Yellow Fever outbreak - Angola
On 21 January 2016, the Ministry of Health of Angola has notified WHO of an outbreak of Yellow Fever (YF). The first case with onset date on 5 December 2015 was identified in Viana municipality belonging to Luanda province. As of 07 April 2016, a total of 1,708 suspected cases including 238 deaths (CFR: 13.9%) have been reported from 16 of the 18 provinces.

Cases were reported among Angolan, Cape Verde, Congo, China, DR Congo, Eritrea, India and Kenya nationals living in Luanda.
Although the country has not reported a Yellow Fever outbreak in the last 28 years, large scale outbreaks reported in high density populated areas in Luanda, the capital city of Angola and in main cities in outer provinces are unusual and unexpected. The risk of spread to other provinces and to neighboring countries remains very high. Cases have already been exported to China, Kenya, DR Congo and Mauritania. Other alerts of cross border spread to Zambia and other bordering countries are under investigation. The reports of Yellow Fever imported cases in China, DR Congo, Mauritania and Kenya demonstrate the threat that this outbreak constitutes to the entire world.
WHO does not recommend any restriction of travel and trade to Angola on the basis of the information available on this outbreak. The vaccination of individual before travelling to the affected areas, as well as measures to avoid mosquito bites are essential for the prevention of the disease.
WHO Country Office in Bhutan is providing the needed information to the Ministry of Health. Specifically, considering the presence of Aedes and the frequent travels between South Asia and affected countries it is advisable to ensure that Yellow Fever vaccination card is required and checked on arrival at the airport from endemic countries as a precaution.
