The '''San Francisco plague of 1900–1904''' was an epidemic of [[bubonic plague]] centered on [[San Francisco]]'s [[Chinatown (San Francisco)|Chinatown]]. It was the first such plague in the continental United States.<ref>{{cite journal |last=Anderson |first=Elizabeth T. |month=May–June |year=1978 |title=Plague in the Continental United States, 1900–76 |journal=Public Health Reports |volume=93 |issue=3 |pages=297–301 |url=http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1431896/pdf/pubhealthrep00142-0091.pdf}}</ref> Discovered by medical authorities in March 1900, the existence of the epidemic was denied for more than two years by the governor of California, [[Henry Gage]]. The denial was based on business reasons: the wish to keep the reputations of San Francisco and California clean and to prevent the loss of revenue from trade stopped by [[quarantine]].

Proof that an epidemic was occurring served to undermine the credibility of Gage, and he lost the governorship in the 1902 elections.

==Background==
{{Main|Third plague pandemic}}
The third pandemic of the plague started in 1855 in China and eventually killed about 15 million people, mainly in India. In 1894, the plague hit [[Hong Kong]], a major trade port between China and the US.<ref name=Echenberg6>Echenberg 2007, p. 6</ref><ref>{{cite journal |last=Haas |first=Victor H. |date=March 1959 |title=When Bubonic Plague Came to Chinatown |journal=The American Journal of Tropical Medicine and Hygiene |volume=8 |issue=2 |pages=141–147 |doi=10.4269/ajtmh.1959.8.141 |pmid=13637311 }}</ref> US officials were rightly worried aboutthat infectionothers fromwould peopleget andinfections from cargo carried by ships crossingthat would cross the Pacific Ocean,. andFor allthese suchreasons, all ships were rigorously inspected. At thisthat time, however, it was not widely known that rats could carry plague germs, and that fleas on those rats could transmit the disease to humans.<ref name=Echenberg7>Echenberg 2007, p. 7</ref> Ships arriving in US ports were declared clean after inspection of the passengers showed no signsigns of disease.

[[Kitasato Shibasaburō]] first described the plague bacteria in Hong Kong in 1894. Simultaneously but independently, [[Alexandre Yersin]] described and named the [[Yersinia pestis|plague bacterium]], and proved the rat to be a major vector in plague. Masanori Ogata and [[Paul-Louis Simond]], acting independently, proved the flea was a critical link in 1897. The same year, [[Waldemar Haffkine]] developed a vaccine to inoculate humans against the disease. These advancements were discussed in 1897 at medical conferences, but many doctors continued with their previous and outdated methods of dealing with the disease.</ref>
 
In November 1898, the US [[Marine Hospital Service]] (MHS) chief surgeon, James M. Gassaway, felt obliged to refute rumors of plague in San Francisco. Supported by the city's health officer, Gassaway said that some Chinese residents had died of pneumonia or lung edema, and it was not bubonic plague.<ref>{{cite journal |last=Gassaway |first=James M. |date=November 29, 1898 |title=False report of plague in San Francisco |journal=Public Health Reports |volume=13 |issue=51 |pages=1503 |jstor=41453167}}</ref>
 
[[File:Honolulu Chinatown fire of 1900.jpg|thumb|In January 1900, [[Chinatown, Honolulu|Honolulu's Chinatown]] burned down in an effort to control [[bubonic plague]].]]
In the newly formed US [[Territory of Hawaii]], the city of [[Honolulu]] fell victim to the plague in December 1899. Residents of [[Chinatown, Honolulu]], were reporting cases of fever and swollen [[Lymph node|lymph glands]] forming [[bubo]]es, with severe internal organ damage quickly leading to death. Not knowing precisely how to control the spread of the disease, city health officials of the city determineddecided to burn theinfected houses where victims had been found. Thousands of area residents were evacuated and quarantined for four months. Infected buildings were identified and destroyed by fire. On January 20, 1900, changing winds fanned the flames out of control, and nearly all of Chinatown burned—{{convert|38|acre}}—leaving 6,000 without homes.<ref>Chase 2003, p. 12</ref><ref>{{cite book |last=Taylor |first=Albert Pierce |title=Under Hawaiian Skies |url=httphttps://booksarchive.google.comorg/books?id=_2CmsAMr75wC&pg=PA387details/underhawaiiansk00taylgoog |year=1922 |publisher=Advertiser Publishing Company |location=Honolulu |page=[https://archive.org/details/underhawaiiansk00taylgoog/page/n501 387]}}</ref>

