Gaza Strip. It is a cross-sectional survey carried out between July and August 2020 and included 458 participants, aged 18 years or older, belonging to the five Gaza Strip governorates, Palestine, with a variety of socio-economic status. Sociodemographic data and data on COVID-19 knowledge, awareness, personal hygiene and healthy practices were collected via email and social media applications (WhatsApp and Facebook) from the study participants. Statistical analyses were performed using Vr 22 of the SPSS software. Overall, the mean ± SD age of the participants was 26.5 ± 4.2 years. Our findings showed that most of the Gazan adults had very good knowledge regarding COVID-19 in terms of host sources, causative agents, incubation period, symptoms, transmission, treatment and prevention. Additionally, most of the participants had a high level of personal hygiene and healthy practices during the COVID-19 outbreak, where personal hygiene and healthy practices against COVID-19 was 77.4%. Furthermore, a higher educational level did not affect the quality of personal hygiene and healthy practice behaviours during the COVID-19 outbreak. Although most of the Gazans had good knowledge regarding the healthy practices, a significant percentage of the population did not practice the hygiene protocol. Despite the majority of the Gazan population having very good knowledge regarding COVID-19 and a high level of personal hygiene and healthy practices during the COVID-19 outbreak, a small proportion require education about avoiding physical contact and maintaining social distancing with others during the pandemic.

ORAL HYGIENE PRACTICES OF FIRST AND FINAL YEAR DENTAL STUDENTS AT FOUNDATION UNIVERSITY: A COMPARATIVE STUDY

Objective: To compare personal oral hygiene practices between first and final year dental students of Foundation University College of Dentistry (FUCD).
 Study Design: Cross sectional study.
 Place and Duration of Study: Foundation University College of Dentistry, Islamabad, from Mar to May 2019.
 Methodology: A pre-structured questionnaire was distributed to students of first and final year BDS classes with questions related to seven basic oral hygiene practices. These included frequency of teeth cleaning, time spent in cleaning teeth, tools used for cleaning teeth, frequency of changing toothbrushes, use of secondary plaque control methods, whether or not students cleaned their tongue, and how often they visited a dentist.
 Results: Only 2 out of 7 practices, (i.e. more frequency of brushing, 45/52 (86.5% in final year vs 25/47 (53.1% infirst year and usage of floss 22/52 (42.3%) in final year vs 9/47 (19.1%) in first year) were found to be significantly better in final year students when compared to first year BDS students with a p-value of 0.012 and 0.04 respectively. The remaining differences did not reach statistical significance.
 Conclusion: When compared with first year BDS students, only 2 out of 7recommended oral hygiene practiceswere found to be better in final year students. Therefore, there is a need for greater emphasis on oral hygienepractices at undergraduate educational years.

WASH infrastructure and practices in primary health care clinics in the rural Vhembe District municipality in South Africa

BackgroundSouth Africa has unique and diverse social and economic factors that have an impact on the provision of basic water, sanitation, hygiene and waste management infrastructure and practices at health care facilities in ensuring patient safety and prevent the spread of diseases.MethodsThe aim of this study was to evaluate water, sanitation and hygiene access and standards at 50 government owned public health care clinics in the rural region of the Vhembe district of South Africa during 2016/2017, using self-observation, an observation checklist, record reviews and interviews with clinic managers. Water quality from all available water sources on the clinic compound was analysed for Total coliform and E. coli counts using the Colilert Quanti-tray/2000 system. The prevalence of pathogenic diarrhea causing E. coli strains was established using multiplex-Polymerase Chain Reaction.ResultsThe health care clinics in the Vhembe District generally complied with the basic WASH services guidelines according to the World Health Organisation. Although 80% of the clinics used borehole water which is classified as an improved water source, microbiological assessment showed that 38% inside taps and 64% outside taps from the clinic compounds had TC counts higher than guideline limits for safe drinking. Similarly, EC counts above the guideline limit for safe drinking water were detected in 17% inside taps and 32% outside taps from the clinic compounds. Pathogenic EAEC, EPEC, ETEC and EHEC strains were isolated in the collected water samples. Although improved sanitation infrastructures were present in most of the clinics, the sanitary conditions of these toilets were not up to standard. Waste systems were not adequately managed. A total of 90% of the clinics had hand washing basins, while only 61% of the clinics had soap present and only 64% of the clinics had adequate signs and posters reminding the staff, care givers and patients to wash their hands.ConclusionsVarious WASH aspects within the primary health care system in South Africa needs to be improved and corrected. A more rigorous system that is inclusive of all role players in the WASH sectors, with regular monitoring and training sessions, should be used.

