Association between living with children and outcomes from covid-19: OpenSAFELY cohort study of 12 million adults in England
https://www.bmj.com/content/372/bmj.n628
"Conclusions In contrast to wave 1, evidence existed of increased risk of reported SARS-CoV-2 infection and covid-19 outcomes among adults living with children during wave 2. However, this did not translate into a materially increased risk of covid-19 mortality, and absolute increases in risk were small."
"Living with children aged 0-11 was associated with reduced risk of death from both covid-19 and non-covid-19 causes in both waves;"
