Health authorities are racing to trace dozens of people who disembarked from a hantavirus-hit cruise ship on the island of St Helena in the South Atlantic.
The operator of the Dutch vessel said 29 passengers, of at least 12 different nationalities, left the MV Hondius on 24 April. The Dutch government gave a different figure of 40.
A 69-year-old Dutch woman who later died in South Africa was among those. Two other people died on the ship, which set sail from southern Argentina a month ago. Their deaths are now under investigation.
On Thursday, the World Health Organization (WHO) said five of eight suspected cases of hantavirus were now confirmed. But while it was serious, the WHO said it “assesses the public health risk as low”.
