Couple things.
First, I wouldn't have even started my trip if I knew there was something outside of my control (that I was expressly warned about) that would keep me from returning. My visit was before mandatory testing, and you bet your rear I was super stressed about either getting sick while at Cozumel or becoming asymptomatic and crop dusting thousands of people on my return.
Second, if I did have an advantage over others.... I sure as heck wouldn't flaunt it and say you don't understand why others are so stressed.
