Duration of stomach flu depends on the severity of the attack. The condition may become worse in case of infants, young children and elderly who cannot drink sufficient fluids to compensate for dehydration experienced during the illness. For these people, stomach flu can last for 3 weeks or more.
How long can stomach flu viruses live in my house (norovirus and others)? Answer: The stomach flu viruses can live on surfaces for about 2 weeks. Once everyone in your house is done being sick, it is reasonable to assume that you will have stray viruses lingering on household surfaces for another 2 weeks. Norovirus has been shown to live on kitchen counter tops for at least 7 days1.
