RESUMO

BACKGROUND: While 5% of 247 million global malaria cases are reported in Uganda, it is also a top refugee hosting country in Africa, with over 1.36 million refugees. Despite malaria being an emerging challenge for humanitarian response in refugee settlements, little is known about its risk factors. This study aimed to investigate the risk factors for malaria infections among children under 5 years of age in refugee settlements in Uganda. METHODS: We utilized data from Uganda's Malaria Indicator Survey which was conducted between December 2018 and February 2019 at the peak of malaria season. In this national survey, household level information was obtained using standardized questionnaires and a total of 7787 children under 5 years of age were tested for malaria using mainly the rapid diagnostic test. We focused on 675 malaria tested children under five in refugee settlements located in Yumbe, Arua, Adjumani, Moyo, Lamwo, Kiryadongo, Kyegegwa, Kamwenge and Isingiro districts. The extracted variables included prevalence of malaria, demographic, social-economic and environmental information. Multivariable logistic regression was used to identify and define the malaria associated risk factors. RESULTS: Overall, malaria prevalence in all refugee settlements across the nine hosting districts was 36.6%. Malaria infections were higher in refugee settlements located in Isingiro (98.7%), Kyegegwa (58.6%) and Arua (57.4%) districts. Several risk factors were significantly associated with acquisition of malaria including fetching water from open water sources [adjusted odds ratio (aOR) = 1.22, 95% CI: 0.08-0.59, P = 0.002], boreholes (aOR = 2.11, 95% CI: 0.91-4.89, P = 0.018) and water tanks (aOR = 4.47, 95% CI: 1.67-11.9, P = 0.002). Other factors included pit-latrines (aOR = 1.48, 95% CI: 1.03-2.13, P = 0.033), open defecation (aOR = 3.29, 95% CI: 1.54-7.05, P = 0.002), lack of insecticide treated bed nets (aOR = 1.15, 95% CI: 0.43-3.13, P = 0.003) and knowledge on the causes of malaria (aOR = 1.09, 95% CI: 0.79-1.51, P = 0.005). CONCLUSIONS: The persistence of the malaria infections were mainly due to open water sources, poor hygiene, and lack of preventive measures that enhanced mosquito survival and infection. Malaria elimination in refugee settlements requires an integrated control approach that combines environmental management with other complementary measures like insecticide treated bed nets, indoor residual spraying and awareness.

RESUMO

Swimming in public pools can expose bathers to microbiological (e.g., Cryptosporidium) and chemical (e.g., disinfection by-product) hazards, which can lead to recreational water illness. Adequate hygienic behaviours among bathers are important to reduce these risks. However, prior studies have found low compliance with pre-swim showering and avoidance of urinating in pools. We conducted a mixed-methods analysis of online discussion comments to identify key determinants of these two behaviours. We identified relevant discussion threads on Reddit, Quora, and swimming forums. Identified comments were classified as having a positive or negative sentiment towards the behaviour, and they were thematically analyzed according to the Theoretical Domains Framework (TDF). We analyzed 986 comments from 45 threads; 49.8% of comments were classified as expressing a positive sentiment towards the behaviour. Positive sentiments were more commonly expressed towards pre-swim showering compared to avoidance of urinating in pools (60.1 vs. 47.1%). Eleven themes were identified across the following eight TDF domains: beliefs about consequences (n = 362 comments), social influences (n = 298), beliefs about capabilities (n = 240), social/professional role and identity (n = 144), knowledge (n = 138), emotions (n = 137), reinforcement (n = 78), and environmental context and resources (n = 33). Results can help to inform targeted educational and outreach strategies with bathers to encourage increased adoption of hygienic behaviours.

