Which highly contagious disease is NOT mentioned among airborne pathogens?

Rubella is considered a contagious disease, but it is primarily spread through respiratory droplets rather than being classified as an airborne pathogen. Airborne pathogens are typically those that can be transmitted through inhalation of dust particles or droplets that remain suspended in the air. Diseases like chickenpox, measles, and mumps are highly contagious and spread through airborne droplets.

In contrast, rubella, while still contagious, is not typically categorized with the same airborne transmission classification as the other diseases listed, which is why it stands out in this context. Understanding these distinctions is essential in the field of public health and containment strategies.
