Rubella is spread by which virus ?

Question

Accepted Answer

Rubella is spread by the Toga virus, which is why Option 2 is the correct answer. Here is a detailed explanation:

1. **Explanation for Option 2 (Toga virus):**
   - Rubella, also known as German measles, is caused by the Rubella virus, which belongs to the Togaviridae family. Specifically, it is classified under the genus Rubivirus within this family. The Togaviridae family is known for its single-stranded RNA viruses, which are enveloped and have a positive-sense RNA genome. The Rubella virus is the only member of the Rubivirus genus, and it is responsible for causing the rubella infection in humans. This virus is primarily transmitted through respiratory droplets when an infected person coughs or sneezes. The association of Rubella with the Toga virus family is well-documented in virology, making Option 2 the correct choice.

2. **Explanation for why other options are incorrect:**
   - **Option 1 (Para virus):** The term "Para virus" is not a recognized classification for the Rubella virus. While there are paramyxoviruses, which are a different group of viruses, they are not related to Rubella. Paramyxoviruses include pathogens like the measles virus and mumps virus, but not the Rubella virus.
   
   - **Option 3 (Mixo virus):** The term "Mixo virus" likely refers to the Myxovirus group, which includes orthomyxoviruses and paramyxoviruses. Orthomyxoviruses are known for causing influenza, while paramyxoviruses include viruses like measles and mumps. Neither of these groups includes the Rubella virus, which is part of the Togaviridae family.
   
   - **Option 4 (D. N. A. virus):** Rubella is caused by an RNA virus, not a DNA virus. DNA viruses have a different genetic material structure compared to RNA viruses. The Rubella virus, being an RNA virus, does not fit into the category of DNA viruses, which further confirms that Option 4 is incorrect.

In conclusion, the Rubella virus is correctly classified under the Toga virus family, making Option 2 the accurate answer. The other options do not align with the scientific classification of the Rubella virus.
