Epidemiology
Working in a remote village, where there is a high prevalence in the number of patients with HIV there are a number of researches that can be conducted to reduce the infection rates to the minimum (Song & Chung, 2010). Depending on the research question, the research can take the observational form or the experimental form.
Observational and Experimental Designs
With reference to observational studies that can be carried out in the village on HIV, patients experience side effects with respect to using a certain drug. Most of the drugs tend to have some form of side effects that may come within a short while or may take quite some time. In this study, 300 participants will be selected from different age groups, ranging from 20 to 50 years. There will be three subsets, where the age groups will be distributed within 10 years of each other. This distribution will ensure that the patients are observed across the age divide to establish if there is a chance that there may be differences in side effects with respect to age. Observed over a period of two years, the patients will be monitored for any changes in the health alongside the drug that they are taking for HIV (Ciphi.ca, 2014).
In the same village, it is also possible to conduct an experimental study with reference to the HIV patients and the respective treatment that they receive. As such, using the same age groups, different sets of drugs can be introduced in the population. The control groups that would be composed in the same way as the experimental one would be given the conventional drugs of treating HIV. The test group on the other hand would be given the experimental drugs. The results would then be compared after a period of two years, to establish the differences notable. This would help in the development of new drugs in coping with the HIV scourge.
