The length of time that viruses can survive on a surface depends on a number of factors, including the type of virus, the type of surface, and the environmental conditions (such as temperature and humidity).
Generally, some viruses can survive on surfaces for several hours or even days. For example, studies have shown that the COVID-19 virus can survive on surfaces for up to 72 hours, depending on the surface type and other factors. Other viruses, such as the flu virus, can survive on surfaces for up to 24 hours.
It’s worth noting that the risk of infection from a surface is generally lower than the risk of infection from close contact with an infected person or through airborne transmission. However, it’s still important to practice good hygiene and regularly clean and disinfect frequently-touched surfaces to help prevent the spread of viruses.
