NEW YORK — If you’ve recently been infected by a virus or have tested positive, you might be able to avoid being infected with a new strain of the virus.

The Centers for Disease Control and Prevention is asking people to test their phones at home.

People who test positive for the coronavirus and their phones will be tested on site at the CDC.

The test will show whether they’re infected with the virus, the agency said.

The CDC is encouraging people to:Avoid touching your phone until you get home, or at least in the middle of the night.

Make sure you don’t have any family members or friends who have tested negative.

If you’re testing positive, check with your doctor or nurse about taking precautions, such as staying home or avoiding public places where you may have been exposed.

If the virus is spreading among people in the U.S., they can also contact a doctor, health care provider, or an emergency room doctor, the CDC said.

Anyone who has been exposed to the virus can be tested for the virus in the CDC’s testing facility, or you can go to a public health clinic and ask to see a health care worker.

People can also visit the CDC website and call 1-800-CDC-INFO for more information.
