Mary Mallon was born in Ireland in 1869 and then immigrated to the United States in 1884, where she built a career as a cook for hospitals and wealthy families. However, Mallon was an asymptomatic carrier of typhoid fever, an illness that showed symptoms as vomiting, extreme tiredness, and fever, and due to her asymptomatic condition, ended up spreading the disease to dozens of people through her cooking. She was the first asymptomatic carrier of the illness at the time in the US.
The photo to the left appeared in a 1909 article that named her "Typhoid Mary."
Soper, of course told the New York City health department of his findings, and they arrested Mallon for being a public health threat and took her to a local hospital where she would be forced to give urine and stool samples.
Upon giving samples, it was discovered that massive amounts of the bacteria lived in her intestines and gall bladder. Upon hearing the news, Mallon admitted that she almost never washed her hands after using the bathroom before returning to the kitchen to work.
Upon receiving the results, Mallon would be sentenced to quarantine on North Brother Island where she would be ordered to give samples multiple times a week.
The photo to the right was recovered from Science History Images and was taken of Mallon sometime in 1907 while in her first quarantine on North Brother Island.
Speaking of superspreader events, the White House held an in person event on October 20th, a few days prior, where a handful of people attending an event in close quarters were asymptomatic carriers of the virus. Most were horrified that such an event take place, and that masks were not worn on any of the party-goers. Of course, since it was politicians who were mostly involved, the media reamed them for a few days before focusing on another story. However, if you google "super spreader event" the photo below is the first to pop up, just as Mary Mallon is one of the first hits when you search for typhoid. In both cases, the media had the power to give a literal face to those involved in a health crisis. Image from US News and World Report.