The clash between Gage and federal authorities intensified. Wyman instructed Kinyoun to place Chinatown under a second quarantine, as well as blocking all [[East Asians]] from entering state borders. Wyman also instructed Kinyoun to inoculate all persons of Asian heritage in Chinatown, using an experimental [[vaccine]] developed by [[Waldemar Haffkine]], one known to have severe side effects.

Between 1901 and 1902, the plague outbreak continued to worsen. In ana 1901 address to both houses of the [[California State Legislature]], Gage accused federal authorities, particularly Kinyoun, of injecting plague bacteria into [[cadavers]], falsifying evidence.<ref name=Skubik2002>{{cite web |url=http://www.skubik.com/thesis%20summary.pdf |title=Public Health Politics and the San Francisco Plague Epidemic of 1900-19041900–1904 |publisher=Mark Skubik, San Jose State University |year=2002 |accessdateaccess-date=August 19, 2007 |archive-08url=https://web.archive.org/web/20160304000446/http://www.skubik.com/thesis%20summary.pdf |archive-19date=March 4, 2016 |formaturl-status=PDFlive }}</ref> In response to what he said to be massive scaremongering by the MHS, Gage pushed a censorship bill to gag any media reports of plague infection.

== Racism and discrimination lawsuit ==
 
Widespread racism toward [[History of Chinese Americans|Chinese immigrants]] was socially accepted during the initial time of the Chinatown plague in the early 1900s. Standard social rights and privileges were often denied to the Chinese people, as shown in the way landlords would refuse to maintain their own property when renting to Chinese immigrants.<ref name="ReferenceA">{{Cite book|title=Plague, Fear, and Politics in San Francisco's Chinatown|isbn=9781421405100|last1=Risse|first1=Guenter B.|date=March 14, 2012}}</ref> The living conditions in the Chinatown community reflected the social norms and racial inequalities during that time for Chinese immigrants. Housing for the majority of Chinatown Chinese immigrants was not fit nor adequate for human living, but with scarce housing options and landlords unwilling to provide equal and fair housing, Chinese immigrants were left little option other than to live with such housing disparities.<ref name="ReferenceA"/> Discrimination against Chinese Americans culminated in two acts, the quarantine of San Francisco's Chinatown, and the permanent extension of the [[Chinese Exclusion Act]] of 1882.<ref>{{Cite web|url=https://www.nps.gov/parkhistory/online_books/5views/5views3g.htm|title=A History of Chinese Americans in California: THE 1900s|archive-url=https://web.archive.org/web/20180210072505/https://www.nps.gov/parkhistory/online_books/5views/5views3g.htm|archive-date=February 10, 2018|url-status=live}}</ref> The extended quarantine of Chinatown was motivated more by racist images of Chinese Americans as carriers of disease than by actual evidence of the presence of [[Bubonic plague]].<ref>{{Cite web|url=https://www.nps.gov/parkhistory/online_books/5views/5views3g.htm|title=A History of Chinese Americans in California:THE 1900s|archive-url=https://web.archive.org/web/20180210072505/https://www.nps.gov/parkhistory/online_books/5views/5views3g.htm|archive-date=February 10, 2018|url-status=live}}</ref>
 