RESUMO

Smallholder farmers dominate the Kenyan dairy sector producing 95% of the total milk. However, several concerns have been raised on the quality and safety of the milk they produce. This study assessed the hygienic practices and microbial safety of milk supplied by smallholder farmers to processors in Bomet, Nyeri, and Nakuru counties in Kenya. Interviews and direct observations were carried out to assess hygiene and handling practices by farmers and a total of 92 milk samples were collected along four collection channels: direct suppliers, traders, cooperatives with coolers, and cooperatives without coolers. Microbial analysis was done following standard procedures and data analysed using GenStat and SPSS. This study revealed that farmers did not employ good hygienic practices in their routine dairy management. They used plastic containers for milking and milk storage (34.2%); they did not clean sheds (47.9%) and did not set aside cows that suffered from mastitis factors (83.6%), resulting in poor microbial quality of raw milk along the collection channels. The highest mean total viable counts (8.72 log10 cfu/ml) were recorded in Nakuru while Nyeri had the highest mean E. coli counts (4.97 log10 cfu/ml) and Bomet recorded the highest mean counts of 5.13 and 5.78 log10 cfu/ml for Staphylococcus aureus and Listeria monocytogenes respectively. Based on all above-mentioned parameters, the microbial load in most samples from all three counties exceeded the set Kenyan standards. Farmer training, improving road infrastructure, use of instant coolers at cooperatives, and quality-based payment systems are recommended as measures to curb microbial growth.

RESUMO

BACKGROUND: Adolescent girls face several challenges relating to menstruation and its proper management. Lack of adequate sanitary products, inadequate water supply, and privacy for changing sanitary pads continue to leave adolescent girls with limited options for safe and proper menstrual hygiene in many low-income settings, including Ethiopia. These situations are also compounded by societal myths, stigmas surrounding menstruation, and discriminatory social norms. This systematic review and meta-analysis aimed to estimate the pooled proportion of safe menstrual hygiene management among adolescent girls in Ethiopia using the available studies. METHODS: We searched PubMed, Google Scholar, African Journal Online (AJOL), Hinari, Science Direct, ProQuest, Direct of Open Access Journals, POPLINE, and Cochrane Library database inception to May 31, 2021. Studies reporting the proportion of menstrual hygiene management among adolescent girls in Ethiopia were considered. The Cochrane Q test statistics and I2 tests were used to assess the heterogeneity of the included studies. Since the included studies revealed considerable heterogeneity, a random effect meta-analysis model was used to estimate the pooled proportion of menstrual hygiene management (MHM). RESULTS: Of 1,045 identified articles, 22 studies were eligible for analysis (n = 12,330 participants). The pooled proportion (PP) of safe MHM in Ethiopia was 52.69% (95%CI: 44.16, 61.22). The use of commercial menstrual absorbents was common 64.63% (95%CI: 55.32, 73.93, I2 99.2%) followed by homemade cloth 53.03% (95%CI: 22.29, 83.77, I2 99.2%). Disposal of absorbent material into the latrine was the most common practice in Ethiopia 62.18% (95%CI: 52.87, 71.49, I2 98.7%). One in four girls reported missing one or more school days during menstruation (PP: 32.03%, 95%CI: 22.65%, 41.40%, I2 98.2%). CONCLUSION: This study revealed that only half of the adolescent girls in Ethiopia had safe MHM practices. To ensure that girls in Ethiopia can manage menstruation hygienically and with dignity, strong gender-specific water, sanitation, and hygiene (WASH) facilities along with strong awareness creation activities at every level are needed.

RESUMO

Tungiasis is caused by the flea tunga penetrans and results in painful skin lesions, skin infections, and permanent disability. However, limited information is available that shows the magnitude of the problem and its risk factors that help for intervention in Ethiopia. The goal of this study was to determine the prevalence and risk factors of tungiasis in children aged 5 to 14 in Mettu woreda in 2020. A community based cross sectional study was conducted among randomly selected kebeles of Mettu woreda, in Southwest Ethiopia. To select study participants, multistage sampling was used. The data were collected through physical examination of the children, interview of parents/guardians of the children, and observation of the home environment using checklists and questionnaires. The descriptive analysis was done for socio-demographic characteristics, prevalence of tungiasis, and housing conditions. A logistic regression analysis was performed, and variables in multivariable regression reported odds ratios and their 95% confidence intervals once the variables were identified using a p-value of 0.05 as a risk factor of statistical significance. The prevalence of tungiasis among children 5-14 years of age in Mettu rural woreda was 52 percent (n = 821). As a risk factor, large family size (AOR: 2.9, 95% CI: 2.13, 4.40); school attendance (AOR: 1.5, 95% CI: 1.02, 2.18), floor inside the house (AOR: 3.8, 95% CI: 1.76, 8.43); having sleeping bed (AOR: 0.16, 95% CI: 0.03, 0.82); access to protected water sources (AOR: 0.24, 95% CI: 0.15, 0.39); access to improved toilet facilities(AOR: 0.63: 95% CI: 0.44, 0.89); access to electric services (AOR: 0.30, 95% CI: 0.15, 0.62); and lack of own farmland (AOR: 0.36, 95% CI: 0.26, 0.50) were found. Therefore, planning and implementation of interventions focus on those risk factors that are particularly important. Water, sanitation and hygiene interventions, and livelihood improvement interventions are required to solve the problem in the setting.

