There are lots of discussions going on with respect to what exactly happened to the flu this year. It was certainly expected that the social distancing and masking would have an effect, and that numbers would be lower… but nobody really expected it to be virtually zero. The number of pediatric flu deaths in the U.S. this season was exactly one (where it’s normally in the hundreds), and you can be sure that unfortunate kid caught it from a foreign traveller.
How do I know that? Because the flu, like C19, is a virus… and viruses need a breeding population of hosts that they can infect.
Unfortunate side-note for those of you who want to believe in Bigfoot or the Yeti or the Loch Ness Monster or the Ogopogo; perhaps the biggest show-stopper in there being a possibility of them existing is that you can’t have just one. You’d need a breeding population, and it’d have to be significant enough to perpetuate the species. They’d take up a lot of space, and there would be ample evidence (droppings, dwellings) to find, even if not the creatures themselves, whether on land or in the water. It’s not like “I saw *the* Ogopogo”; Lake Okanogan would have to have been teeming with them for centuries.
The masking, and sanitizing surfaces every 10 minutes, had a drastic effect. Flu probably arrived in North America on various airplanes, but died out with nowhere to go. No breeding population of hosts. In fact, so drastic was its demise that there are two common flu strains that may well be extinct. Around the world, there were zero cases reported of two particularly common strains; two that are always part of the annual flu-vaccine concoction. That, on its own, doesn’t yet mean they’re gone forever… but if they don’t show up next year or the year after that… well, it’s a virus. Unlike 200 BigFoots (Bigfeet?) that might be hiding in a cave somewhere in Sasquatch Park, there’s no hiding place for a virus. When the last one has no place to go, it’s gone forever.
It’s ironic that a couple of flu strains might be eradicated simply as “collateral damage”… while C19, with its variety of variants, is going to be around for a lot longer.
The bigger irony would be that Bigfoot actually exists… but gets wiped out by C19, because the humans were unable to eradicate it.
