A hantavirus outbreak is one of the latest health crises tied to cruise ships, but experts say travelers don't have new cause for concern.

A deadly outbreak of the rare hantavirus unfolded over the course of weeks on a cruise ship that sailed from Argentina toward Antarctica and then across the Atlantic Ocean as passengers and crew members fell sick.

The professor said a close look needs to be taken at what happened and what went wrong. “We need total rethinking,” she said.

A Bay Area resident who was exposed to Andes hantavirus on a cruise ship is back home, public health officials confirmed Sunday. The individual was on board the MV Hondius but departed before health officials determined a passenger’s death was due to hantavirus.

Once the MV Hondius anchored near Tenerife, passengers started disembarking in small groups to begin their quarantines.
