A 15-year-old who was up-to-date on immunizations and attends Helix Charter High School is among five newly reported cases of pertussis found at schools throughout San Diego County this week, according to the San Diego County Health and Human Services Agency.
Also known as whooping cough, cases were also confirmed in Lincoln Acres, La Costa Canyon and Chula Vista.
A typical case of pertussis starts with a cough and runny nose for one to two weeks, followed by weeks to months of rapid coughing fits that sometimes end with a whooping sound. Fever, if present, is usually mild. The disease is treatable with antibiotics, according to the County News Center.
