"Most harmless and yet the most dangerous woman in America” is how Irish woman Mary Mallon was once described after she was identified as the first known asymptomatic carrier of typhoid fever in the US. Found to be a super spreader of the disease and quarantined for 26 years, her story became a legendary cautionary tale in the history of public health (2021).
