Two Die in Chicago Meningococcal Cluster, Health Officials Warn
Two people in Chicago have died in a cluster of meningococcal infections (Neisseria meningitidis), with seven cases reported since Jan. 15; Chicago typically sees 10-15 such infections in winter. The disease spreads through saliva and requires close, lengthy contact, and symptoms can resemble a common illness before worsening rapidly. Officials urge immediate medical care if symptoms appear (stiff neck, sensitivity to light, severe aches, vomiting, or a dark rash). Illinois recommends MenACWY vaccination at ages 11-12 with a booster at 16.
