Ebola could infect 1.4 million by end of January, CDC says


The number of Ebola cases in West Africa could reach 1.4 million by the end of January if trends continue without an immediate and massive scale-up in response, according to a new estimate by the Centers for Disease Control and Prevention.

Researchers say the total number of cases is vastly underreported by a factor of 2.5 in Sierra Leone and Liberia, two of the three hardest-hit countries.

Reported cases in those two countries are doubling approximately every 20 days, researchers said.
