What is the infection control measure recommended during an outbreak of norovirus?

The recommended infection control measure during an outbreak of norovirus focuses on the use of strict hand hygiene and environmental cleaning. Norovirus is highly contagious and can be transmitted through contaminated surfaces, food, and direct contact with infected individuals. Hand hygiene, especially thorough handwashing with soap and water, is crucial, as alcohol-based hand sanitizers may not be effective against norovirus.

Additionally, environmental cleaning is essential because the virus can survive on surfaces for extended periods. Regular disinfection of frequently touched surfaces helps reduce the risk of spreading the virus within the community or healthcare settings. This dual approach—ensuring proper hand hygiene and maintaining clean environments—forms a robust strategy to control and prevent further transmission during an outbreak.

Other options, such as antiviral medications and routine vaccinations, are not standard practices for norovirus management. There are currently no specific antiviral treatments for norovirus, and while isolation of infected individuals can help prevent the spread, it is insufficient without rigorous hygiene practices. Vaccinations for norovirus are not widely available at this time, making strict hand hygiene and environmental cleaning the most effective measures during an outbreak.
