With COVID-19 infection rates rising across the country, school officials across the United States are scrambling to find ways to reopen schools. Some schools have said they will offer a mix of face-to-face and virtual learning in the fall, while some school districts have announced they will not offer face-to-face learning when school starts. In addition, many parents and teachers worry about the risks and limitations of going back to school.
Health experts advise parents to wear masks for their children because the main transmission route of the virus is person-to-person transmission, especially in crowded places and indoors. So kids need to keep a safe physical distance. In addition, schools should also strengthen hygiene and cleanliness.
There are several ways that can efficiently reduce the infection rate, includes: conduct outdoor teaching, eat lunch in the classroom and improve the school’s air ventilation and filtration equipment.
Reducing the possibility of airborne transmission of the virus and improving air filtration and ventilation in schools are essential.
The simplest method is to increase the inflow of outdoor air by opening windows and using a fan. In addition, schools that already use mechanical ventilation systems should upgrade existing filters. Moreover, using portable air purifiers in classrooms is a feasible way to improve indoor air quality.
In addition, the American Academy of Pediatrics recommends that the physical distance between students be reduced from the standard 6 feet to 3 feet with a mask on. Experts say another effective strategy is to divide children into different classes. And social distancing should be maintained between employees to protect the health of teachers and staff.
