What diseases can be transmitted through the air?

Diseases that can be transmitted through the air include respiratory infections such as influenza, tuberculosis, and COVID-19. These diseases are spread by respiratory droplets or aerosols released when an infected person coughs, sneezes, or talks. Other airborne diseases include measles and chickenpox, which can linger in the air for extended periods, making them highly contagious. Proper ventilation and protective measures, such as masks, can help reduce the risk of transmission.
