The U.S. Centers for Disease Control and Prevention (CDC) released a report Tuesday predicting as many as 550,000 to 1.4 million cases of the Ebola virus in Liberia and Sierra Leone alone, by the end of January.
The CDC calculations are based, in part, on assumptions that cases have been dramatically underreported. Other projections haven’t made the same kind of attempt to quantify illnesses that may have been missed in official counts.
CDC scientists conclude there may be as many as 21,000 reported and unreported cases in just those two countries as soon as the end of this month, according to a draft version of the report obtained by The Associated Press.
The agency’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.
Separately, the World Health Organization (WHO) warned in a new report that the number of people infected with the Ebola virus could reach 20,000 by the beginning of November if efforts to contain the outbreak are not accelerated.
