Which condition is associated with airborne transmission?

Airborne transmission refers to the spread of pathogens through droplets that remain suspended in the air over long distances and times. Chickenpox is caused by the varicella-zoster virus, which is known to be transmitted via airborne routes. When an infected person coughs or sneezes, the virus can linger in the air and be inhaled by individuals who are not immune, leading to infection.

In contrast, while influenza, strep throat, and pertussis (whooping cough) can also be spread through respiratory droplets, they typically do not remain suspended in the air for extended periods the way chickenpox does. Influenza primarily spreads through larger droplets that travel only a short distance, and strep throat is generally spread through direct contact with infected fluids. Pertussis can have airborne spread but is more closely associated with direct droplet transmission when a person is in close contact with an infected individual.

Therefore, chickenpox stands out in this context as a highly contagious disease that primarily spreads through airborne transmission.
