In Community X (population 20,000), an epidemiologist conducted a prevalence survey in January of 2012 and reported an HIV prevalence of 2.2%. Over the next 12 months, the department of health reported an additional 50 new HIV cases between February 2012 and January 2013. The total population stayed constant at 20,000. Part 1 How many people had HIV in January 2012? Present or describe the formula you used to arrive at your answer. Calculate the incidence rate assuming no HIV-related deaths over the 12-month period. Present or describe the formula you used to arrive at your answer. Be sure to clearly indicate the numerator and denominator used in your calculation and include an appropriate label for the rate. In a summary of 200-250 words, interpret the results and discuss the relationship between incidence and prevalence. Discuss whether or not the epidemiologist should be concerned about these new HIV infections, assuming a previous incidence rate of 0.5 per 1,000 person-years prior to this updated risk assessment.
Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
number of HIV cases = 440 personsnew incidence rate = 2.25 per 1000 personsWhat is prevalence and incidence rate?Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
Prevalence rate = number of cases/total population × 100%Incidence rate is the proportion of new cases of a condition observed within a given period of time.
Incidence rate = number of new cases/population at risk × 1000population at risk = total population - previous casesThe number of people who had HIV in January 2012 is calculated as follows:
number of HIV cases = prevalence rate × total populationnumber of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.

In a normal heart, an increase in edv would result in.
Answer:
In a normal heart, an increase in edv would result in.
This causes the ventricular contraction force to increase, allowing the heart to evacuate the extra blood that has been returned to it. As a result, an increase in EDV leads to a rise in SV. By this process, a decrease in venous return and EDV causes a drop in SV.
Explanation:
An increase in EDV raises the heart's preload and, through the Frank-Starling mechanism, the amount of blood evacuated during systole (stroke volume).
What is EDV?The term "end-diastolic volume" (EDV) refers to the amount of blood in the left ventricle at the conclusion of ventricular filling. In an adult human, this volume is around 120 mL.
The amount of blood expelled from the ventricle during systole increases with an increase in EDV, which also raises the preload on the heart through the heart's Frank-Starling mechanism (stroke volume).
This causes the ventricular contraction force to rise, allowing the heart to expel the extra blood that was returned to it. Consequently, an increase in EDV causes an increase in SV. By this process, on the other hand, a decrease in venous return and EDV causes a drop in SV.
