1. What is HIV/AIDS? Acquired Immunodeficiency Syndrome (AIDS) is a disease caused by Human Immunodeficiency Virus (HIV). AIDS is a major concern in almost every country in the world. The World Health Organization (WHO) estimates that the cumulative number of AIDS cases in the world is up to 2.5 million persons. AIDS is the sixth leading cause of death among people aged 25 - 44 in the United States.
2. The infection of HIV/AIDS in many countries Globally, 85% of HIV transmission is through heterosexual intercourse. In the United States, approximately one-third of new diagnoses appear to be related to heterosexual transmission. Male-to-male sexual contact still accounts for more than half of new diagnoses in the U.S. Intravenous drug use contributes to the remaining cases. Because the diagnosis may occur years after infection, it is likely that a higher proportion of recent infections are due to heterosexual transmission. Infections in women are increasing. Worldwide, 42% of people with HIV are women. In the United States, approximately 25% of new diagnoses are in women, and the proportion is rising. At the end of 2010, an estimated 91,500 people in the United Kingdom were living with HIV and around 1 in 4 did not know they were infected. The World Health Organization (WHO) estimates that around 34 million people in the world are living with HIV. The virus is particularly widespread in sub-Saharan African countries, such as South Africa, Zimbabwe and Mozambique.
AIDS is a major failure of the body’s immune system. This decreases the body’s ability to withstand again infection and suppress multiplication of abnormal cells, such as cancer. It affects the immune system including special blood cells (lymphocytes) and cells of the organs (bone marrow, spleen, liver and lymph glands). AIDS is defined as the most severe form of a continuum of illnesses associated with HIV or Human Immunodeficiency Virus infection. HIV from an infected person can pass to a normal person through blood, generally during unprotected sex with infected person and sharing needles or syringes that contain blood from the person who get infected by HIV. It can also pass from infected mothers to their babies during pregnancy, delivery or breast feeding though it does not spread through tears, urine faces or saliva. Sharing towels, clothing or toilet seats also doesn’t make HIV to spreads. Most people believe that the origin of HIV derives from a chimpanzee carrying a similar virus though scientific consensus says that the origin of HIV and AIDS could never have happened this way. Scientists and academicians debated the possibility that HIV evolved from accidental vaccine contamination and subsequent transmissions mostly to African villagers. HIV/AIDS was first known in 1981, July. At that time, it’s found among gay men in New York and California. About the same time, emergency rooms in New York City have a lot of men presenting with fevers, flu-like symptoms. However, this is not the beginning of that disease. Actually in 1959, a man in Africa died of a mysterious illness and decades later after checking his blood samples, he was confirmed died due to HIV infection.
At this time, HIV, which could lead to AIDS were unknown and feared virus that was untreatable and fatal. However, as research, investment and commitment into understanding HIV and AIDS increased, the outcome of people living with HIV improved around the world. 6 years after 1981, precisely, 1987, a new treatment found that is hailed as the first step in HIV/AIDS. The drug Retrovir is FDA approved and begins to be used in a certain doses to treat people infected with HIV. Soon after that, Ronald Reagan, the 40th president of United States finally acknowledges the HIV/AIDS problem and for the first time uses the term “AIDS” in a public speech...
