Which of the following diseases is caused by airborne pathogens?

Measles is caused by airborne pathogens, specifically the measles virus. It is highly contagious and is transmitted through respiratory droplets when an infected person coughs or sneezes. These droplets can remain suspended in the air or settle on surfaces, making it possible for individuals who are not immune to become infected even after the infected person has left the area. Understanding that measles is an airborne disease highlights the importance of vaccination and public health measures to prevent outbreaks.

In contrast, diabetes, hypertension, and obesity are not caused by airborne pathogens; instead, they are primarily related to lifestyle factors, genetics, and environmental influences. These conditions are chronic and cannot be spread from person to person as infectious diseases like measles can.
