Epidemiology can be said to be a key factor of science to public health. HIV is an epidemic and a concern to the public health since it emerged back in the early 1980s. Since it emerged, there has been numerous research and development about the HIV both in the developed and, underdeveloped countries. HIV may be caused by a virus and its effect may be felt throughout the world.
HIV is a serious public health issue. Globally it is a significant cause of mortality regardless of age, gender or race. Though, there have been a number of developments on HIV there is no known cure or vaccine. People whom may be infected with HIV may be said to have (AIDS) the Acquired Immune Deficiency Syndrome. HIV might be mainly transmitted through sexual contact. Based on data that might have been collected from animals, we see that the HIV establishes itself into the body after a given period of 72 hours. The risk of contracting the virus is higher on the male person who has not been circumcised. The risk also increases when there might be repeated exposure to the virus (Howard Libman, Harvey J. Makadon, 2003).
According to Paul E. Sax, Calvin J. Cohen, Daniel R. Kuritzkes (2010), they believe that, since the epidemic of the virus, there has been over 60 million infected people worldwide and a little over 2 million in the United States of America. The virus has resulted with over 20 million deaths worldwide and of the remaining over 40 million 95% of them may be living in the developing countries. According to statistics done we see that almost half of them maybe women and a little over 3 million might be children under the age of 15 years. Of the over 2 million living with the virus in the United States, at least half of them might have died due to complications brought by the virus.
It is important to note that, of all the people infected by the HIV, in the end they will develop AIDS depending on their defensive mechanism and general health. The origin of the disease is still a mystery with some theories put in place. The epidemic has been enormous and, the first case might have been reported back in 1986 in Madras, India. In India, there are three groups, which get tested, for the disease. These are pregnant women who go for check ups, drug users and those who go for checkups in the special clinics for sexually transmitted diseases (Savitri Ramaiah, 2008).
In the central Asian countries, the epidemic of HIV is still in its early stages. Though, there has been a numerous increase in the changes of those infected in the recent years. The virus infection among adults in the Central Asian countries may vary between 0.14 to 0.01%. There are NGOs in the area which are trying to educate and help people in both areas that may be highly affected and those that are not (Joana Godinho, 2004).
In conclusion, I believe that HIV is a major public health issue and that people should put more effort to finding ways of arresting it. We see that, in the recent years, it may have caused a lot of deaths leading to a high-mortality rate globally.
