A member asked:

When i come home and touch doornobs and light switches before washing hands, how long do cold viruses live on those things?

A doctor has provided 1 answer

See details: It depends on the virus. Cold viruses can live on a hard surface for up to 7n days. Flu viruses, however, are only active for 24 hours.
