FAIRFAX, Va. (CBSDC/AP) — A Fairfax County school has been scrubbed with bleach after the suspected outbreak of a virus affecting dozens of students and staff.

Authorities say about 100 students and staff members at Willow Springs Elementary in Fairfax, Virginia were reported sick on Friday with a stomach illness. The illness continued to keep dozens of them home on Monday. All weekend activities at the school were canceled to allow for cleaning.

The county health department has been investigating whether it was an outbreak of Norovirus. Medical experts say it can take two days to recover and a third day before a person with the virus is no longer contagious.

Health officials say this is the peak time of year for the illness. Symptoms include vomiting, diarrhea, stomach pain, chills and fatigue. The Center For Disease Control says one of the easier ways to become infected is by having direct contact with a person who is already infected.
