HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body. This damage to the immune system makes it harder and harder for the body to fight off infections and some other diseases. Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. Learn more about the stages of HIV and how to know whether you’re infected.
A generalized graph of the relationship between HIV copies (viral load) and CD4 counts over the average course of untreated HIV infection; any particular individual’s disease course may vary considerably.
Federal and state programs are also hampered by policy decisions grounded in ideology rather than science such as the allocation of more than $1 billion to failed abstinence-only sex education programs or the enactment of outdated HIV criminalization statutes. In more than 30 states, people living with HIV can be tried and imprisoned simply because a partner accuses them of withholding their HIV status. There’s no proof these laws work, and they run counter to public health by perpetuating stigma and subsequently deterring people from getting tested or treated for HIV.
Getting the right screening test at the right time is one of the most important things a man can do for his health. Learn at what age men should be screened for prostate cancer, high blood pressure, cholesterol and other health risks.
CDC recommends routine testing for HIV infection for persons aged 13–64 years in health care settings and testing at least annually for persons at high risk for HIV infection (7). Yet, according to National HIV Behavioral Surveillance (NHBS), one third of gay, bisexual, and other men who have sex with men (MSM) have not been tested in the past year, with even lower percentages of recent testing reported among other population segments at high risk for HIV infection.
The success of ART is assessed by measuring plasma HIV RNA levels every 8 to 12 wk for the first 4 to 6 mo or until HIV levels are undetectable and every 3 to 6 mo thereafter. Increasing HIV levels are the earliest evidence of treatment failure and may precede a decreasing CD4 count by months. Maintaining patients on failing drug regimens selects for HIV mutants that are more drug-resistant. However, compared with wild-type HIV, these mutants appear less able to reduce the CD4 count, and failing drug regimens are often continued when no fully suppressive regimen can be found.
Early on a balmy morning last October, Cedric Sturdevant began his rounds along the bumpy streets and back roads of Jackson, Miss. Sturdevant, 52, has racked up nearly 300,000 miles driving in loops and widening circles around Jackson in his improvised role of visiting nurse, motivational coach and father figure to a growing number of young gay men and transgender women suffering from H.I.V. and AIDS. Sturdevant is a project coordinator at My Brother’s Keeper, a local social-services nonprofit. If he doesn’t make these rounds, he has learned, many of these patients will not get to the doctor’s appointments, pharmacies, food banks and counseling sessions that can make the difference between life and death.
Although most HIV-1 infected individuals have a detectable viral load and in the absence of treatment will eventually progress to AIDS, a small proportion (about 5%) retain high levels of CD4+ T cells (T helper cells) without antiretroviral therapy for more than 5 years. These individuals are classified as HIV controllers or long-term nonprogressors (LTNP). Another group consists of those who maintain a low or undetectable viral load without anti-retroviral treatment, known as “elite controllers” or “elite suppressors”. They represent approximately 1 in 300 infected persons.
Integrase inhibitors. Integrase inhibitors prevent the virus from inserting its own genetic material into the DNA of the infected cell. This stops the virus from replicating. Integrase was the only FDA-approved drug in this class as of early 2009. Several investigational drugs in this category were in clinical trials at that time.
All of the NNRTIs are associated with important drug-drug interactions so they must be used with caution in patients on other medications. There are numerous resources available to patients on these medications to make sure that they do not adversely interact with other HIV or non HIV-related drugs.
Painful rash at the injection site and allergic (hypersensitivity) reactions (including rash, fever, chills, nausea, and low blood pressure), numbness and tingling in the hands and feet (peripheral neuropathy), insomnia, and loss of appetite
Not everyone who has HIV have AIDS. When people first get HIV, they can be healthy for years. A person is diagnosed as having AIDS when he or she gets specific types of illnesses or gets sick in certain ways due to their HIV. Once a person’s HIV progresses to (or turns into) AIDS, the person will continue to have AIDS for the rest of their life. While there are many treatments for HIV/AIDS, at this point there is no cure.
Side effects associated with EFV are mostly dizziness, confusion, fatigue, and vivid dreams. These tend to be most prominent during the first weeks of therapy and then often decrease in severity. It is generally recommended that EFV be taken at bedtime so that the patient is asleep during the time dizziness and confusion may be most severe. It is also noteworthy that there may be an increased risk of depression associated with the use of this drug, and it should be used with caution in those with poorly managed depression. Rash and liver inflammation can occur with both EFV and DLV, and these drugs may also be linked to abnormalities of lipids in the blood.
