On Sunday, the World Health Organization (WHO) declared an Ebola outbreak in the Democratic Republic of the Congo and Uganda to be a public health emergency. This outbreak is deadly, with hundreds of cases across at least two countries, including, by report, one American who was working in the area.
At the same time, a cluster of hantavirus cases linked to a Dutch cruise ship in the South Atlantic has killed three and exposed hundreds more.
Outbreaks such as these are why the U.S. cannot let down our defenses against microbes — and why programs such as PEPFAR, the President’s Emergency Plan for AIDS Relief, matter so much.
