A few months ago the U.S. Centers for Disease Control and Prevention predicted that up to 1.4 million people in Liberia and Sierra Leone could become infected with Ebola by mid-January. In a recent address to the Senate, CDC director Tom Frieden said that worst-case scenario would not pan out.

That is partly because health care workers in the Ebola hot zone are engaged in a battle to contain the epidemic. It is also because of assumptions about human and viral behavior that are built into the mathematical models used to predict the spread of infectious diseases. Assumptions are inherent in these models. “You take islands of data from different places and build bridges of assumptions that link up all these islands,” says Martin Meltzer, senior health economist at the CDC. Meltzer’s model, which predicted the 1.4 million infections in Liberia and Sierra Leone, worked on the assumption that things would not improve. “Our forecasts are based on the idea that nothing will change,” he says.

CHICAGO -- The U.S. Department of Health and Human Services on Tuesday offered liability protections to drugmakers rushing to develop Ebola vaccines and urged other countries to follow suit.

Health and Human Services (HHS) Secretary Sylvia Burwell made the announcement as part of the Public Readiness and Emergency Preparedness (PREP) Act in a move aimed at encouraging the development and availability of experimental Ebola vaccines.

The declaration provides immunity under U.S. law against legal claims related to the manufacturing, testing, development, distribution, and administration of three vaccines for the Ebola virus. However, it does not provide immunity for a claim brought in a court outside the United States...

THE GUARDIAN     by Sarah Bosley                                                                           Dec. 9, 2014                          FREETOWN --  Sierra Leone has its first-ever call centre. The number to reach it is 117. You can call to report that your mother is sick or your brother is dead. It is a call nobody wants to make, but posters and newspapers and radio broadcasts urge you to pick up the phone – for your own sake and your family’s, but beyond that, for the sake of everybody else you know and don’t know.

It’s a tough one, because that call leads to quarantined homes and holding centres for people with suspected Ebola, where people who do have the virus are sharing rooms with those who eventually turn out to have something else. There’s a real possibility you could go in with malaria and pick up Ebola. It is in the public interest that you make that call. But it is hardly surprising if some people hesitate and others run and hide

(Reuters) - More foreign health workers are needed to help tackle the Ebola epidemic, which is spreading quickly in western Sierra Leone and deep in the forested interior of Guinea, a senior U.N. official said on Tuesday.

The death toll from the Ebola outbreak in West Africa has risen to 6,331 in the three worst hit countries, with Sierra Leone overtaking Liberia as the country with the highest number of cases, the World Health Organization says.

"We know the outbreak is still flaming strongly in western Sierra Leone and some parts of the interior of Guinea. We can't rest, we have to still push on," said David Nabarro, the U.N. Special Envoy on Ebola.
