Lassa fever is of public health concern in West Africa due to its endemic nature. Housing conditions have been revealed to be important sites for primary transmission. This study assessed environmental and housing conditions of a low-income community for factors that could contribute to the transmission of Lassa fever. The study employed a cross-sectional design with a field component. Observational checklist and an interviewer-administered questionnaire were used to assess environmental conditions and respondents’ hygiene knowledge and practices respectively. Rodent traps were also placed in selected households. Data collected were analysed using SPSS Version20. 40% of the respondents had poor housing conditions, 80% had good hygiene practice while 20% had poor knowledge. Respondents with good housing condition were 1.9 times more likely to have good hygiene practice compared to houses with poor housing condition (OR= 1.941, p= 0.009). Rodents trapped from the households were Rattus rattus (43.2%), Rattus fuscipes (38.6%) and Rattus norvegicus (18.2%). Houses with most rats trapped had the poorest housing conditions and hygiene practices. The results suggest that households in the community are susceptible to the transmission of Lassa fever. Therefore, effective awareness campaigns on the transmission of Lassa fever and good hygiene and sanitation practice should be encouraged in and around the home.

Gastrointestinal health is a precursor to general wellbeing in humans. Maintaining good normal gut flora for the health benefits they provide is important. Unfortunately, however, the good gut flora is sometimes dislodged during feeding and treatment with certain drugs. Foods that lead to such gut flora displacement may contain other microorganisms whose actions create unfavourable environmental conditions for resident flora. The principle of removing unwanted harmful gut flora; introducing good microorganisms through ingestion of live microorganisms, known as probiotics or foods that contain specific live microbes of interest is now practiced. Consumption of foods containing probiotics has long been practiced world-wide especially in rural settings and in low-income economies even though such consumptions may be unintended. Presently, careful isolation, characterization and testing of candidate probiotic organisms, has become the norm. This re-emerging phenomenon and the great impact it has on human health is considered here looking at probiotic sources; including foods, the role they play in gastrointestinal health, their mode of action and the disease types where they are beneficial to man including their safety and how their introduction in the �medical menu� in low-income nations can help in combating the rather very �regular� gastrointestinal infections in these countries.

Diseases caused by trypanosomatids (Sleeping sickness, Chagas disease, and leishmaniasis) are a serious public health concern in low-income endemic countries. These diseases are produced by single-celled parasites with a diploid genome (although aneuploidy is frequent) organized in pairs of non-condensable chromosomes. To explain the way they reproduce through the analysis of natural populations, the theory of strict clonal propagation of these microorganisms was taken as a rule at the beginning of the studies, since it partially justified their genomic stability. However, numerous experimental works provide evidence of sexual reproduction, thus explaining certain naturally occurring events that link the number of meiosis per mitosis and the frequency of mating. Recent techniques have demonstrated genetic exchange between individuals of the same species under laboratory conditions, as well as the expression of meiosis specific genes. The current debate focuses on the frequency of genomic recombination events and its impact on the natural parasite population structure. This paper reviews the results and techniques used to demonstrate the existence of sex in trypanosomatids, the inheritance of kinetoplast DNA (maxi- and minicircles), the impact of genetic exchange in these parasites, and how it can contribute to the phenotypic diversity of natural populations.

Unsafe sanitation is an increasing public health concern for rapidly expanding cities in low-income countries. Understanding household demand for improved sanitation infrastructure is critical for planning effective sanitation investments. In this study, we compared the stated and revealed willingness to pay (WTP) for high-quality, pour-flush latrines among households in low-income areas in the city of Nakuru, Kenya. We found that stated WTP for high-quality, pour-flush latrines was much lower than market prices: less than 5% of households were willing to pay the full costs, which we estimated between 87,100–82,900 Kenyan Shillings (KES), or 871–829 USD. In addition, we found large discrepancies between stated and revealed WTP. For example, 90% of households stated that they would be willing to pay a discounted amount of 10,000 KES (100 USD) for a high-quality, pour-flush latrine, but only 10% of households redeemed vouchers at this price point (paid via six installment payments). Households reported that financial constraints (i.e., lack of cash, other spending priorities) were the main barriers to voucher redemption, even at highly discounted prices. Our results emphasize the importance of financial interventions that address the sizable gaps between the costs of sanitation products and customer demand among low-income populations.

