Varicella belongs to which family of virus
## **Core Concept**
Varicella, commonly known as chickenpox, is caused by the varicella-zoster virus (VZV). This virus belongs to the family of viruses that cause infections typically characterized by the development of rash and other symptoms. The family in question is known for containing several viruses that affect humans, often causing skin and mucous membrane lesions.
## **Why the Correct Answer is Right**
The varicella-zoster virus (VZV) belongs to the **Herpesviridae** family. This family of viruses is known for its members causing lifelong infections, often characterized by latency and reactivation. The Herpesviridae family includes several viruses that cause human diseases, such as herpes simplex virus (HSV), Epstein-Barr virus (EBV), and human cytomegalovirus (HCMV). VZV specifically causes chickenpox (varicella) upon primary infection and shingles (herpes zoster) upon reactivation.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not correspond to the correct family name for VZV.
- **Option B:** This option is incorrect for the same reason; it does not accurately represent the family to which VZV belongs.
- **Option D:** This option is incorrect as it does not denote the Herpesviridae family.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the **Herpesviridae** family includes viruses that establish latent infections. For VZV, this means that after a person recovers from chickenpox, the virus can remain latent in nerve cells and reactivate years later to cause shingles. This characteristic is crucial for understanding the long-term implications of VZV infection.
## **Correct Answer:** C. Herpesviridae.
