Which disease is commonly known as German measles and is preventable by vaccination?

Rubella, commonly referred to as German measles, is a contagious viral infection characterized by a distinctive red rash, fever, and cold-like symptoms. It is preventable through vaccination, specifically the MMR vaccine, which protects against measles, mumps, and rubella.

Vaccination is crucial because rubella can lead to serious complications, especially in pregnant women, where it can cause congenital rubella syndrome, leading to severe birth defects. The uptake of the rubella vaccine has significantly reduced the incidence of this disease.

In contrast, rubeola is another name for measles, which is a different disease and is not referred to as German measles. Varicella refers to chickenpox, which is also preventable by vaccination but is unrelated to rubella. Conjunctivitis, commonly known as pink eye, is an inflammation of the eye and does not pertain to the topic of vaccination for viral diseases. The clear identification of rubella as both the proper term associated with the description provided and its preventability through vaccination makes it the correct answer.
