HIV/AIDS: An Overview 2 “The HIV/AIDS epidemic is an unprecedented crisis that requires an unprecedented response.” These are the words of former United Nation secretary Kofi Annan. These words are in no way an exaggeration, as the HIV/AIDS crisis is indeed a global phenomenon. Since the first reported case of HIV in the United States in the 1980s, many conflicting theories exist with regard to its origin. Even after 20 years, this disease still puzzles scientists and has been a subject of fierce debates and countless arguments; homosexual lifestyle as well as suspected vaccine programs are few of the theories blamed for its origin. The reality is, HIV/AIDS can affect anyone, regardless of race, age, sex, or sexual orientation. Therefore, the purpose of this overview is to explain the difference between HIV and AIDS as well as discuss the changes in the immune system as HIV patients become AIDS patients. Additionally, it will provide an analysis of the reason the body’s innate immunity fails in AIDS patients, and describe the available treatments for HIV/AIDS patients. Furthermore, it will discuss precautions use to prevent the spread of the disease as well as provide a description of at least one global awareness campaign in the fight against the spread of HIV. Differences between HIV and AIDS The acronym HIV stands for human immunodeficiency virus, which belongs to one of a group of viruses known as retroviruses. HIV occurs as virus enters the body and damages or kills the body’s immune system. The body in turn would try to compensate by producing new cells to contain the virus; overtime, the HIV wins and systematically destroys the body’s capability to fight certain infections and cancers.

HIV/AIDS: An Overview 3 On the other hand, the acronym AIDS means acquired immunodeficiency syndrome. This happens to be a chronic, life-threatening condition attributed to the human immunodeficiency virus (HIV). As immune-cells falls to critical levels, the virus damages the immune system, and the body loses its ability to fight bacteria, viruses, and other elements. This susceptibility makes it more difficult to resist infections that the body would normally resist. Conditions such as meningitis and pneumonia are extremely common in patients at the later stages of HIV as the virus becomes AIDS. HIV Transmission HIV transmission can occur in a number of ways; this may include through sexual intercourse, intravenous drug use, mother to baby, or blood transfusion. Sexual intercourse is the most common form of transmission, as infected individuals spread the disease to their sexual partners through the lining of the penis, vulva, vagina, mouth, or rectum during intercourse. In fact, Emedicine Health (n.d.) cites that, individuals already suffering from other sexually transmitted diseases such as genital herpes, gonorrhea, syphilis, Chlamydia, or bacterial
