China is the origin of the virus and still accounts for over 80 percent of cases and deaths. But its cases peaked and began ­declining more than a month ago, according to data presented by the Canadian epidemiologist who spearheaded the World Health Organization’s coronavirus mission to China. Fewer than 200 new cases are reported daily, down from a peak of 4,000.

Subsequent countries will follow this same pattern, in what’s called Farr’s Law. First formulated in 1840 and ignored in ­every epidemic hysteria since, the law states that epidemics tend to rise and fall in a roughly symmetrical pattern or bell-shaped curve. AIDS, SARS, Ebola — they all followed that pattern. So does seasonal flu each year.

Clearly, flu is vastly more contagious than the new coronavirus, as the WHO has noted. Consider that the first known coronavirus cases date back to early December, and since then, the virus has ­afflicted fewer people in total than flu does in a few days. Oh, and why are there no flu quarantines? Because it’s so contagious, it would be impossible.
