a. Herpesviruses
The correct answer is a. Herpesviruses.
Cytomegalovirus (CMV), Epstein-Barr virus (EBV), and Varicella-Zoster virus (VZV) are all members of the Herpesviridae family. These viruses are characterized by a double-stranded DNA genome and the ability to establish lifelong latent infections in their hosts.
CMV is a ubiquitous virus that can cause severe disease in immunocompromised individuals, such as transplant recipients or people with HIV.
EBV is the cause of infectious mononucleosis (“mono”) and is associated with a variety of cancers, including Hodgkin’s lymphoma, Burkitt’s lymphoma, and nasopharyngeal carcinoma.
VZV causes chickenpox (varicella) and shingles (herpes zoster) and can also cause complications such as pneumonia or encephalitis.
