Two people who returned to the UK from a cruise ship hit by a hantavirus outbreak have been advised to self-isolate, the UK Health Security Agency said Wednesday.

“The risk to the general public remains very low,” the UKHSA however stressed.

UKHSA said “neither of these individuals is currently reporting symptoms. They are receiving advice and support from UKHSA and have been advised to self-isolate”.

The MV Hondius, where the outbreak happened, was off Cape Verde late Wednesday and heading toward Spain’s Canary Islands.

Spain’s interior ministry said late Wednesday that the evacuation of hantavirus ship passengers from the Canaries will start on May 11.

UKHSA said it was supporting a “small number” of people identified as close contacts of those on the boat, who were being offered support and were also self-isolating but not reporting any symptoms.

It confirmed that one British national was among three people with suspected hantavirus who have been evacuated from the Hondius to receive medical care in the Netherlands.

The agency noted it was in close contact with the medical teams providing their care.

It said the remaining British nationals on board can be repatriated once the ship docks at its next destination if they do not develop symptoms.

“None of the British citizens onboard are currently reporting symptoms but they are being closely monitored,” the agency added.

The Foreign Office in London was making arrangements for their return travel, while the UKHSA said it was “working with government to support them to isolate with regular testing and contact with healthcare professionals”.
