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, the two countries could have a total of 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, the epidemic in both countries would be “almost ended” by Jan. 20, the report said. Success would require conducting safe funerals at which no one touches the bodies, and treating 70 percent of patients in settings that reduce the risk of transmission. The report said the proportion of patients now in such settings was about 18 percent in Liberia and 40 percent in Sierra Leone.
