> Plague is a globally distributed, zoonotic disease caused by the bacterium Yersinia pestis. In the late 1890s, rat-infested steamships introduced the disease into the continental United States. The first documented autochthonous human infection occurred in the Chinatown section of San Francisco, California, in March of 1900. Cases were soon reported in other port cities, including New Orleans, Galveston, Seattle, and Los Angeles. Along the Pacific Coast, infection spread from urban rats to native rodent species, and by the 1950s, Y. pestis had spread eastward to reach western portions of the Dakotas, Nebraska, Kansas, Oklahoma, and Texas. This distribution has remained static for >60 years, presumably the result of climatic and ecologic factors that limit further spread. Although poorly defined, these factors may be related to the ecology of vector species rather than that of rodent hosts.

Nope. Sorry. I like my... um... theory? yeah. Theory, that’s the ticket!! I like my ‘theory’ better. It’s truthy and truthy or truthish is the new scientific bar. Just ask any media popular climate scientist!
China discovered and invented America because plague!
So let it be written. So let it be said.
