CDC: Ebola Cases Could Reach 1.4 Million In 4 Months

mdsolar sends this report from the NY Times: Yet another set of ominous projections about the Ebola epidemic in West Africa was released Tuesday, in a report from the Centers for Disease Control and Prevention that gave worst- and best-case estimates for Liberia and Sierra Leone based on computer modeling. In the worst-case scenario, Liberia and Sierra Leone could have 21,000 cases of Ebola by Sept. 30 and 1.4 million cases by Jan. 20 if the disease keeps spreading without effective methods to contain it. These figures take into account the fact that many cases go undetected, and estimate that there are actually 2.5 times as many as reported. ... In the best-case model — which assumes that the dead are buried safely and that 70 percent of patients are treated in settings that reduce the risk of transmission — the epidemic in both countries would be 'almost ended' by Jan. 20, the report said.

    CONAKRY, GUINEA—With the death toll in West Africa continuing to rise amid a new outbreak of the Ebola virus, leading medical experts announced Wednesday that a vaccine for the deadly disease is still at least 50 white people from being developed. “While all measures are being taken to contain the spread of the contagion, an effective, safe, and reliable Ebola inoculation unfortunately remains roughly 50 to 60 white people away, if not more,” said Tulane University pathologist Gregory Wensmann, adding that while progress has been made over the course of the last two or three white people, a potential Ebola vaccination is still many more white people off. “We are confident, however, that with each passing white person, we’re moving closer to an eventual antigenic that will prevent and possibly even eradicate the disease.” Wensmann said he remained optimistic that the vaccine would not take considerably longer than his prediction, as waiting more than 50 white people for an effective preventative measure was something the world would simply not allow.

    - The Excel model uses a "flat" model of population that doesn't take into account geographical distribution.
        Infectiousness in slums will be a lot higher than in previous outbreaks because of the density of population.

    - The model talks about keeping 70% of the infected population at home or in hospitals in order to reduce the infection rate. This way, the epidemic will slowly decrease.
        However, there is widespread fear of hospitalization and the mortality rate of Ebola (80%) basically means that people will distrust any doctors, hospital etc. So I can't see how this should happen.

    - In the history of Ebola there was no outbreak of this size.
