Yerba Buena Island (San Francisco Naval Training Station) was identified early in our work as a potential escape community that needed further investigation. After some initial research, it quickly became apparent that the naval station was indeed a provisional escape community, and one that succeeded very well in keeping influenza at bay during the course of the second wave of the 1918–1920 pandemic. Because of its proximity to and usual interaction with the city of San Francisco, and because that city enacted a mandatory face mask law on two occasions during the epidemic, we also collected material on San Francisco.

At a Glance:

  • Type of Site: Naval Base.
  • Population: Approx. 6,000.
  • Pop. Density: 33,103 ppl./sq. mi.
  • Geographical Considerations: Yerba Buena is an island (116 acres) in San Francisco Bay; in 1918, no bridges connected it to land, and boat travel was only means of access.
  • Influenza Cases: 0 during period of protective sequestration; 25 cases after NPI were lifted on 11/21/1918.
  • Influenza Deaths: 0 during period of protective sequestration; 3 from influenza and 2 from pneumonia after that period.
  • First Reported Case: Dec. 6, 1918
  • NPI Implemented: protective sequestration; face masks by medical personnel; daily inspection of sailors; prevention of overcrowding; application of nose and throat sprays; isolation of suspected cases.

Case Study

Historical Background

Yerba Buena, a small island (116 acres) located approximately one mile on either side from the closest points in present-day San Francisco and Oakland, was discovered in 1775 by Spanish explorers entering San Francisco Bay. Finding an abundance of wild mint growing on the island, they named the land Yerba Buena, or “Good Herb.” Use of the island by the U.S. military dates back to 1852, when the government proposed building a line of fortifications in San Francisco Bay to protect northern California and the valuable gold recently discovered there. In 1996, the naval station was decommissioned, but it continues to serve as a U.S. Coast Guard facility and lighthouse.

Located approximately 35 miles away in Vallejo, California, and at the mouth of the Napa River is Mare Island, in reality a peninsula. Originally part of Rancho Soscol, Mare Island was purchased by the U.S. government in 1852 for use as a naval shipyard. In 1854, Mare Island became the first permanent naval station on the Pacific coast. During World War I it operated as a naval yard and dock. Like Yerba Buena/Treasure Island, it was decommissioned in 1996.

The Navy and the Influenza Pandemic

Officials at Yerba Buena Island and Mare Island, and indeed throughout the Navy, were notified of the impending influenza pandemic in early August 1918. On August 9, the Naval Bureau of Medicine and Surgery (BuMed) issued a bulletin that warned of influenza epidemics in Europe and Hawaii and of the likelihood of the disease spreading to the continental United States. Bureau officials advised that no quarantine be instituted, as it was deemed “impracticable,” and warned that “The disease is highly communicable and during epidemics it spreads with remarkable rapidity. Just what conditions are necessary to start one of the periodic world-wide outbreaks is as unknown in this as in other communicable diseases like plague, which are prone to become pandemic.” They did recommend the bed isolation of patients and the disinfection of mess gear, handkerchiefs, and similar precautions for infectious diseases spread primarily by respiratory droplets. Where sick bays or isolation wards were not available, the use of sheet screens between patients was advised. On September 20, Bureau officials issued another circular memorandum, informing medical aides that influenza was now included on the list of reportable diseases. Medical personnel were instructed not only to report influenza cases in their weekly telegrams to the Bureau, but also to assist aides of other districts by informing them and the Bureau of the appearance of any communicable disease in epidemic form. Four days later, it had become clear to all that an influenza epidemic was well under way in military installations and urban areas. In response, BuMed officials called on naval officers to avoid the exposure and fatigue of their men, to relieve overcrowding, to avoid the quartering of large groups of men in any single compartment, to isolate all cases immediately, to prevent public assembly, and to use screens in barracks and sick quarters. Patients were also to be masked.

Yerba Buena Island

On September 23, one day before it was reported that influenza had hit San Francisco, Commandant Percival Rossiter of the San Francisco Naval Training Station (Yerba Buena Island) ordered an immediate and strict protective sequestration of the island. All personnel were required to remain at the station, and no visitors were allowed entry. Approximately 6,000 people were on the island, including officers and their families, a few hundred civilians, approximately 5,000 sailors, and about 30 yeomanettes. All interactions with others living in the Bay Area were halted except to receive supplies, and in those cases the crews of tugs were prevented from coming any closer than 20 feet from sailors on the dock. Given the wartime circumstances, some recruits were sent from the mainland to Yerba Buena Island. The nasopharynxes of the men were sprayed with a 10 percent argyrol solution (a topical anti-infective solution prepared by the reaction of silver oxide with gelatin or albumin) and they were required to wear gauze masks before they were allowed to board the ferry bound for Yerba Buena Island. Upon arrival at the island they were placed in a quarantine camp for several days. During this period they were required to wear masks, to have their throats sprayed with argyrol solution three times a day, and to maintain a distance of 20 feet from one another. The protective sequestration policy was to remain in force until all danger of the epidemic had passed.

Although the NPI implemented at Yerba Buena Island may have been effective in preventing an influenza epidemic on the island, they also prevented men from interacting with the wider Bay Area and from seeking entertainment there. Closed off from regular interaction with the outside world, sailors, officers, and civilians on Yerba Buena Island organized their own entertainment, such as circuses and festivals, to keep up morale. In early October, for example, a carnival was held that turned the facility into “a miniature Coney Island.” What we could not document was the availability of mail or telecommunications to all those sequestered on Yerba Buena Island.

By early November it was being reported that the number of new influenza cases was decreasing among both civilian and military populations in the San Francisco area, and that recent cases were milder in form. At the end of November it seemed as if the pandemic had passed. On Thursday, November 21, the protective sequestration of Yerba Buena Island was lifted and the facility was re-opened to interact with the outside world. Nevertheless, influenza cases among naval personnel did not return to epidemic proportions after November 21, and those cases that did develop were mild. Yerba Buena Island experienced its first influenza case on December 6. Throughout the rest of December 1918 and into January 1919, Yerba Buena Island continued to experience influenza and pneumonia cases (a total of 28 of the former, and 21 of the latter), with at least 3 deaths from influenza and 2 from pneumonia.

Research Materials

Because of its proximity and normal interaction with the wider Bay Area, members of the Center for the History of Medicine’s Influenza Research Project consulted primary source materials on San Francisco as well as Yerba Buena and nearby Mare Island naval stations. Digitized sources include:
