State health officials reported Thursday that California is on track to break a 55-year record for whooping cough infections in an epidemic that has already claimed the lives of nine infants.

At least 4,017 cases of the highly contagious illness have been reported in California, according to the state. Data from the Centers for Disease Prevention and Control show 11,466 cases nationwide, though the federal numbers are known to lag behind local reporting.

Whooping cough is a cyclical illness that peaks in number of infections every five years. Symptoms are similar to the common cold, making it a challenge to diagnose, which in turn makes it difficult for officials to determine if the worst has passed, said Dr. Gil Chavez, an epidemiologist for the California Department of Public Health.

A persistent cough that lasts weeks is the tell-tale symptom of the illness, which is also known as pertussis.

The state is on track to exceed the record 4,949 cases reported in 1955. The bacterial infection tends to peak during summer months, but infections could continue into coming weeks, said Chavez.

"When you have an epidemic, you have more cases circulating in our community" and there is increased opportunity for infection, he added.

The federal numbers for nationwide cases were last updated Sept. 12 and represent 519 more cases than the same period last year, according to the CDC. Other states with high numbers of infections include Texas, where health officials reported 1,783 cases, and Ohio, where federal officials reported 1,019 cases.

In South Carolina, officials reported one whooping cough death and 255 confirmed or suspected cases have been found. Epidemic levels of the illness there were seen earlier this year, but no statewide epidemic was declared.

All of the whooping cough-related deaths in California occurred in babies too young to be fully immunized against the illness, which is why parents and caretakers are being urged to get booster shots. Typically, babies are given a series of vaccinations, then receive booster shots between ages 4 and 6 and again after age 10.

Many parents forgo vaccines for their children because of concerns about autism, typically fueled by misinformation on the Internet, said Dr. Mark Sawyer, a University of California-San Diego professor and fellow of the American Academy of Pediatrics.