San Francisco's quarantine measures were explicitly discriminatory and segregatory, allowing European Americans to leave the affected area, but Chinese and Japanese Americans required a health certificate to leave the city. Residents were initially angered as those with jobs outside of San Francisco were prevented from working. Few Chinese agreed to take the inoculation, especially after press reports on May 22, 1900, that people who did agree were experiencing severe pain from the untested vaccine. On May 24, 1900, with the help of [[Chinese Six Companies]], they hired the law firm of Reddy, Campbell, and Metson. Defendants included [[Joseph J. Kinyoun]] and all of the members of the San Francisco Board of Health. The Chinese wanted the courts to issue a provisional injunction to enforce what they argued was their constitutional right to travel outside of San Francisco. On July 3, 1900, Judge [[William W. Morrow]] ruled that the defendants were violating the plaintiffs' [[Fourteenth Amendment to the United States Constitution|Fourteenth Amendment]] rights. The ruling required that the same restrictions, if any, be applied to everyone no matter their ethnic group. The defendants did not have enough evidence to prove that the Chinese were transmitting the plague. Morrow agreed with the argument that if they were, the city would not have permitted them to roam the streets of San Francisco.<ref>{{cite book|last1=McClain|first1=C.J.|title=In Search of Equality: The Chinese Struggle against Discrimination in Nineteenth-Century America|date=1994|isbn=9780520205147|pages=385}}</ref>
 
The Board then "attempted to sidestep the decision by instituting a quarantine order that avoided mention of race, but which was precisely drafted so as to encompass all of the Chinatown area of San Francisco while excluding white-owned businesses on the periphery of that area"; this effort was also struck down, with the court noting that the boundaries of the quarantine corresponded with the ethnicity of building occupants rather than the presence of the disease.<ref>Brian Dean Abramson, ''Vaccine, Vaccination, and Immunization Law'' (Bloomberg Law, 2019), 6–8.</ref>
 
==Detailed history==
 
===1900===
 
Upon the death of Wong Chut King, the San Francisco Health Board took immediate action to prevent the spread of plague: Chinatown was quarantined.<ref name="The Johns Hopkins University Press">{{cite book|last1=Risse|first1=Guenter B.|title=Plague, fear, and politics in San Francisco's Chinatown|date=2012|publisher=The Johns Hopkins University Press|location=Baltimore|isbn=978-1-4214-0510-0}}</ref> Health officials, in order to prevent the propagation of the disease, made the decision of placing [[Chinatown, San Francisco|Chinatown]] under quarantine, without any notice to the residents&nbsp;– targeting Chinese residents only. White Americans that were walking the streets of Chinatown were allowed to leave; everybody else was forced to stay.<ref name="The Johns Hopkins University Press"/> Physicians were restricted from crossing into [[Chinatown, San Francisco|Chinatown]] to identify and help the sick. The Health Board had to approve whether or not any health official crossed into the quarantined area.<ref name="The Johns Hopkins University Press"/> Due to lack of evidence that the cause of death of King was plague, the quarantine was removed the day after to avoid controversy.<ref name="The Johns Hopkins University Press"/>
 
Kinyoun's lab confirmed the disease was bubonic plague and informed the Health Board right away. In an attempt to avoid a second controversial quarantine, the Health Board continued with a house-to-house inspection to look for possible plague infested households – disinfecting those that were thought to be at risk of infection.<ref name="The Johns Hopkins University Press"/> Participants in the house-to-house examination were mainly volunteer physicians and residents. On the contrary, other residents did not support the inspection and argued that the disinfecting plan was not being done in good faith. Believing a second quarantine would be soon implemented, worried residents began to flee quietly and hide in friends' houses outside of [[Chinatown, San Francisco|Chinatown]].<ref name="The Johns Hopkins University Press"/>
 
