🦠 Typhoid Fever: A Historical Menace
Typhoid fever, caused by the bacterium Salmonella enterica serova Typhi, was historically a deadly disease spread through contaminated food and water. It was discovered in the early 1880s by German researchers that this bacterium was the cause, leading to improved prevention measures. The concept of 'healthy carriers' who showed no symptoms but could still spread the disease was also identified, with Mary Mallon, known as 'Typhoid Mary,' being a notorious example. She unknowingly spread the disease while working as a cook in New York, leading to numerous infections and deaths. Despite attempts to cure her and prevent further spread, including quarantine and legal battles, Mary continued to deny her role.

Transcripts
typhoid fever is caused by the bacterium
salmonella enterica sorova typhi
the bacterium spreads mostly in food and
water that's been contaminated by an
infected person
for centuries typhoid was an invisible
menace killing up to one in five of its
victims
salmonella typhi's role in causing
typhoid was discovered by german
researchers in the early 1880s
the knowledge that typhoid is caused by
bacteria improved disease prevention
measures
it also led to the discovery that long
after seemingly recovering from an
infection
some people can still spread typhoid
these healthy carriers display no
symptoms and continue to shed typhoid in
their feces
the most infamous healthy carrier was
the cook mary mallon who became known as
typhoid mary
mary had emigrated from ireland to
america in around 1884
and worked as a cook for wealthy
families in the new york area
at some point she must have contracted
and seemingly recovered from typhoid but
was still unknowingly shedding the
typhoid bacteria
where mary cooked people would soon
become ill from typhoid
from around 1900 onwards she infected up
to 50 people several of whom died
mary had no idea she was contaminating
food and spreading typhoid with poor
hygiene
she wasn't unwell and would later insist
she'd never had the disease
in 1906 one of mary's employers hired a
civil engineer to investigate an
outbreak at his house
after ruling out other causes the
engineer george soper
began to suspect that mary who'd quit
her post three weeks after the outbreak
was the cause even though mary's
employer insisted she'd been in good
health
mary was hard to find it was not until
soper heard of an outbreak at a
penthouse on park avenue that he
discovered mary was the cook there
sopa confronted mary and demanded urine
and stool samples to test for typhoid
mary was outraged and frightened and
kicked saper out
sopa returned with the health department
and police mary was forced to provide
samples which were found to contain
high amounts of salmonella typhy
bacteria mary didn't know about germ
theory and continued to deny she was
spreading typhoid
her refusal to cooperate made health
authorities decide to quarantine mary to
stop her from spreading the disease
they also tried to cure mary of typhoid
with various drugs and wanted to remove
her gallbladder mary refused and
unsuccessfully tried to regain her
freedom by suing city authorities
and paying a laboratory to test her
stool between 1907 and 1910 she was
imprisoned in a hospital located on
north brother island
in new york harbour just northeast of
manhattan
while imprisoned mary became a minor
celebrity
although there were many other typhoid
carriers american newspapers
sensationalized mary's case
and turned her into typhoid mary
reporters highlighted that mary was an
immigrant
ignorant of germ theory a single woman
and had opposed public authorities
for the authorities imprisoning mary
soon raised uncomfortable questions
about restricting an individual's
freedom
in the name of public health in 1910 a
new health commissioner thought mary had
been imprisoned long enough
she was released after promising not to
cook again mary was given a job as a
lawn dress
this was a step down from working as a
private cook and paid less
after several years she changed her name
to mary brown and returned to cooking
in 1915 mary caused a major typhoid
outbreak at the sloan hospital for women
in new york city
where 25 people were infected and two
died she fled but was arrested by police
this time quarantine was permanent mary
was imprisoned and spent the rest of her
life living on north brother island
she died in 1938 age 68.
to this day the term typhoid mary is
still used to describe
anyone who's a carrier or transmitter of
something undesirable
for us mary's history remains important
on the one hand it shows how poor
hygiene can spread dangerous diseases
like typhoid
and how scientists can use
epidemiological and laboratory
investigations
to identify the source of outbreaks
on the other hand mary's story is an
uncomfortable example of how disease is
often unhelpfully blamed on
and associated with particular groups
such as immigrants ethnic minorities or
women
in the u.s typhoid eventually
disappeared not by mass imprisoning
carriers like mary
but by providing access to sewers and
clean water developing effective
vaccines and improving general hygiene
other countries have not been so
fortunate lack of access to safe and
affordable water
food and healthcare means that typhoid
remains a major problem in poorer areas
of the world
