今天的支那毒也起源于支那啊

至少极大概率源于支那，并且郑和把支那病毒带到了东南亚

According to a team of medical geneticists led by Mark Achtman that analysed the genetic variation of the bacterium, Yersinia pestis "evolved in or near China" over 2,600 years ago.[62][63][64] Later research by a team led by Galina Eroshenko places the origins more specifically in the Tian Shan mountains on the border between Kyrgyzstan and China.[65][66] However more recent research notes that the previous sampling had a very heavy East Asian bias and that sampling since then has discovered strains of Y. pestis in the Caucasus region that were previously thought to be restricted to China.[67] There is also no physical or specific textual evidence of the Black Death in 14th century China. As a result, China's place in the sequence of the plague's spread is still debated to this day.[68] According to Charles Creighton, records of epidemics in 14th century China suggest nothing more than typhus and major Chinese outbreaks of epidemic disease post-date the European epidemic by several years.[69] The earliest Chinese descriptions of the bubonic plague do not appear until the 1640s.[70]Nestorian graves dating to 1338–1339 near Issyk-Kul in Kyrgyzstan have inscriptions referring to plague, which has led some historians and epidemiologists to think they mark the outbreak of the epidemic. Others still favour an origin in China[66] or even Kurdistan and not Central Asia. According to the theory of Chinese origin, the disease may have travelled along the Silk Road with Mongol armies and traders, or it could have arrived via ship,[68] but this theory is still contested. According to John Norris, evidence from Issyk-Kul indicates a small sporadic outbreak characteristic of transmission from rodents to humans with no wide-scale impact.[70] Epidemics killed an estimated 25 million across Asia during the fifteen years before the Black Death reached Constantinople in 1347.[71][72] According to Achtman, the dating of the plague suggests that it was not carried along the Silk Road, and its appearance in that region probably postdates the European outbreak.[68] There are no records of the symptoms of the Black Death from Mongol sources or writings from travelers east of the Black Sea prior to the Crimean outbreak in 1346. The Silk Road had already been heavily disrupted before the spread of the Black Death. Western and Middle Eastern traders found it difficult to trade on the Silk Road by 1325 and impossible by 1340, making spread of the plague less likely.[70] It is speculated that rats aboard Zheng He's ships in the 15th century may have carried the plague to Southeast Asia, India, and Africa.[68]
