How many days after noroviru symptoms, should my husband sleep in a separate bedroom/ use a separate bathroom? When can we be together (cuddle, kiss)?

Take precautions: The Center for Disease Control's website suggests waiting at least 2 days after symptoms resolve before having contact with others (such as preparing or sharing food) where exposure and transmission can take place.

Norovirus is going around my house and I have some Zofran (ondansetron) left over. If I feel symptoms coming on can I take the Zofran (ondansetron) as a preventative measure?

Norovirus is going around my house and I have some Zofran (ondansetron) left over. If I feel symptoms coming on can I take the Zofran (ondansetron) as a preventative measure?

Zofran (ondansetron) for norovirus: Norovirus is a nasty virus that causes "stomach flu". It is highly infectious, that's why you'll see it on the news when everyone on the cruise ship gets sick. If the illness is going around your household, you may get it too unless you're extremely careful with hygiene (hand washing). Alcohol based hand rubs aren't 100% for norovirus. Zofran (ondansetron) will help with nausea/vomiting if really needed. ...Read more
