A new suspected case of hantavirus has been reported in a British national, health chiefs have warned.
The UK Health Security Agency said the new case was reported on the remote island area of Tristan da Cunha, in Saint Helena, where passengers on the cruise ship has disembarked last month.
“None of the British citizens onboard are currently reporting symptoms, but they are being closely monitored,” UKHSA said.
It comes after two British nationals have confirmed hantavirus, who are currently isolating at home.
Tedros Ghebreyesus, director-general of the World Health Organisation (WHO), said eight cases of the virus have been reported, with five confirmed and three suspected.
Although none of the passengers or crew currently on board are symptomatic, Dr Ghebreyesus warned more cases may be identified given the incubation period of the virus, which can be up to six weeks, but said the public health risk is low.
Additionally, four British nationals remain in overseas territory St Helena after disembarking the cruise on the tiny island in the South Atlantic Ocean.

The woman had been admitted to a hospital in Amsterdam on Thursday with signs of a possible infection.

Could cruise boat hantavirus be the next global pandemic? Experts sound off on if Covid-era lockdowns could return
As the world continues to monitor an outbreak of deadly hantavirus on a Dutch cruise ship off the West African coast, many on social media have wondered if the rare, rodent-borne illness could trigger the next global pandemic and reinstate Covid-era lockdowns.
Researchers are tracing passengers who were potentially exposed to the virus in Georgia, California, Arizona, Virginia and Texas and in other countries around the world.
But experts still say there is little reason to believe hantavirus – and even this rare strain – will spread widely.
