My husband got the norovirus and was sick on the 24 Istayed away from him and I havent been sick yet but how long would it take for me to show symptom?

You're probably ok. The average incubation period of Norovirus is no longer than 48 hours, meaning that if you were infected, you would show symptoms within 48 hours of being infected or coming into contact with the virus. Maintain good hand hygiene.
