Climate change and human health in the Eastern Mediterranean and Middle East: Literature review, research priorities and policy suggestions.

Human health is linked to climatic factors in complex ways, and climate change can have profound direct and indirect impacts on the health status of any given region. Susceptibility to climate change is modulated by biological, ecological and socio-political factors such as age, gender, geographic location, socio-economic status, occupation, health status and housing conditions, among other. In the Eastern Mediterranean and Middle East (EMME), climatic factors known to affect human health include extreme heat, water shortages and air pollution.

Temporal trend of diarrhea morbidity rate with climate change: Egypt as a case study.

Many studies have detected a relationship between diarrhea morbidity rates with the changes in precipitation, temperature, floods, droughts, water shortage, etc. But, most of the authors were cautious in their studies, because of the lack of empirical climate-health data and there were large uncertainties in the future projections. The study aimed to refine the link between the morbidity rates of diarrhea in some Egyptian governorates representative of the three Egyptian geographical divisions with the meteorological changes that occurred in the 2006-2016 period for which the medical data are available, as a case study.

Responding to Emerging Diseases Requires Multi-disciplinary and One Health Training, Egypt.

Background: In Egypt, several infectious diseases of zoonotic origin have emerged in recent years like H1N1, MERSCoV and H5N1, the latter now endemic. Responding to these diseases requires a workforce trained in multi-disciplinary approaches to zoonotic disease research and control. It is difficult to deliver multidisciplinary and one health training globally because of the limited number of higher education programs that support such training.