AbstractSince the introduction of antibiotics into mainstream health care, resistance to these drugs has become a widespread issue that continues to increase worldwide. Policy decisions to mitigate the development of antimicrobial resistance are hampered by the current lack of surveillance data on antibiotic product availability and use in low-income countries. This study collected data on the antibiotics stocked in human (42) and veterinary (21) drug shops in five sub-counties in Luwero district of Uganda. Focus group discussions with drug shop vendors were also employed to explore antibiotic use practices in the community. Focus group participants reported that farmers used human-intended antibiotics for their livestock, and community members obtain animal-intended antibiotics for their own personal human use. Specifically, chloramphenicol products licensed for human use were being administered to Ugandan poultry. Human consumption of chloramphenicol residues through local animal products represents a serious public health concern. By limiting the health sector scope of antimicrobial resistance research to either human or animal antibiotic use, results can falsely inform policy and intervention strategies. Therefore, a One Health approach is required to understand the wider impact of community antibiotic use and improve overall effectiveness of intervention policy and regulatory action.

Abstract. A Bayesian network (BN) approach is used to model and predict shore-break-related injuries and rip-current drowning incidents based on detailed environmental conditions (wave, tide, weather, beach morphology) on the high-energy Gironde coast, southwest France. Six years (2011–2017) of boreal summer (15 June–15 September) surf zone injuries (SZIs) were analysed, comprising 442 (fatal and non-fatal) drownings caused by rip currents and 715 injuries caused by shore-break waves. Environmental conditions at the time of the SZIs were used to train two separate Bayesian networks (BNs), one for rip-current drownings and the other one for shore-break wave injuries. Each BN included two so-called “hidden” exposure and hazard variables, which are not observed yet interact with several of the observed (environmental) variables, which in turn limit the number of BN edges. Both BNs were tested for varying complexity using K-fold cross-validation based on multiple performance metrics. Results show a poor to fair predictive ability of the models according to the different metrics. Shore-break-related injuries appear more predictable than rip-current drowning incidents using the selected predictors within a BN, as the shore-break BN systematically performed better than the rip-current BN. Sensitivity and scenario analyses were performed to address the influence of environmental data variables and their interactions on exposure, hazard and resulting life risk. Most of our findings are in line with earlier SZI and physical hazard-based work; that is, more SZIs are observed for warm sunny days with light winds; long-period waves, with specifically more shore-break-related injuries at high tide and for steep beach profiles; and more rip-current drownings near low tide with near-shore-normal wave incidence and strongly alongshore non-uniform surf zone morphology. The BNs also provided fresh insight, showing that rip-current drowning risk is approximately equally distributed between exposure (variance reduction Vr=14.4 %) and hazard (Vr=17.4 %), while exposure of water user to shore-break waves is much more important (Vr=23.5 %) than the hazard (Vr=10.9 %). Large surf is found to decrease beachgoer exposure to shore-break hazard, while this is not observed for rip currents. Rapid change in tide elevation during days with large tidal range was also found to result in more drowning incidents. We advocate that such BNs, providing a better understanding of hazard, exposure and life risk, can be developed to improve public safety awareness campaigns, in parallel with the development of more skilful risk predictors to anticipate high-life-risk days.

People often form perceptions about how prevalent a behavior is in a social group. However, these perceptions can be inaccurate and biased. While persistent undesirable practices in low-income countries have drawn global attention, evidence regarding people’s perception of how prevalent these practices are is scarce. Among those harmful practices, open defecation in India remains a significant public health concern, where it perpetuates the vicious cycle of disease and poverty. In this study, we focus on measuring the perceived prevalence of open defecation among respondents in Bihar, India. We examined the bias in perceived prevalence, which is defined as a pattern of deviation from the actual prevalence of open defecation. Results showed that respondents who defecate in the open overestimate the prevalence of open defecation, whereas those who consistently use toilets underestimate it. This finding suggests a false consensus bias in the perceived prevalence of open defecation. Scholars, policymakers, and program implementers who seek to correct misperceptions about open defecation by broadcasting real prevalence should be aware of biases in the perceived prevalence and address them in behavior change interventions.

