Since the pandemic started I have had: 5 trips to WDW. 1 trip to DL. 2 trips to Italy. 1 trip to Istanbul. 1 trip to Alaska. A number of trips to ATL and Wichita. Never contracted COVID.
I have barely been around anyone for these past two weeks -- pretty much have been doing my own thing and working alone in my classroom with it being summer break (teacher here). Symptoms started this past Friday. Tested positive Saturday (yesterday). I'm still trying to rack my brain as to exactly when/where I was exposed.
You can do everything right and catch it. You can disregard all safety protocols and never catch it. I observed every safety precaution and was very lucky not to come home with COVID on any of my trips. But that's all they are -- precautions. They are not guarantees, but you have to do what is best for you!
Well, DH and I both avoided Covid until one of us got it yesterday....had two trips canceled on us, canceled another on our own, but finally decided to take a trip last week to Los Cabos Mexico. We got our second booster a few weeks before the trip. We were in the very tiny minority of people in Newark, Dallas and San Jose Del Cabo airports wearing masks. We wore KN95s for the entire time. We managed to get to our resort in Mexico and had a great time. Eight days/nights in paradise. We chose this resort because all of the dining options are outside. Entrance to the room is from the outside as well. We spent time outside at the pool all week. We had a long couples massage scheduled...and we moved it to a private outdoor cabana on the beach to avoid indoors. Our massage therapists wore KN95s, even though we just had cloth around three sides of the cabana...and a nice breeze. Had an amazing trip....but....
We headed back on Friday, home very late on that night. Again, were in the less than 5% of travelers masked. And on Saturday morning my husband woke up...scratchy throat, achy, and yup...sure enough he tested positive. So far, I'm negative and have no symptoms. If he got it...as careful as we were, lots and lots of people are in for it this summer. My husband is doing well...he has a cough that is definitely a chest cough, low fever, some chills and achy....but our doc said the second booster is definitely helping in diminishing his symptoms. His appetite is normal....he even had a glass of wine last night while we watched a movie.
Based on the 3-4 day incubation period for Omicron Ba5, the doctor is pretty sure he got it in Mexico. DH did not see another man in the only public bathroom we used all week...at .the pool. We had many outdoor conversations with unmasked pool servers/attendants and restaurant servers, but figured outside was safe for that. Anyone in our room to clean...do turn-down service...etc, were all masked. Whenever we came back into our room, we opened the wall of sliding glass doors to air it out and turned the overhead fan on. And so, like you....we have literally no idea where he got it. But...as I said, I expect there is a ton of virus out there. My husband's home test is not reported...like millions of others.
We're so glad that we took the trip, and very thankful that he didn't get it until after we were home. His cough is nasty enough that there's no way we could have gone to the pool or enjoyed meals at the restaurants....it would have definitely been room service in our room, or on the balcony.
I'm not masking inside with him...I've been around him all of the days he was likely pre-symptomatic. We drove home in our car from the airport....slept in our bed on Friday night. I'm almost just wanting to get it....get it over with for now. I don't see the point in trying to fight it anymore.
We did several indoor meals, however.
