Segmented double stranded RNA virus is seen in –
## **Core Concept**
The question tests knowledge of viral characteristics, specifically the type of genetic material and its structure. Segmented double-stranded RNA (dsRNA) viruses belong to the *Reoviridae* family, which includes several viruses affecting humans and animals.
## **Why the Correct Answer is Right**
The correct answer, , refers to *Rotavirus*, which is a type of virus known to have a segmented double-stranded RNA genome. *Rotavirus* is a major cause of severe diarrhea in infants and young children worldwide. The segmented dsRNA genome is characteristic of the *Reoviridae* family, allowing for the reassortment of genetic material, which is a significant feature for the evolution and diversity of these viruses.
## **Why Each Wrong Option is Incorrect**
* **Option A:** - This option is incorrect because is not specifically known for having a segmented dsRNA genome.
* **Option B:** - This option is incorrect as it does not correspond to a virus with a segmented dsRNA genome.
* **Option D:** - This option is incorrect because it refers to another type of virus or condition that does not match the characteristic of having a segmented dsRNA genome.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that *Rotavirus* infections are a leading cause of severe gastroenteritis in children under 5 years old worldwide. The introduction of the *Rotavirus* vaccine has significantly reduced the incidence of severe *Rotavirus* infections. The unique characteristic of having a segmented dsRNA genome allows *Rotavirus* to undergo genetic reassortment, which can lead to new strains.
## **Correct Answer:** . Rotavirus
