Rubivirus is a genus of viruses that includes the causative agent of rubella, also known as German measles. This virus is an RNA virus and is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. Rubella is characterized by a mild rash and fever, but it can have serious consequences if contracted during pregnancy, leading to congenital rubella syndrome. The rubella vaccine has significantly reduced the incidence of this virus in many parts of the world. Vaccination is crucial for preventing outbreaks and protecting vulnerable populations, especially pregnant women. Public health initiatives continue to promote vaccination to maintain herd immunity against Rubivirus.
