Ebola by the Numbers

President Obama announced on Tuesday that up to 3,000 U.S. military personnel will travel to West Africa to help combat the deadly Ebola virus – but this is only the beginning of what may be a long and costly enterprise.

The outbreak in Liberia, Sierra Leone and Guinea of the deadly hemorrhagic fever has now spread to Nigeria and Senegal – and global health experts say they have weeks, not months, to act.

“Everyone realizes that no one group or one country or one organization is going to be able to tackle this,” Dr. Jim Yong Kim, the president of the World Bank and an infectious disease expert, told The New York Times. The U.S. is also sending medicine and equipment.

“We can’t dawdle on this one,” President Obama said Tuesday. Kim said coordination among all involved was an urgent priority.

“Obama’s announcement is an attempt to take the reins in combating the outbreak. The effort, including the influx of personnel to provide medical and logistical support, could cost as much as $750 million over the next six months, senior administration officials said,” reported National Journal. China, Cuba and others are also sending assistance.
