Johannesburg, Mar 24: The World Health Organization says the first yellow fever outbreak in Angola in decades has killed 178 people.
The organization said today that more than 450 people have been infected by the disease since the outbreak was first reported in December last year.
The WHO statement said that while 5.7 million people have been vaccinated against yellow fever, there is a global vaccine shortage.
Half of the severely infected patients die within 10 to 14 days if they do not receive treatment.
Yellow fever is spread by mosquitoes, most commonly the Aedes aegypti mosquito, the same species that spreads the Zika virus.
