What is doctor?
This city was the setting for the 1854 cholera outbreak.
What is London?
This object became the center of John Snow's investigation.
What is the Broad Street water pump?
This is the practice of using observations and data to investigate a scientific question.
What is the scientific method?
This is the term for the rapid loss of water and electrolytes from the body that makes cholera so deadly.
What is dehydration?
Snow became convinced that cholera was being transmitted primarily through this.
What is contaminated water?
London's rapidly growing population created serious problems with this basic public-health necessity.
What is sanitation disposal?
Snow's investigation showed that cholera cases were clustered around this.
What is the contaminated water supply/pump?
Snow's map helped him identify this kind of pattern in the cholera deaths.
What is a geographic/spatial pattern?
This theory claimed that diseases such as cholera were spread through contaminated air or foul smells.
What is miasma theory?
Snow famously investigated cases of cholera around this London street.
What is Broad Street?
Many London residents obtained their drinking water from these public sources.
What are water pumps?
What did Snow persuade officials to do to the Broad Street pump?
What is remove the pump handle?
This type of evidence compares disease cases with a possible source of exposure.
What is epidemiological evidence?
This microorganism, later identified as the cause of cholera, is associated with contaminated water and food.
What is Vibrio cholerae?
What made Snow's approach revolutionary compared with the prevailing explanations for cholera?
What is his use of data, mapping, and geographic patterns to test a hypothesis about disease transmission?
This rapidly growing population in what places made disease transmissions more likely.
What is urban cities?
Why was removing the pump handle important even though it did not immediately prove exactly how cholera was transmitted?
What is it prevented people from using a suspected source of contaminated water and helped stop the outbreak, providing practical evidence supporting Snow's hypothesis?
Why was Snow's argument initially controversial?
What is because many scientists and physicians still believed in miasma theory and did not accept his waterborne explanation?
