Norovirus (Gastroenteritis)

Norovirus is a common yet highly contagious virus that causes viral gastroenteritis outbreaks. It can be spread by an infected person, contaminated food or water, or contaminated surfaces.

People who have norovirus infection are typically sick for 1 – 2 days (though some may not totally recover for several days).


  • Abrupt onset of vomiting
  • Diarrhea
  • Nausea
  • Stomach cramping

Other symptoms include:

  • Fever
  • Body aches
  • Headache


Because norovirus infection is easily transmitted from person to person, we recommend you follow these guidelines to prevent spread:

  • Wash your hands with soap and water, especially after toileting and diaper changing and before eating, preparing, or handling food.
  • If you are sick, do not prepare food for others.
  • After episodes of diarrhea or vomiting, clean contaminated surfaces with a bleach solution (1/3 cup bleach per 1 gallon of water).

Controlling the Spread

Persons who are experiencing symptoms of gastrointestinal illness can be contagious for a few days after they are feeling better. Therefore, students should not attend class and staff should not work until 48 hours after symptoms have stopped.

To reduce further spread of the virus, Bear Creek has implemented a cleaning protocol at school per CDC and Public Health guidelines.

Further information on the norovirus can be found on the CDC and King County Public Health websites.

If you are diagnosed with norovirus or have stomach flu symptoms, please notify the school nurse Lea Hysom at
