How does measles spread?

Measles primarily spreads through the air, making it highly contagious. When an infected person breathes, coughs, or sneezes, they release virus-containing droplets into the air. These droplets can linger in the air for up to two hours after the infected person has left the area. If another person inhales these droplets, they can become infected with the measles virus.

This airborne transmission is crucial in understanding how quickly measles can spread in a population, especially among those who are unvaccinated. Measles can also infect individuals who are in the same room with the infected person, further underscoring the importance of vaccination and herd immunity in preventing outbreaks.

The other methods of transmission mentioned are not applicable to measles. Direct contact with skin, contaminated surfaces, and drinking water do not play a role in the spread of the virus, emphasizing the specific and effective nature of airborne transmission in this case.
