SARS-CoV-2 Coronavirus (COVID-19)

COVID, as it relates, closed itself out.

 

The Spanish flu of 1918 killed millions, but now, over a century later, it's nothing to be feared. This is because the virus has evolved into a milder form, which rarely kills the host. This is a normal course of evolution, because a virus that kills its host is at a disadvantage; a form that reproduces in the host without killing it or making it sick is favored by natural selection, and eventually supplants the more deadly strains. This is what was predicted by experts, and it has mostly come to pass.

Of course the deadly strains still exist, and will continue to cause illness and death until they are eradicated by quarantine and vaccines, but they are becoming rarer and rarer.

No one can predict how deadly a strain of virus can be; it's really just an unlucky accident. It may be fairly benign in the original host, but when it crosses over to humans, it's much more deadly.

Although covid was briefly the largest cause of deaths, it has long since faded into the background. Unfortunately, the deadly strains will be with us for much longer than necessary due to the hysteria of anti-vaccination idiots.
