CDC guidance emphasizes cleaning shared surfaces and fresh air after a cold
After someone recovers from a cold, basic precautions at home can still help limit the spread of respiratory germs.
The guidance involves the U.S. Centers for Disease Control and Prevention and the World Health Organization, which recommend handwashing, cleaning frequently touched surfaces and bringing in fresh air.
Shared items and surfaces may include door handles, light switches, taps, phones and remote controls.
Washing hands with soap and water for at least 20 seconds helps remove germs.
Regular cleaning with soap or detergent removes dirt and many germs, while disinfection uses products intended to kill most germs.
Daily disinfection may not be needed if surfaces are cleaned carefully after use, but it may be considered when someone at home is ill or more vulnerable to illness.
Closed, crowded spaces with little ventilation can make respiratory infections spread more easily, so opening windows and spending time outdoors when possible can improve airflow.
These are routine prevention steps; the guidance does not call for disinfecting every room.
After a cold, basic household precautions can help limit the spread of respiratory illnesses, even when symptoms have improved.
The US Centers for Disease Control and Prevention recommends handwashing, regular cleaning of frequently touched surfaces and measures to improve indoor air.
Frequently touched items may include countertops, railings, doorknobs, light switches, taps, remote controls and phones.
The CDC says routine disinfection may not be necessary when surfaces and objects are cleaned carefully after use, but it may be considered when someone in the home is sick or especially vulnerable.
The World Health Organization says ventilation can help reduce the concentration of potentially infectious aerosols, but it does not replace other prevention measures.
