What is the primary transmission route of Measles, Mumps, and Rubella?

Measles, Mumps, and Rubella (MMR) are primarily transmitted through the respiratory route. These viral infections spread when an infected person coughs or sneezes, releasing respiratory droplets that contain the virus into the air. These droplets can then be inhaled by people nearby, leading to new infections. In addition, the viruses can remain infectious on surfaces for a certain period, which adds to the potential for transmission in public spaces. The respiratory transmission route is crucial for the spread of these viruses, which is why vaccination against them is essential for public health to create herd immunity and prevent outbreaks.
