For those who enjoy stats, like my family, a few things come to mind. I hear more about COVID with travelers than folks in my community. However, I'm planning a couple trips so I'm on a few forums so I "communicate" more with travelers than I do with people in my community. I've been hearing about people arriving to Hawaii and New Zealand and very soon after arrival developing COVID symptoms. Also, seems like I'm hearing that many travelers to Europe are coming down with COVID, with more seeming to contract it in Europe or on the way home. For me, I "mix" with people more when I travel, so that is certainly a factor. Also, it would be interesting to know what strains people are getting when they travel. I was freshly boosted prior to my trip to Europe but the new booster had not yet been released.
I'm a firm believer in hand washing. I had a heavily bandaged hand for most of my trip. It was impossible to wash thoroughly unless I wanted to rewrap the hand. Obviously, it is impossible to know how I contracted COVID, but there were factors that likely increased my chances of getting it.
Personally, for me the "take away" is that COVID is certainly out and about, and so without becoming a fanatic, I will do what I can to avoid it. I'll be freshly boosted prior to our trip to New Zealand the end of January. I feel the vaccine is our biggest "weapon". I will do what I can to start my trip with a strong immune system like being well rested. I will again mask in the airports and public transportation. I mask on planes when I'm not actively eating and drinking.
I can really only control my own behavior, but I hope the reaction to these cases influences people to get the boosters and be vigilant within reason as opposed to ignoring the existence of COVID.
