Can a virus be killed by disinfectant?

Yes, viruses can be killed by disinfectants. Disinfectants are chemicals that are used to kill microorganisms, including viruses, on surfaces. They work by disrupting the structure of the virus or by damaging the virus's genetic material.

Some common disinfectants that are effective against viruses include:

* Alcohol-based hand sanitizers: These sanitizers contain at least 60% alcohol and are effective at killing most viruses, including the flu virus and the common cold virus.

* Bleach (sodium hypochlorite): Bleach is a powerful disinfectant that is effective at killing all types of viruses, including the hepatitis A virus and the HIV virus.

* Quaternary ammonium compounds (quats): Quats are a type of disinfectant that are often used in hospitals and other healthcare settings. They are effective at killing most viruses, including the norovirus and the rotavirus.

It is important to follow the directions on the disinfectant label carefully when using it to kill viruses. Some disinfectants may need to be diluted with water before use, and others may require a specific contact time in order to be effective.

Always test any disinfectant on a small, inconspicuous area of any surface before using it on a larger scale. Some disinfectants can damage certain materials, so it is important to make sure that the disinfectant is compatible with the surface before using it.