Ultimately, HIV causes AIDS by depleting T cells. This weakens the immune system and allows opportunistic infections. T cells are essential to the immune response and without them, the body cannot fight infections or kill cancerous cells. The mechanism of CD4+ T cell depletion differs in the acute and chronic phases. During the acute phase, HIV-induced cell lysis and killing of infected cells by cytotoxic T cells accounts for CD4+ T cell depletion, although apoptosis may also be a factor. During the chronic phase, the consequences of generalized immune activation coupled with the gradual loss of the ability of the immune system to generate new T cells appear to account for the slow decline in CD4+ T cell numbers.
A transmissible retrovirus that causes AIDS in humans. Two forms of HIV are now recognized: HIV-1, which causes most cases of AIDS in Europe, North and South America, and most parts of Africa; and HIV-2, which is chiefly found in West African patients. HIV-2, discovered in 1986, appears to be less virulent than HIV-1, but also may have a longer latency period.

Sackoff et al found that between 1999 and 2004, the HIV-related mortality rate in New York City decreased each year by approximately 50 deaths per 10,000 people with AIDS. The rate of non–HIV-related deaths also showed a decline, more modest but consistent, with about 7.5 fewer deaths per 10,000 people with AIDS per year. 
You don’t actually “get” AIDS. You might get infected with HIV, and later you might develop AIDS. You can get infected with HIV from anyone who’s infected, even if they don’t look sick and even if they haven’t tested HIV-positive yet. The blood, vaginal fluid, semen, and breast milk of people infected with HIV has enough of the virus in it to infect other people. Most people get the HIV virus by:
“Resistance occurs when the virus replicates in the presence of the drugs,” said Dr. Stephen Boswell, president and CEO of Boston’s Fenway Health, a healthcare organization that works with lesbian, gay, bisexual and transgender people. “Missed dosages lead to lower concentrations in the bloodstream and in the body, so the virus can become resistant and spread. So staying on your medications and not missing dosages is absolutely critical.”
HIV may be the human version of simian immunodeficiency virus (SIV), known to infect African chimpanzees. It may have crossed over and mutated in humans who ate infected chimpanzee meat as long ago as the late 1800s.

From the time of infection by HIV, AIDS normally develops within ten years, though there are now drugs which may be used to extend this time. The immune failure, which is characteristic of AIDS, occurs as a consequence of a gradual decline in the number of CD4 T lymphocytes. Eventually the infected person succumbs to a variety of infections by BACTERIA, FUNGI, protozoa or viruses and/or develops a cancer(s) such as Kaposi’s Sarcoma.
Abstinence-only adherents think being less frank is being more responsible. They view sexuality as a moral issue properly left for parents to discuss with their children and one that lies beyond the responsibilities of schools. The conservative columnist Cal Thomas spoke for this viewpoint when he argued that parents “have lost a significant right to rear their children according to their own moral standards.” Other objections come from religious conservatives who oppose any neutral or positive discussion of homosexuality. Koop, for example, was blasted for allegedly “sponsoring homosexually oriented curricula” and “teaching buggery in the 3rd grade.” In addition to voicing moral objections, critics say comprehensive sex ed. is generally a failure because it encourages a false sense of security among teens that leads to experimentation with sex or drugs. “We have given children more information presumably because we think it will change their behavior, and yet the behavior has gotten worse, not better,” said Gary Bauer, president of the Family Research Council.

These drugs prevent HIV from replicating in cells and dramatically reduce the amount of HIV in the blood over a few days to weeks. If replication is sufficiently slowed, the destruction of CD4+ lymphocytes by HIV is decreased and the CD4 count begins to increase. As a result, much of the damage to the immune system caused by HIV can be reversed. Doctors can detect this reversal by measuring the CD4 count, which begins to return toward normal levels over weeks to months. The CD4 count continues to increase for several years but at a slower rate.
It is strongly advised that individuals on an antiviral regimen not miss any doses of their medications. Unfortunately, life is such that doses often are missed. Reasons for missing doses range from just forgetting to take the medication, leaving town without the medication, or because of a medical emergency, such as the need for urgent surgery. For example, after an appendectomy for acute appendicitis, a patient may not be able to take oral medication for up to several days. When a dose is missed, the patient should contact his or her physician without delay to discuss the course of action. The options in this situation are to take the missed doses immediately or simply resume the drugs with the next scheduled dose.
