Factors determining vulnerability to diarrhoea during and after severe floods in Bangladesh

This paper identifies groups vulnerable to the effect of flooding on hospital visits due to diarrhoea during and after a flood event in 1998 in Dhaka, Bangladesh. The number of observed cases of cholera and non-cholera diarrhoea per week was compared to expected normal numbers during the flood and post-flood periods, obtained as the season-specific average over the two preceding and subsequent years using Poisson generalised linear models. The expected number of diarrhoea cases was estimated in separate models for each category of potential modifying factors: sex, age, socio-economic status and hygiene and sanitation practices. During the flood, the number of cholera and non-cholera diarrhoea cases was almost six and two times higher than expected, respectively. In the post-flood period, the risk of non-cholera diarrhoea was significantly higher for those with lower educational level, living in a household with a nonconcrete roof, drinking tube-well water (vs. tap water), using a distant water source and unsanitary toilets. The risk for cholera was significantly higher for those drinking tube-well water and those using unsanitary toilets. This study confirms that low socio-economic groups and poor hygiene and sanitation groups were most vulnerable to flood-related diarrhoea.

Nature’s Pharmacy, Our Treasure Chest: Why We Must Conserve Our Natural Heritage

Medicinal plants grow naturally around us. Over centuries, cultures around the world have learned how to use plants to fight illness and maintain health. These readily available and culturally important traditional medicines form the basis of an accessible and affordable health-care regime and are an important source of livelihood for indigenous and rural populations. Increasingly, medicinal species that reside in natural areas have received scientific and commercial attention. In the United States, of the top 150 prescription drugs, at least 118 are based on natural sources. A child suffering from leukemia in 1960 faced a 10 percent chance of remission; by 1997, the likelihood of remission had been increased to 95 percent thanks to two drugs derived from a wild plant native to Madagascar. But we still know little about the treasure trove inhabiting our wild places. As of 1995, less than 1 percent of all tropical plant species had been screened for potential pharmaceutical applications

Achievements, Gaps, and Emerging Challenges in Controlling Malaria in Ethiopia

Controlling malaria is one of the top health sector priorities in Ethiopia. The concrete prevention, control, and treatment interventions undertaken in the past two decades have substantially reduced the morbidity and mortality attributable to malaria. Emboldened by these past achievements, Ethiopia envisages to eliminate malaria by 2030. Realizing this ambition, however, needs to further strengthen the financial, technical, and institutional capacities to address the current as well as emerging challenges. It particularly needs to step up measures pertaining to diagnosis, domestic resource mobilization, vector surveillance, and seasonal weather forecasting. Read the full article here!
