Fatal Pediatric Meningococcal Invasive Disease Caused by Neisseria meningitidis Serogroup C and Co-Infected With SARS-CoV-2: Report of a Case in Tijuana, Mexico.

Invasive meningococcal disease (IMD) is a severe infection caused by Neisseria meningitidis, with mortality rates ranging from 10% to 40%. IMD has been confirmed to be an endemic disease in Tijuana, Mexico, right across the border from San Diego, California. To date, coronavirus disease 2019 (COVID-19) is the most severe pandemic, causing more than 5.5 million deaths globally. Prior or co-infections of influenza with IMD has been reported previously; however, the participation of other respiratory viruses facilitating the invasiveness of N. meningitidis is either not shown or remains unclear. Here, we report the case of an unvaccinated (for IMD and COVID-19) seven-year-old child who had confirmed fatal IMD caused by N. meningitidis, serogroup C, and was co-infected by severe acute respiratory syndrome coronavirus 2.
