Because these results suggest a longer duration of protection than previously estimated, they support the continued development of NoV vaccines.

People with stomach flu should drink plenty of liquids such as clear soda, clear broths, or caffeine-free sports drinks. Duration of Immunity to Norovirus Gastroenteritis.

Also, signs of dehydration require a visit to your healthcare provider. However, some older adults, babies, or people with other health conditions can develop complications, such as , that require medical attention and can even lead to death. We are thus assuming that when a susceptible S person becomes infected, disease will later develop and that all first infections are symptomatic.

An incubation period is the period of time between when a person is first infected and when symptoms appear. Norovirus can remain in your feces for a month! Therefore, future modeling studies should address the question of whether severe disease outcomes could best be prevented directly, by vaccinating the elderly, or indirectly, by vaccinating children —. Moreover, population immunity levels may be driven through the acquisition of immunity of fully susceptible persons or through boosting of immunity among those previously exposed. A subsequent study with a shorter challenge interval suggested that immunity to Norwalk virus lasts for at least 6 months.
