how can it spread?i know it but i want information in more detail AIDS (acquired immune deficiency syndrome) is a deficiency of the immune system due to infection with HIV (human immunodeficiency virus). As yet, there is no curative treatment and no vaccine for AIDS, but the symptoms and complications variably respond to antibiotic drugs, antiviral drugs,anticancer drugs, and radiotherapy.
AIDS is not present in all individuals who are infected with HIV. The proportion of those infected whose condition progresses to AIDS has varied widely in different countries and in different risk groups. Every year, AIDS will develope in between 1-5 per cent of people infected with HIV, but there is some evidence that in a few infected people (less than 1%) both the virus and the antibodies eventually disappear from the blood, suggesting that the body has fought off the infection.
Once AIDS has been diagnosed, the condition is considered fatal. By the end of the 1980s, nearly 100,000 men, women, and children in the US had been diagnosed as having AIDS and about 3/4 of them have died. In the UK (by the same date), approimately 2,000 people had been diagnosed as having AIDS of whom most have died.
The main risk groups are homosexual or bisexual men and people who inject themselves with drugs using unsterile needles and syringes. Many people with haemophilia also became infected in the early 1980s as a result of receiving infected blood products, but this route of infection has now been closed by better screening of blood. Other risk groups include heterosexual contacts of infected individuals, children born to infected women, and people who have received infected blood transfusions.
The virus infects a type of white blood cell known as the T4, CD4, or T-helper lymphocyte, which is crucial for the regulation of the immune mechanisms. The infected cell may die or the virus may remain dormant in the cell, with the possibility of later reactivation. In its most severe form (i.e.AIDS), HIV infection interferes with the immune system to make the individual susceptible to a variety of infections and cancers.
HIV has been isolated from blood, semen, saliva, tears, nervous system tissue, breast milk, and female genital tract secretions. However, only semen and blood have been proven to transmit infection.
The main methods of transmission are sexual contact (penis to anus, vagina, or mouth), blood to blood ( through transfusions or needle sharing in drug users), and from woman to fetus. Other rare methods are through accidental needle injury, artificial insemination by donated semen, and kidney transplants.
"Casual" or household spread does not occur. The infection is not spread by touching or hugging, by breathing the same air, or by sharing cutlery or crockery.
Until a cure or vaccine is found, prevention is the most important measure against AIDS. Risks can be reduced by practising safe sex. IV drug users should not share needles.
There is no cure for AIDS. Supportive treatment is available only for its complications.
I hope this helps read a book AIDS (Acquired Immunodeficiency Syndrome or Acquired Immune Deficiency Syndrome, rarely written Aids) is a disease characterized by the destruction of the human immune system. It stands today as a global epidemic, that originated in sub-Saharan Africa during the twentieth century. Although there are treatments to hinder the progress of AIDS, there is yet no known cure or vaccine.
AIDS is a measure of how much damage HIV has done to a person's immune system. It is not a disease. AIDS can develop after someone gets HIV. After HIV has been inside someone's body for a long time it can weaken or destroy their immune system. The immune system can't fight germs any more. They get different diseases or illnesses, also called opportunistic infections. Sometimes a doctor can still find that a healthy person with HIV has AIDS. Search AIDS on your Browser..
