GENEVA, September 05, /ITAR-TASS/. The Ebola virus killed 2,105 people in west Africa and 3,967 are infected, the World Health Organisation (WHO) said on Friday.

Liberia tops the list of the countries with the highest death toll, with 1,089 deaths from the deadly virus, which is resistant to any existing drugs and vaccines known to date.

Liberia remains the most vulnerable country, where 200 cases have been registered every week over the past three weeks, the WHO said.

The virus is spreading fast in the provinces of Lofa and Montserrado and is threatening the capital Monrovia with the population of one million people.

Sierra Leone registers 150 new Ebola cases every week.

The WHO response plan aimed at counteracting this virus disease envisages that it will take from six to nine months to curb the outbreak while well over 20,000 people might be infected for this period of time.
