Countries worldwide scrambled on Thursday to trace people who had left the cruise ship hit by a hantavirus outbreak before it got marooned off the coast of Cabo Verde, to prevent further spread of the disease. Three people – a Dutch couple and a German national – died in the outbreak on the MV Hondius. Eight ‌people, including a Swiss citizen, were suspected to have contracted the virus, according to the World Health Organization. The vessel’s operator, Oceanwide Expeditions, said 29 passengers.
