The World Medical Association (WMA) has expressed concern about the possible spread of yellow fever epidemic, including a shortage of the yellow fever vaccine.
Angola, in Africa, is currently in the midst of a yellow fever outbreak since December 2015, reported to be the worst in three decades. It has infected more than 2,000 people, with cases also reported in the Democratic Republic of Congo, Kenya and China. The yellow fever virus is spread by the Aedes aegypti mosquito, which also transmits the Zika virus, dengue and chikungunya. Symptoms of yellow fever infection range from a self-limiting febrile illness to severe liver disease and organ failure.
On 19th May, the WHO had convened an Emergency Committee (EC) in view of the outbreak of yellow fever in Angola in Africa, where it was decided that the urban yellow fever outbreaks in Angola and the Democratic Republic of the Congo are a serious public health event, which warrants intensified national action and enhanced international support.
