CDC and Health Canada update guidelines emphasizing airborne spread
Both the CDC and Health Canada now have guidelines for preventing infectious aerosols from accumulating in the air, emphasizing airborne spread of COVID-19 indoors. “Staying home with only members of your household is the best way to keep SARS-CoV-2 particles out of your home. However, if a visitor needs to be in your home, improving ventilation (air flow) can help prevent virus particles from accumulating in the air in your home.”
