What is the recommended action to prevent the spread of norovirus in the workplace?

Excluding staff with norovirus symptoms is the most effective action to prevent the spread of this virus in the workplace. Norovirus is highly contagious and can easily be transmitted through direct contact with an infected person, contaminated surfaces, or food prepared by someone who is ill. By ensuring that individuals exhibiting symptoms such as vomiting, diarrhea, or stomach cramps do not work, you significantly reduce the risk of spreading the virus to other employees and customers.

This measure not only protects the health of the staff but also ensures that food safety standards are maintained. In environments where food is prepared, the risks associated with norovirus are particularly high, making it essential to take proactive steps to exclude anyone who may be contagious. This approach acts as a first line of defense in managing an outbreak and promoting a safer workplace.

While the other options may offer some protective measures, they do not address the core issue of controlling the introduction of the virus into the environment as effectively as excluding symptomatic individuals does.
