Rubella virus, scientific name Rubivirus rubellae, is a member of the genus Rubivirus and belongs to the family of Matonaviridae, whose members commonly have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid.
The 1962–1965 rubella epidemic was an outbreak of rubella across Europe and the United States. [ 1 ] [ 2 ] The Rubella virus, also known as the German measles, is a single-stranded RNA virus from the family Togaviridae and genus Rubivirus . [ 3 ]
Rubella, also known as German measles or three-day measles, [6] is an infection caused by the rubella virus. [3] This disease is often mild, with half of people not realizing that they are infected. [ 1 ] [ 7 ] A rash may start around two weeks after exposure and last for three days. [ 1 ]
Congenital rubella syndrome (CRS) occurs when a human fetus is infected with the rubella virus (German measles) via maternal-fetal transmission and develops birth defects. [1] The most common congenital defects affect the ophthalmologic, cardiac, auditory, and neurologic systems.
[3] [5] [12] [13] [14] Other names include morbilli, rubeola, red measles, and English measles. [1] [2] Both rubella, also known as German measles, and roseola are different diseases caused by unrelated viruses. [15] Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days.
An RNA virus is a virus characterized by a ribonucleic acid based genome. [1] The genome can be single-stranded RNA ( ssRNA ) or double-stranded ( dsRNA ). [ 2 ] Notable human diseases caused by RNA viruses include influenza , SARS , MERS , COVID-19 , Dengue virus , hepatitis C , hepatitis E , West Nile fever , Ebola virus disease , rabies ...
Rubella vaccine is a vaccine used to prevent rubella. [1] Effectiveness begins about two weeks after a single dose and around 95% of people become immune. Countries with high rates of immunization no longer see cases of rubella or congenital rubella syndrome. When there is a low level of childhood immunization in a population it is possible for ...
The polyhedral capsid from which the virus gets its name is an extremely stable protein crystal that protects the virus in the external environment. It dissolves in the alkaline midgut of moths and butterflies to release the virus particle and infect the larva. [20] An example of an insect that it infects is the fall webworm. [21]