Mobilizing a Community-Academic Partnership to Provide DIY Handwashing Stations to Skid Row Residents During COVID-19.

The coronavirus (COVID-19) pandemic is having a devastating impact on global health. In the United States and abroad, there is concern for how the novel coronavirus will affect vulnerable populations, including people experiencing homelessness. Individuals who lack stable housing are more likely to have preexisting health conditions and limited access to basic preventative hygiene practices such as handwashing and sanitizing. The situation has become critical in Los Angeles' Skid Row neighborhood, where nearly 5,000 unhoused residents (13% of the city's homeless population) reside on any given night. Community members' concerns have mounted as social and health services in the area have decreased, and early efforts to prevent the transmission of coronavirus did not adequately address the lack of access to handwashing stations and hand sanitizing products. This Practice Note details an academic-community partnership that uses grassroots organizing to provide "do-it-yourself" handwashing stations to the Skid Row neighborhood. We describe how an academic-community partnership was mobilized to establish innovative practices in response to the coronavirus, offering lessons and recommendations for others hoping to do similar work.

SARS-CoV-2 pandemic: An emerging public health concern for the poorest in Bangladesh

The novel coronavirus (SARS-CoV-2) pandemic is now a global crisis and the poorest in Bangladesh are the most vulnerable. With the whole country being subjected to lockdown measures, millions of poor people are unable to go to work and have lost their incomes, leaving them in profound poverty without access to food and basic health services. Furthermore, living in cramped conditions, lack of health awareness, basic hygiene practices, and failing to maintain social distance measures which are inherently present among the poor, put them at an increased risk of SARS-CoV-2 infection. As the pandemic threatens to expand its devastating grip on Bangladesh, the government and the aid organizations must take urgent and comprehensive initiatives to assist those most in need in this unprecedented health crisis.

Pediculosis capitis in Abidjan, Côte d'Ivoire: Epidemiological profile and associated risk factors

Pediculosis capitis (PC) is a parasitic infestation, common in children's communities caused by Pediculus humanus capitis. Various factors including infestation-related stigma, treatment cost and health risks make this infestation deserves special attention. This study aims to determine epidemiological profile of pediculosis capitis twenty years after the last study in Abidjan, Côte d’Ivoire.An epidemiological cross-sectional survey was carried out from April to June 2018 across 40 public primary schools in the ten districts of Abidjan. Data from schoolchildren and parents and/or guardians were collected using a pretested questionnaire after agreement and signature of the informed consent form. Head lice were identified visually with a magnifying glass, and then collected using fine combs and hairbrushes. The positive diagnosis was made by the detection of living lice in the hair.Of the 4, 805 included participants, 28 (0.58%) were hosting living lice in hair. Analysis of associated factors showed that gender related-status was associated with PC. In this case, girls were more affected than boys (p=0.018). Plateau, Treichville and Port Bouët municipalities were the most affected (p=0.018). The length hair was associated with the occurrence of PC (p<0,001). Schoolchildren from families with low monthly income was most infected by PC (p=0.023). Some parameters such as promiscuity and collective use of washing facilities and bedding, were not found to be associated to head lice infestation.This study shows a drastic decrease of PC prevalence in Abidjan corresponding to 97%. This could be due to the improvement in the quality of life and education of the population of Abidjan. The establishment of hygiene committees and the teaching of basic hygiene practices from the first school years have contributed to these achievements. Maintaining these measures will contribute to the sustainable elimination of CP among children in Abidjan.

Food Hygiene Practices at the Ghana School Feeding Programme in Wa and Cape Coast Cities.

