All teachers should wear face shields. Schools must provide these as well as upgrade ventilation and filters BEFORE students return to school. The Fed Govt must provide already financially broke disticts the money and supplies.
"Aerosol transmission does increase the importance of one additional protective step, which is proper ventilation and air filtration. Airflow, either introducing new air into a room or filtering the existing air, can disperse and dilute any infectious aerosol particles, reducing a person’s potential exposure. Being outdoors is the ultimate ventilation, and for months public health officials have recommended that people socialize outside rather than in. However, with winter and colder temperatures coming, indoor air filtration and adherence to masks will become even more important."
"Armed with this knowledge, think about how you can make fall and winter safer, both physically and mentally. Instead of buying another can of Lysol, maybe invest in an air purifier, more comfortable two-ply cloth masks, or even an outdoor fire pit or space heater. Be prepared to meet friends outside in colder temperatures or insist upon masks, even in your home. We’ve still got a long way to go before we can declare victory over the novel coronavirus, but at least we know more now than we did six months ago. And you don’t have to sanitize your apples anymore."
