HIV/AIDS-associated beliefs and practices relating to diet and work in southeastern Uganda

To explore beliefs relating to diet, work, and HIV/AIDS among the Busoga of rural southeastern Uganda, a cross-sectional survey of 322 adults was conducted in 2007 in Mayuge district, Uganda. Of these adults, 56 were HIV-infected, 120 had a family member with HIV/AIDS, and 146 were in households without HIV-infected members. More than 74.2% of the adults knew someone with HIV/AIDS, and more than 90% correctly identified transmission modes and prevention methods of HIV. In total, 93.2% believed that a person with HIV should work fewer hours to conserve energy but all the three participant groups reported the same working hours. Also, 91.6% believed that a person with HIV infection should eat special nutritious foods, and the participants with HIV infection reported eating more fruits (p=0.020) and vegetables (p=0.012) than other participants. The participants expressed a consistent set of health beliefs about practices relating to HIV/AIDS

Knowledge, attitudes, and practices related to voluntary counseling and testing (VCT) for HIV among nursing students in Zambia

Access to voluntary counseling and testing (VCT) services has become an important tool in the treatment and prevention of HIV infection. A cross-sectional knowledge, attitudes, and practices (KAP) study was conducted with 50 nursing students in Zambia. All students were aware of where to go for VCT, and 80% had reported using VCT services. However, the participants expressed concerns about privacy and confidentiality related to testing, with most students preferring to seek future VCT at a facility far from their workplace. This ongoing fear of stigma associated with HIV testing was similar to the findings of a recent KAP study conducted among young adults in Bo, Sierra Leone

COMMERCIAL DRINKING WATER QUALITY AND SAFETY IN BO CITY, SIERRA LEONE

Many people who lack reliable access to a quality and safe drinking water source in or near the home rely on commercial drinking water products, such as machine-filled sachet water, that may be of variable quality.A participatory geographic information system was used in conjunction with distribution point and vendor census in the study area to identify a total of 36 water sources across Bo city that  are used for commercial water production.  These include 6 water sources and the production facilities for 10 brands of machine-filled factory-produced water sachets as well as the 10 sources and finished samples for 10hand-tied plastic-bagged water producers. Water samples from all 16 water sources and 20 commercial water products purchased from randomly-selected retail outlets and street vendors were tested for microbiological and physicochemical properties. Workers at all of these facilities were also interviewed about their knowledge and practices.All of the machine-filled sachet waters were free of microbial contamination, but several of the hand- tied water sachets, all filled from unlined local wells, and had coliform bacteria.  Both machine-filled sachet water and hand-tied sachet water had pH levels that were below the World Health Organization’s recommended range. Water with acidic pH can cause corrosion of the metal pipes used with wells and can release those potentially harmful minerals into drinking water. Water factory workers used a variety of water treatment methods to purify their products; hand-tied sachets generally used only cloth filters to purify the water and often stored water in open containers. Improved quality of commercial water products would improve health in Sierra Leone.

A SYSTEMATIC REVIEW OF THE EPIDEMIOLOGY OF MANSONELLIASIS

Although infection with any of the three types of Mansonella species that affect humans is often asymptomatic, a large portion of the world’s population is at risk of this vectorborne filarial nematode infection. No previous global review of the epidemiology of mansonelliasis has been conducted. A systematic review of the literature was conducted. Original research articles that provided population-based mansonelliasis prevalence rates were identified by searching the PubMed database using pre-defined eligibility criteria. Data from each of the forty-six included studies were extracted and compared. Mansonelliasis is a common infection in some parts of west and central Africa and Latin America, with significant variation in prevalence rates over small geographic spaces. The risk of infection increases with age and may be higher in males than females. Despite many similarities, the three agents that cause mansonelliasis have distinct biological, clinical, and epidemiological characteristics. Knowledge about mansonelliasis is important for making differential diagnoses, identifying the possible risks of co-infection with multiple filariases, and addressing the concerns of at-risk populations

Prevalence of Intestinal Parasites in Young Quichua Children in the Highlands of Rural Ecuador

The prevalence of intestinal parasites in young Quichua children was assessed in 20 rural communities in the highlands of Ecuador in August 2005. The caregivers of 293 children aged 12–60 months were interviewed about the status of child health, household socioeconomic and environmental factors, and water-use practices and were requested to collect a faecal sample from the study child. Two hundred three (69.3%) of the 293 children provided faecal samples that were tested for parasites. The overall prevalences of infection for specific agents were Entamoeba histolytica or dispar 57.1%, Ascaris lumbricoides 35.5%, Entamoeba coli 34.0%, Giardia intestinalis (lamblia) 21.1%, Hymenolepis nana 11.3%, Cryptosporidium parvum 8.9%, Chilomastix mesnili 1.7%, Hymenolepis diminuta 1.0%, Strongyloides stercoralis 0.7%, and Trichuris trichiura 0.5%. The prevalence of parasites increased with age. Water storage, water treatment, consistent latrine-use, and participation in a community-based clean water project were not strongly associated with the prevalence of intestinal parasites, although having dirt floors was a risk factor for infection with E. histolytica or dispar and G. intestinalis