RESUMO

BACKGROUND: WHO promotes the SAFE strategy for the elimination of trachoma as a public health programme, which promotes surgery for trichiasis (ie, the S component), antibiotics to clear the ocular strains of chlamydia that cause trachoma (the A component), facial cleanliness to prevent transmission of secretions (the F component), and environmental improvements to provide water for washing and sanitation facilities (the E component). However, little evidence is available from randomised trials to support the efficacy of interventions targeting the F and E components of the strategy. We aimed to determine whether an integrated water, sanitation, and hygiene (WASH) intervention prevents the transmission of trachoma. METHODS: The WASH Upgrades for Health in Amhara (WUHA) was a two-arm, parallel-group, cluster-randomised trial in 40 rural communities in Wag Hemra Zone (Amhara Region, Ethiopia) that had been treated with 7 years of annual mass azithromycin distributions. The randomisation unit was the school catchment area. All households within a 1·5 km radius of a potential water point within the catchment area (as determined by the investigators) were eligible for inclusion. Clusters were randomly assigned (at a 1:1 ratio) to receive a WASH intervention either immediately (intervention) or delayed until the conclusion of the trial (control), in the absence of concurrent antibiotic distributions. Given the nature of the intervention, participants and field workers could not be masked, but laboratory personnel were masked to treatment allocation. The WASH intervention consisted of both hygiene infrastructure improvements (namely, construction of a community water point) and hygiene promotion by government, school, and community leaders, which were implemented at the household, school, and community levels. Hygiene promotion focused on two simple messages: to use soap and water to wash your or your child's face, and to always use a latrine for defecation. The primary outcome was the cluster-level prevalence of ocular chlamydia, measured annually using conjunctival swabs in a random sample of children aged 0-5 years from each cluster at 12, 24, and 36 month timepoints. Analyses were done in an intention-to-treat manner. This trial is ongoing and is registered at ClinicalTrials.gov, NCT02754583. FINDINGS: Between Nov 9, 2015, and March 5, 2019, 40 of 44 clusters assessed for eligibility were enrolled and randomly allocated to the trial groups (20 clusters each, with 7636 people from 1751 households in the intervention group and 9821 people from 2211 households in the control group at baseline). At baseline, ocular chlamydia prevalence among children aged 0-5 years was 11% (95% CI 6 to 16) in the WASH group and 11% (5 to 18) in the control group. At month 36, ocular chlamydia prevalence had increased in both groups, to 32% (24 to 41) in the WASH group and 31% (21 to 41) in the control group (risk difference across three annual monitoring visits, after adjustment for prevalence at baseline: 3·7 percentage points; 95% CI -4·9 to 12·4; p=0·40). No adverse events were reported in either group. INTERPRETATION: An integrated WASH intervention addressing the F and E components of the SAFE strategy did not prevent an increase in prevalence of ocular chlamydia following cessation of antibiotics in an area with hyperendemic trachoma. The impact of WASH in the presence of annual mass azithromycin distributions is currently being studied in a follow-up trial of the 40 study clusters. Continued antibiotic distributions will probably be important in areas with persistent trachoma. FUNDING: National Institutes of Health-National Eye Institute.

