Global report on El Nino and health
The World Health Organization (WHO) and its partners predict a major global increase in health consequences of emergencies this year due to El Niño. El Niño is a warming of the central to eastern tropical Pacific Ocean which affects rainfall patterns and temperatures in many parts of the world but most intensely in the tropical regions of Africa, Asia-Pacific, and Latin America which are particularly vulnerable to natural hazards. Typically, some places receive much more rain than normal while others receive much less. According to a new report by WHO, severe drought, flooding, heavy rains and temperature rises are all known effects of El Niño that can lead to food insecurity and malnutrition, disease outbreaks, acute water shortages, and disruption of health services. The health implications are usually more intense in developing countries with fewer capacities to reduce the health consequences. The current El Niño from 2015 to 2016 is predicted to be the worst in recent years, and comparable to the El Niño in 1997-1998 which had major health consequences worldwide. In Eastern Africa, as a result of the El Niño in 1997-1998, WHO found that rainfall patterns were unusually heavy and led to serious flooding and major outbreaks of malaria, cholera and Rift Valley Fever.
