Mass. travelers could be forced to cancel flights due to Ebola virus

Travelers traveling to or from Liberia and Sierra Leone should brace for a travel advisory due to the outbreak of the Ebola virus.

The advisory was issued Tuesday, saying travelers from the three countries could be required to stay home for a week if they are sick with the disease, according to a statement from the Department of Homeland Security.

Those who have not had contact with a person who is infected can continue to travel, according the statement.

Anyone who has not been vaccinated against the virus can continue.

People with any medical conditions should not travel to or enter the U.S. or its territories.

The travel advisory is voluntary, but those who need it should contact their health care provider, the statement said.
