Normally a virus doesn't spread well if it's lethal, because the person dies before they can infect many others. 'Stealth' infections like Covid-19 are super smart, they allow the person to be healthy for weeks, happily infecting others, before they hit hard. My prediction of the virus suddenly just disappearing is not because it may become less virulent. It may just get out-competed by other microbes and go into dormancy. The even more sneaky lethal infections not mentioned here are chronic infections. Ones that live in you sometimes your entire life. They may be responsible for most of our chronic diseases, diseases we blame on things like diet, or genetics. STIs are often like this. https://aeon.co/essays/the-most-dangerous-pathogens-in-human-history-have-moved-by-stealth?fbclid=IwAR2zEDXgcslx_1ttCm7YutJD2moss3yAeGmlxEgRG6q-8_tAjRoxVCcBmCg
