What virus is responsible for causing German measles?

The virus responsible for causing German measles is the Rubella virus. Rubella is a contagious viral infection characterized by a mild rash and fever, and is especially concerning when contracted during pregnancy due to the risk of congenital rubella syndrome, which can lead to serious birth defects. The disease is typically transmitted through respiratory droplets when an infected person coughs or sneezes.

Understanding this virus is crucial because it highlights the importance of vaccination, particularly the MMR (measles, mumps, rubella) vaccine, in preventing outbreaks and protecting those who are most vulnerable, such as pregnant women and their unborn children.

The other viruses listed do not cause German measles. Parvovirus is known for causing fifth disease, Orthomyxovirus is responsible for influenza, and Rhinovirus is primarily associated with the common cold. Thus, only the Rubella virus is the correct identification of the pathogen associated with German measles.
