The Centers for Disease Control (hereafter referred to as CDC) today (the 26th) announced the first fatal case of epidemic meningococcal meningitis in 2026, a woman in her 60s from central Taiwan with a history of hypertension. On May 7 she experienced fever, vomiting, diarrhea, dizziness, chills, and generalized weakness. She sought emergency care at a hospital on May 8, developed cyanosis and respiratory failure, and despite emergency treatment she unfortunately died on the same day. Laboratory testing confirmed infection with Neisseria meningitidis serogroup B. Health authorities have identified a total of 20 family members and hospital contacts, all of whom have received prophylactic medication and have been monitored for health status until the end of the observation period on May 18, with no suspected epidemic meningococcal meningitis symptoms.
According to CDC surveillance data, Taiwan has recorded a total of eight confirmed cases of epidemic meningococcal meningitis this year, higher than the number of cases in the same period from 2017 to 2025 (which ranged from 0 to 6). Statistics from the past ten years (starting in 2017) show that the majority of cases occur in the 25–64 age group and those aged 65 and above (each accounting for 29.7%), followed by the 19–24 age group (20.3%), and the 0–6 age group (18.8%). The most common infection is Neisseria meningitidis serogroup B.
The CDC states that the main routes of transmission for epidemic meningococcal meningitis are through contact with the throat or nasal secretions or droplets of infected or carrier individuals, and effective spread requires close (e.g., kissing or coughing) or prolonged contact. Approximately 5%–10% of healthy people may be asymptomatic carriers in the nasopharynx, and only a small number of carriers develop invasive disease. Individuals with weakened immunity are more susceptible. The incubation period is about 2–10 days. Common symptoms include fever, severe headache, neck stiffness, nausea, vomiting, and hemorrhagic rash; sometimes coma and delirium may also occur. In severe cases, it can lead to pneumonia, sepsis, meningitis, or even shock and death, requiring prompt antibiotic treatment. Infants under one year often present atypical and hard-to-detect clinical signs, usually only fever and vomiting, and may also show irritability, crying, difficulty feeding, or bulging fontanelle, but not necessarily the typical neck stiffness of meningitis.
The CDC reminds that to prevent epidemic meningococcal meningitis, one should avoid staying for long periods in crowded or poorly ventilated environments and maintain good hand and respiratory hygiene to reduce the risk of infection; the disease progresses rapidly, and once it occurs, it may deteriorate within a few hours and even cause death, so if suspected symptoms appear, seek medical attention promptly to avoid worsening. The CDC also encourages high‑risk groups for meningococcal infection (including those with persistent complement deficiency, splenic dysfunction, primary immunodeficiency, viral infections, or those living in or traveling to endemic areas) to consider, after physician evaluation, self‑pay vaccination with the serogroup B meningococcal vaccine or the quadrivalent conjugate meningococcal vaccine.
