Why did viruses like flu and RSV reemerge after the #COVID19 pandemic? A recent study from our #InfectiousDisease experts led by principal investigator @kmess44.bsky.social reveals insights about viruses, our immune system and how to prepare for the future: prn.to/4lztth8

Thanks Jess! I have no idea what I am doing on here... even less so than Twitter. I'd love to follow more #IDSky so please follow/reach out if you are interested in #pedsID #diagnosticstewardship #enterovirus #EVD68 #EVA71 #acuteflaccidmyelitis #encephalitis #meningitis #pandemicpreparedness

Yes the infection pause or immune gap is measurable.

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.

Immunologic study shows rebound of other viruses after COVID measures lifted

The authors showed how a relatively small serosurveillance scheme could complement traditional surveillance, enhancing epidemic understanding and forecast modeling.
