Just like primary schools, we found limited #sarscov2 infection or transmission when UK secondary schools reopened fully from Sep-Dec 2020

We measured #COVID19 antibodies in blood, which captured symptomatic & asymptomatic infections in students & staff

Between Sep & Dec 2020, 8.7% (57/652) staff & 6.6% (36/549) students seroconverted (antibody -ve ➡️ +ve) (p=0.16)

At the end of term, antibody positivity rates were similar in staff & students, & comparable to local community antibody positivity rates

This is yet another study showing that schools are not filled with asymptomatic kids spreading #SARSCoV2 to others. If that was the case, antibody positivity rates would be much higher (esp. in kids) as seen in care homes, hospitals, prisons, etc (30-60%)
