EbolaRICHMOND, Va. (AP) _ Virginia health officials are now actively monitoring all travelers arriving in the state from the three West African countries affected by the Ebola outbreak. Secretary of Health and Human Resources Bill Hazel and state Health Commissioner Marissa Levine announced the enhanced precautions Monday. Airport screeners are providing contact information for travelers from Guinea, Liberia and Sierra Leone. Those travelers are assessed for Ebola risks and are asked to sign an agreement to take their temperature at least twice a day. Low-risk travelers receive daily phone calls from health care workers, while those at higher risk receive personal visits and are told to stay home. Health care workers returning from West Africa are required to restrict activity based on their risk level.  So far, 53 travelers have been identified for monitoring.
