Question

explain how the epidemiologic transition is related to the demographic transition.

Consider John Snow's work and the fact that the cholera bacterium (or microorganisms and their relation to disease) was not yet discovered at the time he identified the source of the epidemic at the Broad St Pump. Why, based on your current understanding, was he considered to be the Father of Epidemiology and what does it say to you about the strengths of epidemiology as a discipline?

Answer 1

Epidemiologic transition is a death change and causes death due to the cause of infectious disease in the nations. the connection between epidemiologic transition and demographic transition is the increase in incidence and prevalence of chronic noncommunicable disease with disease burden among populations.
Doctor john snow could not able to find cholera until water contaminated by sewage. In 1800 people not having a modern toilet or running water, they use only wells and street pumps to get water for their daily use. John snow believed that sewage dump near to the river and well-contaminating water and spread the disease. He worked hard and found that outbreak of cholera when people drinks water from the broad street pump. People living near to that area get cholera due to contaminated water. He found street pump water has white flecks floating it that is the source of contamination. using geographic data he found dead from the outbreak investigating as a case determine the pump water as a source. He made positive proof of the source of the epidemic. John snow called the father of modern epidemiology because he found the major threat to health in the 1800s that cholera as an infectious disease. He described as epidemiology is a health-related discipline it needs a range of education, research, knowledge on science and economics. In the 1960s and early 1970s, health workers used the epidemiology method to eradicate disease occurrence. The strength of epidemiology as a discipline combines with sociology that influences public health policy, medical practice to avoid risk factors. Production of knowledge for the practical cause effort on reducing health risk factors.
