A hantavirus outbreak tied to an Antarctic cruise ship has left 41 people under monitoring in the United States, but federal health officials say the risk to the public remains 'very low.'
The concern centres on the Andes virus, a rare hantavirus strain capable of limited person-to-person spread. Most of those being monitored were passengers aboard the MV Hondius expedition cruise, where several illnesses and deaths were reported after the ship returned from South America.
