4 evolutionary scenarios for the coronavirus that causes Covid-19 – STAT:

In the ongoing struggle of SARS-CoV-2’s genes versus our wits, the virus that causes Covid-19 relentlessly probes human defenses with new genetic gambits. New variants of this coronavirus with increasing transmissibility have sprung up every few months, a scenario that is likely to continue.

Some experts believe that the pandemic appears to be on an evolutionary slide toward becoming endemic, a “new normal” in which humans and the virus co-exist, as we currently do with influenza. But coronaviruses are clever. While an endemic resolution may be in sight, SARS-CoV-2 could still shock the human species with a devastating evolutionary leap.

Here are four possible scenarios, each taken directly from the known evolutionary playbook of coronaviruses.
