AIDS(Acquired Immune Deficiency Syndrome is various sick things caused by an immunity system stopping working by being infected with the virus -HIV(Human Immunodeficiency Virus)-.
Even if infected with HIV, there is no condition and it may move to others the first stage.
1．It is infected and several years pass from several months
2. The initial condition (a swelling of generation of heat, diarrhea, a rash, and lymph gland, headache, a cough, weight reduction) of AIDS begins to appear.
3. The symptoms of AIDS are shown.
4. The leukocyte in the blood which keeps the body decreases.
5. An opportunistic infection, an opportunism malignant tumor, a cranial nerve obstacle, etc. are started.
6. It results in death.
HIV destroys the immunity system introduced by (1). Now is impossible for curing, if it becomes impossible to make an antibody and is infected. (In detail structure of HIV immunity mechanism destruction)
In the present world, it is said that there are about 42 million AIDS patients and a HIV infection person. Especially many areas are south Africa of Sahara (29,400,000 people). Subsequently, they are south and southeast Asia (6 million people), and Latin America (1,500,000 people). And it is spreading rapidly also to Europe, a center and East Asia, Pacific coast countries, and Japan, and, now, has become a big threat on a scale of the earth in recent years．
The illness of AIDS moves through humors (blood, semen, vagina secretion liquid, mother's milk, etc.) fundamentally. That is, a possibility of being infected with "transfusion", a "sexual act", and "mother's milk" is high. Although saliva etc. is considered to be also the cause of infection, since about 3l. saliva is required at once to be infected with saliva, it seldom becomes a cause.
In this, especially a dangerous thing lets blood pass, and it is said that it is infected in 90% of probability (transfusion, a blood product, and common use of a hypodermic needle).
Although there is a sexual act only 0.1 to 1% as probability, 70 to 80% of the rate infected with AIDS is a sexual act. Moreover, when a mother is a HIV infection person, a possibility that will pass and placenta infection, birth canal infection, and mother's milk infection will take place is 30%, and is said for especially the rate in a developing country to be high.
Many infection people have come out in developing countries. A child is sometimes plentifully infected by the mother having been infected. (In Detail...Why Are there many AIDS infection persons in developing countries?)
And since there are people without the right recognition, there are prejudice to an AIDS patient and discrimination.
Since the cure is not established, it is important for AIDS to avoid infection first of all. It is important. Moreover, it is possible to take a prolongation-of-life measure, after being infected with a HIV virus before showing the symptoms of AIDS.

The measure against infection |
|
* HIV antibody inspection at the time of blood donation -- When donating blood, a blood test is conducted, and it investigates whether there are any abnormalities in the blood. However, since the antibody of HIV is not made unless it becomes after six - eight weeks, after being infected, the right result cannot be obtained.
* Use of a heated blood product -- A long time ago, there was many infection by the blood product used for a hemophiliac. It is because this was using the unheated blood product, and since HIV is weak to heat or an antiseptic, it is obliged to use a heated blood product in Japan now.
|
Prolongation-of-life measure |
|
* It is called an anti-AIDS agent which suppresses multiplication of HIV and lengthens the period to the onset of a disease, and a prolongation-of-life measure is planned.
|
Prejudice and the measure against discriminating |
|
* UNAIDS is interlocked with, and what called red ribbon movement is performed in various organizations all over the world.
