HIV and AIDS Essay

HIV is a human immunodeficiency virus that causes AIDS. HIV is a group of viruses that infect human cells and use retroviruses to propagate and propagate energy and nutrients provided by these cells. AIDS (Acquired Immune Deficiency Syndrome) uses other diseases that the body's immune system collapses, can not resist certain infections known as "opportunistic infections" and is weakened by the immune system It is a disease. When a person is infected with HIV, the virus enters the body and survives, and it grows on white blood cells. These are usually immune cells that protect us from disease.

Most of them do not know that they are infected with HIV and that they may spread the virus to others. In the United States, nearly one million people are infected with HIV or AIDS, or one in 250 people is infected with HIV. In the United States at least 40,000 Americans are newly infected with HIV every year, but it is estimated that half of people infected with HIV are not tested and do not know that they are infected with virus It has been.

Since the epidemic of AIDS, AIDS has delivered more than 30 million deaths worldwide, of which over 500,000 are Americans. AIDS replaced malaria and tuberculosis as the world's most deadly infectious disease, the fourth most common cause of death in the world. With this epidemic, over 13 million children have become orphans. People living with HIV have viruses in body fluids such as blood, semen, vaginal secretions, breast milk. This virus spreads only when HIV-infected liquid enters the blood of another person. This direct invasion can occur via (1) through the opening in the vagina, rectum, the oral lining and the penile tip; (2) intravenous injection using a syringe; or (3) through rupture of the skin such as incision or pain It can happen. Normally, HIV will proceed as follows.

AIDS and HIV AIDS and AIDS are sexually transmitted diseases. HIV and AIDS can spread in several different ways. Some of these methods include intercourse, sharing of needles and fluids. You can not get AIDS or HIV from insect bites, blood donation, accidental contacts. People think that AIDS and HIV come from monkeys. If you do not know that you have AIDS, HIV will be AIDS. It takes about ten years for AIDS to become AIDS. That is why it is important to test this disease. - The desire to have sex is the result of the spread of infectious diseases such as AIDS and AIDS all over the world. The impulse to satisfy sexual desire and desire is the main reason that HIV / AIDS spread by gender. As far as Mexico is concerned, males are primarily responsible for the spread of infectious diseases due to homosexual activity during work in the United States.

HIV / AIDS is currently incurable. UNAIDS Agency (UNAIDS) states that HIV is the "root cause" of AIDS and "there is no doubt". HIV was isolated from 1983 to 1984 and was identified as a source of AIDS. HIV destroys blood cells called CD4 + T cells. This is essential for the human immune system to function properly. Research on thousands of people shows that most people living with HIV have viruses for years and then damage enough immune system to develop AIDS.

The term AIDS applies to the most advanced stage of HIV infection. The current definition of AIDS includes all HIV-infected individuals with less than 200 CD4 + T cells (healthy adults usually have about 800 or more CD4 + T cell numbers). In addition, the definition includes those who have been diagnosed with HIV, who have one or more clinical symptoms (including opportunistic infections and certain cancers) that affect patients with advanced HIV disease . Some people become sick like influenza within a month after being infected with the HIV virus. However, many people did not show any symptoms in the first infection. In addition, the actual symptoms (which usually disappear within a week to within a month) are often mistaken for another virus infection. These include:
