AIDS (Acquired Immuno Deficiency Syndrome) The bacterium is called HIV (Human Immuno Deficiency Virus). People living with HIV can stay healthy for many days. Due to the gradual loss of immunity in the body of the person suffering from this disease, he is continuously infected with various diseases and death is the last consequence of his life. AIDS was first detected in 1981, and since 1985 the World Health Organization has recommended blood transfusions only after blood transfusions have been screened for HIV before transfusion. So far, 90 percent of AIDS cases have been reported in developing countries. In 2006, the number of people living with HIV worldwide was about 3.32 million. About 3 lakh 30 thousand of them are under 15 years of age. In 2006, 21 lakh people died of AIDS. Every day 6,600 people or 263 people are being infected every hour in the world. Outbreaks appear to be exacerbated in India , Myanmar and other parts of the world. So we are in a very risky geographical location. Sources of HIV infection 1. Through unprotected sexual intercourse (female to male) / Homosexuality 63.10 percent 2. Through unprotected / abnormal sexual intercourse (male-60 percent , female- female) / homosexual 0.60 percent 3. 1.30 percent through husband and wife 4. Intravenous drug users 8.20 percent 5. Blood circulation is 8.90 percent. 0.60 percent of blood components. Others (from infected pregnant mothers to newborns , through breast milk, etc.) AIDS is spread through the HIV virus through 100% blood transfusion. A woman , man or child who receives blood from a blood donor infected with the HIV virus has a 100 percent chance of contracting AIDS. A blood donor is less likely to be infected with the HIV virus because of a blood donation. This is because the equipment required for blood collection at the government-approved Transfusion Medicine Center is always sterile and used only once. Accessories are discarded after use. A blood recipient must be able to find out if he or she has had an HIV screening test to make sure his or her blood is free of HIV. It is important to note here that the HIV virus cannot be diagnosed directly by this screening test , only the antibodies that are produced in the body due to the presence of this virus can be detected . It takes 2-24 weeks for antibodies not to be produced immediately after the virus enters the human body. This period is called the window period of the virus. If an HIV-infected blood donor stays in this window period, antibodies will not be found or will be negative in the screening test, but the recipient is likely to be infected with the HIV virus. Therefore, when counseling a blood donor, one should be very careful about the information and if there is a risky blood donor or if the screening test is suspicious, blood should not be taken from him or if blood has already been collected, it should be destroyed. Symptoms of this disease can be seen in the body of an infected person through blood transfusion after 3-5 years , but the symptoms of this disease can be seen in the body of an infected person in any other way after 8-12 years or even later. The disease is more common in people aged 15-45 years. Once the HIV virus enters the body, the white blood cells attach to T-lymphocytes and enter the cell. The RNA of the virus is then converted into DNA by an enzyme. The DNA of the virus is linked to the DNA of human T-lymphocytes. It stays in that cell for the rest of its life and gives rise to numerous viruses, which once destroy the cell and come out again to attach to new T-lymphocytes. In this way the amount of virus in the body of the infected person increases and on the other hand the amount of T-lymphocytes decreases. As a result, the body's immune system is weakened. Opportunity of the body spreads various diseases and the infected person suffers from various diseases. The HIV virus infects the human body and destroys the body's immune system in stages. As a result, common pathogens give rise to various diseases in the immune system , such as fungal infections , tuberculosis , cancer, etc. Within a few weeks after the HIV virus enters the body, there is a flu-like fever , headache , and a slight body ache.
