What are the key assumptions in simple SIR modeling of infection dynamics? (check all that arecorrect):No vaccines are in use.more than one type of host can be incorporated (vector, animal, etc.)V All hosts can fit into one of the three compartmentsONo hosts are susceptible.Recovered subjects cannot be reinfected.O Hosts die and are removedrom the model.O The population is static (not increasing or decreasing).

Susceptible-infected-removed (SIR) model gives a theoretical framework to predict, investigate and…

Which of the following is NOT true about the current coronavirus global pandemic (COVID-19)? O Laboratory diagnosis of infection is based on detecting serum antibodies against the causative microbe O Person-to-person transmission can occur through respiratory secretions (droplets and/or aerosols) O The causative microbe can infect many tissue types by binding to a cell's Angiotensin Converting Enzyme (ACE2) receptor O Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Three of the vaccines currently authorized in the US are nucleic acid vaccines O

Mouse Infection A model for the spread of an infectious dis- ease among mice is NP = rN - ar(a + b + v) dt b + y, where N is the size of the population of mice, a is the mortal- ity rate due to infection, b is the mortality rate due to natural causes for infected mice, B is a transmission coefficient for the rate that infected mice infect susceptible mice, v is the rate the mice recover from infection, and y is the rate that mice lose immunity. Show that the solution to this equation, with the initial condition N(0) =(a + b + v)/B, can be written as (a + b + v), 2{(R – a)e" + a], BR N(t) = where R = a - (1+, b + y
During the 2015 Ebola outbreak in West Africa, Ebola aid workers like Abdul Lebbie engaged in a practice called contact tracing. These contact tracers locate and isolate (through quarantine) individuals who may have come into contact with an infected individual. Contact tracing is an attempt to reduce the RO of a disease by: reducing the infectious period reducing the transmission rate reducing the virulence increasing the infectious period O increasing the transmission rate
The epidemiologic triangle is a graphic demonstration of relationship among the following, EXCEPT: O Immune status O Environment O Agent O Time
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.

Scenario: As a nurse supervisor working in a COVID 19 ward facility you must know the infection prevention and control measures to prevent cross contamination from one person to another. Applying the Theory of Patricia Benner, how will you consider that you are an expert? Expound your answer Applying the nursing theory of Katie Eriksson, how will you promote caritative caring in a covid19 positive patient?
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.
Which of the following is mismatched? O Indirect contact transmission - person-to-person transmission of a microbe by physical contact between the persons None of the other four answers is mismatched (All are correctly matched) Systemic (generalized) infection - microbes or their products (e.g., toxins) spread throughout the body Endemic - disease is constantly present at some level in the population O Reservoir nonliving of infection - continual source of an infectious microbe, either living or
