Invasive Meningococcal X Disease during the COVID-19 Pandemic, Brazil

Abstract

Invasive meningococcal disease persists as a fulminant disorder worldwide. Although cases caused by Neisseria meningitidis serogroup X (MenX) occur infrequently, outbreaks have been reported in countries in Africa in recent decades. We report 2 cases of MenX invasive meningococcal disease in São Paulo, Brazil, in 2021 and 2022, during the COVID-19 pandemic.
