Yellow fever transmission persists in some West African countries

Six months since the outbreak of yellow fever began in Luanda, Angola, the transmission of yellow fever virus continues. The infection has spread rapidly in Angola with almost 3,000 cases and 328 deaths reported by 33 districts in 11 provinces, including Luanda. There may be transmission in all of Angola's provinces.

The outbreak was spread by Angolan travellers to the Democratic Republic of the Congo where local transmission of this virus has been reported in Ndjili and Kimbanseke districts, in Matadi (Kongo Central) and in Kwango province, respectively.

Advice For Travellers

There is international concern that the situation could worsen in the near future. The virus is spreading in densely populated areas and there is a potential shortage of vaccine for containing it. China and Kenya have reported cases in unvaccinated travellers returning from Angola, and neighbouring countries such as Zambia and Namibia are at risk for introduction of the virus by travellers.

Travellers should not travel to countries where there is a risk of exposure to yellow fever without being vaccinated at least 10 days prior to departure.
