What might cause recurring upper respiratory infections, sinusitis, rhinitis, and bronchitis in a classroom?
Most upper respiratory infections are spread through the person-to-person route of direct contact with respiratory droplets or the discharge from the infected individual’s nose or throat. Improvements in ventilation, particularly the introduction of more outside air, may dilute infectious organisms and respiratory droplets that may be circulating in the air.
