when you are contagious

Viral gastroenteritis can be caused by several different viruses. The two most common are:

  • Norovirus: This is the most common cause of stomach flu. Symptoms develop one to three days after exposure, and once you develop symptoms, you can be contagious.
  • Rotavirus: This virus is contagious even before symptoms appear and for two weeks after recovery. Usually, symptoms begin to appear one to two days after exposure.

Patients with viral gastroenteritis are advised to resume daily activities after being asymptomatic for 24 hours. Even so, you can still be contagious three days after recovering and can spread the infection for up to two weeks.

For both viruses, children can spread the infection longer than adults.
