The secret to why HIV is so hard to cure lies in a quirk of the type of cell it infects. Our immune system is designed to store information about infections we have had in the past; this property is called “immunologic memory.” That’s why you’re unlikely to be infected with chickenpox a second time or catch a disease you were vaccinated against.
What happens if HIV is left untreated?
HIV treatment involves taking medicine that reduces the amount of HIV in your body. HIV medicine is called antiretroviral therapy (ART). There is no effective cure for HIV. But with proper medical care, you can control HIV. Most people can get the virus under control within six months. Taking HIV medicine does not prevent transmission of other ...

Is HIV incurable?
Despite our grim track record with the disease, HIV is probably not incurable. Although we don’t have a cure yet, we’ve learned many lessons along the way. Most importantly, we should be extremely careful about using the word “cure,” because for now, we’ll never know if a person is cured until they’re not cured.
How does HIV affect the immune system?
HIV hijacks the body's immune system by attacking T cells. Over the past two years, the phrase “HIV cure” has flashed repeatedly across newspaper headlines. In March 2013, doctors from Mississippi reported that the disease had vanished in a toddler who was infected at birth. Four months later, researchers in Boston reported a similar finding in two ...
How does HIV replication work?
HIV replication is especially hard for the body to control because the white blood cells it infects, and eventually kills, are a critical part of the immune system.
Does HIV go dormant?
White blood cells infected with HIV will occasionally transition to the dormant state before the virus kills them. In the process, the virus also goes temporarily inactive. By the time drugs are started, a typical infected person contains millions of these cells with this “latent” HIV in them.
What would happen if the latent virus was stopped?
The first would involve purging the body of latent virus so that if drugs were stopped, there would be nothing left to restart the infection. This was often called a “sterilizing cure.” It would have to be done in a more targeted and less toxic way than previous attempts of the late 1990s, which, because they attempted to “wake up” all of the body’s dormant white blood cells, pushed the immune system into a self-destructive overdrive. The second approach would instead equip the body with the ability to control the virus on its own. In this case, even if treatment was stopped and latent virus reemerged, it would be unable to produce a self-sustaining, high-level infection. This approach was referred to as a “functional cure.”
When was AZT approved?
In 1987, the FDA approved AZT as the first drug to treat HIV. With only two years between when the drug was identified in the lab and when it was available for doctors to prescribe, it was—and remains—the fastest approval process in the history of the FDA. AZT was widely heralded as a breakthrough.
Can HIV medications cause side effects?
However, not everyone experiences side effects from ART. The HIV medications used today have fewer side effects, fewer people experience them, and they are less severe than in the past. Side effects can differ for each type of ART medicine and from person to person.
Can HIV cause drug resistance?
Drug resistance can be a cause of treatment failure for people living with HIV. As HIV multiplies in the body, it sometimes mutates (changes form) and produces variations of itself. Variations of HIV that develop while a person is taking ART can lead to drug-resistant strains of HIV. With drug resistance, HIV medicines that previously controlled ...
What is the treatment for HIV?
HIV treatment involves taking medicines that slow the progression of the virus in your body. HIV is a type of virus called a retrovirus, and the combination of drugs used to treat it is called antiretroviral therapy (ART). ART is recommended for all people living with HIV, regardless of how long they’ve had the virus or how healthy they are.
Is HIV treatment a prevention?
There is also a major prevention benefit. People living with HIV who take HIV medication daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners. This is called treatment as prevention.
Can HIV be transmitted to HIV-negative people?
People living with HIV who take HIV medication daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners. This is called treatment as prevention.
How successful is HIV treatment?
HIV treatment is most likely to be successful when you know what to expect and are committed to taking your medicines exactly as prescribed. Working with your health care provider to develop a treatment plan will help you learn more about HIV and manage it effectively.
How soon can you start ART for HIV?
Treatment guidelines from the U.S. Department of Health and Human Services recommend that a person living with HIV begin ART as soon as possible after diagnosis. Starting ART slows the progression of HIV and can keep you healthy for many years.
What are the problems with HIV?
Poor drug absorption, which can happen to people with chronic HIV-associated diarrhea or other malabsorption issues. Not following food requirements, which can also affect drug absorption and metabolism. Cost and affordability, including the lack of adequate health insurance.
What happens if you fail a virologic test?
If virologic failure is declared, your doctor will order one or more tests to evaluate your "viral pool." When you have HIV, you do not have just one virus but rather a multitude of variants, some of which are drug-resistant. Under the pressure of antiretroviral therapy, the viral pool can change with drug-resistant variants becoming more and more predominant.
What is acquired drug resistance?
Acquired drug resistance, in which you "pick up" a drug-resistant variant through sex, shared needles, or other modes of transmission. Previous treatment failure, during which you will likely have developed levels of resistance to antiretrovirals of the same class. High baseline viral load, as some drug regimens are less effective ...
What is the first step in treatment failure?
If treatment failure occurs, the first step is to identify the factors that may have contributed directly or indirectly. In most cases, the failure will be the result of poor drug adherence, wherein medication doses were frequently missed or treatment was interrupted.
Is HIV treatment prevention?
Large research studies with newer HIV medications have shown that treatment is prevention. These studies monitored thousands of male-female and male-male couples in which one partner has HIV and the other does not over several years. No HIV transmissions were observed when the HIV-positive partner was virally suppressed.
