Causes of HIV/AIDS
Symptoms of HIV/AIDS
Effects of HIV/AIDS on society
The human disease that I will be researching on is HIV/AIDS. HIV/AIDS is a sexually transmitted disease. It can infect the body if an individual has unprotected sex with an infected person, or use an infected needle. or from a mother to an unborn child.
HIV/AID is a deadly disease that can not be cured, it has taken the lives of millions of people around the worldwide; it attacks the young, the middle age and the old. This disease is well known to rake havoc in Africa.
But does HIV really exist? Does HIV really cause AIDS? HIV stands for Human Immunodeficiency Virus, while AIDS stands for Acquired Immune Deficiency Syndrome. AIDS is caused by the HIV virus. At least sixteen thousand (16,000) HIV viruses can fit on a pinhead. Below is a structure of the HIV virus.
If a person is infected with HIV/AID it most likely will attack the immune system. According to (Definitions-immune-system-The immune system n.d) the immune system is the body’s defense system. It uses white blood cells and special proteins to fight foreign organisms. It is also controlled by specialized white blood cells called CD4 cells. The proteins called antibodies are manufactured against specific organisms. HIV affect the immune system by specifically attacking the CD4 cells. The HIV antibodies produced by the immune system are unable to overcome the infection overtime, HIV progressively weakens the immune system. Then the person becomes “immunodeficient” and the weak immune system will no longer effectively defend the body.
When the immune system is weakened, the body becomes vulnerable to a variety of infections, cancers and opportunistic infections” take advantage of the weakened immune system. Eventually the immune system is so weak that the body is overwhelmed by infections and/or cancers, and the person dies.
In addition there are different types of the HIV virus such as HIV-1 & HIV-2, both are transmitted in the same ways. HIV-2 is less infectious; people with HIV-2 remain healthy for a longer time after infection. While HIV-2 is common in West Africa, while HIV-1 is the most common type worldwide
Additionally, AIDS is Acquired Immune Deficiency Syndrome. A “syndrome” is a group of symptoms & signs associated with the same underlying condition. Thus, the variety of opportunistic infections & cancers cause a variety of symptoms & signs. This group of illnesses with their symptoms & signs makes up the syndrome “AIDS”.
Overall, this deadly HIV virus. first known case was in 1959.Possibly said to have been transferred between species. HIV-1 was probably transferred to humans from chimpanzees in Central Africa. While HIV-2 was probably transferred to humans from the Sooty Mangabey monkey in West Africa
It s original discovery was 1981 in the USA when the AIDS syndrome was first recognized as a new disease. Thereafter, The HIV-1 virus was first identified in 1983 in the USA and the HIV-2 virus was first identified in 1983 in France.
