SAN DIEGO–San Diego County continues to experience a high level of pertussis (whooping cough) activity, with a nearly six-fold increase in the number of cases to date in 2014 versus this point last year according to the County’s Health and Human Services Agency.

There were 18 new cases reported this week in which others may have been exposed, bringing to 298 the total number of cases reported so far in 2014. There were only 53 cases reported by this date in 2013 and a total of 430 that year. A high of 1,179 cases was reported in 2010. The complete list of new cases is below.

“Pertussis has shown no signs of slowing down and this high level of activity should be a concern for parents and caregivers,” said Wilma Wooten, M.D., M.P.H., County public health officer. “The vaccine’s effectiveness lessens over time so it’s very important that adults get their booster shots and that they make sure their children have the necessary doses of the vaccine at the recommended ages.”

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. Antibiotics can lessen the severity of symptoms and prevent the spread of disease to others.

The Centers for Disease Control and Prevention recommends the following vaccination schedule:

· Young children need five doses of DTaP by kindergarten: at 2 months, 4 months, 6 months, 15 to 18 months and 4 to 6 years.

· All students entering 7th grade need proof of a whooping cough booster immunization (Tdap).

· A Tdap booster is recommended for pregnant women during their third trimester of each pregnancy, even if they got a booster before becoming pregnant.

· One dose of Tdap is recommended for adults 19 years of age and older who did not get Tdap as an adolescent.

Parents can obtain the DTaP vaccine series and the Tdap booster shot for themselves and their children through their primary care physicians. Local retail pharmacies offer vaccinations for a fee, and anyone who is not covered by a medical insurance plan can get the shot from a County Public Health Center at minimal or no cost.
