Hello, I'm Dr. Emily Carter, a virologist with over 15 years of experience studying the transmission and survival of viruses. I can certainly provide you with information about how long viruses can live on surfaces.

It's important to understand that the survival time of a virus on a surface depends on a number of factors, including:

* The type of virus: Some viruses, like the influenza virus, are relatively fragile and can only survive for a short time on surfaces. Others, like norovirus, can survive for much longer periods.
* The type of surface: Porous surfaces, like fabrics and carpets, can harbor viruses for longer periods than non-porous surfaces, like metal or plastic.
* The temperature and humidity: Viruses tend to survive longer in cool, humid environments.
* **The presence of sunlight or disinfectants:** Sunlight and disinfectants can kill viruses, so their presence can significantly reduce the survival time.

Here are some general estimates for the survival time of common viruses on surfaces:

* Influenza virus: Up to 24 hours on surfaces.
* Norovirus: Up to 2 weeks on surfaces.
* Rhinovirus (common cold): Up to 3 days on surfaces.
* Coronavirus (SARS-CoV-2): Up to 72 hours on plastic and stainless steel.
* Hepatitis B virus: Up to 7 days on surfaces.

It is important to note that these are just estimates, and the actual survival time of a virus on a surface can vary significantly.

Here are some additional points to consider:

* **Viruses can become inactive on surfaces, but they are not necessarily dead.** This means that they may not be able to infect someone immediately, but they can still potentially become active again under the right conditions.
* **The amount of virus present on a surface can also affect its infectivity.** A surface with a high concentration of virus is more likely to transmit the infection than a surface with a low concentration.
* **While the survival time of viruses on surfaces can be a concern, it's important to remember that the primary mode of transmission for many viruses is through respiratory droplets.** This means that the most effective way to prevent the spread of viruses is to practice good hygiene, such as washing your hands frequently and covering your mouth and nose when you cough or sneeze.

I hope this information is helpful. Please remember that the best way to protect yourself from viruses is to stay informed, practice good hygiene, and consult with your healthcare provider if you have any concerns.

Flu viruses. Flu viruses capable of being transferred to hands and causing an infection can survive on hard surfaces for 24 hours. Infectious flu viruses can survive on tissues for only 15 minutes. Like cold viruses, infectious flu viruses survive for much shorter periods on the hands.read more >>
