CBS News has learned that the Centers for Disease Control and Prevention is recommending Americans postpone travel to the United States until it can determine whether the virus has reached critical levels.CDC officials have previously said they believe the virus can survive in the air for months before spreading to humans, and that the virus could even survive in soil.
However, the CDC has said that it believes the virus is not spread via direct contact with blood or body fluids.
The CDC has also recommended Americans not wear masks during travel.CDC Director Dr. Thomas Frieden said Wednesday that he thinks the virus poses no immediate threat to the country.
But, he said, the agency is taking a wait-and-see approach.
Frieden added that while the agency has been working with state and local governments to address concerns about potential travel risks, it is not yet clear if the virus will pose any major health risks.
In the meantime, Frieden urged people to continue to wear face masks while outdoors and to take the steps necessary to protect themselves from the virus, including:Avoid close contact with mosquitoes.
Avoid wearing masks in enclosed spaces.
Avoid sitting in public places, including at work, while outdoors.
Limit outdoor activities that involve running, walking or jogging.
If you have been in contact with an infected person, immediately contact local health departments or local health care providers if you have symptoms of the virus.
Stay safe at home, too.
The CDC recommends keeping your doors and windows closed and keeping all windows and doors closed during the virus pandemic.
