黑死病

The origin dates to 1565, during the reign of Maha Chakkraphat (husband of courageous elephant-battling Queen Suriyothai), when there was a plague in the old royal capital. The tropical malady was blamed on seafaring Portuguese and Persian traders, who sailed with the sickness upriver to the old capital. As far as public-health crises go, it was much worse, and way weirder, than is reported in the history books.
