The World Health Organization reported late last month that the ongoing yellow fever outbreak in Africa is serious but that it does not warrant being declared an international health emergency.
Since it was first identified in Angola in December 2015, yellow fever has spread to the Democratic Republic of Congo (DRC) and is believed to have sickened more than 6,300 people and killed about 400, despite millions of doses of vaccine having been sent repeatedly to Angola. In August, some 7.7 million people were vaccinated in a major campaign that was launched in the “high risk” DRC capital Kinshasa, along with 1.5 million in other parts of the country. In Angola, 2.4 million people have been vaccinated, making 11.6 million in all.
The campaigns have depleted the global stockpile of 6 million yellow fever vaccine doses twice this year already, which according to the WHO is unprecedented. The vaccine shortage has now become so acute that officials have begun diluting the vaccine by 80 percent in a bid to stretch the supply. The four major manufacturers who supply the global stockpile have worked around the clock in order to replenish the stockpile.
Last month, the UN health agency convened an emergency committee of experts to consider the outbreak’s status, stating afterwards that the increase of the mosquito-spread haemorrhagic fever appears to have slowed. The WHO further reported that since 12 July there have been no new infections reported in what is an “extremely positive” trend. The upcoming rainy season has raised fears of further spread of the worst outbreak in decades. It also noted that intense population movements across the border to neighbouring Republic of Congo pose a risk of further spread, adding that the Brazzaville government should consider a “pre-emptive vaccination campaign in high-risk areas,” noting that the virus was moving towards Central and Eastern Africa.
