Using urine test strips and filtration techniques, the study found prevalences ranging from 11.88% to 34.53% across the municipalities. Method: Epidemiological data (urine) were collected and examined with test strips to assess the presence of terminal haematuria: the prevalence of infestation and parasite density was quantified using the filtration technique. Socio-demographic and economic factors were recorded using a questionnaire to assess the correlation with disease. Results: Prevalences of 34.53% (N = 48 out of 139), 13.53% (N = 18 out of 133) and 11.88% (N = 17 out of 143) respectively for the municipalities of Aguégués, N’dali and Sô Ava were calculated. The study showed that the variables “age”, “sex”, “religion” and “socio-professional” activity were not significantly correlated with bilharziasis (p > 0.05) and it appears that these factors are not related to bilharziasis in the surveyed households. While age, sex, religion, and socio-professional activity showed no significant correlation with bilharziasis, factors like agriculture, fishing, and place of residence were statistically significant in relation to the disease. Conclusion: The findings suggest that these socio-demographic and economic factors impede the elimination of schistosomiasis in the examined areas.展开更多

Consequently the planet’s geological, biological and ecological systems, including human biology and health are expected to be altered. These effects are set to include an increase in adverse climate and weather events. The developing world carries a disproportionate burden of health implications that result from extreme climate and weather events, largely because they have limited capacity to respond to the cumulative impacts resulting from climate change. The developed world, however, is not immune to the impacts of climate change despite being highly industrialised and well serviced. In addition, there are a range of documented health impacts associated with climatic factors and a growing number of papers theorising how long-term climate change could impact on health. This article examines literature on the impact of climate change, specifically ultraviolet and water changes on eye health. Geographic and environmental factors that influence eye health, such as location and the spread of blindness causing diseases such as trachoma (bacterial infection of the eye) and onchocerciasis (parasitic disease in the eye) are also examined. The article aims to provide valuable information on the impacts of ultraviolet and water changes that are related to climate change and to propose recommendations that contribute to public health.展开更多
