We usually hear about the highly-contagious norovirus when it strikes a cruise ship. But it kept some 50 students home from school in Marin County Friday.
The Larkspur-Corte Madera School District confirmed flu-like symptoms in students Friday.
Custodians, staff, and volunteer parents disinfected classrooms Friday before students arrived at Neil Cummins Elementary School in Corte Madera
According to district superintendent Valerie Pitts, the students affected belonged to two classrooms which are teamed together. Of the 50 students teamed together, about half fell ill Thursday afternoon. None of the students in the teamed classtooms came to school on Friday as a precaution, Pitts said.
Pitts said that the health office is fully staffed to monitor the rest of the student population.
"We've been in touch with the health department, they're very supportive," Pitts said.
Health officials asked parents to carefully evaluate their children Monday morning and to keep them home if they don't feel well.