As days passed, more dead bodies were reported and autopsies revealed the presence of plague bacilli, indicating that a plague epidemic had hit San Francisco's Chinatown, but the health board still was trying to deny it. The health board attempted to keep all the information regarding the outbreak secret by implementing strict regulations of what physicians could write official death certificates.<ref name="The Johns Hopkins University Press" /> Nevertheless, newspapers published the news of the presence of bubonic plague in San Francisco to the entire nation, especially [[William Randolph Hearst]]'s ''[[New York Journal]]'' which published a special plague edition.<ref>Risse 2012, p. 118</ref>
 
The official inspection and disinfection of Chinatown finally began, thanks to the monetary contributions of the supervisors of the volunteer physicians, policemen, and inspectors that participated in the actual disinfection campaign. The sanitizing of Chinatown began to show results as the death toll slowly dropped throughout the month of March and the beginning of April.<ref name="The Johns Hopkins University Press" /> Towards the end of April, the corpse of Law An, a Chinese laborer from a village near the [[Sacramento River]], was found in an alley in Chinatown. The cause of death of Law An was determined to be bubonic plague. After that, a few more Chinese residents that died suddenly were determined to be infested with plague bacilli. The fear that the bubonic plague was spreading intensified.<ref name="The Johns Hopkins University Press" />
 
The controversy of the vaccination program organized by Kinyoun with the help of Surgeon General Wyman spiked. The plan was to inoculate the Chinese residents with [[Waldemar Haffkine|Haffkine's vaccine]], a prophylactic anti-plague vaccine that was intended to provide some protection against the plague for a 6-month period. No one spoke about the side effects and that the vaccine was still not approved for humans.<ref name="The Johns Hopkins University Press" /> Most Chinese residents refused and demanded the vaccine to be tested in rats first. At first, representatives of the Chinese community had agreed that inoculating the population with such serum could be a reasonable and safe solution, but soon after agreed with the rest of the Chinese population in that it was not ethical to try the vaccine in humans first. The representatives from the [[Chinese Consolidated Benevolent Association|Chinese Six companies]] demanded the vaccination program to be eliminated as an option, and with much pressure and insistence from the Chinese community the vaccination program was halted.<ref name="The Johns Hopkins University Press" />
 
===1901===
 
[[Joseph J. Kinyoun]] was feeling the pressure of the public to clear his reputation. He summoned the help of U.S. Surgeon General [[Walter Wyman]] to bring someone from the outside to investigate Kinyoun's procedures. In December 1900 Wyman selected Assistant Surgeon General Joseph H. White to manage the investigation surrounding all of the Pacific Coast stations. White wanted to focus on how food was handled while being imported from China and Japan. Kinyoun tried to hinder these advances because he did not want to publicly admit that there was an outbreak. White made his appearance in January 1901. White and Kinyoun attended the autopsy of Chun Way Lung who was said to have suffered from gonorrhea. Wilfred Kellogg and Henry Ryfkogel conducted the autopsy and achieved respect from White by revealing that Lung had died from the [[bubonic plague]]. White concluded that Kinyoun's bacteriological confirmation could no longer be credible.<ref name="Risse, Guenter B. 2012 pp. 167-174">1932–, Risse, Guenter B., (2012). Plague, fear, and politics in San Francisco's Chinatown. Baltimore: The Johns Hopkins University Press. pp. 167–174. {{ISBN|9781421405100}}. OCLC 809317536</ref>
 
Governor Gage refused to support the diagnoses that were verified by the competent Pasteurians in San Francisco. Kinyoun was starting to express his frustration and suggested that independent outside experts confirm that the plague was present. White agreed and passed this information to the surgeon general. Kinyoun desired that his reputation be restored and that his findings were valid so that he could continue to investigate plague cases.
On January 26, Flexner, Novy, and Barker arrived in San Francisco. The three scientists were appointed to an official commission to prove if the plague existed.<ref name="Risse, Guenter B. 2012 pp. 167-174"/>
 
