Asia faces low hantavirus risk as Singapore isolates 2 from cruise over cases

Health experts assess the risk of a hantavirus outbreak in Asia as minimal, despite two Singapore residents being isolated upon returning from a cruise ship where three individuals died from the virus. Hantaviruses, carried by rats, can infect humans through direct exposure, with human-to-human transmission being exceptionally rare. The disease, named after the Hantan River in South Korea where an early strain was identified, can have an incubation period of several weeks before symptoms manifest and lead to severe illness. The isolation of the two Singapore residents follows the deaths on the cruise ship, which had previously caused regional concern.
