At the Ebola treatment center in Foya, Liberia, there's one thought on every American volunteer's mind: 21 days of isolation.
The threat of quarantines for health care workers coming back from West Africa cropped up in nearly every conversation I had on Saturday with doctors and nurses at the clinic run by Doctors Without Borders.
Everyone was worried, especially a nurse from New York City. Some states, like New York, New Jersey and Illinois, are already requiring 21-day quarantines, possibly in hospitals, for all medical staff coming home. Others might follow.
