Two cases of incidentally diagnosed chronic hepatitis B of probable vertical transmission are reported. The first case is a 32 year-old pregnant patient referred to our center for fetal monitoring due to oligohydramnios; during her hospitalization the patient went into labor, the professional assisted her without gloves and there was an important contact with blood.Serological tests were performed to the patientrevealing to be a HBsAgcarrier, but negative for HBeAg, positive for anti-HBe Ac and HBcIgG, negative for anti HBs and HBc Ac IgM. The second case is a patient with Systemic Lupus Erythematosus under immunosuppressive treatment, with a history of having a deceased mother and two siblings with HBV infection. Serology revealedHBsAg (+) with viral load of 113 copies, HBeAg (-),hepatitis C (-), HBcIgG (+), HBcIgM (-), anti-HBe (+). The patient received treatment with tenofovir. Both patients were incidentally diagnosed and considered to be chronic inactive hepatitis B carriers due to probable vertical transmission based on their family history. These two cases constitute a wake-up call about the vertical transmission of the virus and the importance of performing the screening in all pregnant women in the first prenatal care.

Palabras clave : Chronic hepatitis B; vertical transmission; incidentally detection asymptomatic HBsAg carriers.
