Background

Scope and content:

This collection contains 617 photographs in 8 albums documenting Los Angeles plague outbreaks in 1924-1925. The first album contains an index, which covers all 8 albums. The index headings have been used in the container listing to group the photographs. Some headings have been supplied for the container list. Included in all 8 albums are views of buildings, alleys, restaurants, and city dumps where infected rats were found or where human cases were reported. Some images show preventative measures taken by the State Department of Public Health to stop the spread of disease, including the destruction of buildings. Many of the structures pictured are shacks and other low income residences. Captions identify a "Mexican Village," "Chinatown," and "negro dwellings" in various locations. Some photographs in the first album show trapped rats and squirrels. The photographer or photographers are unknown, but the collection was possibly photographed by the California Department of Public Health. Typewritten captions are found below the photographs, and are reprinted in the container listing.

Other descriptive data:

On October 19, 1924, Lucena Samarano, a Mexican woman living on Clara Street in Los Angeles, died from what was later determined to be a case of pneumonic plague. Plague was suspected after the woman's husband and nurse died a few days later. Others in the neighborhood began to show signs of infection, and by October 28, eighteen patients (all friends and relatives of Lucena Samarano) were hospitalized with signs of severe pneumonia and all died in an average of four days. The diagnosis of pneumonic plague came on October 31.

Plague was officially declared on November 1st. The Los Angeles City Health Department immediately quarantined the areas in which the current cases of plague had originated. Borders of the quarantined areas were patrolled and the Health Department provided guards for the homes where known cases of plague had occurred. Food had to be brought in with limited contact with the residents. The Baptist Mission Church in what was called the Macy Street District (the place where the plague originated) became a bacteriological laboratory for the examination of rats. Houses were inspected daily. Any cases of illness were sent to the Los Angeles General Hospital. Measures for the eradication of rodents and fleas began throughout the quarantined districts. Traps were set for rats, and each rodent caught was tagged and dated, and the location of its capture was recorded. Each rat was then taken to the laboratory for examination.

A plan of operation for dealing with the plague was also put into effect. Its measures included quarantine, prevention of the gathering of large groups of people in quarantined areas, a daily house-to-house inspection within the quarantined area, hospitalization of all cases of illness found within the quarantined area, the examination of all corpses by physicians, the establishment of a laboratory exclusively for the examination of rodents and human plague, widespread trapping and rat-proofing of buildings, tagging of all rodents collected, and proper disposa l of garbage.

The Macy Street District was an area in which the residences were originally well built, but had become dilapidated, with shacks built in the rear. This area was entirely surrounded by industry, and the inhabitants were composed largely of Mexican families who worked nearby. The route by which the plague reached Los Angeles was not determined. It was definitely established that this epidemic was of rat origin.

Previous major outbreaks of plague in California include two groups of bubonic plague outbreak in San Francisco in 1900-1904 and again in 1905-1909. The first outbreak saw 121 cases and 113 deaths, and the second 160 cases and 78 deaths. By the end of this 1924-1925 plague outbreak in Los Angeles, 32 cases of plague were diagnosed with 30 deaths.
