How is rubella primarily transmitted?

Rubella is primarily transmitted through respiratory droplets that are released into the air when an infected person coughs or sneezes. This airborne transmission allows the virus to spread easily in crowded places or enclosed environments where people are in close proximity to one another. As a result, if someone inhales these droplets, they can become infected.

Other transmission methods, such as contact with contaminated surfaces or spread via bodily fluids, do not play a significant role in transmitting rubella. While a rash is a characteristic of rubella infection, direct contact with the rash itself does not significantly contribute to the spread of the virus. This makes airborne transmission the predominant route for rubella.
