The HIV virus to produce disease in the normal process of development and proliferation must have access and enter the bloodstream of our body.

When abroad, outside the conditions suitable to his life, the virus dies quickly in minutes.

Under these conditions, and already know what they are infectious body fluids, the forms of transmission of AIDS are:

1. BLOOD - products and their derivatives

Years ago, when he was not aware of the disease, it was possible to have injected blood or blood derived from patients already suffering from AIDS in healthy subjects and sends them to the disease.
Fortunately this situation is now resolved. In the analysis that, necessarily, that are made for blood donors, is in the carrier screening for AIDS
It is a form of transmission that currently only by rare accident, may be considered.

2. INJECTIONS IN VEIN

If the product is injected which is sterile but the needle and syringe used in the injection are infected, the disease is also transmitted. In health establishments there is no such risk because the needles and syringes are sterile and used only once. But among addicts, who acts carelessly practice, sharing of needles and syringes without the least care, is one of the most important factors for transmission. Associated with multiple sexual practices and not protected, drug addicts become one of the most infested groups and the largest disseminator of infection in the general population.

3. SEXUAL RELATIONS

The cases of AIDS were first detected there, as more often among gay men. This group still considered high risk, because it had been the most attacked and warned more was the one who earlier had to know and face the illness, taking precautions to defend a convenient no contamination. In contrast, transmission through heterosexual sex has increased greatly in recent years.

1. WITH THE NUMBER OF SEXUAL PARTNERS
   
2. SENSE MAN INFECTED WOMEN HEALTHY

The existence of small lacerations, ulcers or sores in the vaginal wall, rather aggravate the possibility of infection of women.
Small lesions in women infected causing greater ease of contamination in healthy men.
If we consider that there are situations of daily practice of various acts of sexual activity with several different partners, even among individuals who may not know your situation as patients, it is understandable why it is considered now as very important heterosexual transmission.

AIDS IS NO LONGER A DISEASE OF CLOSED GROUPS SUCH AS ADDICTS OR GAYS TO BE A DISEASE THAT CAN REACH ANY ELEMENT OF THE POPULATION.
There are countries where it begins to be alarming incidence of AIDS amongst the young population (12, 13 years), related to the initiation of an unbridled sexual activity and practice of drug use.

4. PREGNANCY

INFECTED WOMEN MAY TRANSMIT AIDS TO YOUR CHILDREN.

The most common transmission is made during the period of gestation when the mother's blood will circulate in the foetus through the placenta. Less likely, or less frequent, is contamination by blood lost during childbirth and during breastfeeding. Newborns have a very low resilience and undeveloped and the resistance they have during the early life they were transmitted by the mother during pregnancy. An infected mother has little to offer his son. Bit of good, of course. Because it offers is dependent on the state of progress of his illness and because not all children are affected the same way.
In general, it can be assumed that 20% of children of infected mothers not treated will have AIDS and die in the short term. Some two years before they have, others will have many diseases and complications, dragging a painful and miserable life until he died some years later.

CHILDREN BORN WITH AIDS IN ALL COUNTRIES, CHILDREN OF PARENTS THAT DO NOT KNOW WHAT CARRIERS OF DISEASE WERE INEVITABLY DOOMED YOUR CHILDREN.
