There is an absolute nightmare developing on a cruise ship stuck at sea! What was supposed to be a weekslong polar cruise from Argentina to Antarctica has resulted in fear and chaos after a suspected deadly hantavirus outbreak! And it's really bad, y'all! If you don't know, hantavirus is a rare and very dangerous disease typically spread through infected rodent droppings or urine. It can cause severe respiratory illness. While early treatment can improve survival odds, there is no cure.
