ST. PAUL, Minn. (AP) - Minnesota health officials say they'll be in daily touch with travelers returning to Minnesota from Liberia, Sierra Leone and Guinea for 21 days, the incubation period for Ebola.

Public health nurses or epidemiologists will call the travelers to quiz them about any symptoms and to record their temperatures, which they are supposed to take twice a day.

Minnesota health officials say they are prepared to start the checks next week if the U.S. Centers for Disease Control approves.

About 10 people arrive each week from the West African nations. Minnesota has one of the largest Liberian communities in the U.S.

The checks are part of a larger program unveiled Wednesday by the CDC that starts Monday for travelers arriving in New York, New Jersey, Maryland, Virginia, Pennsylvania and Georgia.
