Resort Bubble?

[HI_Someday]

...Store employees don't want to spread the virus to friends and family.  If they're sick, they'll stay home (I think).  Tourists, with a lot of money invested in their little bubble vacations, are not going to let a little sore throat keep them from going on their Hawaiian adventure.

I don't understand how people can continue to think like this. You can have the virus and not have any symptoms, that is you won't feel sick or have a sore throat, and still pass the virus on to others. Asymptomatic. It's a thing.