According to the August 2008 report issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS), as of 2007, approximately 33 million people worldwide are HIV positive. Over half of the 33 million are women and this statistic has remained stable for several years. The highest number of cases is found in sub-Saharan Africa and Southeast Asia.

In 2008 in the United States approximately 1.2 million people were living with HIV, resulting in about 17,500 deaths. The US Centers for Disease Control and Prevention estimated that in 2008 20% of infected Americans were unaware of their infection. As of 2016 about 675,000 people have died of HIV/AIDS in the USA since the beginning of the HIV epidemic. In the United Kingdom as of 2015 there were approximately 101,200 cases which resulted in 594 deaths. In Canada as of 2008 there were about 65,000 cases causing 53 deaths. Between the first recognition of AIDS in 1981 and 2009 it has led to nearly 30 million deaths. Prevalence is lowest in Middle East and North Africa at 0.1% or less, East Asia at 0.1% and Western and Central Europe at 0.2%. The worst affected European countries, in 2009 and 2012 estimates, are Russia, Ukraine, Latvia, Moldova, Portugal and Belarus, in decreasing order of prevalence.
AIDS is an acquired immunodeficiency syndrome defined by a severe depletion of T cells and over 20 conventional degenerative and neoplastic diseases. In the U.S. and Europe, AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T cells. Consequently, the virus was termed human immunodeficiency virus (HIV), and antibody to HIV became part of the definition of AIDS. The hypothesis that HIV causes AIDS is examined in terms of Koch’s postulates and epidemiological, biochemical, genetic, and evolutionary conditions of viral pathology. HIV does not fulfill Koch’s postulates: (i) free virus is not detectable in most cases of AIDS; (ii) virus can only be isolated by reactivating virus in vitro from a few latently infected lymphocytes among millions of uninfected ones; (iii) pure HIV does not cause AIDS upon experimental infection of chimpanzees or accidental infection of healthy humans. Further, HIV violates classical conditions of viral pathology. (i) Epidemiological surveys indicate that the annual incidence of AIDS among antibody-positive persons varies from nearly 0 to over 10%, depending critically on nonviral risk factors. (ii) HIV is expressed in less than or equal to 1 of every 10(4) T cells it supposedly kills in AIDS, whereas about 5% of all T cells are regenerated during the 2 days it takes the virus to infect a cell. (iii) If HIV were the cause of AIDS, it would be the first virus to cause a disease only after the onset of antiviral immunity, as detected by a positive “AIDS test.” (iv) AIDS follows the onset of antiviral immunity only after long and unpredictable asymptomatic intervals averaging 8 years, although HIV replicates within 1 to 2 days and induces immunity within 1 to 2 months. (v) HIV supposedly causes AIDS by killing T cells, although retroviruses can only replicate in viable cells. In fact, infected T cells grown in culture continue to divide. (vi) HIV is isogenic with all other retroviruses and does not express a late, AIDS-specific gene. (vii) If HIV were to cause AIDS, it would have a paradoxical, country-specific pathology, causing over 90% Pneumocystis pneumonia and Kaposi sarcoma in the U.S. but over 90% slim disease, fever, and diarrhea in Africa.(viii) It is highly improbable that within the last few years two viruses (HIV-1 and HIV-2) that are only 40% sequence-related would have evolved that could both cause the newly defined syndrome AIDS. Also, viruses are improbable that kill their only natural host with efficiencies of 50-100%, as is claimed for HIVs. It is concluded that HIV is not sufficient for AIDS and that it may not even be necessary for AIDS because its activity is just as low in symptomatic carriers as in asymptomatic carriers. The correlation between antibody to HIV and AIDS does not prove causation, because otherwise indistinguishable diseases are now set apart only on the basis of this antibody. I propose that AIDS is not a contagious syndrome caused by one conventional virus or microbe. No such virus or microbe would require almost a decade to cause primary disease, nor could it cause the diverse collection of AIDS diseases. Neither would its host range be as selective as that of AIDS, nor could it survive if it were as inefficiently transmitted as AIDS. Since AIDS is defined by new combinations of conventional diseases, it may be caused by new combinations of conventional pathogens, including acute viral or microbial infections and chronic drug use and malnutrition. The long and unpredictable intervals between infection with HIV and AIDS would then reflect the thresholds for these pathogenic factors to cause AIDS diseases, instead of an unlikely mechanism of HIV pathogenesis.
