How Does Inhalation Contribute to Disease Transmission?
Many respiratory diseases are spread through inhalation of aerosols or droplets containing infectious agents. For instance, illnesses such as influenza, tuberculosis, and COVID-19 are primarily transmitted via inhalation of droplets expelled when an infected person coughs, sneezes, or talks. Inhalation can also be a mode of exposure to environmental toxins, such as air pollutants and asbestos.
