Situation Report Yellow Fever, 16 June 2016
In Angola the total number of notified cases has increased since early 2016. As of 15 June a total of 3137 cases have been reported, of which 847 are confirmed (Table 1). The total number of reported deaths is 345, of which 112 deaths reported among confirmed cases. Suspected cases have been reported in all provinces, and confirmed cases have been reported in 16 of 18 provinces and 78 of 121 reporting districts (Table 2).
Mass vaccination campaigns first began in Luanda and have now expanded to cover most of the other affected parts of the country, recently the campaigns have focused on border areas. Despite extensive vaccination efforts circulation of the virus persists.
As of 15 June 2016, 1044 suspected (71 deaths) and 61 laboratory confirmed cases (Table 1) have been reported in 22 health zones in the Democratic Republic of The Congo (DRC) (Table 2). Of these 61 confirmed cases: 53 were imported from Angola, two are sylvatic and six are autochthonous cases
Surveillance efforts have increased and vaccination campaigns in DRC have centred on affected zones in Kinshasa and Kongo Central.
Three countries already have reported confirmed yellow fever cases imported from Angola: DRC (53 cases), Kenya (two cases) and People’s Republic of China (11 cases). This highlights the risk of international spread through non-immunised travellers.
Seven countries (Brazil, Chad, Colombia, Ethiopia, Ghana, Peru and Uganda) are currently reporting yellow fever outbreaks or sporadic cases not linked to the Angolan outbreak.
Following the advice of the Emergency Committee (EC) convened on 19 May 2016, WHO Director-General decided that urban yellow fever outbreaks in Angola and DRC are serious public health events which warrant intensified national action and enhanced international support. The events do not at this time constitute a Public Health Emergency of International Concern (PHEIC).
