Pump Handles and Public Health
Body
Health care is often thought of as something that happens one patient at a time in a clinic or hospital. Public health takes a broader view and is focused on improving the health of entire populations. In 1854, a London physician helped stop a deadly cholera outbreak by removing a simple pump handle. That moment would become one of the earliest and most powerful examples of public health in action. Back then no one understood how cholera spread. Many believed it was caused by “bad air” or mysterious environmental forces. They did not know that it was actually caused by a bacterium that was spread through contaminated water sources.
