Technical scheme for the treatment of AIDS with Nano-tea

6.What is the transmission route of AIDS?
It is important to understand the transmission route of AIDS. It will help human being to understand how to prevent AIDS, avoid unnecessary dread of AIDS and discrimination against AIDS patients. For example, many Chinese non-medical persons working in Zambia go to Chinese medical group and ask the question that whether a person bitten by mosquito may be infected with AIDS, because everybody living there may be bitten by mosquito. The most convincing answer no is that if mosquito could transmit AIDS, all Africans would have been infected, because everyone has the opportunity to be bitten by mosquito. At present, according to studies, experiences and epidemiologic survey, the transmission routes of AIDS have been made basically clear, and can be divided into sexual contact transmission, blood contact transmission and Mother-to-child transmission.
6.1 Sexual contact transmission
Sexual contact is the main route of HIV transmission both in the intercourse of homosexual and heterosexual. In the scope of the whole world, HIV is transmitted mostly through heterosexual intercourse.
In North America and Europe, sex between menC intercourse through anal is the major transmission form of AIDS, and the males of homosexual and bisexual constitute the main group of HIV infection. In 1980s, it was found that the patients with AIDS in the United States were mainly male homosexual population. The intercourse through anal between male homosexual population is likely to damage the mucous membranes in the anal and rectum, and open a channel for the semen and secretion that contain a lot of HIV to enter the blood through damaged mucous membranes. In addition, male homosexual often change his sexual partners, and some homosexual population have dozen or hundred sexual partners, and this increases the opportunity of HIV infection.
In Africa, Latin America and Southeast Asia, most AIDS are transmitted by sexual intercourse through vaginal, and the ratio between male and female is 1:1. The heterosexual transmission of HIV can be divided into male to female and female to male, and in these two routes, the risk of male to female transmission is higher than that of female to male transmission. Both semen and cervical secretion may carry HIV. According to anatomical analysis, the cervical secretion can stay in the body of female and not in the body of male, therefore, the exchange between semen and cervical secretion is much effective in the transmission from male to female. In some countries of Africa, there is custom that when a husband dies, his wife can be inherited by his brother, with the purpose of preventing the family property from loss. But in current Africa where AIDS is rampant, when a man inherits his brothers wife, he also inherits at the same time a deadly dowry C HIV, and the wife with HIV positive will transfer the viruses to the brother of her husband.
Prostitution and whoredom play an important role in the transmission of AIDS. The whoremaster who carries viruses will infect prostitutes and the prostitutes will transfer the viruses to other whoremaster. If anyone of them suffers from venereal diseases, the opportunity of HIV transmission will increase dramatically. The erosion and ulcer of the genitalia will open a channel for viruses to enter the blood, and the man whose genitalia has ulcer will be much more likely infected by HIV. In East Asia, Prostitution and whoredom are spread unchecked, leading to the rapid transmission of HIV. For example, HIV infection rate has increased at a surprising speed in Thailand since 1990.
Bisexual man is extreme danger both to his male sexual partners and female sexual partners. As many of them are married and may often visit prostitutes, the bisexual man may transmit HIV he gets from homosexual people to the heterosexual people, and thus both the homosexual and heterosexual of bisexual men are important in the transmission of HIV.
The major sexual behavior related to HIV transmission is intercourse through vaginal and anal, with only a few cases through month having been reported It is generally believed that sexual behavior through month is less dangerous, but if erosion and ulcer exist in the mucous membrane of mouth, the risk of HIV transmission through mouth intercourse will significantly increase.
6.2 Blood transmission
Sharing HIV- contaminated injecting equipment, transfusion with contaminated blood or blood products and transplant of HIV-contaminated tissue and organ all belong to blood transmission.
Intravenous drug injection is the second reason of HIV infection in USA and Western Europe, and in some cities in the south of China, it is the major route of AIDS transmission. HIV transmission is mainly due to sharing contaminated needles, syringes and other tools carries-on for injection. At the same time, most drug addicts are sexual activists, and a lot of HIV infection cases result from sexual behavior. They conduct sexual deal or prostitution for money to buy drug. Study shows under normal conditions in hospital, the probability of HIV infection through a simple sticking of HIV-infected needle into the skin is only 0.3%. But injecting drug user always uses repeatedly an injector, in which blood borne HIV can live for 15 days under room temperature. If other drug takers use the same injector, they will be infected, and along with the increase of the people sharing unclean injecting equipment, the risk of HIV infection will increase. On the other hand, after taking drugs, sexuality will be strengthened, and if exchanging sex for drugs, it will further increase the risk of HIV infection.
