In order to believe covid exists we have to first believe the flu somehow disappeared.
Millions saw the Apollo missions with their own eyes. How many people have seen this virus?
I’ve had the flu many times.
This, clearly, wasn’t the flu.
Millions have had it. There’s more senses than just sight.
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.
