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 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
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 × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number 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.

When speaking about the mind-body connection we must realize that in fact the mind is the same as the body. This 'connection' was rather artificially created. Usually we can describe it like this; when you're feeling sad or depressed (if you understand this as a mental state/state of mind) your body is also affected - you sleep more as you're more tired, you feel without energy, etc.
Another common way is to mention pain - when you cut your finger for example (a part of your body) you can experience intense pain (a mental state).
However, it is important to understand that every mental state corrresponds to some changes that have happened in the brain which make us perceive in the world in such a way (pain and depression are both understood as consequences of different neutrotransmitter levels and functioning for example).
The correct answer is 30: this is the age when most women have already gained an education and started their careers, but when they can still biologically have children: at the age of 42 some women would have problems having children, but around the age of 30 many women feel secure enough but also under the pressure of time.