RESUMO

O queijo Minas Artesanal da Canastra é produzido na Serra da Canastra (MG), utilizando leite cru, coalho e pingo, que é uma cultura endógena natural de cada queijaria. Devido ao uso de leite cru, o produto pode veicular microrganismos causadores de doenças veiculadas por alimentos, como Staphylococcus aureus. A caracterização molecular é uma ferramenta importante para avaliar a população microbiana do alimento e direcionar a aplicação de medidas de controle na produção. Este estudo caracterizou a diversidade genética, o potencial de virulência e determinou o perfil de susceptibilidade a antimicrobianos de S. aureus isolados de queijos produzidos na Serra da Canastra. Para o estudo transversal foram analisados 248 isolados de queijos que tinham um tempo de maturação de 22 dias, provenientes de 83 propriedades. Por outro lado, no estudo longitudinal foram analisados outros 197 isolados coletados ao longo do processo de maturação, provenientes de três propriedades. Os isolados foram submetidos a testes bioquímicos para confirmação do gênero e para a confirmação da espécie de S. aureus, foi identificado o gene nuc por meio da técnica de PCR. Além disso, foi pesquisado o gene mecA para a detecção de S. aureus Resistente a Meticilina (MRSA). Após os testes de confirmação, 144 isolados do estudo transversal e 159 do estudo longitudinal foram positivos para o gene nuc, específico para S. aureus. Posteriormente, o perfil clonal foi determinado por Eletroforese de Campo Pulsado (PFGE) utilizando a enzima SmaI e tipagem do locus agr por PCR multiplex. A análise por PFGE foi realizada no programa BioNumerics. A técnica PCR foi realizada para identificar a presença de genes que codificam a produção de hemolisinas, toxina TSST-1, enterotoxinas SEs (SEA, SEB, SEC, SED, SEE, SEG, SEH, SEI, SEJ, SEO, SEM), formação de biofilme e Componentes Microbianos de Superfície que Reconhecem a Matriz de Moléculas Adesivas (MSCRAMMs). Os isolados foram submetidos ao teste de susceptibilidade a antimicrobianos por disco de difusão. Por último, a formação de biofilme em microplaca de 96 poços, em caldo TSB a 37°C, foi verificada pela metodologia de Cristal Violeta. O gene mecA foi detectado em 1,9% dos 445 isolados. A tipagem agrrevelou que 83 (27,4%) dos isolados são do tipo agr-I, 95 (31,4%) agr-II e 43 (14,2%) agr-III, sendo que não foram detectados isolados classificados como agr-IV. A tipagem por PFGE revelou um total de 54 perfis. Assim, um isolado representativo de cada perfil foi utilizado nos demais testes que mostraram a presença dos genótipos spa mais frequentes t127 e t605 (20,58%); t002 (14,70%), seguidos pelos tipos t267 (8,82%); t1234 e t693 (5,8%) e t021, t177, t306, t321, t359, t442, t521, t693 e t5493 (2,9%). Além disso, encontramos a presença dos genes do grupo SEs, sea 1 (1,8%), seh 11 (20,3%), sei 10 (18,5%), sej 7 (12,9%), seg e seo 14 (25,9%), sem 8 (14,8%), e os genes seb, sec, sed, see e tst não foram detectados. Para os genes das hemolisinas, hla foi positivo em todos os isolados e hlb foi positivo em 53 (98,1%) isolados. Os genes positivos para MSCRAMMS foram fnbA, fnbB 18 (33,3%), clfA, clfB e eno 53 (98,1%), fib 44 (81,4%), bbp 4 (7,4%), cna 17 (31,4%) e ebps 10 (18,5%). Por último, os genes de formação de biofilme icaA e icaD estiveram presentes em 38 (70,3%) e 25 (46,2%) dos isolados, respectivamente. Na avaliação de susceptibilidade a antibióticos dos 54 isolados escolhidos, 25 (46,3%) apresentaram maior resistência a penicilina e 13 (24,0%) a tetraciclina. Em menor porcentagem (1,8%), 1 isolado cada foi resistente a eritromicina, cefoxitina, clindamicina, gentamicina, cotrimazol, azitromicina e trimetropim. Além disso, 8 isolados (14,8%) apresentaram resistência intermediaria a tetraciclina, 3 (5,5%) a gentamicina e 1 (1,8%) a tobramicina. No teste para a determinação da formação de biofilme por cristal violeta, 13,7%, foram classificados em isolados não formadores, 60,8% em fracamente formadores, 25,5% moderadamente formadores e nenhum como fortemente formador. A alta diversidade de cepas de S. aureus observada neste estudo mostrou que existem vários tipos de linhagens circulando na região da Canastra. A caracterização revelou uma elevada frequência de genes de virulência e que mais estudos são necessários para avaliar o potencial de produção de enterotoxinas nos queijos artesanais. A melhora dos procedimentos de higienização durante todas as etapas de produção pode ser uma solução para a redução dos níveis de contaminação por S. aureus


