Situation Report Yellow Fever, 8 July 2016
In Angola, as of 1 July 2016 a total of 3552 suspected cases have been reported, of which 875 are confirmed. The total number of reported deaths is 355, of which 117 were reported among confirmed cases. Suspected cases have been reported in all 18 provinces and confirmed cases have been reported in 16 of 18 provinces and 80 of 125 reporting districts.
Mass vaccination campaigns first began in Luanda and have now expanded to cover most of the other affected parts of Angola. Recently, the campaigns have focused on border areas. Despite extensive vaccination efforts circulation of the virus persists.
Eleven reactive and pre-emptive mass vaccination campaigns are ongoing in several districts in Benguela, Huambo, Huila, Kwanza Norte, Kwanza Sul, Lunda Norte and Uige provinces. Six other mass vaccination campaigns are nearing completion. Mop-up campaigns are being implemented in parts of the provinces of Cunene, Lunda Norte, Uige and Zaire.
There are no updates regarding the epidemiological situation in the Democratic Republic of The Congo (DRC). According to the latest available information (as of 24 June), the total number of notified suspected cases is 1307, with 68 confirmed cases and 75 reported deaths. Cases have been reported in 22 health zones in five of 26 provinces. Of the 68 confirmed cases, 59 were imported from Angola, two are sylvatic (not related to the outbreak) and seven are autochthonous.
In DRC, surveillance efforts have increased and vaccination campaigns have centred on affected health zones in Kinshasa and Kongo Central.
Two additional countries have reported confirmed yellow fever cases imported from Angola: Kenya (two cases) and People’s Republic of China (11 cases). These cases highlight the risk of international spread through non-immunised travellers.
Seven countries (Brazil, Chad, Colombia, Ghana, Guinea, 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 convened on 19 May 2016, the 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.
