MINNEAPOLIS (AP) — Minnesota health officials say they're currently monitoring 48 recently arrived travelers as part of their new program to watch for signs of Ebola.

The Department of Health says it's contacting another 12 travelers to set up monitoring.

The monitoring doesn't mean the travelers have any symptoms of the disease. It's part of the screening protocols the state recently announced.

The travelers recently arrived in Minnesota from Liberia, Sierra Leone or Guinea. They'll be watched for 21 days for fever or any symptoms of possible infection. That's the incubation period for the disease that has wracked those western African nations.
