DHAKA: More than 1,900 people have now died in West Africa’s Ebola outbreak, the World Health Organization (WHO) says.

There have been 3,500 confirmed or probable cases in Guinea, Sierra Leone and Liberia.

‘The outbreaks are racing ahead of the control efforts in these countries,’ WHO chief Margaret Chan said.

The WHO is meeting on Thursday to examine the most promising treatments and to discuss how to fast-track testing and production.

Disease control experts, medical researchers, officials from affected countries, and specialists in medical ethics will all be represented at the meeting in Geneva.

At least $600m are needed to fight the virus, and more than 20,000 people could be infected before the outbreak is brought under control, the WHO has warned.

Chan described the outbreak as ‘the largest and most severe and most complex we have ever seen’, reports the BBC.
