An outbreak of hepatitis A in an intensive care unit

We describe an outbreak of hepatitis A that occurred in an Intensive Care Unit (ICU) in a regional hospital in North Queensland. Seven people were infected including two patients, two close contacts of the index patient and three ICU nursing staff. The index case was admitted with an overdose and multiple trauma; he was not suspected to be incubating hepatitis A. The outbreak was initiated as a result of inadequate precautions taken whilst handling the index patient's bile. Problems identified upon reviewing the outbreak were inadequate terminal cleaning of equipment, food consumption in the ICU and inadequate handwashing practices. Implementation and maintenance of standard infection control practices is vital if further outbreaks of hospital-acquired hepatitis A and other enteric infections are to be avoided. We also suggest that the inactivated hepatitis A vaccine be considered for ICU staff.
