How Long Is Vnorovirus Contagious On Surfaces
Several hours: Rsv can survive on hard surfaces such as tables and crib rails for many hours. It also lives on soft surfaces such as tissues and hands for shorter amounts of time. People infected with RSV are usually contagious for 3 to 8 days after the onset of symptoms. Frequent hand washing & meticulous attention to cleaning of surfaces in the room of an RSV infected person can prevent transmission to others. ...Read more
Viruses live longer: ...On hard surfaces like doorknobs, phones & toothbrushes, up to ~48*, than on porous surfaces like fabric or paper, from 20min up to 1d. But in 2008 a study @ univ hospital of geneva showed flu viruses thriving in wet environments. On swiss money, viruses survived ~72* & when mixed w/human mucus, one type a strain remained active for 17d. Clean, clean, clean to kill the virus! ...Read more
Transmissability: The maximum risk of contagion lasts one week after the beginning of symptoms. The recovered person may remain mildly contagious for a couple of weeks after recovery.

Several weeks: This is from the Department of Public Health "When can a person spread the virus to to others? A person may spread the virus to to others just prior to the onset of symptoms, during the acute stage of illness and perhaps longer, since this virus may persist in the stool for several weeks.
