Three passengers were hoisted from a luxury cruise ship this week as a hantavirus outbreak turned a vacation into a floating quarantine. The World Health Organization confirmed the evacuations and warned that the virus may have achieved the terrifying milestone of human-to-human transmission. According to health officials, the ship is now a laboratory of "engineered thirst" and medical anxiety. While the cruise was marketed as a haven of cocktails and calm, the reality is now a physical scene of bio-suits and fever charts. Per the WHO report, the suspicion of transmission among passengers has sent health agencies into a frenzy. It is the ultimate nightmare for the vacationing class: a five-star cabin that doubles as a isolation ward.
