Finding a Doctor HIV is a virus that lives in human bloodsexual fluids, and breast milk. It weakens your immune systemso your body has a hard time fighting off common germs, viruses, fungi, and other invaders. It spreads mainly through unprotected sexual contact and sharing needles.
Early in the U. Early cases of HIV infection that were sexually transmitted often were related to the use of alcohol and other substances, and the majority of these cases occurred in urban, educated, white MSMs. Currently, injection drug users represent the largest HIV-infected substance-abusing population in the United States.
The virus is transmitted primarily through the exchange of blood using needles, syringes, or other IDU equipment e. Lack of knowledge about safer needle use techniques and the lack of alternatives to needle sharing e.
Another route of HIV transmission among injection drug users is through sexual contacts within relatively closed sexual networks, which are characterized by multiple sex partners, unprotected sexual intercourse, and exchange of sex for money Friedman et al.
Substance abuse increases the risk of contracting HIV. HIV infection is substantially associated with the use of contaminated or used needles to inject heroin.
Also, substance abusers may put themselves at risk for HIV infection by engaging in risky sex behaviors in exchange for powder or crack cocaine.
However, this fact does not minimize the impact of other substances that may be used e. Substance abusers are at risk for HIV infection through sexual behaviors. Both men and women may engage in risky sexual behaviors e. Substance abuse treatment serves as HIV prevention. Placing the client in substance abuse treatment along a continuum of care and treatment helps minimize continued risky substance-abusing practices.
The second part of the chapter presents a summary of epidemiological data from the CDC. A recent study Gao et al. The researchers believe that the virus crossed over from monkeys to humans when hunters became exposed to infected blood.
Tracking of the disease in the United States began early after the discovery of the pandemic, but even to date, tracking data reveal only how many individuals have AIDS, not how many have HIV.
Many States are counting HIV cases now that positive results are to be gained by treating the infection in the early stages and because counting only AIDS cases is no longer sufficient for projecting trends of the pandemic. However, because HIV-infected people generally are asymptomatic for years, they might not be tested or included in the count.
The decline can be attributed to advances in treating HIV with multiple medications, known as combination therapy; treatments to prevent secondary opportunistic infections; and a reduction in the HIV infection rate in the mids prior to the introduction of combination therapy. The latter can be attributed to improved services for people with HIV and access to health care.
HIV is a virus that thrives in certain ecological conditions. The following will lead to higher infection rates: These ecological conditions exist to a large degree among urban, poor, and marginalized communities ofinjection drug users.
Thus, MSMs and African American and Hispanic women, their children, and adolescents within these communities are at greatest risk. HIV must be transmitted directly from one person to another through human body fluids that contain HIV-infected cells, such as blood, semen, vaginal secretions, or breast milk.
The most effective means of transmitting HIV is by direct contact between the infected blood of one person and the blood supply of another.Human Immunodeficiency Virus – Revised 4/15/ Page 1 of 7 HUMAN IMMUNODEFICIENCY VIRUS (AIDS/HIV TESTING) I. INTRODUCTION HIV is an RNA retrovirus that causes a chronic illness characterized by destruction of CD4 lymphocytes; over the course of .
Human Immunodeficiency Virus (HIV) infection, the cause of Acquired Immune Deficiency Syndrome (AIDS) has become a significant threat to global public health faster than any previous epidemic (Mann and Tarantola ). The genetic nature of HIV evades the development of a preventive vaccine and a cure for HIV infection remains a distant hope.
HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome or AIDS if not treated. Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment.
HIV The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to .
HIV is short for human immunodeficiency virus. The virus attacks and suppresses the immune system, making those who have it more susceptible to infections and cancer. AIDS stands for acquired immunodeficiency syndrome (a disease where the body's cellular immunity is severely damaged and thus lowers your resistance to infection and/or malignancy).
HIV is the virus that causes AIDS. Nov 14, · The virus that causes AIDS, which is the most advanced stage of HIV infection. HIV is a retrovirus that occurs as two types: HIV-1 and HIV Both types are transmitted through direct contact with HIV-infected body fluids, such as blood, semen, and vaginal fluids, or .
