Washington State’s whooping cough outbreak continues to grow. So far this year, there’ve been 397 confirmed cases, compared with 85 last year. Here’s why: for one, whooping cough is cyclical; every 3-4 years, it peaks and then drops down.

Another reason is the vaccine itself, according to a new study by the Centers for Disease Control and Prevention.

Chas Debolt is senior epidemiologist with the state department of health, and co-authored the study. The study looked at the duration of the vaccine’s level of protection, starting from the time a child receives a vaccine.

Public health experts are now recommending that pregnant women get the vaccine for whooping cough during pregnancy. The recommendation is in response to the growing outbreak of the disease in the U.S.

The number of whooping cough cases in Washington State has passed 3,000. Washington’s infection rate was rising so rapidly that health officials called on the Centers for Disease Control and Prevention for help. That was in May. Yesterday, the CDC issued a report on its findings. Scientists noticed an unusual pattern.

The U.S. Centers for Disease Control has sent two epidemiologists to Washington State. The investigators will try to find out what’s causing the state’s rapid rise of whooping cough cases. We get more from Ruby de Luna.

Gov. Chris Gregoire is reaching into emergency funds to help contain the state's whooping cough epidemic.
