- If the incidence rate of a very serious disease is 25/100,000 person-years and the prevalence of this disease in the population is 75/100,000, what is the average survival time of individuals who contract this disease? [Assume the population is in steady state] * Hint* Formula (D=P/IR)Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the incidence rate from October 1, 2004, to September 30, 2005, using the midpoint population (population alive on April 1, 2005) as the denominator. Express the rate per 100 population.The ratio of male-to female age-adjusted mortality rates in the United States for pneumonia and influenza is 1.7. This means that compared to the age-adjusted mortality rate for females, the rate for males is O 17% lower O 17% higher O 70% lower O 70% higher
- Which of the following changes in parameters reflect the effect of poor nutrition on the spread of a disease in a community relative to an identical community that has access to quality nutrition? Use the standard notation where 3 (beta) denotes the constant rat of infectivity, and y (gamma) the removal rate. O The rate of infectivity decreases. The rate of infectivity increases.Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons.

- A population of 30 rabbits has been introduced into a new region. It is estimated that the maximum population the region can sustain is 400 rabbits. After 1 year, the population is estimated to be 90 rabbits. How many rabbits will there be after 3 years? In a city whose population is 100 000 an outbreak of flu occurs. When the city health department begins, its record keeping, there are 625 infected people. The number of infected people N is increasing at a rate proportional to the square root number of infected people at time t in weeks. One week later, there are 1600 infected people. Find the number of infected people two weeks after the record keeping begins.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?A. Provide a brief description of a hypothetical food-borne outbreak case. Click or tap here to enter text. B. Provide hypothetical data sets corresponding to the following tables (simply fill out the tables, do not remove rows nor columns but you may add more rows for your cases/incubation periods/food items if you wish to): Table 1: Case status and demographic factors Case (Y/N) Record Number 1 Sex (M/F) Age (in years) 3 4 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Table 2: Incubation periods and case counts Incubation period (days after exposure) 1 Number of cases 2 3 4 5 6 7 Figure 1: Epidemic curve
