The best available evidence indicates if children become infected, they are far less likely to suffer severe symptoms.[1],[2],[3] Death rates among school-aged children are much lower than among adults.

At the same time, the harms attributed to closed schools on the social, emotional, and behavioral health, economic well-being, and academic achievement of children, in both the short- and long-term, are well-known and significant.

Further, the lack of in-person educational options disproportionately harms low-income and minority children and those living with disabilities.

These students are far less likely to have access to private instruction and care and far more likely to rely on key school-supported resources like food programs, special education services, counseling, and after-school programs to meet basic developmental needs.

The best available evidence indicates that COVID-19 poses relatively low risks to school-aged children.

To put this in perspective, according to the CDC, as of July 17, 2020, the United States reported that children and adolescents under 18 years old account for under 7 percent of COVID-19 cases and less than 0.1 percent of COVID-19-related deaths.[5]

Although relatively rare, flu-related deaths in children occur every year. From 2004-2005 to 2018-2019, flu-related deaths in children reported to CDC during regular flu seasons ranged from 37 to 187 deaths. During the H1N1 pandemic, 358 pediatric deaths were reported to CDC.

So far in this pandemic, deaths of children are less than in each of the last five flu seasons, with only 64.† Additionally, some children with certain underlying medical conditions, however, are at increased risk of severe illness from COVID-19.*

Scientific studies suggest that COVID-19 transmission among children in schools may be low. International studies that have assessed how readily COVID-19 spreads in schools also reveal low rates of transmission when community transmission is low.

Based on current data, the rate of infection among younger school children, and from students to teachers, has been low, especially if proper precautions are followed.

There have also been few reports of children being the primary source of COVID-19 transmission among family members.

This is consistent with data from both virus and antibody testing, suggesting that children are not the primary drivers of COVID-19 spread in schools or in the community.

***No studies are conclusive, but the available evidence provides reason to believe that in-person schooling is in the best interest of students, particularly in the context of appropriate mitigation measures similar to those implemented at essential workplaces.***

Extended school closure is harmful to children.

t can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.

Following the wave of school closures in March 2020 due to COVID-19, academic learning slowed for most children and stopped for some.

A survey of 477 school districts by the University of Washington’s Center on Reinventing Public Education found that, “far too many schools are leaving learning to chance.”[13]

Just one in three school districts expected teachers to provide instruction, track student engagement, or monitor academic progress for all students, and wealthy school districts were twice as likely to have such expectations compared to low-income districts.[13]

The prospect of losing several months of schooling, compared to the few weeks of summer vacation, due to school closure likely only makes the learning loss even more severe.

Disparities in educational outcomes caused by school closures are a particular concern for low-income and minority students and students with disabilities.

A study by researchers at Brown and Harvard Universities assessed how 800,000 students used Zearn, an online math program, both before and after schools closed in March 2020.[15]

Data showed that through late April, student progress in math decreased by about half, with the negative impact more pronounced in low-income zip codes.[15]

Persistent achievement gaps that already existed before COVID-19, such as disparities across income levels and races, can worsen and cause serious, hard-to-repair damage to children’s education outcomes.[15],[16]

Finally, remote learning makes absorbing information more difficult for students with disabilities, developmental delays, or other cognitive disabilities.

In particular, students who are deaf, hard of hearing, have low vision, are blind, or have other learning disorders (e.g., attention deficit hyperactivity disorder (ADHD)) and other physical and mental disabilities have had significant difficulties with remote learning.[17]

Extended school closures are harmful to children’s development of social and emotional skills. Important social interactions that facilitate the development of critical social and emotional skills are greatly curtailed or limited when students are not physically in school.

Additionally, extended closures can be harmful to children’s mental health and can increase the likelihood that children engage in unhealthy behaviors.

An environment where students feel safe and connected, such as a school, is associated with lower levels of depression, thoughts about suicide, social anxiety, and sexual activity, as well as higher levels of self-esteem and more adaptive use of free time [19],[20]

A longitudinal study of 476 adolescents over 3 years starting in the 6th grade found school connectedness to be especially protective for those who had lower connectedness in other areas of their lives, such as home, and to reduce their likelihood of substance use.[20]

Further, a review of studies conducted on pandemics found a strong association between length of quarantine and Post Traumatic Stress Disorder symptoms, avoidance behavior, and anger.

Another review published this year found that post-traumatic stress scores of children and parents in quarantine were four times higher than those not quarantined.[21],[22]

For children with intellectual or physical disabilities, nearly all therapies and services are received through schools. These vital services are difficult to provide through distance learning models.

As a result, more children with disabilities have received few to no services while schools have been closed.

Extended school closures deprive children who live in unsafe homes and neighborhoods of an important layer of protection from neglect as well as physical, sexual, and emotional maltreatment and abuse.

A 2018 Department of Health and Human Services report found that teachers and other educational staff were responsible for more than one-fifth of all reported child abuse cases—more than any other category of reporter.

During the COVID-19 school closures, however, there has been a sharp decline in reports of suspected maltreatment, but tragically a notable increase in evidence of abuse when children are seen for services.

For example, the Washington, D.C. Child and Family Services Agency recorded a 62 percent decrease in child abuse reporting calls between mid-March and April 2020 compared to the same time period in 2019, but saw more severe presentation of child abuse cases in emergency rooms.

Extended school closures can be harmful to the nutritional health of children.

Schools are essential to meeting the nutritional needs of children with many consuming up to half their daily calories at school.

Nationwide more than 30 million children participate in the National School Lunch Program and nearly 15 million participate in the School Breakfast Program. For children from low-income families, school meals are an especially critical source of affordable, healthy foods.

While schools have implemented strategies to continue meal services throughout periods of school closures, it is difficult to maintain this type of school nutrition program over the long-term.

This is a particularly severe problem for the estimated 11 million food-insecure children, living in the United States.

When schools are closed, children lose access to important opportunities for physical activity. Many children may not be sufficiently physically active outside of the context of in-school physical education (PE) and other school-based activities.

Current models estimate that childhood obesity rate may increase by 2.4 percent if school closures continue to December 2020.[

To summarize, CDC confirms what I've been saying: anti-schoolers and anti-children and anti-science. https://www.cdc.gov/coronavirus/2019-ncov/community/schools-childcare/reopening-schools.html#footnote2
