CDC REPORT: young children do contract SARS-CoV-2 and spread it to their households. Study of three Salt Lake City childcare facilities uncovered 12 children who acquired the virus and passed it onto 26% of their non-facility contacts, including family members

2. These included symptomatic and asymptomatic transmission. "Having SARS-CoV-2 testing available, timely results, and testing of contacts of persons with COVID-19 in child care settings regardless of symptoms can help prevent transmission" https://www.cdc.gov/mmwr/volumes/69/wr/mm6937e3.htm?s_cid=mm6937e3_w

3. While the @CDCgov web guidance for child care programs recommends the use of face masks, hand hygiene, & frequent cleaning and disinfecting, it unfortunately isn't emphasizing the importance of ventilation as it should be doing. https://www.cdc.gov/coronavirus/2019-ncov/community/schools-childcare/guidance-for-childcare.html
