The deadly Ebola outbreak raging in central Africa probably began several months ago, the World Health Organisation said yesterday, deeming the risk high in the region but low worldwide. “Given the scale, we are thinking that it has started probably a couple of months ago,” Anais Legand, WHO technical officer on viral haemorrhagic fevers, told reporters in Geneva.
Ebola has killed more than 15,000 people in Africa in the past half-century, and the UN health agency declared the latest surge an international health emergency.
The 17th Ebola outbreak to hit the DRC is already suspected of having caused 139 deaths from around 600 probable cases.
“We expect those numbers to keep increasing, given the amount of time the virus was circulating before the outbreak was detected,” WHO chief Tedros Adhanom Ghebreyesus told reporters.
The WHO has highlighted the complexity of detecting and responding to the outbreak, which has been spreading in hard-to-reach areas of the DRC’s conflict-torn Ituri province. Complicating things further, the less common Bundibugyo species behind the outbreak does not show up on tests for the more common Zaire strain of Ebola.
On Sunday, Tedros declared the outbreak a so-called public health emergency of international concern — the second-highest level of alarm under the legally-binding International Health Regulations (IHR), which triggers emergency responses in countries worldwide.
“There are several factors that warrant serious concern about the potential for further spread and further deaths,” he said, adding he “determined that the situation was not a pandemic emergency,” saying the agency “assesses the risk of the epidemic as high at the national and regional levels.
