I think COVID-19 is here to stay. There are reports of Chinese previously infected and turning negative are now turning positive.
The virus will wipe out the weakest and the strongest will survive.(We might be experiencing waves of deaths now because humans are coming in contact with it and only the strongest will survive) Just like other flu, strong bodies will find a way to fight it. People will still die of COVID-19 in the coming years just like some people die as a result of the normal flu.
Scientists might find solutions-like anti-malarial drugs-to mitigate it for few days but the cycle of getting infected will continue. At the end of the day, the virus will just be like any other flu.
Any other flu does not routinely cause interstitial pneumonia
Inaitwa herd immunity.
