TL;DR: The cruise ship outbreak is of type Andes Virus (ANDV) which is a subtype of Hantavirus. It has some special enhancements like human to human transmission or 20-40 % fatality. You could very well be infectious even though asymptomatic. COVID-Style pandemics unlikely, though, as transmittability is not high enough for a full pandemic. Outbreaks evidently very possible. If you have possibly been exposed, isolate and seek medical support…
Tldr? It’s hard to read on mobile.

Sounds pretty spot on to me based on what I’ve been hearing.
