is a perfect parallel to today's situation. mary mallon was an asymptomatic carrier of typhoid fever.

despite multiple forced isolations, and even a jail sentence, she defied all doctor and government official orders to quarantine. mallon was ultimately responsible for at least 3 confirmed deaths with at least 50 more suspected, while infecting hundreds.

she always denied the severity of the illness, refused to believe she was ill, and ignored doctors orders.

those who ignore history are doomed to repeat it.
