No, covid isn't going away. It's adapting to us. It's more infectious and it's also getting round the vaccinations - the Omicron variant has 32 mutations to its spike protein which is the main way the vaccines fight the virus. We don't know anything about Omicron and long covid - it hasn't been around long enough.
Denial is exactly the way America reacted to the 1918 flu. The disease lasted for about 3-4 years before it mutated enough to live with us without killing too many of us.
The last time a coronavirus broke out was probably in 1889, the one known as Russian flu. The symptoms are more similar to covid and most of the victims were older.
That one's still with us - as a cold germ, not a pandemic. Eventually covid will settle down too.
