Health Advisory: Serogroup B Meningococcal Disease Outbreak at Oregon State University (OSU) issued November 30, 2017 revised December 1, 2017.

Action requested:

Be aware of an ongoing serogroup B meningococcal disease outbreak at Oregon State University (OSU) in Corvallis. Students from Washington State may return to home during winter break (December 8, 2017 – January 7, 2017). Providers should be alert to the possibility of meningococcal disease among OSU students with compatible symptoms (see below).

Because of the outbreak Snohomish healthcare providers should provide serogroup B meningococcal vaccination to OSU students 25 years of age and younger.

Serogroup B meningococcal vaccine is licensed as either a 2 -dose series (Bexsero® ), with doses administered at least 1 month apart, or as a 3-dose series (Trumenba® ), with doses administered 1-2 and 6 months following the first dose. If Trumenba® is utilized in response to a serogroup B meningococcal disease outbreak, ACIP recommends the 3-dose series in order to provide earlier protection and maximize the immune response. The same vaccine must be used for all doses.

Background: Five OSU students have been diagnosed with serogroup B meningococcal disease during this academic year; the most recent case diagnosed November 24th. Meningococcal disease outbreaks can persist for months. See resources below for information related to the outbreak and meningococcal vaccination.

Symptoms of meningococcal meningitis include Fever, headache, stiff neck, nausea, vomiting, photophobia (eyes being more sensitive to light), and altered mental status (confusion).

Symptoms of meningococcemia include: Fever, fatigue, vomiting, cold hands and feet, chills, myalgia, arthralgia, chest pain, abdominal pain, tachypnea, diarrhea, and, in the later stages, a purpuric rash
