Overview
- National surveillance shows higher case counts than recent years, with the latest bulletin logging 255 cumulative meningitis and meningoencephalitis cases versus a five‑year average of 234, while some media cite 172 because they counted fewer weeks.
- Authorities say the pattern remains within expected bounds and is under close monitoring across provinces.
- Doctors warn that falling vaccine coverage increases the risk of severe illness and call for families to complete the schedule for Hib, pneumococcal, and quadrivalent meningococcal shots, with MenB available privately and free for some high‑risk patients.
- Expanded PCR testing is identifying the germs behind more cases, reducing the share once recorded as unknown even when antibiotics have been started.
- Most reported patients are children and adolescents, infants under five face the highest risk, and provinces report mixed local pictures such as Mendoza’s steady yearly totals and Santa Fe’s recent uptick in notifications, so parents are urged to seek urgent care for high fever, neck stiffness, or confusion.
