What happened

The ‘concerning’ truth about the hantavirus cruise outbreak — and how long passengers may actually need to isolate A hantavirus outbreak aboard the MV Hondius cruise ship has killed three passengers and sickened at least four others, worrying health experts.

Why it matters

People most often contract the rare but deadly disease from the feces, urine or saliva of infected rodents, but the World Health Organization insisted Tuesday that no rodents have been found on the liner.

Common ground

Now, scientists are looking at one particularly worrisome potential cause of transmission.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
