Petri dishes.
Have been on five cruises and loved them, last was with 50+ others in May 2019.
Will likely wait at least a year on the next, though.

“Petri dishes.”
The analogy is ignorant and getting tiresome. Usually made by those who cannot afford to on one. The CDC will drive the Cruise industry into bankruptcy and it will ruin more people then you can imagine.
The petri dishes are the Wuhan labs.
