Explore the recorded discovery and history of Rubella virus, with source links and stated limits.
Rubella is caused by a different virus from measles despite the nickname 'German measles'. CDC describes a usually mild illness, often with few noticeable symptoms, that spreads when an infected person coughs or sneezes. Its most serious documented consequence is harm to a developing baby when someone is infected during pregnancy.
CDC's Pink Book records that rubella was first described as a separate disease in the German medical literature in 1814, which is the source of the common name 'German measles'. It had previously been considered a variant of measles or scarlet fever.
Norman Gregg reported congenital cataracts in infants born after maternal rubella in 1941, the first published recognition of congenital rubella syndrome.
Rubella virus was first isolated in 1962 by two independent groups. The first rubella vaccines were licensed in 1969, and a combined MMR vaccine followed in 1971.
CDC records that endemic rubella was declared eliminated in the United States in 2004, with fewer than 10 cases reported annually. Since 2012 all reported US cases had evidence of infection acquired outside the country, and rubella remains common in other parts of the world.
An 1814 clinical description and the 1962 isolation record scientific recognition, not a first infection. The name 'German measles' comes from the language of that description and does not locate a first case or an origin.
