Chapter 36.7, Problem 1CC
Summary Introduction
The epidemic is a sudden spread of disease in a population with a wide spread of infection rate that affects most of the population within a short period of time. For example, Cholera. The epidemic can be a common source epidemic or propagated epidemic.

Discuss how the SARS-CoV-2 virus causes Covid-19 disease became a "new" zoonotic disease and has resulted in a "fast" spreading World-Wide Pandemic. how has it evolute as a zoonotic disease, the mechanism of infection in humans, symptoms of disease, treatment and prevention. Describe how to "flatten" the curve and make the epidemic a "slow" epidemic by acting as a "social" vaccine.
5) Consider the following simulation result:

c) When does the epidemic peak?
40
50
Time
60
b) What proportion of the population gets infected?
70
a) What model do you think this simulation result is from?
80
90
d) Suppose 3 = 0.005 and y = 0.1. Calculate Ro for this model.
100
e) Can you stop the epidemic by adding more people to the population? If so, how many people
would you need to add?
The Zoomland epidemic does not mimic a real epidemic in every respect. What is ONE way the Zoomland epidemic is not an entirely realistic simulation?
A.
In the Zoomland epidemic we could tell who had interacted with whom (contact tracing). In real life there is no way to do any contact tracing.
B.
In the Zoomland epidemic people interacted randomly with others. In real life people interact much more with some members of the population than others.
C.
In the Zoomland epidemic, transmission only occurred when a person came into contact with an infected person AND a suitable vector. In real life some diseases do not require a vector for successful transmission.

- Explain the relationship between the three levels of prevention and the prevalence and/or incidence of a specific disease of your choice in a specific population. What are the health disparities for this disease and population you chose? Which of the three levels of prevention do you think receives the most public attention and resource allocation to address this disease? What do you think the rationale is and why?arrow_forwardThis article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic. Dr. Zikry is quoted as saying: “It’s become very clear to me what a socioeconomic disease this is...”. In addition, the textbook discusses the personal variables and socioeconomic status (SES) that are used to find patterns in disease (pp.112-118). What do you think Dr. Zikry meant by referring to the SES of his patients? Why was it important to find a pattern of personal variables and SES among the of victims of Covid-19 at the beginning of the pandemic?arrow_forwardUsing specific examples describe the syndromic surveillance systems. Briefly explain how the syndromic surveillance systems are different from traditional surveillance approaches to epidemic detection.arrow_forward
