GENEVA: The World Health Organization said Thursday that more cases of the hantavirus could emerge but expected the outbreak to be “limited” if precautions are taken, after the disease killed three passengers from a cruise ship.
Another sick passenger from the MV Hondius landed in Europe earlier in the day, as the vessel headed to a Spanish island and health officials scrambled to map the outbreak of the potentially deadly human-to-human strain.
The fate of the Hondius sparked international alarm after three people travelling on it died, though health officials have played down fears of a wider global outbreak from the rat-borne virus, which is less contagious than Covid-19.
WHO chief Tedros Adhanom Ghebreyesus told journalists in Geneva that five confirmed and three suspected cases had been reported overall, including the three deaths.
“Given the incubation period of the Andes virus, which can be up to six weeks, it’s possible that more cases may be reported,” he said, referring to the rare strain detected aboard the Hondius, which can be transmitted between humans.
His prediction was proved swiftly correct, with the Leiden University Medical Centre in the Netherlands announcing later on Thursday another patient had tested positive.
But the WHO’s emergency alert and response director Abdi Rahman Mahamud insisted: “We believe this will be a limited outbreak if the public health measures are implemented and solidarity shown across all countries.”
People thought to have contracted the virus are being treated or isolating in Britain, Germany, the Netherlands, Switzerland and South Africa.
“This is not the start of an epidemic. This is not the start of a pandemic,” WHO epidemic and pandemic preparedness and prevention director Maria Van Kerkhove insisted. “This is not Covid.”
Hantavirus is a rare respiratory disease that is usually spread from infected rodents and can cause respiratory and cardiac distress as well as haemorrhagic fevers.
There are no vaccines and no known cure for it, meaning that treatment consists solely of attempting to relieve the symptoms.
A passenger is thought to have contracted the virus before boarding the ship in Argentina and eventually infected others on board as it sailed across the Atlantic.
Three evacuees were whisked away from the ship on Wednesday and a fourth landed on Thursday in Amsterdam, said the vessel’s operator, Netherlands-based Oceanwide Expeditions.
“No symptomatic individuals are present on board” the ship at the moment, as it sails toward the Spanish island of Tenerife, it said in a statement.
Two people who returned to the UK from the ship have been advised to self-isolate, the UK Health Security Agency said, adding they were asymptomatic and insisting the risk to the public was “very low”.
