Anything is possible, even that the corona virus will become much less virulent soon.
I have mentioned it before, but will gladly say it again. The Spanish flu swept through the world in 1918 and 1919, killing millions, literally more people than had died in the first World War, then it disappeared. The virus still exists, but has not caused outbreaks since 1919.
It is difficult to prove, historic sources being what they are, but syphilis seems to have reached epidemic proportions when introduced to Europe at the start of the 16th century then settled down as a nasty and contagious disease, but not an epidemic.
Similarly, Europe suffered various outbreaks of bubonic plague - the first one killing, as far as we know, an average of every third person in Europe. Subsequent outbreaks killed fewer, but still horrifying numbers. Since around 1700 there have been no large outbreaks recorded.
The sweating sickness (sudor angelicus) afflicted England and the geographic England only at regular intervals during the 1500s- Henry VIII would never have married Katherine of Aragon if the sweating sickness had not killed his brother. Anne Boleyn survived it - at the time many felt it would have been better if she hadn't, but try imagining history without Elizabeth Tudor! No-one has suffered the sweating sickness since somewhere around 1600 as it is not identical with any known strain of influenza.
So the corona virus may just disappear too.
