Is norovirus killed by bleach?

Norovirus is a highly contagious virus that causes gastroenteritis, an inflammation of the stomach and intestines. This leads to symptoms such as nausea, vomiting, stomach pain, and diarrhea.

When it comes to killing norovirus, bleach-based disinfectants are effective. The reason for this is that norovirus is enclosed by a structure known as a capsid. Bleach is able to get through this capsid and kill the virus, which is why bleach-based disinfectants are recommended for use against norovirus.

Norovirus is resistant to many common disinfectants. However, bleach, including chlorine bleach or hydrogen peroxide, can effectively kill the virus. These substances are able to get through the capsid and kill the virus.

It’s also important to note that norovirus can survive being dried out and can persist on surfaces for several days even at room temperature. Therefore, thorough cleaning of surfaces with a solution of bleach and water is necessary to kill the virus and prevent its spread.

In conclusion, while alcohol-based sanitizers or disinfectants are not effective against norovirus, bleach-based solutions can be used to kill the virus and prevent its spread. This highlights the importance of good hygiene practices and thorough cleaning of surfaces, especially in settings where norovirus outbreaks are common.
