What does rubella feed on?

Rubella, also known as German measles, is a viral infection caused by the rubella virus, which does not "feed" in the traditional sense like a living organism. Instead, it replicates within the host’s cells after entering the body, primarily through respiratory droplets. The virus utilizes the host's cellular machinery to reproduce and spread, leading to the symptoms associated with the infection. Vaccination is the most effective way to prevent rubella infection.
