Breakdowns in infection control practices led to a recent hepatitis A outbreak among hospital patients and healthcare workers, according to a study seeking to identify risk factors for infection.
All infections came from a single patient with an undiagnosed hepatitis A infection.
In this study, healthcare works with suspected or confirmed hepatitis A infections discussed their exposures and activities and patient medical records and hospital administrative records were analyzed to identify common exposures.
In total, 6 healthcare workers and 2 patients had laboratory-confirmed infections, likely stemming from exposure to a to a homeless patient with an undiagnosed HAV infection. The patient had a history of recreational substance use. The study authors suggested that hepatitis A should be included in the differential diagnosis of patients with a history of recreational substance use and homelessness.
Deviations from standard precautions and hand hygiene protocol were noted.