Gage reacted by sending a telegram to President [[William McKinley]] urging that the federal experts work with state health authorities. Gage's request was not granted because the federal government wanted the commission to be allowed to work independently. They would relay all of their findings to the treasury department and then forwarded to Gage. Flexner, Novy, and Barker scheduled an inspection of the sick and dead on February 6. The federal investigators split up the duties. Novy carried out bacteriological tests, while Barker accompanied by a Chinese interpreter visited the sick. By February 12, the team had studied six cases that all identified the characteristics of bubonic plague. This was confirmed by pathological and bacteriological data. Flexner, Novy, and Barker completed their investigation on February 16. They met with Governor Gage the same day and informed him of their conclusion.<ref name="Risse, Guenter B. 2012 pp. 167-174"/>
 
Gage was upset and accused them of being a threat to public health. Over the next few weeks Gage questioned the diagnoses and blocked the publication of the final report. He blamed the commission of being biased and influenced by Kinyoun. Finally the two senators for California proposed that Gage needed to engage in friendly cooperation with federal authorities. Gage sent representatives to Washington to reach an agreement for federal authorities to suppress their findings concerning the plague in San Francisco. The federal authorities agreed to these demands after Gage's representatives verbally pledged to manage a sanitary campaign in Chinatown. This would be done secretively under the guidance of an expert from the [[Marine Hospital Service]] This deal was designed to avoid impairing the state's reputation and economy. Surgeon general Wyman took the majority of the blame. He was accused of violating U.S. laws and breaking international agreements that required him to notify all nations that there was an existence of contagious disease. Wyman and President McKinley destroyed the credibility of the American public health in the eyes of the nation and abroad.<ref name="Risse, Guenter B. 2012 pp. 167-174"/>

The state governments of [[Colorado]], [[Texas]] and [[Louisiana]] passedimposed quarantines of California, arguing that since the state had refused to admit to a health crisis within its borders, states receiving rail or shipping cargo from California ports of call had the duty to protect themselves.<ref name=Skubik2002/> Threats of a national quarantine grew.<ref>{{Cite web|url=http://www.digitalhistory.uh.edu/disp_textbook.cfm?smtID=2&psid=3296|title=Migration and Disease|archive-url=https://web.archive.org/web/20171207140513/http://www.digitalhistory.uh.edu/disp_textbook.cfm?smtID=2&psid=3296|archive-date=December 7, 2017|url-status=live}}</ref>
 
As the 1902 general elections approached, members of the [[Southern Pacific supportersTransportation Company|Southern Pacific]] board and the "Railroad Republican" faction<ref>For the "Railroad Republicans", see W. H. Hutchinson, "Prologue to Reform: the California Anti-Railroad Republicans, 1899–1905", ''Southern California Quarterly'' 1962 '''44'''(3): 175–218.</ref> increasingly saw Gage as an embarrassment to state [[United States Republican Party|Republicans]]. Gage's public denials of the plague outbreak were due to protectingprotect the state's economy and the business interests of his political allies.<ref name="Gage denies plague epidemic"/><ref name=Skubik2002/> However, reports from federal agencies and certain newspapers continued to showprove Gage incorrect. Other states were moving to quarantine or [[boycott]] California, and the powerful shipping and rail companies sought a new leader. At the state Republican convention that year, the Railroad Republican faction refused Gage's renomination for the governorship. In his place, former [[Mayor of Oakland]] [[George Pardee]], a German-trained medical physician, received the nomination. Pardee's nomination was largely a compromise between the Railroad Republican factions.<ref>{{Cite web|url=http://governors.library.ca.gov/21-pardee.html|title=George Pardee 1903–1907|archive-url=https://web.archive.org/web/20171207141404/http://governors.library.ca.gov/21-pardee.html|archive-date=December 7, 2017|url-status=live}}</ref>
 
In his final speech, to the California State Legislature, in early January 1903, Gage continued to publicly deny the outbreak,. blamingHe blamed the federal government, in particular, Kinyoun, the MHS, and the San Francisco Board of Health, for damaging the state's economy.<ref name="Gage denies plague epidemic"/><ref name=Skubik2002/>