Objective The integrity and the wholesomeness of the food served to school pupils cannot be overlooked, especially when one considers the magnitude of health and sanitation issues that are plaguing the West African nations. This study aimed to investigate some of the personal hygiene practices by the pupils and the hygienic conditions in which food is cooked and served to these school-going children under the Ghana School Feeding Programme (GSFP). Design A cross-sectional and descriptive survey research designs were used in the study. Purposive and simple random sampling techniques were employed in selecting participants. Participants. There were 720 respondents for the study, comprising 600 pupils, 60 teachers, and 60 kitchen staff members from 20 schools. Information was obtained using questionnaire, observation, and unstructured interview instruments. Results Findings from the study revealed that the majority of pupils (92% in Wa and 65% in Cape Coast) did not wash their hands with soap under running water. No hand washing centers for pupils were also seen in most of the schools studied. Majority of the cooks did not have health certificate, and neither had attended any in-service training in two years. In both Wa and Cape Coast municipal schools, none of the kitchen staff admitted that pupils and teachers ever complained about the meals they served to the pupils. Conclusion The GSFP in basic schools forms part of the integral diet of the school children; hence, provision of good quality food can affect the health, learning, and physical activities of these children. Observational checklist revealed that most of the kitchen staff do not strictly adhere to basic food hygiene practices, and this affects the wholesomeness of the food served to the children. There is, therefore, a need for kitchen staff training on hygiene and food preparation practices.

COVID-19: An International Public Health Concern.

This review presents a synopsis on the current COVID-19 pandemic, with focus on preventive measures. COVID-19 is a new viral infection, and is in form of a positive-sense, single-stranded RNA Coronavirus which belongs to an expanded group of viruses which were identified six decades ago. Importantly, the new COVID-19 belongs to the group of SARS-CoV, and it originated in bats but infected humans through smuggled pangolins. At first, the mode of transmission of infection was animal-to-person, but person-to-person and community transmission of the virus has been confirmed in many parts of the world. With an incubation period of between two-fourteen days, signs and symptoms of infection are mild to high respiratory illness; characterized with cough, breathing problems (shortness of breath), high temperature (Fever), tiredness (Fatigue) and nausea. Presently, no vaccines or specific treatment is available for COVID-19, in light of the aforementioned; prevention is the only substantial and less expensive option. With the envisaged explosive community transmission of COVID-19 in the coming weeks in places with limited daily testing, especially in African countries, it is recommended among many that social distancing which includes avoiding any form of contact with people; either through greetings, hugging or shaking of hands and large gatherings, avoid contact with animal items, dead or alive animals, sick and dead people from areas experiencing COVID-19 epidemic, and basic hygienic practices like thorough washing of hands with clean water and antiseptic soap for the duration of at least twenty seconds should be practiced always. However, in the absence of the aforementioned, an alcohol-based hand gel should be used on the hands frequently. Furthermore, health care workers should adhere strictly to the standard preventive measures in areas of heightened COVID-19 epidemic.

A comparative study of microbial contamination between public institutional and private residential bottled water dispensers

Bottled water as well as bottled water dispensers is widely used in the United Arab Emirates as a source of drinking water in residential, commercial, and institutional settings. The quality of such waters is of utmost concern as it has the potential to cause waterborne outbreaks, if (re)contaminated. Besides, bottled water dispensers could act as a source of contamination over time, if not cleaned properly on a regular basis. A cross-sectional study was conducted on 40 water samples collected from public and private bottled water dispensers in the emirates of Dubai and Sharjah. Samples were analyzed for heterotrophic plate count bacteria, fecal and total coliforms, and fungal growth. No total and fecal coliforms were detected in any of the samples. Heterotrophic plate counts (HPC) ranged between 0 and 100CFU/100ml, with an overall average of 31CFU/100ml. There was no significant difference between the HPC bacterial levels of public and private bottled water dispensers. However, a significant association (p < 0.05) was found between fungal growth and the location of the bottled water dispenser within the investigated sites. Survey outcomes also highlighted the need to spread awareness and knowledge amongst general public on basic cleanliness and hygiene practices contributing to safe drinking water and the need for stricter monitoring of public bottled water dispensers cleaning schedules.

