Tourism Alert: If planning a trip to the US West Coast, visitors should be aware of am ongoing pertussis epidemic that has escalated in California. State health officials confirmed 4,558 cases reported this year as of Tuesday — 1,100 of those in the last two weeks.

Vaccination of pregnant women is the most important thing that can be done to protect infants.

The health department released a report summarizing the latest data on this year’s epidemic of pertussis, or whooping cough. Of this year’s cases thus far, 3,614, or 84%, have occurred in patients 18 or younger. Out of 142 illnesses that required hospitalization, 89, or 63%, were in infants 4 months or younger.

Three babies have died from pertussis infections in 2014, Chavez said, although two of those will be attributed to 2013’s case count because they initially became ill last year.

Because infants less than a year old are at the highest risk of hospitalization and death from pertussis — and because babies generally do not receive pertussis vaccinations until they are 8 weeks old — Chavez said that all pregnant women should receive the Tdap vaccine during their third trimester.

Whooping cough cases peak on a three- to five-year cycle. Based on historical patterns. it is likely that disease activity will remain high through the summer. But he said it was too soon to know if this year would be worse than 2010, the last year pertussis peaked.

That year, more than 9,000 Californians contracted the disease.
