My husband had the 24 hour norovirus yesterday. The only contact I had was hugging him and he breathed in my face. Could I get sick? Will Zofran (ondansetron) help?

Viral Illness. Zofran (ondansetron) is not a preventative medication. It does not treat viral illness or prevent a viral illness. It is an anti-nausea medication. You husband was most contagious the day before he was ill and slightly less contagious the day he was ill. If you do not have symptoms then I am not sure why you are worrying.
