From my interpretation of the CDC statement, it doesn't say keeping students at home is ineffective. It states that keeping students at home for less than 8 weeks is ineffective. However, closing schools for 8 weeks or more would help control the spread of the disease.
Nope. The school closure decision tree only starts with a confirmed case in school.
1.
There is a role for school closure in response to school-based cases of COVID-19 for decontamination and contact
tracing (few days of closure), in response to significant absenteeism of staff and students (short to medium
length, i.e. 2-4 weeks of closure), or as part of a larger community mitigation strategy for jurisdictions with
substantial community spread* (medium to long length, i.e. 4-8 weeks or more of closure).
2. Available modeling
data indicate that early, short to medium closures do not impact the epi curve of COVID-19 or available health care measures (e.g., hospitalizations). There may be some impact of much longer closures (8 weeks, 20 weeks) further into community spread, but that modelling also shows that
other mitigation efforts (e.g., handwashing, home isolation) have more impact on both spread of disease and health care measures. In
other countries, those places who closed school (e.g., Hong Kong)
have not had more success in reducing spread
than those that did not (e.g., Singapore).3. In places where school closures are necessary, the anticipated academic and economic impacts and unintended
impacts on disease outcomes must be planned for and mitigated. Provision of academic support (e.g., tele-ed),
alternatives for school-based meals as well as other services (e.g., behavioral and mental health services) for
economically and physically vulnerable children, support for families for whom telework and paid sick leave is not
available, ensuring that high risk individuals continue to be protected must all be addressed. Special consideration
must be given for health care workers so that school closures do not impact their ability to work.
