The World Health Organisation (WHO) said that the number of people with Ebola is set to hit 10,000 in West Africa, The UN's public health body said 9,936 people in Guinea, Liberia and Sierra Leone - the three countries at the epicentre of the world's worst-ever Ebola epidemic - have contracted the disease. In total, 4,877 people have so far died.

With experts warning the rate of infections could reach 10,000 a week by early December, researchers around the world are scrambling to beat the tropical fever, for which there is currently no licensed treatment or vaccine. The figures were released as the WHO in Geneva yesterday held its third round of emergency talks on Ebola, discussing efforts to combat the tropical fever. The talks are expected to last two days.

Meanwhile doses of the experimental rVSV vaccine against Ebola arrived at the Geneva University Hospital from Canada. The WHO is to coordinate trials of the vaccine in Geneva alongside those already under way in Germany, Gabon and Kenya. The vaccine, developed at the National Microbiology Laboratory in Winnipeg, is one of two experimental Ebola vaccines identified by the WHO as having shown promising results when tested on monkeys.

WHO assistant director general Marie-Paule Kieny said the goal was to be able to ship initial supplies to Africa by early 2015, though mass vaccination campaigns are not yet on the cards. There is a very strong movement now from governments of many countries to push as quickly as possible these vaccines into real-world use, she said.

A key aim is to help guard health workers against Ebola - some 240 have died so far as they strive to care for desperate patients. At the same time, the American Institute of Health announced it they had begun a clinical trial of a vaccine trialling it on 39 people. However, even if successful, the vaccine would not be available until next year.

Also yesterday US pharmaceutical giant Johnson and Johnson announced it would spend USD 200 million to accelerate an Ebola vaccine programme that is in development. It plans tests on volunteers in January. The Red Cross said it would be at least four months before the epidemic is contained, but only if all necessary steps are taken.

It will be possible, as it was possible in the past, to contain this epidemic within four to six months if the response is adequate, said Elhadj As Sy, chief of the International Federation of Red Cross and Red Crescent Societies (IFRC).

Interesting facts about the Ebola virus that make it so deadly.

It can kill within seven days: Unlike other viruses (like HIV) that can remain dormant in a person for years without causing the disease, Ebola violently multiplies until the viral particles are amplified to about 100 million viral particles in a droplet of blood. Further, without resting in a dormant stage the virus kills the host to find a new one. The fatality rate of the disease is 60 percent.

There is no vaccine or treatment available: What makes this virus deadly is the fact that researchers have not been able to find an effective treatment or preventive technique to combat the virus and the spread of the disease. The experimental drug Zmapp has shown promising results but the safety and efficacy of the drug are to be evaluated. So, as of now, neither do we have an effective form of therapy nor do we have a vaccine to prevent the disease.

Attacks every part of the human body: Ebola only needs a host cell that can help it produce multiple copies of itself. What worsens the condition is the fact that the virus does not need a specific type of cell to multiply (unlike other deadly diseases). According to studies, except for skeletal muscles and bones, the virus is known to infect every part of the human body. Connective tissues, the ones that hold your internal organs in place, are primary targets of the virus.
