- Please discuss the disease cholera in the country Haiti? Please mention both the global burden of the disease as well as the burden in Haiti. Provide data on mortality and morbidity, and distribution of disease burden by age, gender, or region. (chart and please refrence it) Who is most at risk in Haiti? Does Haiti have access to known treatments? why Haiti might have this disease profile. how you we explain this disease using a social ecological framework. please provide references?discuss methods used to control vector-borne diseases, specifically mosquitos. 1) Is there one method you think is more beneficial than others when it comes to the controlling and prevention of mosquito-borne diseases? Why/why not? 2) Also, how large do you think is the impact of human environmental change (man's activities) on emerging infectious diseases in animals and man?Make a Critique report about "INTERDISCIPLINARY RESEARCH APPROACHES TO EMERGING PATHOGENS OF DISEASES OF THE GLOBAL HEALTH CONCERN." Can use this as basis: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586606/
- (c) Consider spread of an epidemic of some infectious disease in some spatially distributed population of individuals, e.g. spread of Covid-19, or flu. List characteristics of such epidemic which a bottom up approach to mathematical modeling allows incorporating more realistically, or more easily, than a top down approach.The multifactorial causes of diseases often create philosophical problems in epidemiology. How does themultifactorial nature of disease impact:Disease classification, causal inference, and prediction?Select all the statements that are true regarding the drug treatments available for infectious diseases.□ Antiviral drugs are harder to develop than antibiotics because viruses must use our cellular machinery replicate. □ Very few anti-parasitic drugs exist because diseases caused by Eukaryotes are extremely rare all over the world.□ Fewer drugs are available to treat Eukaryotic pathogens because their physiology and functions are very similar to our own.□ Development of antiparasitic drugs are a low priority because the diseases they treat tend to occur in poor countries, and drug companies can't make money.□ Antivirals may quit working because rates of viral mutation are very high.□ There are more antiviral drugs than atibiotics because antiviral drugs are very easy and cheap to make.
- 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.File Edit Go lools Help Section 6: Graded Questions 1/1 NOTES E QUEST How Diseases Spread Apps O The frequency of contact between susceptible and infected individuals and the probability of infection per contact eve O The length of the infectious period and the probability of infection per contact event O The number of recovered individuals and the probability of infection per contact event Submit Q6.9. Why is it important to "flatten the curve" by reducing the peak number of infections during an epidemic? O Flattening the curve hastens the arrival of herd immunity for the population. O 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. O Flattening the curve reduces the number of people who need to be vaccinated. Submit Ye Q6.10.

- Which of the following does not refer(s) to distribution of a disease by time? a. Point epidemics b. Rural-urban differences c. Seasonal trends of a diseases d. Secular trend of the disease QUESTION 2 Which of the following statements is correct? a. A nuclear accident would probably result in cyclic patterns of health consequences b. The COVID-19 infection is an example of a point source epidemic c. If symptoms of depression experienced in a particular locality increase during certain months of every year, compared with other months in the same year, this is an example of secular trend in depressive symptoms d. Contamination of the drinking water source of a community by infectious agent(s) will likely result in a continuous common source epidemicAs an outbreak of disease spreads in a relatively isolated community, some contract tracing occurs, and likely transmission events identified. Contract tracing determines that a sample of 10 infected individuals caused the following number of secondary cases: (look at the attached image) -Calculate the average number of secondary cases and create a ‘who acquires infection from whom’ matrix of R0 numbers. Use this matrix to calculate the overall R0 number for the population.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
