How do we know that masking helps prevent spread among unvaccinated people in schools? In July 2020, we and our colleagues developed the ABC Science Collaborative to pair scientists with school and community leaders to make sure that school leaders had the most up-to-date, scientific information pertaining to Covid-19 and K-12 schools. In conjunction with North Carolina, the ABC Science Collaborative collected data from more than one million students and staff members in the state’s schools from March to June 2021. Certain school districts in North Carolina were required, by bipartisan legislation, to submit infection data to the ABC Science Collaborative as a trusted third party.
During that time, more than 7,000 children and adults acquired the coronavirus and attended school while infectious. Because of close contact with those cases, more than 40,000 people required quarantine. Through contact tracing and testing, however, we found only 363 additional children and adults acquired the coronavirus. We believe this low rate of transmission occurred because of the mask-on-mask school environment: Both the infected person and the close contact wore masks. Schools provided this protection without expensive screening tests for the coronavirus or massive overhauls in ventilation systems.
Because North Carolina had a mask mandate for all K-12 schools, we could not compare masked schools to unmasked schools. To understand the preventive impact masks can have, we looked outside North Carolina for comparisons. Data from our research and from studies conducted in Utah, Missouri and Wisconsinshows that school transmission rates of coronavirus were low when schools enforced mask mandates. By contrast, one school in Israel without a mask mandate or proper social distancing protocols reported an outbreak of Covid-19 involving 153 students and 25 staff members.
from the report - not the study - I can’t find a link to the study, only the report.
Proper masking is the most effective mitigation strategy to prevent secondary transmission in schools when COVID-19 is circulating and when vaccination is unavailable, or there is insufficient uptake.
Plan A – full in-person instruction – is appropriate for all grades, all schools, when masking is in place. There is not a medical reason to provide Plan B or fully remote instruction if masking is provided
Full-capacity bus transportation appropriate, with up to three masked students per bus seat
Current quarantine guidelines have resulted in more than 40,000 students and staff being quarantined. Thus, over 100 people were quarantined for every within-school infection. Due to the low transmission rate (an estimated secondary attack rate of 1%), and in order to promote in-person education, the State should consider eliminating quarantine for those appropriately masked or vaccinated.
The author of the study says very clearly how they determined masking was effective in schools and it included comparing data to unmasked schools.
The question is whether any of the immigrants that Biden flew into Florida were carrying the new variant that is responsible for the current outbreak. The power of exponential growth means that one case can become millions in a short period of time.
Over 10 million unvaccinated. 150-200k a week are Covid positive. Even if I grant you that 20000 Covid infected illegals were dumped in Florida this week. That is a 10% increase.
