A: Since the outbreak erupted, the CDC has sent about two dozen staffers in West Africa to help try to track cases, set up emergency response operations and provide other help to control the outbreak. Last week, CDC officials said the agency will send 50 more in the next month. CDC workers in Africa also are helping to screen passengers at airports, according to CDC director Dr. Tom Frieden.
Q: Is the U.S. government doing anything extra for arriving passengers?
A: Border patrol agents at Washington's Dulles International Airport and New York's John F. Kennedy International Airport, in particular, are looking out for travelers who might have been exposed to the virus. They're watching for signs of fever, achiness, sore throat, stomach pain, rash or red eyes. The CDC also has staff at 20 U.S. airports and border crossings evaluating travelers with signs of dangerous infectious diseases and isolating them when necessary.
