Oral Herpes

Exams and Tests

A doctor will base a diagnosis on information you provide and on physical examination. The characteristic appearance of the herpes sores leaves little doubt. Further testing is usually not necessary.

If you require a definitive diagnosis, for instance, if your infection involves other organ systems, the doctor may conduct laboratory tests.

  • A sample from the sores to identify the virus
  • A culture analysis
  • A staining test called the Tzanck smear
  • Antigen and antibody studies
  • Blood sampling for antibody studies

Medical Treatment

Treatment includes medication for fever and taking plenty of fluids.

  • A topical anesthetic such as viscous lidocaine (Dilocaine, Nervocaine, Xylocaine, Zilactin-L) may be prescribed to relieve pain.

  • Some people may require hospital admission:
    • Those with severe local infection
    • People whose infection has spread to other organ systems
    • People with weakened immune systems

    • Infants younger than 6 weeks
