ECDC has published Epidemiological update: Outbreak of yellow fever in Angola. Excerpt:
An outbreak of yellow fever that started in December 2015 in the municipality of Viana, Luanda province, has been spreading to other provinces of Angola in the past weeks. A rapid increase in the number of suspected cases was recorded since mid-January 2016.
As of 8 May 2016, the Angolan Ministry of Health has reported 2 267 cases and 293 deaths. Of those, 696 cases are confirmed. Of the confirmed cases, 445 are from Luanda and 251 are from outside of Luanda. Confirmed cases have been reported in 14 of Angola 18 provinces. This week, Namibe province (south of Angola, bordering Namibia) was reported as affected.
Yellow fever cases in people who travelled from Angola have been reported in China (11 cases), Democratic Republic of the Congo (37 confirmed cases), Kenya (two cases), Mauritania (one case) and Namibia (one case).
More than seven million people in Luanda have been vaccinated through a large-scale vaccination campaign since the beginning of February, using vaccines mobilised through the yellow fever vaccine emergency stockpile made available through the International Coordinating Group for Vaccine Provision, with support from Gavi, the UN Central Emergency Response Fund, and a vaccine donation from Brazil.
On 5 May 2016, the Ministry of Health of the Democratic Republic of the Congo (DRC) issued an update on the yellow fever outbreak. Since the beginning of January 2016 and as of 4 May 2016, DRC has reported five probable cases and 39 laboratory-confirmed cases: 37 imported from Angola, reported in Kongo central province and Kinshasa, and two autochthonous cases in Ndjili, Kinshasa and Matadi, Kongo Central province. The possibility of locally acquired infections is under investigation for at least 10 non-classified cases in Kinshasa and Kongo Central provinces.
A response plan, involving the Ministry of Health, WHO and non-governmental organisations has been developed. It includes a vaccination campaign in eight health zones, the six districts of Kongo Central and at least two districts in Kinshasa.
On 29 April 2016, media quoting the Ministry of Health in Namibia reported one confirmed case of yellow fever. In addition, media sources last week reported a suspected case of yellow fever at the Engela district hospital in the Ohangwena region. The patient had travelled to Lubango in Angola and was transferred to the Oshakati Hospital and later discharged.
In Uganda, on 5 May 2016, WHO issued an update on the yellow fever outbreak in Uganda, which is unrelated to the outbreak in Angola. Between 26 March and 18 April 2016, health authorities reported 41 yellow fever cases, including seven deaths. Among them, seven cases and two deaths were laboratory-confirmed. The 41 cases are reported in the districts of Masaka, Rukungiri, Ntungamo, Bukumansimbi, Kalungu, Lyantonde, and Rakai. None of the cases had a recent travel history to Angola.
WHO estimates that 508 million people are living in 31 African countries at risk for transmission of yellow fever. Therefore, the large outbreak of yellow fever in Angola is of concern with regard to the risk of introduction of the virus through viraemic travellers to countries at risk of transmission, especially in neighbouring countries.
In DRC, the confirmation of the autochthonous circulation in the capital is a major concern as Kinshasa is highly populated, representing a risk of extension to Brazzaville, the capital of the Republic of the Congo, that is located across the Congo river.
Meanwhile, WHO has published a Q & A on yellow fever in Angola.
