Which of the following is a virus that is a member of family Togaviridae?

RUBELLA VIRUS (TOGAVIRIDAE) Rubella virus is a member of the Togaviridae family and the only member of the genus Rubivirus. The other Togavirus genus, Alphavirus, contains 26 members all of which are arthropod-borne.

What does Togaviridae cause?

The Togaviridae include the major causes of infectious arthropod-borne equine encephalitides and are divided into two main groups: the Alphaviridae—including Eastern equine encephalitis (EEE), Western equine encephalitis (WEE), and Venezuelan equine encephalitis (VEE)—and the Flaviviridae, including West Nile virus ( …

How is togavirus transmitted?

Togaviruses are important veterinary pathogens, and are transmitted via mosquitoes. Some of them are zoonotic viruses, including Venezuelan equine encephalitis virus (VEEV). Rubella virus is the only member of togavirus family that causes significant disease in human—German measles.

How is togavirus treated?

Treatment for togavirus infections is generally supportive in order to manage symptoms or complications. An effective measure in preventing rubella is through childhood immunizations using the MMR (Measles, Mumps Rubella) vaccine. There are no human vaccines available for the prevention of the alphavirus diseases.

How is alphavirus treated?

Treatment of illness: There is no specific treatment or established cure for alphaviruses. Supportive care (intravenous fluids, medicine to control fever and pain) is the standard treatment.

What is the meaning of togaviridae?

Medical Definition of Togaviridae : a family of single-stranded RNA viruses that have a spherical virion about 70 nanometers in diameter and that include the causative agents of German measles and the three forms of equine encephalitis — see alphavirus, rubivirus.

Are all Togaviruses arboviruses?

Togavirus, any of three genera of arthropod-borne viruses (arboviruses) of the family Togaviridae. Flaviviruses, once considered to be of the Togaviridae, are now designated as members of a separate family, Flaviviridae.

Is Togavirus RNA or DNA?

Genome Structure: Togavirus genome is a positive-strand RNA of 11 kb (Fig. 13.4 ). In addition to the genomic RNA that encodes a polyprotein for nonstructural proteins, a subgenomic RNA is expressed that encodes a polyprotein for structural proteins.

What are the symptoms of Togavirus?

The infection is often asymptomatic or dismissed as a minor flu-like illness. Symptoms may include: fever, myalgia, arthritis, headache, and an exanthem which appears first on trunk of host and progresses to extremities. Less common symptoms include: jaundice and myocardial damage.

How does rubella infect the body?
