In San Francisco, city health officials say students not vaccinated for the whooping cough could be prohibited from going to school for at least three weeks -- if there's an outbreak.

They say there were some classrooms where 40 percent of students were not vaccinated last year. Fifty cases have already been reported in the city this year.

The school district will send out letters to parents encouraging to get their children immunized.

Whooping cough starts out like a common cold and is a highly contagious respiratory tract infection.
