90-Second Read: Hantavirus: How are countries responding to the cruise virus?

The last passengers and some crew members have now left a Dutch cruise ship at the centre of an outbreak of Hantavirus, after disembarking at Granadilla port in south-east Tenerife. Some disembarked before the first confirmed case of Hantavirus was reported on 4 May. There are currently no recorded cases of Hantavirus in the country, with officials saying the risk remains "extremely low". The WHO has so far reported nine cases in total, seven confirmed and two suspected. Here's how countries are dealing with the virus: Twenty British nationals, one German national who lives in the UK and one Japanese passenger arrived at Arrowe Park Hospital in Merseyside, north-west England late on Sunday.

The country has confirmed its first case of Hantavirus after a French national developed systems while travelling on a chartered flight from Tenerife to Paris. The Public Health Agency of Canada has said this could be extended to 42 days, citing the Hantavirus's incubation period. A man who left the cruise in Saint Helena has tested positive for Hantavirus since returning home. The UK, US and EU are asking all citizens returning home from the virus-hit MV Hondius to self-isolate for about six weeks. An American and a French national who had returned home have since tested positive, authorities said, while a Spaniard has a suspected case.

Three people, a Dutch couple and a German woman, had died after travelling on the ship, with two of them confirmed to have had the virus. The group was flown to Manchester Airport on a chartered flight, with the UK's Health Security Agency (UKHSA) saying "strict infection control measures" were in place throughout the journey. Public Health Minister Sharon Hodgson said none of the passengers were symptomatic, but they will be monitored closely "as part of a precautionary isolation period". With no cases or symptoms among them and our stringent monitoring and isolation measures, the risk to the public remains extremely low," she added. The EU's guidance is similar to the UK's, with citizens returning to their respective member nations advised to "undergo medical triage by trained healthcare professionals".

A total of 31 British nationals, a mix of passengers and crew, set sail on the cruise. The WHO has previously said the first two cases had "travelled through Argentina, Chile and Uruguay on a bird-watching trip which included visits to sites where the species of rat known to carry the virus was present". They should then self-isolate and monitor their symptoms for six weeks, seeking immediate medical help "if symptoms develop", according to advice from the European Centre for Disease Prevention and Control (ECDC). They were transported in vans directly to their home addresses, the government said, adding that those in isolation would be contacted daily by the relevant health officials "to ensure that any symptoms are identified and appropriate care can be provided promptly". But WHO officials insisted.
