Document Summary
Investigates causes/risks of disease: identifies trends in disease occurrence, epi definitions, outbreak. Sudden increase in occurrence of disease: epidemic, occurrence/increase of disease that is higher than expected, can be infectious disease, can also be chronic disease, example: obesity, pandemic. John snow figured out cholera was being spread through the water supply: statistical methods, plotting the deaths on a map, the big break through, water, mapping, brewery workers weren"t getting sick. They drank beer instead of water => water was spreading the disease: we still use mapping today, we still ask the important questions, steps in investigating an outbreak. Verify the diagnosis: find out what they are sick with, symptoms, construct a working case definition, diagnostic testing, must be tested to be able to confirm a diagnosis, make sure you are dealing with the correct disease. Find cases systematically: find and map the cases of the specific disease, example: coronavirus map https://gisanddata. maps. arcgis. com/apps/opsdashb oard/index. html#/bda7594740fd40299423467b48e.
