Chinatowns are enclaves of Chinese people outside of China. The first Chinatown in the United States was San Francisco's Chinatown in 1848, and many other Chinatowns were established in the 19th century by the Chinese diaspora on the West Coast. By 1875, Chinatowns had emerged in eastern cities such as New York City, Boston, Pittsburgh, and Philadelphia. The Chinese Exclusion Act of 1882 barred Chinese immigration to the United States, but the Magnuson Act of 1943 repealed it, and the population of Chinatowns began to rise again.
The San Francisco plague of 1900–1904 was an epidemic of bubonic plague centered on San Francisco's Chinatown. It was the first plague epidemic in the continental United States. The epidemic was recognized by medical authorities in March 1900, but its existence was denied for more than two years by California's Republican governor Henry Gage. His denial was based on business reasons, to protect the reputations of San Francisco and California and to prevent the loss of revenue due to quarantine. The failure to act quickly may have allowed the disease to establish itself among local animal populations. Federal authorities worked to prove that there was a major health problem, and they isolated the affected area; this undermined Gage's credibility, and he lost the governorship in the 1902 elections. The new governor, George Pardee, implemented public-health measures and the epidemic was stopped in 1904. There were 121 cases identified, resulting in 119 deaths.