ASSESSMENT OF BACTERIAL CONTAMINATION LEVELS ON THE SURFACE OF THE BOVINE CARCASSES AT SLAUGHTERHOUSES OF BARISHAL CITY IN BANGLADESH

Background: Meat industries in developing countries including Bangladesh are found to be challenged by severe hygienic and sanitation problems which are associated with heavy bacterial load on the different sites of carcasses and meat. Objectives: The major objectives of this study were to determine the bacterial load at the different risk sites of bovine carcasses and identification of pathogenic bacteria as well as to assess the associated hygienic and sanitation practices with public health significance of the isolated bacteria. Materials and Methods: The study on bacterial load of bovine carcasses was conducted on 200 swab samples of different risk sites of 20 bovine carcasses in the different slaughterhouses of Barishal City Corporation during the period from April to October 2017. The aseptically collected swab samples from different sites of bovine carcasses were processed and analyzed individually by standard bacteriological procedures for Total viable count (TVC), Total coliform count (TCC), Total Staphylococcus count (TSC) and Total Salmonella count (TSAC) and the bacterial species were identified by the conventional aerobic cultural, morphological and biochemical tests. The hygienic status and practices of slaughterhouses and workers were evaluated through a structured questionnaire survey and also a visual inspection. Results: Staphylococcus aureus (78.5%), Salmonella spp. (64.5%) and Escherichia coli (64.0%) were found widely prevalent bacteria on the surface of freshly slaughtered bovine carcasses. The mean TVC of bacteria at pre-and post-washing of the different risk sites of carcasses including neck, shoulder, rump and their used knife and workers’ hand was calculated and highest one was recorded for neck at both pre (8.17 ± 1.22) and post (8.41 ± 0.92) washings. These TVC were found higher compared to standards set by WHO. The TSC was found highest at shoulder site at both pre (7.26 ± 0.94) and post (7.43 ± 1.02) washing, whereas the neck site was found highest contaminated with E. coli (6.69 ± 1.06 and 6.87 ± 1.04) and Salmonella spp.(5.73 ± 1.05 and 6.07 ± 0.92), respectively. The questionnaire survey and visual inspection of slaughter houses revealed that none of the slaughterhouse workers received any training on slaughterhouses management and hygiene, not used any head and hair covering, protective clothes and hand gloves whereas only 25.33% workers washed their hands and 34.67% used clean water at slaughterhouses during processing of carcasses and meat. Conclusions: The slaughtering of the animals on the ground and then skinning and evisceration in the same place under poor hygienic conditions are the major risk factors for heavy bacterial contamination of carcasses which has been recognized as a threat to food safety and consumers health to foodborne illness. Therefore, it requires a serious attention from all relevant authorities to apply and maintain the basic hygienic slaughterhouse practices to prevent the bacterial contamination of carcasses to prevent food borne illness. However, these data should serve as a baseline for future comparisons in measuring the bacteriological status of beef carcasses in other districts and further research works.

The Safe Start trial to assess the effect of an infant hygiene intervention on enteric infections and diarrhoea in low-income informal neighbourhoods of Kisumu, Kenya: a study protocol for a cluster randomized controlled trial

