WHO Warns Again Over Africa Escalation

The World Health Organization has warned that Africa might be headed for a much larger outbreak than current numbers are suggesting.

"I am very concerned right now that we are beginning to see an acceleration of disease in Africa," WHO's emergencies chief Michael Ryan said.

So far, the continent has managed to avoid becoming a hotspot with around 15,000 deaths and 725,000 confirmed infections.

But a surge in South Africa - the continent's worst-hit country - could be seen as a warning for what might happen to the rest of Africa. There are more than 370,000 cases and 5,000 deaths in the country.

"This isn't just a wake-up call for South Africa," Ryan said. "We need to take what is happening in Africa very, very seriously."
