Outbreak Investigation & Epidemiology
📋 What it is
Epidemiologists are "disease detectives" who track how illnesses spread through populations.
🗣️ Coach says
Epidemiology studies disease in whole populations. When an outbreak hits, "disease detectives" trace who got sick, where, and how it spread — mapping cases to find the source (a contaminated well, a food, a contact). This detective work stops outbreaks and shaped modern public health.
🧠 Memory hook
Epidemiology = disease detectives. Trace WHO/WHERE/HOW it spread → find the source → stop the outbreak.

😲 Whoa!
Modern epidemiology was born in 1854 when Dr John Snow traced a London cholera outbreak to a single contaminated water pump — and stopped it by removing the pump handle.

Say your answer out loud first — then reveal.
Traces how the illness is spreading (who, where, how) to find the source and stop it — disease detective work.
Epidemiology maps spread to control outbreaks.
