A new study shows the transmission of COVID-19 is extremely low in K-12 schools providing face-to-face instruction. The study examined eleven school districts in North Carolina. It included nearly 100,000 students and staff and monitored the virus transmission over a nine-week period.
Over 9 weeks, 11 participating school districts had more than 90,000 students and staff attend school in-person; of these, there were 773 community-acquired SARS-CoV-2 infections documented by molecular testing. Through contact tracing, NC health department staff determined an additional 32 infections were acquired within schools. No instances of child-to-adult transmission of SARS-CoV-2 were reported within schools.
Because they looked at both primary and secondary spread, the researchers are confident in their findings.
