Flavivirus
Herpesvirus
Hepatitis D Virus (HDV) requires co-infection or superinfection with which other hepatitis virus?
HAV
HEV

Herpesviruses are characterized by their ability to cause:
Acute, self-limiting infections only
Non-enveloped, SS-DNA infections
Latent viral infection which can be reactivated
Only mild childhood diseases
Reactivation of latent herpesvirus infections is commonly observed among all of the following EXCEPT:
Individuals with underlying medical conditions
Immunosuppressed patients
Patients undergoing corticosteroid therapy
Healthy, young adults
Gingivostomatitis and ulcerative mouth lesions commonly seen above the waist are primarily associated with which Herpes Simplex Virus (HSV) type?
HSV-2
HSV-1
Varicella Zoster Virus
Cytomegalovirus
A link has been established between infection with which virus and cervical carcinoma?
Human Herpesvirus Type 6
Varicella Zoster Virus (VZV)
Herpes Simplex Virus (HSV) 2
Epstein Barr Virus (EBV)
Serological tests are NOT generally recommended for the laboratory diagnosis of HSV infections because:
The viruses are non-antigenic.
They only detect IgM, not IgG.
Uninfected individuals may possess antibodies against HSV-1 and HSV-2.
Cell culture is much faster and more reliable.
The appearance of the rash in Chicken Pox is often described as resembling:
Dew drops on a rose petal
Sandpaper
Target lesions
Bull's eye
Reye's Syndrome, a complication associated with Varicella Zoster infection, is primarily caused by treatment with:
Antivirals
Corticosteroids
Aspirin
Antibiotics
Herpes Zoster (Shingles) is the reactivation of VZV that remains latent in the:
Epithelial cells of the skin
Dorsal root ganglia of peripheral or cranial nerves
Liver parenchyma
Lymphatic vessels
Epstein Barr Virus (EBV) was first isolated from malignant cells of:
Cervical carcinoma
Burkitt's Lymphoma
Kaposi's Sarcoma
Hodgkin's Disease
The presence of 50% lymphocytes appearing as atypical lymphocytes is a characteristic finding in the peripheral blood of a patient with:
Chicken Pox
Herpetic whitlow
Infectious Mononucleosis
Erythema infectiosum
