Health Advisory: Pertussis among high school children, 20 NOV, 2014
Be aware of an increase in pertussis reports among high school children.
Fully immunize all children against pertussis, and provide a single dose of Tdap as recommended by national guidelines to:
Consider pertussis in the following situations (including in immunized patients):
Consider treatment for high risk patients and PEP for high-risk contacts of pertussis cases (see below)
Report pertussis cases to Public Health within 24 hours (206-296-4774)
Background: While county-wide numbers of pertussis cases this season are not higher than expected, a recent cluster of cases among Roosevelt High School students and their contacts (including household members), has been reported (10 confirmed cases reported since the beginning of October). There might be additional cases that were not tested or reported to Public Health. All reported student cases were up to date on their pertussis vaccinations. Health care providers should use droplet precautions (including a surgical mask) when within 3 feet of persons with suspected pertussis during patient encounters. Pertussis testing is available at the Public Health – Seattle & King County Laboratory (206 731-8950) as well as local reference laboratories. A negative pertussis culture or PCR test does not rule-out pertussis when the clinical picture is suggestive. In certain high-risk cases and contacts, initiating treatment after 3 weeks of paroxysmal cough and chemoprophylaxis for contacts should be considered. High-risk cases and contacts include infants aged <1 year and individuals with pertussis or suspected pertussis who may expose persons at high-risk of severe disease (health care workers; labor and delivery, neonatal, pediatric and post-partum staff; pediatricians; midwives, labor coaches, pregnant women; and other persons who may expose an infant).
