Abstract

In January–February 2025, a community outbreak of serogroup B was reported in Aragón, Spain, with nine confirmed cases. This represents a 27-fold increase vs the previous 3 years. Five cases had respiratory co-infections; seven were attributed to complex CC213. Epidemiological investigations revealed a potential link to a school setting, though direct transmission could not be confirmed. These findings highlight the need to reinforce surveillance during periods of high respiratory virus circulation and in outbreaks involving non-4CMenB-covered variants.
