Given the fact that you offered no factual refutation but simply a meme with you howling we all know you are full of shit.
The reason the transmission rates in schools are so low is because of mask wearing, social distancing and increased santizing and cleaning protocols. With teachers and children in buildings in close proximity these masures have kept the spread via school contact down very significantly.
FACT:
Studies of SARS-CoV-2 transmission in schools that consistently implemented layered prevention strategies have shown success in limiting transmission in schools, even when testing of close contacts has been incomplete.38, 46, 49, 73-77 For example:
- A study of 11 school districts in North Carolina with in-person learning for at least nine weeks during the fall 2020 semester reported minimal school-related transmission even while community transmission was high.38 These schools implemented and strictly adhered to multiple prevention strategies, including universal mask use and physical distancing. Breaches in mask use likely explained the few instances of in-school spread of SARS-CoV-2.
- A study of elementary schools in Utah who implemented layered prevention strategies, such as mask wearing and cohorting, found very low transmission (secondary attack rate 0.7%) in December 2020-January 2021.74
- In a study of K-12 schools in St. Louis with multiple layered prevention strategies in place, only 2% of contacts of COVID-19 cases in the schools tested positive for the virus; this was despite high community transmission rates.76
- A study of Italian schools, which implemented a comprehensive prevention approach that included masking, distancing, cleaning, increased ventilation, and cancellation of extracurricular activities, found that school reopening was not associated with the second wave of COVID-19 in Italy.47
- A surveillance study of symptomatic and asymptomatic cases among children in Swiss schools found limited secondary transmission when multiple protective measures were used in schools,56 including mask use, physical distancing, and other interventions.
- Data from surveillance of German school outbreaks detected outbreaks before any prevention strategies were implemented. After schools reopened with prevention strategies in place, the average number of outbreaks per week after the reopening (2.2) was smaller than before the school closed earlier in the pandemic (3.3), suggesting that prevention strategies had some protective effect.51
- A study of private schools that reopened for in-person instruction in Chicago with the implementation of layered prevention strategies found minimal in-school transmission.57
When a combination of effective prevention strategies is implemented and strictly adhered to in the K-12 in-person learning environment, the risk of transmission in the school setting appears to be lower than or equivalent to the transmission risk in other community settings.47, 103
