AIDS


However .
             researchers have not perfected any of these methods yet.
             There are many symptoms and stages of AIDS. Within two or .
             three weeks after infection with HIV, most people experience nonspecific .
             flu like symptoms. These include fever, headache, skin rash, tender lymph .
             nodes, and vague feeling of discomfort. These symptoms usually only last .
             one to two weeks and are known as the acute retroviral syndrome phase .
             during which HIV reproduces to very high concentrations in the blood, .
             mutates often, circulates through the blood, and establishes infections .
             throughout the body. After this phase infected persons go through the .
             prolonged symptomatic phase, which contains no symptoms and can last up to .
             ten years. During this time infected individuals remain in good health .
             while the HIV continues to reproduce and break down the immune system. .
             Eventually a person goes through the early symptomatic phase which can last .
             from a few months to several years while the levels of CD4 T-cells rapidly .
             fall and non life threatening infections are very common. Following this .
             stage occurs the late symptomatic stage. This includes extensive immune .
             destruction and serious illness that can last from a few months to years. .
             The person may have very low T-cell levels with infections that identify .
             AIDS. Progressive weight loss and debilitating fatigue occur in many .
             people during this stage. Because the immune system is in such severe .
             failure the person eventually enters the advanced AIDS phase. Severe .
             life-threatening infections and cancers cause death within one to two .
             years.
             There are only a few ways that HIV can be transmitted. It is .
             most commonly spread through sexual contact. In the United States alone .
             more than 400,000 people have been infected through sexual contact (US .
             Department of Health and Human Services 1). It is also spread by the .
             sharing of needles or syringes that results in direct exposure to the blood .