Child bed net use before, during, and after a bed net distribution campaign in Bo, Sierra Leone

Background: This analysis examined how the proportion of children less than 5-years-old who slept under a bed net the previous night changed during and after a national long-lasting insecticidal net (LLIN) distribution campaign in Sierra Leone in November–December 2010. Methods: A citywide cross-sectional study in 2010–2011 interviewed the caregivers of more than 3000 under-five children from across urban Bo, Sierra Leone. Chi squared tests were used to assess change in use rates over time, and multivariate regression models were used to examine the factors associated with bed net use. Results: Reported rates of last-night bed net use changed from 38.7 % (504/1304) in the months before the LLIN campaign to 21.8 % (78/357) during the week of the campaign to 75.3 % (1045/1387) in the months after the national campaign. The bed net use rate significantly increased (p \u3c 0.01) from before the campaign to after the universal LLIN distribution campaign in all demographic, socioeconomic, and health behaviour groups, even though reported use during the campaign dropped significantly. Conclusion: Future malaria prevention efforts will need to promote consistent use of LLINs and address any remain- ing disparities in insecticide-treated bed net (ITN) use

Attitudes toward home-based malaria testing in rural and urban Sierra Leone

Background The purpose of this study was to examine malaria testing practices and preferences in Bo, Sierra Leone, and to ascertain interest in and willingness to take a home-based rapid diagnostic test administered by a community health volunteer (CHV) or a trained family member rather than travelling to a clinical facility for laboratory-based testing. Methods A population-based, cross-sectional survey of 667 randomly-sampled rural households and 157 urban households was conducted in December 2013 and January 2014. Results Among rural residents, 69% preferred a self/family- or CHV-conducted home-based malaria test and 20% preferred a laboratory-based test (with others indicating no preference). Among urban residents, these numbers were 38% and 44%, respectively. If offered a home-based test, 28% of rural residents would prefer a self/family-conducted test and 68% would prefer a CHV-assisted test. For urban residents, these numbers were 21% and 77%. In total, 36% of rural and 63% of urban residents reported usually taking a diagnostic test to confirm suspected malaria. The most common reasons for not seeking malaria testing were the cost of testing, waiting to see if the fever resolved on its own, and not wanting to travel to a clinical facility for a test. In total, 32% of rural and 27% of urban participants were very confident they could perform a malaria test on themselves or a family member without assistance, 50% of rural and 62% of urban participants were very confident they could perform a test after training, and 56% of rural and 33% of urban participants said they would pay more for a home-based test than a laboratory-based test. Conclusion Expanding community case management of malaria to include home testing by CHVs and family members may increase the proportion of individuals with febrile illnesses who confirm a positive diagnosis prior to initiating treatment

Enabling methods for community health mapping in developing countries

<p>Abstract</p> <p>Background</p> <p>Spatial epidemiology is useful but difficult to apply in developing countries due to the low availability of digitized maps and address systems, accurate population distributions, and computational tools. A community-based mapping approach was used to demonstrate that participatory geographic information system (PGIS) techniques can provide information helpful for health and community development.</p> <p>Results</p> <p>The PGIS process allowed for the rapid determination of sectional (neighborhood) boundaries within the city of Bo, Sierra Leone. When combined with data about hospital laboratory visits, a catchment area for one hospital in Bo could be established. A survey of households from within the catchment area determined that the average population per household (about 6 individuals) was similar to that found in the 2004 census. However, we also found that the average house was inhabited by more than one household, for an average of 17.5 inhabitants per residential building, which is critical information to know when estimating population size using remote imagery that can detect and enumerate buildings.</p> <p>Conclusions</p> <p>The methods developed in this paper serve as a model for the involvement of communities in the generation of municipal maps and their application to community and health concerns.</p

Lymphedema in a 7-year-old boy infected with Wuchereria bancrofti in Sierra Leone: A case report

We present a case of congenital lymphedema in a 7-year-old boy in Sierra Leone with active filarial infection and penile edema. The genital edema with onset at 6 months of age may have been due to a congenital abnormality in lymphatic drainage. Other possible causes of childhood lymphedema, including Milroy's disease, are discussed
