Whooping cough outbreak in California grows

The number of whooping cough cases in California continues to grow as San Diego county has reported three new cases this week, raising the total number of infections in the state so far this year to 3,311 cases.

In addition to the reported infections, there have been eight infant deaths caused by whooping cough this year, reports.

The San Diego County Health and Human Services Agency reports that San Diego County has had 412 whooping cough cases reported so far this year. The three latest cases were for a three- and five-year-old who were both up-to-date on immunizations and a 10-year-old who was due for a booster shot, county officials told

The previous record for whooping cough cases in San Diego County, set in 2005, was 371.

CDC officials recommend that children, who are the most vulnerable to whooping cough, receive combination vaccine shots for whooping cough, diphtheria and tetanus, known as Tdap, at two, four and six months of age, at 15 to 18 months and at four to six years of age.

Health officials have also encouraged parents to get their newborn children born before leaving the hospital. A booster shot, health officials say, should be given if one hasn't been administered in the last five to 10 years.
