Aids

Introduction:

Attention: Do you know how many people died from AIDS everyday or how many children have become orphan because of AIDS?

Importance: AIDS or Immunodeficiency Syndrome is a fatal disease from a virus name HIV. This disease has no cure and exist since 1980.

Credibility : Being concerned by AIDS and its consequences I decided to get some informations about this disease.

Preview: I hope to give you a general idea of what AIDS looks like. I am going to share three things about AIDS with you . I will talk about how to get HIV, the different steps of evolution of the virus in the body and the damages of AIDS.

Transition: According to the united national program on AIDS and HIV there are 40 million of people who live with AIDS or HIV worldwide and many among them do not know their serology. For these reasons I was curious to know more thinks about this disease.

BODY

I.

I will begin to unwrap my information about AIDS by telling you the major transmission of the virus.

A) Unprotected sex is the transmitter number 1 of AIDS and HIV. Having sex with anyone without protection can lead to HIV. The genitalia of both men and women are among the most germridden areas of the body and the lining of the anus and rectum is extremely thin and is filled with small blood vessels that can be easly injured during intercourse. So, oral sex will transmit the infection faster than most other methods

B) Additionally, the use of drug is also an important transmitter of AIDS. Sharing of drug needless is the most common transmission needless to say, the needle goes into the blood stream of one person and then if the needle is shared with other people, germs and infections from one person are spread to the others.

C)

In addition to the two first methods of contracting the virus HIV we have also the transmission to the fetus. This transmission can occur transplacentaly and less often by exposure to blood and vaginal secretion at delivrery and /or via breast milk. The perinatal transmission ranges between 14% and 40%.

D)

Finally, blood is also an important transmitter of AIDS .Around 5% of the AIDS cases in the world are estimated to have occurred through blood or blood products. Blood is a very efficient means of transmitting HIV infection. The frequency of seroconversion after transfusion of HIV-infected blood is very high, over 90%. After the HIV antibody test became available in 1985, the risk of getting HIV infection from blood transfusion was virtually eliminated in developed countries with the establishment of universal screening of blood donations. The risk was further reduced by the development of highly sensitive test kits and by such other means as donor selection, donor deferral and appropriate use of blood.

Transition: Now that we know how to contract HIV, let talk about its progression in the body.

II.

Many people do not develop symptoms after getting infected with HIV. Some people have a flu-like illness within several days to weeks after exposure to the virus. We can separate the development of virus in three steps.

A)

The first step is called the primary infection. In this step the lymphocyte 4 (CD4) are normal. The period of this phase is 3 to 6 months after contracting the virus .when you take a test for HIV in this period your result is negative and in this period you can propagate the virus.

B)

the second step is called the incubation period. Following initial infection, you may have no symptoms. The progression of disease varies widely among individuals. This state may last from a few months to more than 10 years. During this period, the virus continues to multiply actively and infects and kills the cells of the immune system. The immune system allows us to fight against the bacteria, viruses, and other infectious causes. The virus destroys the cells that
