St. Ignatius Prep in San Francisco's Sunset District will now stay closed until Monday. This morning, health officials confirmed norovirus is what's causing more than 300 students and 30 teachers to get sick.

School officials originally planned to re-open the school today, but, changed their mind as the number of people getting sick got bigger. Custodians are using bleach and steam to disinfect the school. Norovirus spreads through the air, or by touch and is highly contagious.

The school's kitchen and water supply have been tested and ruled out as possible sources of contamination.
