Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome HIV/AIDS Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome
What Is HIV/AIDS? Acquired immunodeficiency syndrome (AIDS) is caused by the human immunodeficiency virus (HIV). HIV attacks and destroys white blood cells, causing a defect in the body’s immune system. The immune system of an HIV-infected person becomes so weakened that it cannot protect itself from serious infections. When this happens, the person clinically has AIDS. AIDS may manifest as early as 2 years or as late as 10 years after infection with HIV.
Clinical Spectrum of AIDS Group 1: Acute infection 0-3 weeks Window period: Seroconversion 3-12 weeks Group 2: Asymptomatic infection 0-10 years Group 3: Persistent generalized LAP Group 4: Other HIV-related diseases Constitutional diseases Neurological disorders Opportunistic infections Secondary neoplasms Other conditions

Signs and Symptoms of AIDS Fever of unknown origin Enlarged lymph glands Skin rashes and cough Persistent diarrhea Severe weight loss Skin lesions Loss of appetite and fatigue

Diagnosis of HIV Mainly serological Through antibody testing with ELISA; if positive, confirmation by Western Blot Culture of blood and tissues RT-PCR:mainly for follow up
HIV test and counseling
Treatment of HIV Infected Patients At present, no drug or therapy can cure AIDS Availability of anti-AIDS vaccines appears unlikely in the near future A combination of three antiretrovirals (ARVs) is the gold standard for treatment ARVs are not universally available, are very expensive and must be administered correctly
