Whooping cough update: outbreak in Montana continues

The Montana Department of Health has reported (pdf) that as of  November 15, 2012, a whooping cough (Bordetella pertussis) outbreak has reached over 500 cases since the beginning of the year, compared to only 129 cases during the same time period in 2011. As of November 15, 33 cases of pertussis were found in infants of less than one year of age. Of these, four have been hospitalized. Because Montana is has a small population (about 1 million people), the overall incidence rate year to date is 50.5 pertussis cases per 100,000 Montana residents. 

This past spring, there was a pertussis outbreak in several Montana counties, but it seemed to abate during the summer. The Department of Health is reporting that Flathead county, a northern county that borders Canada, is currently struggling to contain an outbreak in five school districts. “Since the beginning of October, we have 35 cases,” said Community Health Services Director for Flathead County Jody White. “Usually we won’t even see 35 in a year, so it is definitely unusual to have this many.”

Whooping cough: outbreak in Montana

Add another state in the northwest US, Montana, that is experiencing an outbreak of whooping cough (Bordetella pertussis). Washington and Idaho (where a child has already died), along with nearby British Columbia, have also experienced sizable outbreaks.  

Health officials in Flathead County, Montana, which borders British Columbia, have announced five additional cases of the disease. Some school events were cancelled or postponed since officials were concerned about large gatherings because of the contagiousness of the disease. County health officials are urging parents to make certain that their children have up-to-date vaccinations, and that adults have current vaccinations. The standard vaccine for pertussis is the DTaP, which provides immunity to diphtheria, tetanus and whooping cough.

Vaccines save lives.
