Document Summary

Herpes viruses: enveloped virus, once you are infected, the virus remains with you forever. Herpes viruses: latent viruses: herpes tends to be latent viruses and cause recurrent infections, more significant problem in immunocompromised individuals, varicella zoster virus (vzv) Difficult to identify symptoms, but virus lasts forever: herpes simplex viruses (hsv1, hsv2) Hsv1 typically affects the upper body (oral herpes), whereas hsv2 affects genitals: epstein barr virus (ebv): infectious mononucleosis. Can be confused with leukemia because of the large amount of lymphocytes in the body therefore, many tests are performed to distinguish the two. Herpes as oncogenic viruses: some herpes viruses have oncogenic properties, epstein barr virus (ebv) has been associated with malignancies/cancers such as: Lymphomas in immunosuppressed organ transplant recipients: a herpes virus type 8 is associated with kaposi"s sarcoma (aggressive cancer that affects the cells making blood vessels) Other oncogenic viruses: human papilloma virus (hpv)
