Ebola

WHO says this week has seen the most Ebola cases yet

The World Health Organization said Friday that the past week has seen 500 recorded cases of Ebola, more than any other week thus far.

The increase in Ebola cases proves that the crisis is becoming worse. Most of this week's cases recorded were in Liberia, but the past week also marked record case numbers in Guinea and Sierra Leone.

The news comes a day after the WHO warned that the Ebola outbreak could infect as many as 20,000 people. Ebola has killed more than 1,500 people so far, with 3,000 cases reported.
