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.

Paralysis
Explanation:
Paralysis: Loss of muscle function and loss of ability to move some or all body parts.
Types: Monoplegia, hemiplegia, paraplegia, or quadriplegia; spastic or flaccid
Causes: TIA, palsy, head or spinal cord injury, muscle weakness due to any medical illness
Research 1: Tetraplegic French man, paralysis due to accident. Improving movement with brain-controlled exoskeleton
Research 2: A patient from Lyon, paralytic due to spinal cord injury from falling from the house balcony; initially considered permanent damage; now on brain-controlled exoskeleton
Research 3: Functional electrical stimulation improved functionality
Research 4: A patient from hit and run accident, chest down injury and paralysis, improved with electrical stimulation
Research 5: A paralytic with spinal cord injury with permanent loss, recovered completely with rewiring nerves technology
The above research and treatments shows that technology can produce remarkable changes in the life of paralytics.
