Epstein-Barr Virus (EBV) Infection
EBV is a herpesvirus responsible for infectious mononucleosis (glandular fever). It is widespread in Sri Lanka, affecting children and young adults, but often goes undiagnosed or misdiagnosed.
Symptoms of EBV Infection
- Prolonged fever
- Sore throat and swollen tonsils
- Enlarged lymph nodes (especially neck)
- Fatigue lasting weeks
- Occasionally rash and liver involvement
Diagnosing EBV
Blood tests look for EBV-specific antibodies such as:
- Viral Capsid Antigen (VCA) IgM: indicates recent infection
- VCA IgG: indicates past infection
- EBV Nuclear Antigen (EBNA): appears later, indicates past infection
Why EBV Can Be Confusing
- Symptoms overlap with other viral infections.
- Lab results may be unclear without clinical context.
- In Sri Lanka, lack of awareness leads to delayed diagnosis.
When to Consult a Virologist
- Persistent unexplained fever with lymphadenopathy
- Confusing or conflicting test results
- Suspected complications or immune suppression
