Name any two air borne diseases and how does the disease cause spreading of microbes?

Two common airborne diseases are:

1. Tuberculosis: Tuberculosis is a bacterial infection caused by *Mycobacterium tuberculosis*. It primarily affects the lungs and causes symptoms like cough, fever, weight loss, and night sweats. The bacteria are released into the air when an infected person coughs, sneezes, or speaks. When someone else inhales these airborne droplets, they can become infected with the bacteria.

2. Measles: Measles is a highly contagious viral infection caused by the measles virus. It is spread through respiratory droplets produced by an infected person when they cough or sneeze. The droplets can remain suspended in the air for several hours and can be inhaled by others, leading to infection. Measles is known for its characteristic symptoms of rash, fever, cough, and runny nose.

In both cases, the airborne nature of the microbes allows for easy and rapid spreading of the diseases. By inhaling the infected droplets, a susceptible person can become infected without having direct physical contact with an infected individual. This is why maintaining good respiratory hygiene, such as covering the mouth and nose when coughing or sneezing, is crucial in preventing the spread of airborne diseases.
