There has been a yellow fever outbreak in Angola since December 2015 with over 3,000 cases and over 300 deaths. Because of it nearly 11 million doses of yellow fever vaccine have been given there in emergency vaccine campaigns. The numbers of new cases have declined but it continues to spread. An outbreak is now occurring in neighbouring Democratic Republic of Congo and travellers with yellow fever have gone from Angola to Kenya and China as well. A different yellow fever outbreak is also occurring in Uganda . Because of this yellow fever certificates will probably be checked at borders more strictly than usual so be sure you have your certificate if travelling in such countries in the near future and certainly be vaccinated before you go.
