Question

Rubella virus belongs to which family?

• A. Rheovirus
• B. Togavirus
• C. Picornavirus
• D. Orthomyxo

Answer 1

The Correct Option is B

In the field of microbiology, the classification of viruses into their respective families is fundamental to understanding their characteristics and behaviors. The question pertains to which family the Rubella virus belongs.

Explanation:

The Rubella virus is known to cause rubella, commonly referred to as German measles. It is crucial to correctly identify its viral family to understand its morphology, replication, and pathogenesis.

Analysis of Options:

• Rheovirus: This is incorrect. Rheoviruses belong to the family Reoviridae, which are non-enveloped viruses with double-stranded RNA.
• Togavirus: This is the correct answer. The Rubella virus is indeed a member of the Togaviridae family. Togaviruses are enveloped and have a single-stranded positive-sense RNA genome.
• Picornavirus: This is incorrect. Picornaviruses are part of the family Picornaviridae, which includes viruses like poliovirus, and are non-enveloped with a positive-sense RNA genome.
• Orthomyxo: This is incorrect. Orthomyxoviruses belong to the family Orthomyxoviridae, which include influenza viruses and are characterized by a segmented, single-stranded negative-sense RNA genome.

Conclusion: The Rubella virus is classified within the Togaviridae family, making 'Togavirus' the correct answer to this query.
