    Pertussis Outbreak

    Waukesha County and the State of Wisconsin experienced a large outbreak of pertussis in 2012. In 2012, there were 477 cases of pertussis in Waukesha County and in 2013 there were 80 cases, as compared to an average of 27 cases in a non-outbreak year.

    How can pertussis be prevented?

    Vaccines to prevent pertussis are available for infants, children, adolescents and adults. The vaccine for adolescents and adults is 70% effective according to the CDC and remains the best way to prevent the disease. It is effective in preventing severe illness and hospitalizations.

    How is pertussis controlled in schools?

    Students and staff who are diagnosed with pertussis are isolated and do not attend school until no longer infectious (after 5 days of appropriate antibiotic). Notifications are sent to parents to increase awareness of symptoms and promote early diagnosis. Closing schools is not necessary and is not the standard approach for the control of pertussis.