Transfusion of unscreened blood and blood products is an important route of HIV transmission at the primary stage of AIDS spread. With the development of modern medicine, Transfusion of unscreened blood and blood products is more and more broadly applied, and has saved the life of numberless patients. However if HIV-contaminated blood or blood products is transferred into the body, HIV will enter the bloodstream. VIII gene condensed agent, a content of blood is abstracted from the plasma provided by many blood donors, and therefore, it has much more opportunities of being infected by HIV. In earlier 1980s, 6% of blood donors in the United States are HIV carriers, and the VIII gene condensed agent produced there had caused infection to patients with hemophilia all over the world. In France, a blood center was contaminated by HIV, leading to thousands health people being infected by AIDS. These bitter lessons should be taken. Now the test and selection of blood donors are undertaken in many developed countries, and in our country, the management of blood donors and blood products is also strengthened. It is not possible at present to conduct HIV antigen test for every blood donor, because the equipment for the test is very complicated and expensive. Therefore, it should be careful in Transfusion of blood and blood products.
Organ transplant is also an important development of modern medicine, with which many diseases in the heart, lungs, liver and kidney at late stage can be cured. However, the organs donated have latent risk of HIV infection and American Disease Control center reported that several cases of HIV infection had occurred in the transplant of kidney, liver and bone marrow.
6.3 Mother-to-child vertical transmission
AIDS suffered by child because of mother-to-child transmission was reported as far as in 1982. This transmission can happen during pregnancy, childbirth or breastfeeding.
A pregnant woman who is HIV-positive can pass the virus on to her embryo through the placenta. Study shows that HIV can be separated from embryo aborted 8 weeks after pregnancy. But the transmission rate depends on the development stage and immune function of the mother, such as T4 lymphocyte count. The HIV infection of the embryo in the womb will influence the development of the embryo, lead to abortion or AIDS of the embryo once born. The earlier the embryo is HIV-infected in the womb, the easier the abortion happens or the larger the influence is to the development of the embryo, and the earlier the relevant AIDS symptoms appear, the shorter the newborn will survive. In Endola Pediatric Hospital of Zambia, 265 cases of newborns with HIV/AIDS were treated from 1989 to 1993, among them, 86% were ill, including sapraemia, bronchus, deep jaundice and skin damage 3 weeks after born, 74.4% died of illness. The newborns who were ill 1 month after born usually survived not over 6 months. Mother-to-child transmission may also happen in the course of delivery through vagina. If the skin or mucous membrane of the embryo is damaged during the delivery, the blood born HIV in mothers body will enter the bloodstream of the baby through the wound. Study shows that cesaream birth can reduce HIV infection through mother-to-child transmission.
Viruses can be separated from the breast milk of infected mother, and breastfeeding can transmit HIV to baby. There is a report that a mother has been infected by HIV during blood transfusion after labor, and her baby has been also infected by HIV after taking her breast milk for 6 months. However, the probability of infection through breastfeeding is not yet clear. American health authorities have advised HIV-infected mothers not feed their babies with breast milk. In many countries of Africa, due to backward in economy and lack of substitutes for breast milk, termination of breastfeeding will lead to severe malnutrition that endanger much more seriously the survival of babies, breastfeeding by HIV-infected mothers is still advocated. The measure to avoid mother-to-child transmission is to persuade HIV-infected women not to bear and terminate pregnancy if found. Because of being infected at fetal stage, many babies die within 3 years after birth, and the survivors will become children suffered from diseases and orphans without mother. This involves many problems in terms of ethics, morality and sentiment What is the spreading trend of AIDS?
According analysis on retrospective materials, until 1970s, HIV was not known and was spreading over the world from a unknown origin. In 1960s, there was report about emaciate syndrome from Uganda, the symptoms reported of which are basically similar to the AIDS at present. As the number of disease was very small, and the symptoms appeared usually several years after being infected, this period of spread is called still stage of HIV infection.
The stillness ended in 1981 when AIDS was first reported, and then there were reports about AIDS in America, Europe, Oceania and Africa. Most AIDS patients in USA and England (80% in England, 60% in USA) were homosexual population and Bisexuals. The spread of AIDS in this period is referred to as the first high tide. After AIDS was reported, USA and many countries in Europe paid great attention to it, put in a lot of capital and technical force found out the causative agent, transmission route and pathogenesis within 2-3 years, strengthened propaganda and education and taken a series of measures within the High risk population, such as changing dangerous sex behavior and adopting condoms, leading to significant reduction of dangerous sexual behavior of homosexual group and gradually slowing down the trend of HIV infection. Since 1986, 50%-90% of homosexual men in San Francisco and New York of USA have given up anal sex or use condoms in anal sex.
The second high tide of HIV infection is the involvement of intravenous drug users. They are the second largest component of HIV infection. Most the drug takers are sexual activists (including homosexual population and heterosexuals) and it is difficult to determine whether they are infected through sex or intravenous injection.
The third high tide of HIV infection is the transmission through bisexual between male and female. Owing to the infection of women, more and more HIV-infected babies are born.
As a general trend, another high tide of AIDS spread throughout the world is ahead. The number of women and children suffered from AIDS is increasing and the thread to the mankind is becoming serious day by day. Global united action should be taken to mobilize all forces in various aspects, make use all the existing technology and conditions, strengthen propaganda and education, avoid dangerous sexual behavior and block the transmission route of HIV. This is the only way to prevent new infection from happening before effective vaccines and specific effective drugs are developed.
