“Bacterial meningitis can progress quickly, causing the brain to swell and limbs to develop gangrene and sepsis, and can kill within 24 hours… “It’s even more important now that we get meningococcal vaccines out to people given that we are seeing a spike in this Y strain,” Messacar said.”

Dynamics of endemic virus re-emergence in children in the USA following the COVID-19 pandemic (2022–23): a prospective, multicentre, longitudinal, immunoepidemiological surveillance study
In this study, we captured immunological evidence of endemic virus re-emergence in children following lifting of pandemic NPIs, which revealed high rates of exposure to endemic respiratory pathogens in a large group of seronegative, predominantly younger, children. This study demonstrates the feasibility and utility of immunoepidemiological surveillance to enable more precise and accurate modelling of pathogen circulation dynamics to predict and prepare for future waves of disease.
