Mary Mallon (Typhoid Fever)

Keynote about Mary Mallon:

  • known as Typhoid Mary
  • contaminated 51 people during her job as a  cook
  • Mallon worked as a cook in NY city area from 1900 to 1907


Mary Mallon (September 23, 1869– Nov 11, 1938), better known as Typhoid Mary, was the initial person in the United States determined an asymptomatic provider of the microorganism associated with typhoid fever. She was presumed to have contaminated 51 people, 3 of whom passed away, during her job as a cook. She was two times forcibly separated by public health authorities as well as died after an overall of nearly 3 decades in isolation.

From 1900 to 1907, Mallon worked as a cook in the New york city City area for seven families. [4] In 1900, she worked in Mamaroneck, New York, where, within two weeks of her employment, residents developed typhoid fever. In 1901, she moved to Manhattan, where members of the family for whom she worked developed fevers and diarrhoea, and the laundress died. Mallon then went to work for an attorney; she left after seven of the eight people during that family ended up being ill.

In 1906, she took a position in Oyster Bay, Long Island, and within two weeks 10 of the 11 members of the family were hospitalised with typhoid. She transformed works once more, as well as similar events occurred in three more households. She worked as a cook for the family of a wealthy New York banker, Charles Henry Warren. When the Warrens rented a house in Oyster Bay for the summer of 1906, Mallon went along too. From August 27 to September 3, 6 of the 11 people in the household fell victim to typhoid fever. The disease at that time was “unusual” in Oyster Bay, according to 3 medical doctors who practised there. Mallon was consequently hired by other families, and outbreaks followed her.

Among the infections Mallon caused, at the very least three fatalities were credited to her. However, due to her use of aliases and refusal to cooperate, the exact number is unknown. Some have actually estimated that she may have triggered 50 fatalities.

Mallon was the very first asymptomatic typhoid carrier to be determined by clinical scientific research, as well as there was no policy providing guidelines for handling the situation. Some difficulties surrounding her situation stemmed from Mallon’s vehement denial of her possible role, as she chose not to acknowledge any sort of connection in between her working as a chef as well as the typhoid situations. Mallon preserved that she was completely healthy and balanced, had actually never ever had typhoid high temperature, as well as could not be the resource. Public-health authorities figured out that permanent quarantine was the only method to stop Mallon from triggering significant future typhoid outbreaks.
