Yes it is highly contagious:
Noroviruses (the kind that cause stomach flu) are very contagious and can spread easily from person to person. Both stool and vomit are infectious. Particular care should be taken with young children in diapers who may have diarrhea.


How long are people contagious?
People infected with norovirus are contagious from the moment they begin feeling ill to at least 3 days after recovery. Some people may be contagious for as long as 2 weeks after recovery. Therefore, it is particularly important for people to use good hand washing and other hygienic practices after they have recently recovered from a norovirus illness.

Additional note:
The "stomach flu" is also called viral gastroenteritis.
