The flu didn’t “disappear”; it was unable to effectively transmit in an environment where everyone was taking extreme precautions to avoid spreading a respiratory infection. Influenza spreads similar to how COVID-19 does, but the rate of spread (R0) is far lower (about 0.9-1.3 for seasonal flu vs 4.5-5.3 for the latest COVID-19 variants).
Between the masks, social distancing, lack of large gatherings, lack of widespread travel, significant increase in hand washing, etc. flu didn’t stand much of a chance. That said, there were still over 1,700 cases of flu this past season (Sept 2020- Apr 2021). Over 800,000 flu tests were performed during that time.
I hate to break it to ya but you are swallowing a whole load of crap. There is no way mask wearing and hand washing stopped the flu but allowed covid to spread. Thousands die every year in the US from the flu and suddenly no one dies of flu but everyone dies of covid. Put your thinking cap on man!
Here in Texas we had a "massive outbreak" of this highly contagious 5.0 on the fujita scale covid 19 in El Paso. It was so bad hospitals were on the verge of collapse (whatever that means) and they were setting up triage tents (never used of course because it was for show) in the parking lots.
So apply a little logic here. El Paso is one of the most visited cities in Texas. Many many thousands of people travel in and out of El Paso and back to other parts of Texas every single day. This never stopped during this supposed massive covid outbreak. People continued to go in and out of El Paso every day by the thousands. So ask yourself with covid transmitting so easily (much easier than the flu according to you) how did this massive outbreak manage to contain itself to El Paso? Why didn't the thousands of people going in and out of that city every day spread this disease?
The answer is obvious. El Paso is a corrupt city and the hospitals there were using covid to collect massive amounts of federal money. There was no massive outbreak and the hospitals were not over run. No one ever used the tents in the parking lots because it was just theater.
Like global warming covid is a huge scam. Fall for it and you will end up living in a socialist hell hole.
