For a safe school operation, healthy and virus-free air in the classroom is needed to avoid infections and diseases. Viruses, such as COVID-19, can spread through the air in the form of aerosols. Depending on factors including ventilation rates and particulate levels, these viruses can remain airborne for several hours. Indoor environments can experience a higher concentration of aerosols (high viral load), which can increase the risk of infection.
During the winter we experience fresh and clear air thanks to the cold but what most people don’t understand is that the air quality changes. The cold climate contributes not only to dry hands, electric hair, and parched mucous membranes, many people experience cold flu, and other sicknesses during the winter. Why and is there anything we can do to counteract it?
