What germs are spread by breathing?

Germs spread by breathing primarily include respiratory viruses and bacteria, such as influenza virus, respiratory syncytial virus (RSV), and the bacteria that cause tuberculosis and pneumonia. These pathogens can be transmitted through respiratory droplets when an infected person coughs, sneezes, or talks. Additionally, some germs can linger in the air as aerosols, increasing the risk of airborne transmission in crowded or poorly ventilated spaces. Proper hygiene and ventilation are essential in reducing the spread of these germs.
