Why it matters

Meningococcal disease is a serious illness that can be life-threatening if not treated promptly. The recent cases in Chicago highlight the importance of vaccination, especially for teenagers and young adults who are at higher risk.

The details

The Chicago Department of Public Health said it has performed contact tracing and provided treatment for close contacts of the confirmed patients. Meningococcal disease is transmitted through direct contact with saliva, usually requiring close and lengthy contact to spread. Symptoms can initially resemble a common illness like a cold or flu, but can rapidly worsen to include a stiff neck, sensitivity to light, cold hands and feet, severe aches, vomiting, diarrhea, and a dark purple rash.

• The Chicago Department of Public Health reported the 7 cases since January 15, 2026.
• The 2 deaths occurred this month.

What’s next

The Chicago Department of Public Health recommends MenACWY vaccination for all patients age 11 or 12, with a booster at age 16, to protect against meningococcal disease.
