HUMAN IMMUNODEFICIENCY VIRUS

Human Immunodeficiency Virus

Human Immunodeficiency Virus

Introduction

The cause of the disease known as AIDS (HIV) infection is defeated organizmavirusom human immunodeficiency. Suffer in the first place, immune system cells, which lose their primary function - protecting the body against diseases.

In 2002, HIV infection was detected for the first time, the virus has long been studied, and it is now known more than about any other virus that attacks the human body. Immunodeficiency virus belongs to the lentivirus (slow acting), the group - retrovirusy. Izobrazhenie virus similar to the anti-mine, on the surface of which are "Glycoprotein mushrooms" - an instrument with which the virus enters the T-lymphocytes (cells in human blood). (Konde- Lule , 2011) At the core of T-lymphocyte contains genetic information 100 000 times greater than in the virus, but, nevertheless, the cell is unable to resist the virus and begins to slowly crumble from its damaging effects.

Interviewee's condition pre-onset

Almost all the genetic information known in the nature of the cells of viruses is encoded in the form of DNA. In human immunodeficiency virus is encoded in RNA. HIV is able to use transcriptase enzyme to translate their RNA into DNA, so the cell, which penetrates the virus takes the foreign DNA. This process takes about 12 hours after infection. After this process is irreversible, because the DNA of the virus begins to manage the human immune system, and by the time when HIV infection is transformed into AIDS, a large number of cells contains the genetic material of the virus. Despite the detailed scrutiny of HIV, many moments of HIV infection is not entirely clear - namely, what is the mechanism of the destructive effects of the virus on the immune system, and why many people infected with HIV may be a long time to stay completely healthy. (Weiss , 2003)

Does AIDS really human immunodeficiency virus? The medicine has not yet come to a view, but more than 5000 scientists around the world have signed the Durban Declaration, reaffirming the fact that HIV is the cause of razvitiya SPIDa.

Onset Disease Progression & Body Response

Since there is no one symptom that is unique to HIV infection, based on the complaints of the patient to diagnose HIV infection is impossible. The need for an HIV test caused by the fact that public opinion relates to the very possibility of contracting HIV and AIDS become ill as a death sentence. Therefore, it often happens that after a casual sexual intercourse without a condom, the man begins to carefully "listen" to your body, "finding" more and more symptoms of this dreadful disease.

A blood test for antibodies to HIV is taken from a vein. In our medical center, you can be diagnosed HIV anonymously. We have conducted and rapid HIV tests.

During pregnancy, a blood test for AIDS is made compulsory. The presence or absence of antibodies and concluded on the presence or absence of same in the patient's immunodeficiency virus (Greener, 2002).

ELISA can be done not once, but only some time ...
