Increase nationwide

On March 28, 2024, CDC (Centers for Disease Control and Prevention) issued a health advisory about the increase in invasive serogroup Y meningococcal disease in the United States. Washington has not seen an increase in cases. Washington had 4 confirmed cases of meningococcal disease in 2023. Providers have reported 3 confirmed cases so far in 2024.

Recommendations for healthcare providers

Invasive meningococcal disease can affect anyone. Current increases disproportionately affect people who are 30–60 years old, Black or African American, and living with HIV.

  • Keep an eye out for invasive meningococcal disease—If you suspect a patient has meningococcal disease, start antibiotic treatment, and get blood and CSF (cerebrospinal fluid) cultures.
  • Be aware—Patients with invasive meningococcal disease may have bloodstream infection or septic arthritis, without typical meningitis symptoms (e.g., headache, stiff neck).
  • Notify—Immediately call (509) 249-6541 to notify the Health Department of suspected or confirmed cases of invasive meningococcal disease.
