Nosocomial infection with hepatitis A.

W M Edgar, A D Campbell

The Journal of Infection

|January 1, 1985

Summary

Nosocomial spread of Hepatitis A virus (HAV) is rare. This case shows a patient shed HAV in feces 16 days before jaundice, highlighting potential transmission risks in healthcare settings.

Area of Science:

Hepatology
Infectious Diseases
Virology

Background:

Nosocomial (hospital-acquired) spread of Hepatitis A virus (HAV) is generally considered uncommon.
Understanding transmission dynamics is crucial for infection control in healthcare settings.

Observation:

An index case of Hepatitis A was identified within a healthcare facility.
The patient's clinical course and viral shedding patterns were meticulously documented.

Findings:

The index patient was excreting Hepatitis A virus in their feces 16 days prior to the onset of jaundice.
Alanine aminotransferase (ALT) levels, a marker of liver injury, peaked 17 days after the presumed start of viral shedding.

Implications:

This case underscores that Hepatitis A transmission can occur in healthcare settings under specific, albeit unusual, circumstances.
Early identification and isolation of infectious patients are critical to prevent nosocomial outbreaks.
Further research into the precise timing of viral shedding and infectivity in Hepatitis A is warranted.
