Of the 150 countries on the list, the Central African Republic, Tanzania and Burundi rank as the unhappiest countries in the world. Some of the factors driving unhappiness are the poor state of the continent’s health care systems, the persistence of HIV/AIDS, malaria and tuberculosis, and the growth of lifestyle diseases such as hypertension, heart disease and diabetes.Few African countries make...

Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

Conclusion In this review, the ethnomedicinal uses, phytochemistry, biological activities and toxicity of different extracts and compounds of X. caffra have been summarized. Although many of the ethnomedicinal uses of X. caffra have been validated by phytochemical and pharmacological studies, there are still some gaps where current knowledge could be improved. There are very few to nil experimental animal studies, randomized clinical trials and target-organ toxicity studies involving X. caffra and its derivatives that have been carried out so far. At the present moment, there is not sufficient evidence to interpret the spe...

MoreWHO Says Further Investigation Needed on Sexual Transmission of ZikaSee All the Places Where the Zika Virus Has Spread Less than a century since DDT was first sprayed, the spread of the Zika virus through mosquitoes has left some wondering whether regulators were too quick to move away from the chemical. But public health officials warn returning the controversial pesticide to use could do more harm than good in some places. DDT, which first came into use as an insecticide in the 1930s, played a crucial role helping Allied forces protect themselves from mosquitoes carrying malaria in World World II and eventually helpe...
