Kaposi's sarcoma is commonly associated with which virus?

• A. HIV
• B. HPV-8
• C. EBV
• D. CMV

Answer: (B)

Kaposi's sarcoma is predominantly associated with Human Herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV). This virus plays a crucial role in the development of Kaposi's sarcoma, as it can induce the transformation of endothelial cells, leading to the characteristic lesions seen in this cancer. In people with weakened immune systems, such as those with HIV/AIDS, HHV-8 can become more active, contributing to the development of Kaposi's sarcoma. However, the direct causative relationship is primarily between Kaposi's sarcoma and HHV-8 rather than being merely associated through HIV. Thus, identifying HHV-8 as the virus linked to Kaposi's sarcoma highlights its specific role in the pathogenesis of this malignancy. Understanding this connection is vital for comprehending the mechanisms behind Kaposi's sarcoma and its increased prevalence in immunocompromised individuals.
