A Brooklyn high school being used as a shelter for Sandy victims has to be shut down and sanitized after about a dozen storm refugees came down with a stomach virus.
Mayor Bloomberg said John Jay High School will be closed Wednesday instead of opening for classes as scheduled.
"The school will be thoroughly cleaned and then reopened," Bloomberg said.
The mayor said none of the sickened storm victims was severely ill. The cleaning is being done as a precaution, he said.
Thousands of city residents from low-lying areas stayed in shelters as Sandy smashed the tri-state.
Bloomberg also said 10 schools that suffered storm damage or lost power will open Wednesday. The majority of city schools reopened on Monday.
Another 47 schools still won't be open Wednesday. Bloomberg said parents should check www.nyc.gov to see where those students will need to report.