Canastra Minas Artesanal cheese is produced in Serra da Canastra (MG), using raw milk, rennet and a natural endogenous culture called pingo. Due to the use of raw milk, the product can carry microorganisms that cause foodborne diseases, such as Staphylococcus aureus. Molecular characterization is an important tool to assess the microbial population of food and guide the application of control measures in production. This study characterized the genetic diversity, virulence potential and determined the antimicrobial susceptibility profile of S. aureus isolated from cheeses produced in Serra da Canastra. A total of 248 isolates from 22 days ripened cheeses were obtained from 83 properties (cross sectional study). Another 197 isolates were collected during maturation (longitudinal study), in three properties. The isolates were submitted to biochemical tests to confirm the genus and to confirm the S. aureus species, the nuc gene was identified by PCR. In addition, the detection of mecA gene was performed for the detection of Methicillin Resistant S. aureus (MRSA). After confirmation tests, 144 isolates from the cross-sectional study and 159 from the longitudinal study were positive for the nuc gene, specific for S. aureus. Subsequently, the clonal profile of the isolates was determined by Pulsed Field Gel Electrophoresis (PFGE) using the SmaI enzyme and typing of the agr locus by multiplex PCR. PFGE analysis was performed using the BioNumerics program. PCR was performed to identify the presence of genes encoding the production of hemolysins, TSST-1 toxin, enterotoxins SEs (SEA, SEB, SEC, SED, SEE, SEG, SEH, SEI, SEJ, SEO, SEM), biofilm formation and microbial surface components recognizing adhesive matrix molecules (MSCRAMMs). The isolates were submitted to the antimicrobial susceptibility test by disc diffusion. Finally, biofilm formation in a 96-well microplate in TSB broth at 37°C was verified by the Cristal Violeta method. The mecA gene was detected in 1.9% of the 445 isolates. Agr typing revealed that 83 (27.4%) of the isolates are agr-I, 95 (31.4%) agr-II and 43 (14.2%) agr-III, and no isolate was classified as agr-IV. PFGE typing revealed a total of 54 profiles. Thus, a representative isolate of each profile was used in the other tests that showed the presence of the most frequent spagenotypes t127, t605 (20.58%); t002 (14.70%), followed by types t267 (8.82%); t1234, t693 (5.8%) e t021, t177, t306, t321, t359, t442, t521, t693 and t5493 (2.9%). In addition, we found the presence of the genes of the SEs group: sea 1 (1.8%), seh 11 (20.3%), sei 10 (18.5%), sej 7 (12.9%), seg and seo 14 (25.9%), sem 8 (14.8%), while seb, sec, sed, see and tst genes were not detected. For hemolysin genes, hla was positive in all isolates and hlb was positive in 53 (98.1%) isolates. The positive genes for MSCRAMMS were: fnbA, fnbB 18 (33.3%), clfA, clfB e eno 53 (98.1%), fib 44 (81.4%), bbp 4 (7.4%), cna 17 (31.4%) and ebps 10 (18.5%). Finally, the biofilm formation genes icaA and icaD were present in 38 (70.3%) and 25 (46.2%) of the isolates, respectively. In the evaluation of antibiotic susceptibility of the 54 isolates, 25 (46.3%) showed greater resistance to penicillin and 13 (24.0%) to tetracycline. In a lower percentage (1.8%), 1 isolate each was resistant to erythromycin, cefoxitin, clindamycin, gentamicin, contrimazole, azithromycin and trimethoprim. In addition, 8 isolates (14.8%) showed intermediate resistance to tetracycline, 3 (5.5%) to gentamicin and 1 (1.8%) to tobramycin. In the test for the determination of biofilm formation by crystal violet, 13.7% were classified as non-forming isolates, 60.8% as weakly forming, 25.5% moderately forming and none as strongly forming. The high diversity of S. aureus strains observed in this study showed that there are several types of strains circulating in the Canastra region. The characterization revealed a high frequency of virulence genes and that further studies are needed to assess the potential for enterotoxin production in artisanal cheeses. The improvement of hygiene procedures during all stages of production can be a solution for reducing the levels of contamination by S. aureus

