Togavirus rubella

It affects children and adolescents worldwide and can also affect young adults. When rubella virus infects susceptible women early in pregnancy, it may be transmitted to the fetus and may cause birth defects. Therefore, accurate diagnosis is critical in pregnancy. The rubella virus is a member of the genus Rubivirus in.


This was the first published recognition of congenital rubella syndrome (CRS).

One of the more well-known diseases in this family is known as rubella. This is a mild disease caused by the rubella virus that is characterized by a fever and rash. Secular Trends in the United States. The togavirus genome is non-segmented and contains a molecule of linear, positive-sense, single-stranded RNA. The alphaviruses are classified on the basis of antigenic properties.


Togavirus virions consist of an envelope and a nucleocapsid. R DEPT: OF SWASTHAVRITTA 2. Most people who have had rubella or the vaccine are protected against the virus for the rest of their life.

Some of them are zoonotic viruses, including Venezuelan equine encephalitis virus (VEEV). Rubella is usually a mild illness. English dictionary definition of togavirus. Humans are the only known host, with seasonal epidemics occurring every 5-years over a worldwide distribution.

EPIDEMIOLOGY: Man is only host. Disease is spread by droplet inhalation. Complications: Measles have complications like pneumonia, diarrhea, and middle ear infection. Rubivirus contains non-arthropod-borne viruses, including the causative agent of German measles.


In togavirus …is carried by mosquitoes, and Rubivirus , which contains rubella , or German measles, virus. The presence of rubella IgM in cord blood or serum samples taken in infancy. Detection of rubella antibodies at a time when maternal antibodies should have disappeared (approx.months of age) Isolation of rubella virus or detection of rubella virus nucleic acid from infected infants in the first few months of life.


Alphaviruses perform host transcription shutoff by inhibiting host RNA polymerase II.

Host RNA-pol II catalytic subunit is targeted for degradation as early as 4-6h p. It can cause miscarriage or birth defects. People without symptoms can still spread it. There is no treatment, but the measles-mumps- rubella (MMR) vaccine can prevent it.


Illness and treatment: Acquired rubella is usually mild with fever and a maculopapular rash moving down from the face to include the entire body. Up to of infections are inapparent. Due to vaccination, the CDC no longer considers rubella a major public health threat in the United States. Until recently, togaviruses were classified in the same family as the flaviviruses.


Modern molecular techniques allowed virologists to separate the two families based on gene expression. The infection is usually mild with fever and rash. But, if a pregnant woman gets infecte the virus can cause serious birth defects.


For example, pneumonia and encephalitis are caused by measles.
