As disease devours the world, ordinary people are forced to become pioneers of epidemic tracking. In the book Patient Zero by Marilee Peters, it talks about how various diseases are created, transmitted, and controlled. Each chapter gives context to the “patient zero” of various diseases, their emergence, how they were assessed, and their devastating effects. The evolution of Cholera, Typhoid, and the Black Plague helps society understand how diseases arise and how to contain them.
Body Paragraph 1: From mapping cases of Cholera, it was found that contaminated water caused Cholera, encouraging future scientists to test water sanitation as a potential spread of disease. John Snow created a map of all the water sources in London to track the spread of Cholera. The black bars on the map represented cases of Cholera and the “Broad Street Pump [had the] thickest [bars] near the pump and got less frequent further away”(45). This shows that the people closer to the contaminated water pump would be more vulnerable to contracting Cholera, proving that Cholera spreads in contaminated water sources. Cholera prepared …show more content…
According to page 76, “Mary Mallon was somehow able to pass on the Typhoid infection to others without showing any symptoms of the disease herself.” This shows that Mary Mallon was a healthy carrier of typhoid, revealing to scientists just how dangerous asymptomatic carriers can be. This discovery is important, because it shows how some people may spread a disease without explicit symptoms, showing why everyone should always stay hygienic to avoid subconsciously spreading a disease. In Coronavirus, healthy carriers also spread disease without symptoms. But thanks to the discovery of asymptomatic carriers in typhoid, the general public was advised to take safety measures like wearing a mask and social distancing to avoid accidentally passing it
