In Angola, as of 8 July 2016 a total of 3625 suspected cases have been reported, of which 876 are confirmed. The total number of reported deaths is 357, 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 reactive 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.
Other than an increase in the number of suspected cases recently reported, there are no updates regarding the epidemiological situation in the Democratic Republic of The Congo (DRC). For the last three weeks the national laboratory in DRC has been unable to confirm or discard any suspected cases of yellow fever due to technical issues. According to the latest available information (as of 11 July), the total number of notified suspected cases is 1798, with 68 confirmed cases (as of 24 June) and 85 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. Reactive vaccination campaigns will start on 20 July, in Kisenso health zone in Kinshasa province and in Kahemba, Kajiji and Kisandji health zones in Kwango province.
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.
