26 April 2016, Geneva - As efforts to bring an outbreak of yellow fever in Angola under control continue, WHO is reminding all travellers to the country that they are required to receive the yellow fever vaccination and to have a valid certificate of vaccination to prove that they are protected from the disease and to prevent its further spread.

Since the outbreak in Angola began in December 2015, 1975 suspected cases of yellow fever (618 laboratory confirmed) and 258 deaths have been reported, the majority of them in the capital, Luanda, and in two other provinces. Amid concerns that the virus will spread to other urban areas and to neighbouring countries, a large-scale vaccination campaign was launched in February 2016 and has so far reached almost 7 million people.
