@Suzy4242 @WendyOrent @amybarnhorst TB is ongoing, though no longer considered pandemic in HIC, but was pandemic for most of the 19th century at least. Here is genetic evidence of a coronavirus epidemic that lasted 20000 years until people evolved immunity over many generations.

@Suzy4242@WendyOrent@amybarnhorst结核病仍在继续，尽管在HIC中不再被视为大流行，但至少在19世纪的大部分时间里都是大流行。这是一种冠状病毒流行病的遗传证据，这种流行病持续了2万年，直到人们在几代人的时间里进化出免疫力。
