WASHINGTON, May 18 (Reuters) – An adult in Colorado has died after a confirmed case of hantavirus ​that is not linked to ‌a recent outbreak aboard a cruise ship in the Atlantic, Colorado Department of Public Health and Environment officials said in ‌a ​statement on Monday.

The strain ⁠of hantavirus that ⁠caused the Colorado death occurs regularly in Colorado at this time of year, the statement said, and ​officials are investigating the source of exposure.

Hantavirus is primarily spread by ⁠rodents but can ⁠be transmitted between people in ​rare cases and after prolonged, close ​contact. Incubation can last about six ‌weeks.

The Dutch-flagged MV Hondius cruise docked at Rotterdam on Monday. It had been carrying around 150 passengers ⁠and crew from 23 countries when a cluster of severe respiratory illnesses was first ⁠reported to ‌the World Health Organization ⁠on May 2.

Three people on ​the ‌liner have died. Including ​those deaths, ⁠there have been eight confirmed and two probable cases on board, according to WHO.
