How does airborne transmission occur?

Airborne transmission occurs primarily through the suspension of droplets or dust in the air. This method of transmission allows pathogens to remain in the air and be inhaled by individuals who may be at a distance from the source of the infection. When an infected person coughs, sneezes, talks, or breathes, tiny respiratory droplets may be emitted into the air. These droplets can remain suspended and potentially travel long distances, posing a risk of infection to others who inhale them.

This mode of transmission is especially significant for certain infections, such as tuberculosis or the viruses that cause measles and chickenpox. Understanding airborne transmission is critical in healthcare settings, particularly in nursing homes, where vulnerable populations may be at higher risk for severe complications from respiratory infections. Measures such as proper ventilation, use of masks, and isolating infected individuals are important strategies to control airborne diseases and protect residents' health.
