The World Health Organization (WHO) has declared the spread of Ebola in West Africa an international health emergency.

According to the BBC, WHO officials said a coordinated international response was essential to stop and reverse the spread of the virus.

The announcement came after experts convened a two-day emergency meeting in Switzerland.

So far more than 930 people have died from Ebola in West Africa this year.

WHO says the outbreak is an “extraordinary event”.
