Summary

This study looked at how many children of hospital workers had antibodies against the virus that causes COVID-19. Researchers tested blood and saliva samples from 563 family members to see if a parent's infection status affected the child's risk. The goal was to better understand how the virus spreads within families, especially when parents are exposed at work.
