The World Health Organization (WHO) confirmed on Wednesday that the variant responsible for the hantavirus outbreak aboard polar cruise ship MV Hondius is the Andes virus, the only documented strain capable of human-to-human transmission, raised the total number of linked cases to eight, and launched the international tracing of 23 passengers who left the ship two weeks ago during a stop at the island of Saint Helena. The confirmation of the strain represents a significant epidemiological development and substantially widens the scope of the health investigation.
