AIDS (acquired immune deficiency syndrome) is caused by the human immunodeficiency virus (HIV). HIV destroys the immune system, so that it is impossible for the body to fight off disease or even minor illnesses, and it is so deadly that in days it take the life, so far after cancer HIV is declared the deadliest disease in whole world, Specially in African countries and India its ratio is rising greatly, Cultural believes and religious creeds also help to avoid HIV, for example in Muslims this disease is obsolete, Because it’s a great sin to do sex without marriage, I don’t say no one in Muslims have HIV, It can be but in those who don’t practice or care about their religion which strictly prohibits to do sex without marriage.
AIDS is the last phase in HIV disease, when the body is unable to fight a disease or infection.
A person is said to be HIV-positive if antibodies to the virus are detected in his or her blood. It may take up to six months after infection for the antibodies to appear. Someone who is HIV-positive may appear to be healthy for 10 years or longer before the symptoms of AIDS develop.
HIV is not spread by mosquitoes, toilet seats, being coughed on by an infected person, casual contact with someone who is HIV-positive or who has AIDS, or by donating blood.
Because all blood has been tested for HIV since 1985, the risk of getting the virus from blood or blood products is extremely low.
HIV is spread only when blood, semen, or vaginal fluids from an infected person enter someone else's body. The specific behaviors that spread HIV include:
1. Sharing injection needles, syringes, or drug-use equipment with someone who is HIV-positive.
2. Unprotected (without a condom) rectal entry intercourse (anal sex) with someone who is HIV-positive. Anal sex often tears the rectal blood vessels, allowing the virus to enter the body.
3. Unprotected vaginal intercourse or oral sexual activity with someone who is HIV-positive.
Babies born to or breast-fed by women who are HIV-positive are also al high risk of contracting the virus.
Being touched, hugged, or lightly kissed by someone who is HIV-positive will not transfer the virus to you. As long as you practice the prevention behaviors you have virtually no risk of contracting the virus.
If your behavior puts you at risk for HIV infection, have a blood test six months after the risky behavior. Early diagnosis and treatment of HIV is important even before symptoms develop.
