Earlier today I spoke with the doctor on the ship and he confirmed something. CDC messaging continues to say "prolonged, close contact" but that contradicts: 1) what's in the literature, and 2) what's happening on this ship.
--> the doc told me a few who got infected/died DID have direct contact w/ very sick patient while treating them, but 3 who tested positive did NOT have direct physical or close contact - only shared time in a few spaces on the ship where people congregate (dining, lecture area)
"close, prolonged contact" doesn't strike me as correct
