CV and mad panic behaviour

Correct me if I’m wrong, the only way a population can gain a natural immunity to a disease is for those who are susceptible to it to die from it or at least be rendered infertile. Then natural selection will enable those who are genetically resistant to it become dominant. That would take a long time to play out and the mass deaths would be legendary.

The other way is for the population to be widely exposed to a disease and develop an immunity that might in some cases be life-long. But leaving aside the messy theory about epigenetics, that immunity wouldn’t be passed on to the next generation as there’d be no genetic change or mutation. This was historically the way Europeans were able to survive smallpox and then use it against indigenous populations in the Americas as a biological weapon. Children who were infected with smallpox wouldn’t become very sick and they’d be immune for life.

But if the latter method had caused Indians to develop widespread immunity that predated Covid-19, that means Covid-19 was circulating in India well before it escaped from Wuhan. If this were even a possibility, the Chinese would have been yelling it from the rooftops. As they haven’t, we can stick a fork in that idea.
