Wood R, Thomson E, Galbraith R, et al. - Due to a range of potential mechanisms, a relative protection from COVID-19 has been seen in children. Researchers examined if contact with children is associated with gaining a degree of protection from COVID-19 among adults.

• Based on linked administrative data, researchers conducted a cohort study of 241,266, 41,198, 23,783 and 3,850 adults who shared a household with 0, 1, 2 and 3 or more young children, respectively.

• An attenuated risk of any COVID-19 and COVID-19 requiring hospitalization was recorded among adults living in healthcare worker households in correlation with living with young children.

• Living with young children did not appear to be linked with an increased risk of COVID-19 among adults, even during the period after schools reopened.