BackgroundSymptomatic and asymptomatic enteric infections in early childhood are associated with negative effects on childhood growth and development, especially in low and middle-income countries, and food may be an important transmission route. Although basic food hygiene practices might reduce exposure to faecal pathogens and resulting infections, there have been few rigorous interventions studies to assess this, and no studies in low income urban settings where risks are plausibly very high. The aim of this study is to evaluate the impact of a novel infant food hygiene intervention on infant enteric infections and diarrhoea in peri-urban settlements of Kisumu, Kenya.MethodsThis is a cluster randomized control trial with 50 clusters, representing the catchment areas of Community Health Volunteers (CHVs), randomly assigned to intervention or control, and a total of 750 infants recruited on a rolling basis at 22 weeks of age and then followed for 15 weeks. The intervention targeted four key caregiver behaviours related to food hygiene: 1) hand washing with soap before infant food preparation and feeding; 2) bringing all infant food to the boil before feeding, including when reheating or reserving; 3) storing all infant food in sealed containers; and, 4) using only specific utensils for infant feeding which are kept separate and clean.ResultsThe primary outcome of interest is the prevalence of one or more of 23 pre-specified enteric infections, determined using quantitative real-time polymerase chain reaction for enteric pathogen gene targets. In addition, infant food samples were collected at 33 weeks, and faecal indicator bacteria (Enterococcus) isolated and enumerated to assess the impact of the intervention on infant food contamination.ConclusionTo our knowledge this is the first randomized controlled trial to assess the effect of an infant food hygiene intervention on enteric infections in a high burden, low income urban setting. Our trial responds to growing evidence that food may be a key pathway for early childhood enteric infection and disease and that basic food hygiene behaviours may be able to mitigate these risks. The Safe Start trial seeks to provide new evidence as to whether a locally appropriate infant food hygiene intervention delivered through the local health extension system can improve the health of young children.Trial registrationThe trial was registered at clinicaltrial.gov on March 16th 2018 before enrolment of any participants (https://clinicaltrials.gov/ct2/show/NCT03468114).

Prevalence of Respiratory Health Symptoms among Landfill Waste Recyclers in the City of Johannesburg, South Africa

In developing countries, waste sorting and recycling have become a source of income for poorer communities. However, it can potentially pose significant health risks. This study aimed to determine the prevalence of acute respiratory symptoms and associated risk factors for respiratory health outcomes among waste recyclers. A cross-sectional study was conducted among 361 waste recyclers at two randomly selected landfill sites in Johannesburg. Convenience sampling was used to sample the waste recyclers. The prevalence of respiratory symptoms in the population was 58.5%. A persistent cough was the most common symptom reported (46.8%), followed by breathlessness (19.6%) and rapid breathing (15.8%). Approximately 66.4% of waste recyclers reported exposure to chemicals and 96.6% reported exposure to airborne dust. A multivariable logistic regression analysis showed that exposure to waste containing chemical residues (OR 1.80, 95% CI 1.01–3.22 p = 0.044) increased the odds of respiratory symptoms. There was a significant difference in respiratory symptoms in landfill sites 1 and 2 (OR 2.77, 95% CI 1.03–7.42 p = 0.042). Occupational health and safety awareness is important to minimize hazards faced by informal workers. In addition, providing waste recyclers with the correct protective clothing, such as respiratory masks, and training on basic hygiene practices, could reduce the risks associated with waste sorting.

Intestinal parasitism in pediatric oncology children receiving chemotherapy: unexpected low prevalence

BackgroundChildren with underlying malignancies and those on chemotherapy are at risk for having intestinal parasitic infections, which can lead to a severe course and death. This cross-sectional study was done to assess the copro-parasitological and copro-molecular prevalence of entero-parasites in children with malignancies and those on chemotherapy. ProcedureStool samples were collected from 137 Egyptian hospitalized cancerous children with different malignancies in the National Cancer Institute, and receiving chemotherapy.Faecal samples were examined microscopically. Genomic copro-DNA was extracted from fecal samples and amplified by 3 separate nPCR assays targeting Cryptosporidium, G. intestinalis and Entamoeba histolytica complex. ResultThe overall prevalence of enteroparasites was 6.6 % (9 cases). Only Giardia copro-DNA was encountered in 2 (1.4%) faecal samples of patients. Coproscopy detected parasites in 7 cases: Blastocystis spp. in 5 cases (3.6%), Hymenolepis nana in 1 case (0.7%) and Ascaris lumbericoides in 1 case (0.7%). ConclusionLow prevalence may be due to patient's use of prophylactic anti-parasitic and anti-fungal drugs, a standard protocol, basic hygienic practices and good nursing all of which are preventive against enteroparasites transmission. Among studied variables only diarrhoeic individuals who had a solid tumor, and soft/liquid stool with mucus and blood were predictors of intestinal parasitism.
