Epstein-Barr Virus

Epstein-Barr Virus (EBV) is one of the most common human viruses globally. A member of the Herpesviridae family, it establishes lifelong latent infection in B lymphocytes. While often asymptomatic in childhood, primary infection during adolescence or adulthood frequently manifests as infectious mononucleosis. EBV is also etiologically linked to various malignancies, including Burkitt lymphoma and nasopharyngeal carcinoma.

EBV is primarily transmitted via saliva, earning it the moniker "the kissing disease." It can also spread through blood or semen during organ transplantation or sexual contact. It is not typically airborne.

Following inoculation in the oropharynx, the virus infects B lymphocytes and epithelial cells. It induces B-cell proliferation and triggers a robust T-cell response, leading to the lymphocytosis observed in acute infection. The virus then enters a state of latency, periodically reactivating and shedding in saliva.

Approximately 90-95% of the adult population worldwide is seropositive. Infection usually occurs in early childhood in developing nations (often asymptomatic) and delays until adolescence in high-income settings, where clinical mononucleosis is more common.

Age (adolescence), close contact with infected individuals (crowded settings), immunosuppression (HIV/AIDS, transplant recipients), and sharing personal items (drinking glasses).

A. Early Symptoms
Fatigue, malaise, mild headache, sore throat. B. Common Symptoms
Fever, severe pharyngitis (exudative), cervical lymphadenopathy, splenomegaly, hepatomegaly, anorexia. C. Advanced Symptoms
Palatal petechiae, periorbital edema, severe tonsillar hypertrophy causing airway obstruction. D. Emergency Symptoms
Splenic rupture (sudden, severe left upper quadrant pain), respiratory distress, severe neurological deficits (encephalitis).

Fever, posterior cervical lymphadenopathy, tonsillar exudates, hepatosplenomegaly, and occasionally a maculopapular rash (notably if amoxicillin was administered).

A. Clinical Assessment: Presence of the classic triad (fever, pharyngitis, lymphadenopathy).
B. Laboratory Testing: Heterophile antibody test (Monospot), EBV-specific serology.
C. Imaging Studies: Ultrasound for splenomegaly.
D. Functional Tests: Liver function tests.
E. Biopsy Findings: Lymph node biopsy if lymphoma is suspected.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Streptococcal pharyngitis, Cytomegalovirus (CMV), HIV.

Test Name: Monospot Test
Type: Blood Test
Purpose: Rapid screening for heterophile antibodies.
Expected Findings: Positive in 70-90% of adults.
Interpretation: Positive indicates acute EBV infection. Test Name: EBV Serology (VCA, EBNA)
Type: Blood Test
Purpose: Differentiate acute vs. past infection.
Expected Findings: IgM VCA present in acute; IgG EBNA present in past.
Interpretation: Confirmatory.

Abdominal Ultrasound: Used to assess for splenomegaly and risk of splenic rupture in athletes.

Group A Streptococcal pharyngitis (lacks lymphadenopathy/splenomegaly), Cytomegalovirus (CMV) infection, Acute HIV, Toxoplasmosis.

Splenic rupture, airway obstruction, hemolytic anemia, thrombocytopenia, encephalitis, and rare malignancies (lymphoma).

A. Lifestyle Modifications: Hydration, rest, avoidance of contact sports for 3-4 weeks.
B. Preventive Measures: Avoid sharing saliva-contaminated items.
C. Medical Treatment: Supportive; NSAIDs/Acetaminophen for pain. Avoid amoxicillin due to rash.
D. Surgical Treatment: Splenectomy only for rupture.
E. Interventional Procedures: Airway management for obstructive tonsillar hypertrophy.
F. Rehabilitation: Gradual return to activity after 4 weeks.
G. Emergency Management: Fluids and analgesics.

Excellent for immunocompetent individuals; full recovery in 2-4 weeks. Chronic fatigue may persist for months.

Hand hygiene and avoiding contact with oral secretions of infected individuals.
