Carriers are patients with chronic but inactive infection:

  • HBsAg positive for more than 6 months plus
  • Persistently normal liver function (at least 3 times in 12 months) and
  • No evidence of viral replication (negative HBeAg and/or HBV DNA < 2000 IU/ml)

Patients classified as inactive carriers need to be monitored once a year with CBC, renal and liver tests, HBsAg,
abdominal ultrasound. If possible, do HBV-DNA every 3 years.

They are not highly infectious but close contacts should be immunized and appropriate precautions should be followed.
