"Airborne" is a term that refers to something that is in the air or being transported through the air. This can include anything from airplanes to airborne diseases. When we think of airborne, we often picture planes flying high above the ground, carrying passengers or cargo to different destinations. In the context of health, "airborne" can describe how certain illnesses, like the flu or COVID-19, spread through tiny droplets in the air. When an infected person coughs or sneezes, these droplets can travel and infect others nearby. Understanding airborne transmission is crucial for preventing the spread of diseases.
