Schools are an environment conducive to the spread of COVID-19. They are densely occupied for long periods. In fact, schools are where children spend the most time, other than home--often 30-40 hours per week. Like adults, children may shed and transmit the coronavirus, yet show no symptoms. Except for masks, there is no personal protection equipment (PPE) for children, who breathe more air per pound of body weight than adults; further, children cannot identify or protect themselves from risks. Schools can either slow the spread of the virus or speed it up. If they are to reduce, rather than increase, the risk of new COVID-19 outbreaks and repeated closures, schools will need to adopt districtwide, facility-level written school infection prevention and control plans to address the details of cleaning, disinfecting, sanitation, indoor air, and environmental quality, as well as occupancy rates, occupant behaviors, and how to determine day to day who can enter. COVID-19 is a public health crisis. This report is the national call to action for the public health community--the states and tribes and big city public agencies--to produce guidance, in the form of an authoritative Plan for Infection Prevention and Control in Schools that local schools can adopt as they prepare for reopening. These authoritative state-level plans offered to schools should include detailed recommendations on specific steps that schools should follow and selected options for other issues.
