Bacteria and germs can transmit through the air, which can lead to the spread of airborne diseases. When an infected person breathes, coughs or sneezes, small respiratory droplets that carry harmful bacteria and germs will be generated and linger in the air for hours. When inhaled by another person, these airborne particles can cause infections and make people sick.

Moreover, bacteria and germs that are in the air will gradually land and settle, causing nearby objects and surfaces to be contaminated as well. Anyone who touches the surfaces can also spread the virus and cause severe infections.
