The information
used in the above epidemiology presentation for the disease has been mostly
used from the study which is available at the AVERT website which is committed
to fighting this disease in the United States by influencing people through
statistics and other methods of data collection on the topic of HIV and AIDS. All the information available here is
referenced and carried from the CDC health reports for the mentioned year. These studies use the standards methods of
expressing morbidity and mortality. Morbidity refers to the appearance of new
cases of the disease in a certain population while mortality refers to the
number of deaths caused by the disease out of the total population (RICE, 2015) . It is very hard to
measure the correct mortality rate of AIDS patients. It is mostly due to the
nature of the disease as it is very hard to identify if the patient died of
AIDS related problems or complications or due to other reasons. The treatment
of AIDS is done by powerful drugs with strong side effects and it is therefore
not uncommon to see people struggling with medications for this disease (Biggs, 2012, pp.
8-32) .
It is also
important to take care of timelines whenever compare rates for different
population segments. The rates of 2008 for example cannot be compared with the
rates of 2010 of another social group. It is therefore imperative in any study
and also in this study of AIDS/HIV in the United States to especially compare
trends from the same time period. This is the reason why most information
viewed here in this assignment is for a few years back because established data
is available for these years for all social groups and it can be compared to
find both future trends as well as the endangered social groups against this
particular disease. The prevalence of HIV is usually found in United States
using two methods. The first method is of collecting data in different people
and regions and then combining them together to find the estimate of people at
risk. There are problems with this method as it is difficult to find out the
ethnicity of people as well to find out their true social status as mostly only
the place of survey is available for the record. Precision is not available
with method and it is difficult to predict the trends for future. The second
method uses mathematics and combines the available data with the data of the
previous years to find different medical trends and probabilities. This
mathematical method is much more useful as it provides relevant data and allows
medical researchers to predict the future of the disease by using different
available models and theories. The symptoms of HIV appear over a long time
frame and therefore comparative methods as well as backdating methods are quite
useful in finding the trends related to HIV (Osmond, 2003) .
