[Epidemiological characteristics and analysis of onset-to-diagnosis and diagnosis-to-report time intervals for meningococcal meningitis in Zhejiang Province from 2014 to 2024].

From 2014 to 2024, the incidence of meningococcal meningitis in Zhejiang Province remains low. In the general population, serogroup B is the predominant strain, with co-circulation of multiple serogroups including Y, C, and W. The 0-4-year-old group has a relatively higher incidence, with serogroup B being the predominant strain in this age group. In the future, more efforts should be devoted to strengthen the sensitivity of monitoring for meningitis and improve the ability of medical institutions to differentiate and diagnose atypical symptoms of meningitis.
