Transcript of AIDS

A sexually transmitted disease Stands for Acquired ImmunoDeficiency Syndrome AIDS is caused by HIV It is the last stage of a HIV infection. stands for HIV Human Immunodeficiency Virus HIV attacks the human immune system. It infects the white blood cells. Genetic information of the virus is implanted into the white blood cell's DNA. 1 2 The cell acts as a virus-producing plant. 3 Multiple copies of the virus are released into the bloodstream. 5 The cycle repeats. As white blood cells start to die off... 1 The number of white blood cells decrease. 2 The body's immune system becomes more vulnerable to infections and are less able to fight them off. 3 Eventually, so many white blood cells die off that the immune system is incapable of fighting off infections. After many years (8 to 11 on average), AIDS is diagnosed. 4 The exhausted cell eventually dies as it is unable to carry out metabolic processes. Contact with bodily fluids such as blood and semen of an infected person may cause infection. Common Misconceptions of AIDS General Prevention of AIDS Signs and Symptoms Pnuemonia F Enlarged Lymph Nodes High Fever Seizures a Lack of energy/fatigue Night sweats Myth 1 HIV can be transmitted through contact with HIV-infected people HIV is spread only through bodily fluids like blood and semen (though tears and saliva is an exception, since the concentration of the virus is far too small). Myth 3 HIV survives for only a short time outside the body HIV can survive outside the body for hours if dry and weeks if wet, at room temperature in high concentrations. However, concentrations in bodily fluids are smaller and will live for only a few minutes in dry conditions. Myth 5 There is no need to practice safe sex when both parties are HIV-infected If safe sex is not practiced, both parties may be exposed to different strains of HIV (which may be drug-resistant etc.) Myth 6 Contracting HIV means a death sentence Although HIV has no cure, there is treatment available. A HIV-infected individual can continue to live normally for many years. Coma Consistent condom usage Condom usage can reduce the risk of transmission by 80%, through the prevention of contact with bodily fluids. Don't visit illegal tattoo parlors Tattoo needles in illegal tattoo parlors may not be sterilized and may cause infection Monogamy
(Have 1 partner for life) Treatment & Cures Monogamy enables you to restrict transmissions of HIV from other partners who might have HIV to only a trusted party. There's currently no cure for AIDS. However, there are many types of treatments. HAART Aggressive treatment used to suppress HIV viral replication and the progression of HIV disease. Weight loss However, it cannot be transmitted through air or water. Thus, any external contact with an infected person is unlikely to cause HIV infection. Highly Active Antiretroviral Therapy