RESUMO

In addition to diarrheal disease risk, lack of access to safe water may have other indirect effects throughout one's life, such as school and workplace absenteeism, leading to less economic productivity. In contexts with scarce resources and unsafe drinking water, household water treatment and safe storage options such as the Biosand filter (BSF) allows households to directly reduce contamination and increase the quality of their drinking water. This study aimed to develop an understanding of perceived community acceptability and feasibility related to pre- and post-implementation of a BSF pilot project in rural Maasai households in the Ngorongoro Conservation Area (NCA), Tanzania. The study was guided by the Integrated Behavioral Model for Water Sanitation and Hygiene interventions (IBM-WASH) to understand the various factors influencing end-user perceptions of the BSF. In-depth interviews, group discussions and think tanks were conducted among a cross-section of community members, stakeholders, and other actors from May 2016 to September 2017. The data were analyzed using a thematic content analysis approach. A range of perceived contextual, technological, and psychosocial factors were found to potentially affect the acceptability and feasibility of BSF adoption in the NCA, highlighting the complex layers of influences in the setting. Whilst the BSF is seemingly an accepted option to treat water within the NCA, the community identified key barriers that may lower BSF adoption. The application of the IBM-WASH model served as a useful framework for evaluating the introduction of the BSF, identifying insights into contextual, technological, and psychosocial community factors.

RESUMO

INTRODUCTION: in the recent past, cities in sub-Saharan Africa have reported serious cholera outbreaks that last for several months. Uganda is one of the African countries where cities are prone to cholera outbreaks. Studies on cholera in Bangladesh show increased risk of cholera for the immediate household members (contacts) yet the control interventions mainly target cases with little or no focus on contacts. This study aimed to describe the rapid control of cholera outbreaks in Kampala and Mbale cities, Uganda, using, "Cases and Contacts Centered Strategy (3CS)" that consisted of identification and treatment of cases, promotion of safe water, sanitation, hygiene (WaSH) and selective chemoprophylaxis for the contacts. METHODS: a cross-sectional study was conducted in 2015-2016 in the Kampala and Mbale cities during cholera outbreaks. Cholera cases were treated and 816 contacts from 188 households were listed and given cholera preventive packages. Data were collected, cleaned, analysed and stored in spreadsheet. Comparison of categories was done using Chi-Square test. RESULTS: a total of 58 and 41 confirmed cholera cases out of 318 and 153 suspected cases were recorded in Kampala and Mbale cities respectively. The outbreaks lasted for 41 days in both cities. Case fatality rates were high; 12.1% (5/41) for Mbale city and 1.7% (1/58) for Kampala city. Fifty-five percent (210/379) of stool samples were tested by culture to confirm V. choleraeO1. No contacts listed and given cholera preventive package developed cholera. Both sexes and all age groups were affected. In Kampala city, the males were more affected than the females in the age groups less than 14 years, p-value of 0.0097. CONCLUSION: this study showed that by implementing 3CS, it was possible to rapidly control cholera outbreaks in Kampala and Mbale cities and no cholera cases were reported amongst the listed household contacts. The findings on 3CS and specifically, selective antibiotic chemoprophylaxis for cholera prevention, could be used in similar manner to oral cholera vaccines to complement the core cholera control interventions (disease surveillance, treatment of cases and WaSH). However, studies are needed to guide such rollout and to understand the age-sex differences in Kampala city.

RESUMO

Antimicrobial resistance (AMR) is increasingly becoming a threat to global public health, not least in low- and middle-income countries (LMICs) where it is contributing to longer treatment for illnesses, use of higher generation drugs, more expenditure on antimicrobials, and increased deaths attributed to what should be treatable diseases. Some of the known causes of AMR include misuse and overuse of antimicrobials in both humans and animals, unnecessary use of antimicrobials in animals as growth promoters, and lack of awareness among the public on how to protect antimicrobials. As a result, resistant organisms are circulating in the wider environment, and there is a need to consider the One Health approach to minimise the continuing development of AMR. Environmental Health, specifically water, sanitation and hygiene (WASH), waste management, and food hygiene and safety, are key components of One Health needed to prevent the spread of antimicrobial-resistant microorganisms particularly in LMICs and reduce the AMR threat to global public health. The key Environmental Health practices in the prevention of AMR include: (1) adequate WASH through access and consumption of safe water; suitable containment, treatment and disposal of human excreta and other wastewater including from health facilities; good personal hygiene practices such as washing hands with soap at critical times to prevent the spread of resistant microorganisms, and contraction of illnesses which may require antimicrobial treatment; (2) proper disposal of solid waste, including the disposal of unused and expired antimicrobials to prevent their unnecessary exposure to microorganisms in the environment; and (3) ensuring proper food hygiene and safety practices, such as sale and consumption of animal products in which adequate antimicrobial withdrawal periods have been observed, and growing vegetables on unpolluted soil. Environmental Health is therefore crucial in the prevention of infectious diseases that would require antimicrobials, reducing the spread of resistant organisms, and exposure to antimicrobial residues in LMICs. Working with other professionals in One Health, Environmental Health Practitioners have a key role in reducing the spread of AMR including health education and promotion, surveillance, enforcement of legislation, and research.

