Quarantine & Eradication: Bubonic Plague in San Francisco



From now through September 15, the San Francisco History Center is hosting an exhibition documenting the bubonic plague in San Francisco. The exhibit, Quarantine & Eradication: Plague in San Francisco, highlights how San Francisco reacted and responded to the bubonic plague outbreaks in 1900 and in 1907.

At the exhibit, one will see a variety of documents, photographs, scrapbooks, and other physical items from the San Francisco History Center’s collections. The sources provide fascinating accounts of the hysteria and racial discrimination surrounding the first plague outbreak in 1900 in Chinatown juxtaposed with the eradication campaign with the second plague outbreak in 1907.

This blog post will focus on the first outbreak in Chinatown. There will be a second post that focuses on the second outbreak in 1907. When the first bubonic plague case was found in San Francisco, there were mixed reactions - including denial and calling it the "fake plague."

Definition of bubonic plague:

Bubonic plague is a disease caused by the bacillus Yersinia pestis. It is characterized by painfully swollen lymph nodes or "buboes." In some cases, the bacilli enter the bloodstream, resulting in a condition known as "septicemic plague." A third form, "pneumonic plague," affects the lungs. All three types may produce internal bleeding and the formation of large bruises on the skin, hence another name for the plague, "the black death." All three forms are usually fatal if not properly treated. Septicemic plague usually results in death within 24 hours, while the other two types generally kill those afflicted in 3 to 4 days after infection. The bacillus is carried by fleas that live off the blood of many kinds of rodents. Contagion with bacillus appears to have been a permanent feature of rodent colonies in the Himalayan borderlands between India and China. Similar colonies were also found in central Africa. In these places local people seem to have learned to avoid contact with rodents; consequently, plague did not reach epidemic proportions. This situation began to change in the 13th century, when much of Central Asia was conquered by the Mongols, who then extended their domain westward towards Europe and southward into China. The military and economic expansion of the Mongol Empire was accompanied by the movement of the rat population into new areas. At about this time, the intensification of commercial navigation also opened up new routes for the movement of infected rats into Europe and the Middle East.
 

In 1894, Yersinia pestis was identified as the cause of plague, and in the 1920s researchers in Manchuria discovered the role of rodents in harboring it. In the 1930s, the recently discovered sulfa drugs finally offered something close to a cure for plague, and from the 1940s onwards, antibiotics provided a complete cure. Even so, the disease has not been eradicated; minor outbreaks of plague still occur in many parts of the world, including the western United States.
