What is AIDS?
The acquired immune deficiency syndrome (AIDS) was first described by Centers for Disease Control and Prevention(CDC) IN 1981. HIV is a disease which attacks body’s immune system which decreases your ability to fight against infection. When your immune system gets low and body cannot fight infections then AIDS occurs.
How it is transmitted?
HIV can be transmitted via blood, semen, pre semenal fluid, vaginal fluid, breast milk, and other body fluid that contain blood. Saliva, tear, urine does not contain enough HIV for transmission. The most common way HIV is transmitted is via blood and semen during unprotected anal, vaginal sex with an HIV infected person. Risk of transmission via oral sex is low but not risk free. It can also be transmitted by sharing contaminated needles, injections.
Stages of HIV Infection:
After exposure and transmission of HIV, it spreads throughout the body and blood CD4+ count falls dramatically. Untreated HIV replicates billions of virion particles a day. The disease has four steps:
- Acute HIV infection: fever, rash, oral ulcers, loss of appetite, weight loss
- Asymptomatic HIV: decrease in lean body mass without apparent total body change
- Symptomatic HIV: fever, sweat, skin problem, fatigue
- AIDS: Advanced stage of HIV