RESUMO

Lockdowns and just recently, the COVID-19 vaccines, are amongst the disease containment measures instituted globally to check the spread of COVID-19. Prolonged lockdowns are however, not sustainable in low resource economies like Nigeria, where up to 70% of her population live on less than a dollar a day, with the majority, either unemployed, or working in the private/informal sector and depending on daily earnings for survival. If the lockdown remains sustained, it would not be long before the largely poor citizens starve to death. Also, spending over US $3.9 billion on COVID-19 vaccines for more than 200 million Nigerians, as intended by the Nigerian government, is not plausible, given that neglected tropical diseases (NTDs) like Lassa fever, and other more common causes of morbidity and mortality, continue to kill more Nigerians than COVID-19. Public enlightenment of the populace on the need to strictly adhere to non-pharmacologic preventive measures, including social distancing, use of face masks, good personal hygiene, covering of the mouth and nose when coughing and sneezing, frequent hand washing and sanitizing with alcohol-based hand-sanitizers and disinfection of surfaces, is what is sustainable, feasible and compatible with the economic reality in our setting. As Sir Robert Hutchison, the highly revered doyen of medicine, wrote in his petition over 85 years ago, "And from making the cure of the disease more grievous than the endurance of the same, Good Lord, deliver us", we must be careful not to make the cure of COVID-19 worse than COVID-19 itself.

RESUMO

Nearly all mass gathering events worldwide were banned at the beginning of the COVID-19 pandemic, as they were suspected of presenting a considerable risk for the transmission of SARS-CoV-2. We investigated the risk of transmitting SARS-CoV-2 by droplets and aerosols during an experimental indoor mass gathering event under three different hygiene practices, and used the data in a simulation study to estimate the resulting burden of disease under conditions of controlled epidemics. Our results show that the mean number of measured direct contacts per visitor was nine persons and this can be reduced substantially by appropriate hygiene practices. A comparison of two versions of ventilation with different air exchange rates and different airflows found that the system which performed worst allowed a ten-fold increase in the number of individuals exposed to infectious aerosols. The overall burden of infections resulting from indoor mass gatherings depends largely on the quality of the ventilation system and the hygiene practices. Presuming an effective ventilation system, indoor mass gathering events with suitable hygiene practices have a very small, if any, effect on epidemic spread.

RESUMO

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, the links between poor hygiene, unclean environments and human health cannot be overemphasised, particularly in South Africa with its high incidence of infectious diseases and overburdened health system. One very controllable factor that is often overlooked is the poor disposal of litter and waste management and its adverse effects on public health. By wearing masks, regular handwashing and sanitising, as well as making sure that neighbourhoods and public spaces are clean and safe, the spread of COVID-19 and other diseases can be prevented.

RESUMO

INTRODUCTION: following the global COVID-19 outbreak, the government of Benin implemented preventive measures to stall viral transmission. We sought to evaluate adherence of the Beninese people to these preventive measures, in order to identify predictors of poor adherence and adapt the national response to COVID-19. METHODS: two consecutive online surveys were conducted between May and August 2020. Four hundred and sixty two and 507 adult participants aged 18 years and above responded to the first and second survey respectively, with >70% being males. RESULTS: more than 98% of respondents reported wearing face masks. A five-point adherence score was constituted by scoring observance to key preventive measures (mask use, physical distancing, hand hygiene, coughing hygiene and avoiding to touch one´s face). We observed that the mean adherence scores were fairly stable over time, respectively 4.08 and 4.03 during the first and second survey (p=0.439). Increasing age (aOR=1.043, 95% CI: 1.026 - 1.061; p<0.001) and obtaining COVID-19 information from official sources (aOR=1.628, 95% CI: 1.275 - 2.081; p<0.001) were significantly associated with higher adherence scores in a multivariable model. CONCLUSION: these findings suggest that a wide dissemination of adequate information about COVID-19 would increase adherence, and that targeted efforts should be directed towards increasing the compliance to preventive measures among the younger age groups.

