What diseases are categorized as airborne transmission diseases?

Diseases categorized as airborne transmission diseases are those that can be spread through respiratory droplets that remain suspended in the air for a period of time, allowing individuals to become infected even when they are not in direct contact with the source of infection. This transmission method is particularly significant for pathogens that can survive in the air long enough to be inhaled by others.

The correct choice lists tuberculosis (TB), measles, and chickenpox as airborne diseases. Tuberculosis is primarily spread through droplets expelled when an infected person coughs or sneezes. Measles is highly contagious and can spread through respiratory droplets and the air, remaining infectious for up to 2 hours in the environment after an infected person leaves. Chickenpox also spreads through airborne transmission via the varicella-zoster virus, especially when an infected person coughs, sneezes, or even breathes.

This set of diseases demonstrates how airborne pathogens can lead to outbreaks in communal settings, making it essential for healthcare facilities and public health responses to implement proper precautions like ventilation and isolation measures for infected individuals.
