SHOCKING new estimates from the World Health Organisation (WHO) warn the number of Ebola cases could hit 21,000 in six weeks.

The WHO has said the toll will rise relentlessly unless efforts to curb the outbreak are ramped up. The grim analysis was published yesterday by the 'New England Journal of Medicine'.

Since the first cases were reported six months ago, the tally in West Africa has reached an estimated 5,800 recorded illnesses. WHO officials say cases are continuing to increase exponentially and Ebola could sicken people for years to come without better control measures.

But the UN health agency has warned that tallies of recorded cases and deaths are likely to be gross underestimates. For instance, it noted that the true death toll for Liberia, the hardest-hit country in the outbreak, may never be known, since bodies of people dying in a crowded slum in the capital have simply been thrown into rivers.

Spreading

Based partially on the assumption that cases are being under-reported, the US Centres for Disease Control and Prevention is expected to release far higher predictions. A draft version of the report says there could be as many as 21,000 cases in Liberia and Sierra Leone alone by the end of the month and that cases could balloon well past one million by late January.

However, experts caution those predictions don't take into account response efforts.

In recent weeks, health officials worldwide have stepped up efforts to provide aid, but the virus is still spreading.

There aren't enough hospital beds, health workers or even soap and water in the hardest-hit West African countries: Guinea, Sierra Leone and Liberia.

Last week, the US announced it would build more than a dozen medical centres in Liberia and send 3,000 troops to help. Britain and France have also pledged to build treatment centres in Sierra Leone and Guinea and the World Bank and UNICEF have sent more than $1m worth of supplies to the region.

"We're beginning to see some signs in the response that gives us hope this increase in cases won't happen," said Christopher Dye, WHO's director of strategy and co-author of the study published by the 'New England Journal of Medicine', who acknowledged the predictions come with a lot of uncertainties.

"This is a bit like weather forecasting. We can do it a few days in advance, but looking a few weeks or months ahead is very difficult."

They also calculated the death rate to be about 70pc among hospitalised patients but noted many Ebola cases were only identified after they died. So far, about 2,800 deaths have been attributed to Ebola. Dye said there was no proof Ebola was more infectious or deadly than in previous outbreaks.

WHO's numbers seem "somewhat pessimistic" and do not account for infection control efforts already underway, said Dr Richard Wenzel, a Virginia Commonwealth University scientist who formerly led the International Society for Infectious Diseases.

Other outside experts questioned WHO's projections and said Ebola's spread would ultimately be slowed, not only by containment measures but by changes in people's behaviour.

"It's a big assumption that nothing will change in the current outbreak response," said Dr Armand Sprecher, an infectious diseases specialist at Doctors Without Borders.

"Ebola outbreaks usually end when people stop touching the sick," he said.
