Chapter 29.4, Problem 1CR
Summary Introduction
The endemic infectious disease is constantly found over long the periods of time, but it is usually occurs at only a low incidence in the population. The epidemics may be originate from a common source or host to host origin. In epidemiology, the basic reproduction is the typical number of secondary cases of an infectious disease arising from a characteristic case in a totally susceptible population and it is denoted by R0.

Calculate Vaccination Coverage needed to attain herd immunity for Density-dependent and Frequency-dependent modes of transmission given parameters values shown.
β = 0.002 S = 500 y = 0.2. R0 =5, and threshold density of susceptible individuals is 50.
Q6.9. Why is it important to "flatten the curve" by reducing the peak number of infections during
an epidemic?
Flattening the curve hastens the arrival of herd immunity for the population.
Flattening the curve reduces the likelihood of exceeding the health care system's capacity.
O Flattening the curve eliminates the need for community mitigation strategies like social distancing.
Flattening the curve reduces the number of people who need to be vaccinated.

The fact is that CDC works for big pharma/special interests not public safety as the CDC whistle blower documents prove. The fact is that this is about money not public safety. The fact is that some of these vaccines have little benefit/effectiveness and serious risks. The fact is real natural immunity and vaccine derived immunity are not the same thing at all and our babies would be protected from many/most infectious diseases if their mothers were allowed to have natural immunity and pass it to their babies in breast milk, and we had true herd immunity through adults who had lifelong natural immunity. The fact is vaccine induced immunity typically does not hold for long and often misses the target, and the neurotoxins and foreign ingredients/DNA, etc. are causing a generation of allergic/arthritic/immune system…arrow_forward
