Using the latest data from the US Census Bureau's Current Population Survey to measure the childcare needs of health-care workers if schools are shut, researchers estimate that nationwide, at least one in seven medical workers may have to miss work to care for their children aged 3-12 years old, even after taking into account childcare provided by non-working adults and older siblings within the same household.

These additional childcare obligations could compromise the ability of the US healthcare system to respond to COVID-19 if alternative childcare arrangements are not made, researchers say.