The Supplemental Nutrition Assistance Program (SNAP) provides access to healthy food for low-income individuals and households. Food security, however, does not necessarily achieve higher diet quality for beneficiaries. Diet quality is an important consideration for the development and management of chronic illness, a significant public health concern. In this study, we review incentives and disincentives implemented to improve the diet quality, the evidence on SNAP including benefits, challenges, and the politics of funding. New interventions and policies will be needed in order to improve the overall diet quality of SNAP households. SNAP should align with nutritional science to meet national public health goals. Nurses are trusted advocates for patients and the public and are uniquely positioned to aid in this effort. Informed by evidence, nurses willing to leverage their influence, can lead this needed change.

Introduction. Personal hygiene is essential to the current paradigm shift towards predictive, preventive, and personalized medicine, which enables the prediction and prevention of infectious disease outbreaks. Objective. The aim of this paper was to evaluate the personal hygiene practices among university students aiming at providing a basis for preventive and predictive medical interventions and to make future efforts improve target interventions for young people. Methods. The study was conducted using a cross-sectional study. Validated instruments that related personal hygiene practices were used to obtain quantitative data from 412 tertiary students from seven universities in Accra, Ghana. The resulting data were analyzed with IBM-SPSS, version 23. Results. There were more female respondents (54.4%) in the study than male respondents (45.6%). Respondents between the age group of 19-24 years constituted majority (59.7%) of the respondents in the study. Respondents from urban areas exhibited good hygiene practice compared to those from urban residences. There was a significant association between residence and hygiene practice (χ2=17.8, P≤0.001). We also observed that those respondents within the upper class in society had a poor hygiene practice, compared to the Lower Class and Middle Class respondents. Lack of education (63.1%) was observed as the main barrier to personal hygiene among the respondents. Future of the society depends on the health of its youth. Conclusion. A significant number of students are not actively practicing good hygiene. There is a need for deployment of preventive medicine interventions targeted at young people. It calls for improvement in methods of hygiene education for young people in tertiary institutions and the inclusion of hygiene in school curricula.

Background. Ear, nose, and throat (ENT) diseases are an oft overlooked global health concern. Despite their high prevalence and associated morbidity and mortality, ENT diseases have remained neglected in health care delivery. In Zambia and many other low-income countries, ENT services are characterized by poor funding, unavailable surgical procedures, and erratic supply of essential drugs. Objective. To investigate ENT service provision in Zambia with regard to availability of surgical procedures and supply of essential drugs. Methods. A descriptive cross-sectional survey was conducted using a piloted structured questionnaire between 17 January 2017 and 2 January 2018. Included in the study were the 109 hospitals registered with the Ministry of Health (MoH) across the 10 provinces of Zambia. Results. Of the participating hospitals, only 5.9% (n=1) and 40% (n=2) of Second-Level Hospitals (SLH) and Third-Level Hospitals (TLH), respectively, carried out tympanoplasty, myringotomy, and grommet insertion (M+G). Frontal trephination and external ethmoidectomy were offered in 11.7% (n=2) and 40% (n=2) of SLH and TLH, respectively. While tracheostomy (39.3%, n=24), tonsillectomy (27.9%, n=17), and adenoidectomy (27.9%, n=17) were the most widely performed head and neck procedures, laryngectomy was carried out by 1 hospital. Between 14.8% (n=9) and 36.1% (n=22) of hospitals lacked antibiotic and/or antiseptic ear drops. Despite 96.7% (n=59) of the respondents acknowledging ENT as an important branch of clinical practice, only 15.3% (n=4) of the hospitals had a budget for ENT. Also, 6.6% (n=4) of the respondents thought the discipline of ENT had received enough attention. Conclusion. ENT service delivery in Zambia is limited with regard to performed surgical procedures and availability of essential drugs, necessitating urgent intervention. The findings from this study may be used to direct national policy on the improvement of provision of ENT services in Zambia.
