Like Covid, the black death came from China. Sorry to say, but China is a cesspool of filth. Always has been.
Yep. Bubonic Plague, various types of influenza, COVID and
many sorts of animal diseases come from China.
My father was in China during WWII. He said it was the
filthiest place he ever seen, along with India.
Because of his experiences there he never ate Chinese food
or entered a Chinese restaurants til the day he died.
After the war my father worked at Walter Reed in the vaccine
division. He knew something about infectious diseases.
