The US Centers for Disease Control and Prevention should be doing more to guide and encourage improved air circulation in buildings -- especially in schools -- to help prevent the spread of coronavirus, ventilation experts say.
They say the CDC has not paid anywhere near enough attention to the role ventilation can play in helping the spread of coronavirus -- or reducing it.
Schools will need to spend time and money improving airflow using HVAC systems, stand-alone HEPA air filtering systems or even just by opening windows if students, teachers and staff are to return safely to in-school learning in the fall, the experts say.
