TUCSON, Ariz. (AP) - Pima County health officials have declared a second outbreak of whooping cough in the Vail School District southeast of Tucson and health officials are banning unvaccinated children at one school for at least two weeks.
The 10,000-student district says students who get vaccinated against the highly contagious disease can come back in two weeks. But those still without their shots may not be allowed back in school for three weeks or more.
The Arizona Daily Star reports five students at Sycamore Elementary School recently contracted the disease. The Vail district has had 18 confirmed cases this year.
Whooping cough is also called pertussis and is highly contagious. It typically isn't life-threatening for teens and healthy adults, but it can kill infants and people with weak immune systems.