RESUMO

BACKGROUND: Schools, depending on their access to and quality of water, sanitation and hygiene (WASH) and the implementation of healthy behaviours, can be critical for the control and spread of many infectious diseases, including COVID-19. Schools provide opportunities for pupils to learn about the importance of hygiene and WASH-related practice, and build healthy habits and skills, with beneficial medium- and long-term consequences particularly in low- and middle-income countries: reducing pupils' absenteeism due to diseases, promoting physical, mental and social health, and improving learning outcomes. WASH services alone are often not sufficient and need to be combined with educational programmes. As pupils disseminate their acquired health-promoting knowledge to their (extended) families, improved WASH provisions and education in schools have beneficial effects also on the community. International organisations frequently roll out interventions in schools to improve WASH services and, in some cases, train pupils and teachers on safe WASH behaviours. How such interventions relate to local school education on WASH, health promotion and disease prevention knowledge, whether and how such knowledge and school books are integrated into WASH education interventions in schools, are knowledge gaps we fill. METHODS: We analyzed how Kenyan primary school science text book content supports WASH and health education by a book review including books used from class 1 through class 8, covering the age range from 6 to 13 years. We then conducted a rapid literature review of combined WASH interventions that included a behaviour change or educational component, and a rapid review of international policy guidance documents to contextualise the results and understand the relevance of books and school education for WASH interventions implemented by international organisations. We conducted a content analysis based on five identified thematic categories, including drinking water, sanitation, hygiene, environmental hygiene & health promotion and disease risks, and mapped over time the knowledge about WASH and disease prevention. RESULTS: The books comprehensively address drinking water issues, including sources, quality, treatment, safe storage and water conservation; risks and transmission pathways of various waterborne (Cholera, Typhoid fever), water-based (Bilharzia), vector-related (Malaria) and other communicable diseases (Tuberculosis); and the importance of environmental hygiene and health promotion. The content is broadly in line with internationally recommended WASH topics and learning objectives. Gaps remain on personal hygiene and handwashing, including menstrual hygiene, sanitation education, and related health risks and disease exposures. The depth of content varies greatly over time and across the different classes. Such locally available education materials already used in schools were considered by none of the WASH education interventions in the considered intervention studies. CONCLUSIONS: The thematic gaps/under-representations in books that we identified, namely sanitation, hygiene and menstrual hygiene education, are all high on the international WASH agenda, and need to be filled especially now, in the context of the current COVID-19 pandemic. Disconnects exist between school book knowledge and WASH education interventions, between policy and implementation, and between theory and practice, revealing missed opportunities for effective and sustainable behaviour change, and underlining the need for better integration. Considering existing local educational materials and knowledge may facilitate the buy-in and involvement of teachers and school managers in strengthening education and implementing improvements. We suggest opportunities for future research, behaviour change interventions and decision-making to improve WASH in schools.

RESUMO

BACKGROUND: The literature examining healthcare-associated infections (HAI) points to two main problems in conforming to infection prevention and control (IPC) guidelines among healthcare professionals (HP). One is the discrepancy between HPs' behavioral intentions and their implementation in practice. The other refers to how HPs maintain these practices after the intervention stage ends. The method proposed in this study seeks to address both these issues by using the Positive Peviance (PD) approach to focus on the dissemination stage of interventions. The study seeks to offer a method for disseminating 27 PD practices to 135 HPs, among them nurses, nurse assistants and physicians, so as to help them maintain IPC guidelines, offer feedback on the dissemination process and examine the impact of the dissemination stage on changes in their behavior. METHODS: The theoretical model underlying this qualitative research was the Recognition-Primed dDecision (RPD) model, which we implemented in the field of healthcare-associated infections (HAIs). Moreover, we used the Discovery & Action Dialogue (DAD) and Think Aloud (TA) techniques to describe the methodological development of simulations for HPs. Feedback from the HP demonstrators underwent content analysis, while descriptive statistics were used to characterize behavioral changes. RESULTS: HPs' information processing regarding infection prevention shifts from peripheral/automatic processing to intuition and analytical/central processing, turning PD practices into positive norms. The HPs personally experienced finding a solution and made repeated corrections until they overcame the barriers. Most of the HPs (69.4%) reported that the practices were fully implemented, together with additional practices. CONCLUSIONS: Implementation of the dissemination stage indicates that in order for HPs to integrate and assimilate practices that are not in the official guidelines, merely observing simulations is not sufficient. Rather, each staff member must personally carry out the procedures.
