The Isle of Man Steam Packet Company has confirmed an Island-based crew member has tested positive for COVID-19.
It says the individual, who does not hold a passenger-facing role, had the test while off-duty and has been placed in immediate isolation.
Contact tracing is underway and a handful of colleagues who the individual has been in contact with are also self-isolating.
The Steam Packet Company says it has clear policies in place for its crew to prevent the spread of COVID-19 on both its vessels and at its ports.
