Countries worldwide sought to prevent further spread of the hantavirus on Thursday after an outbreak on a cruise ship. Attempts were being made to track those who had already disembarked before the virus was detected and anyone who was in close contact with them since.
Three people – a Dutch couple and a German national – died in the outbreak on the MV Hondius. In total, five people are confirmed to have contracted the virus, with another three suspected cases, the World Health Organisation (WHO) said. Hantavirus is usually spread by rodents but can in rare cases be transmitted person-to-person.
All passengers who disembarked in St Helena in the south Atlantic Ocean, where the ship made a stop on April 24th, have been contacted, the ship’s operator said, adding this included people from at least 12 countries, among them seven British citizens and six from the US. The first confirmed case of hantavirus in this outbreak came in early May.
Plans were being developed to repatriate the two Irish passengers on board the cruise ship and to provide for their treatment and care during any required period of quarantine, the Department of Health said on Wednesday.
