Ugandans have been warned to prepare for El-Nino such as this one.

The El Niño phenomenon that started last year poses a health threat to at least 60 million people in seven high-risk developing countries including Uganda.

According to the World Health Organisation (WHO), other countries that will be affected include Ethiopia, Lesotho, Kenya, Papua New Guinea, Somalia and Tanzania, whose collective financial request for support has reached US$76 million.

As a result, the WHO and its partners predict a major global increase in health consequences of emergencies this year due to El Niño.

“From Ethiopia to Haiti to Papua New Guinea, we are seeing the damage from El Niño, and we believe the impact on public health is likely to continue throughout 2016, even after El Niño winds down,” said Dr Richard Brennan, Director of WHO’s Emergency Risk Management and Humanitarian Response Department, in a press release.

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. 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.

Meanwhile, the WHO expects more countries will seek financial support to respond to El Niño effectively. Part of the response will be to provide additional health services to those in need, such as increased surveillance and emergency vaccination.