How long does it take for HIV to be undetectable?
Almost everyone who takes HIV medication daily as prescribed can achieve an undetectable viral load, usually within 6 months after starting treatment. There are important health benefits to getting the viral load as low as possible. People living with HIV who know their status, take HIV medication daily as prescribed, ...
How does HIV medication help?
In addition to preventing sexual transmission of HIV there are other benefits of taking HIV medication to achieve and maintain an undetectable viral load: 1 It reduces the risk of mother-to-child transmission from pregnancy, labor, and delivery. If a woman living with HIV can take HIV medication as prescribed throughout pregnancy, labor, and delivery and if HIV medication is given to her baby for 4-6 weeks after delivery, the risk of transmission from pregnancy, labor, and delivery can be reduced to 1% or less. Scientists don’t know if a woman living with HIV who has her HIV under control can transmit HIV to her baby through breastfeeding. While it isn’t known if or how much being undetectable or virally suppressed prevents some ways that HIV is transmitted, it is reasonable to assume that it provides some risk reduction. 2 It may reduce HIV transmission risk for people who inject drugs. Scientists do not yet know whether having a suppressed or undetectable viral load prevents HIV transmission through sharing needles or other injection drug equipment, but it is reasonable to assume that it provides some risk reduction. Even if you are taking HIV medication and are undetectable, use new equipment each time you inject and do not share needles and syringes with other people.
Why is it important to take HIV medication?
Taking HIV Medication to Stay Healthy and Prevent Transmission. If you have HIV, it is important to start treatment with HIV medication (called antiretroviral therapy or ART) as soon as possible after your diagnosis. If taken every day, exactly as prescribed, HIV medication can reduce the amount of HIV in your blood (also called the viral load) ...
Can HIV be transmitted to HIV-negative people?
People living with HIV who take HIV medication daily as prescribed and get and keep an undetectable viral load have effectively no risk of sexually transmitting HIV to their HIV-negative partners.
Can HIV be transmitted through breastfeeding?
Scientists don’t know if a woman living with HIV who has her HIV under control can transmit HIV to her baby through breastfeeding . While it isn’t known if or how much being undetectable or virally suppressed prevents some ways that HIV is transmitted, it is reasonable to assume that it provides some risk reduction.
Why is it called viral suppression?
It is called viral suppression because HIV medication prevents the virus from growing in your body and keeps the virus very low or “suppressed.”. Viral suppression helps keep you healthy and prevents illness.
When did HIV become a cause of AIDS?
At the beginning of the 1980s, before HIV had been identified as the cause of AIDS, the infection was thought to only affect specific groups, such as gay men in developed countries and people who inject drugs.
Is stigma a barrier to HIV?
Stigma remains a fundamental barrier in fighting HIV, believes HIV-positive ABC news broadcaster Karl Schmid, who says that “much of the fear and stigma that surrounded the AIDS epidemic of the 1980’s and 1990’s still exists. Many people still believe that it is a death sentence”.
What was the HIV epidemic in the 1980s?
Fear, stigma and ignorance. That is what defined the HIV epidemic that raged through the world in the 1980s, killing thousands of people who may only have had a few weeks or months from diagnosis to death - if they even managed to be diagnosed before they died. “With no effective treatment available in the 1980s, ...
How many people have died from HIV?
Since the beginning of the epidemic, more than 70 million people have acquired the infection, and about 35 million people have died. Today, around 37 million worldwide live with HIV, of whom 22 million are on treatment. When World AIDS Day was first established in 1988, the world looked very different to how it is today.
When was the first HIV test conducted?
The HIV virus was first isolated by Dr Françoise Barré-Sinoussi and Dr Luc Montagnier in 1983 at the Institut Pasteur. In November that year, WHO held the first meeting to assess the global AIDS situation and initiated international surveillance.
Who started World AIDS Day?
In 1988, two WHO communications officers, Thomas Netter and James Bunn, put forward the idea of holding an annual World AIDS Day, with the aim of increasing HIV awareness, mobilising communities and advocating for action worldwide. This December is the 30th anniversary of World AIDS Day, with the theme: “Know Your Status”.
When did HIV testing start?
The effort to develop effective treatment for HIV is remarkable in its speed and success. Clinical trials of antiretrovirals (ARVs) began in 1985 – the same year that the first HIV test was approved – and the first ARV was approved for use in 1987.
Does HIV cause immune depletion?
This is considered a major challenge as that HIV itself causes immune depletion by actively killing off "helper" CD4 T-cells. Furthermore, the body’s ability to fight HIV with so-called "killer" CD8 T-cells gradually wanes over time as the body undergoes what is known as immune exhaustion.
Do BNAbs kill HIV?
Most are non-broadly neutralizing antibodies, meaning that they only kill one or several pathogen types. Some recently discovered bNAbs have the ability to kill a broad spectrum of HIV variants—up to 95% in some cases—thereby limiting the virus' ability to infect and spread.
What type of cells are involved in HIV?
Traditionally, specialized white blood cells called CD4 T-cells initiate the response by signaling killer cells to the site of the infection. Ironically, these are the very cells that HIV targets for infection.
Who is James Myhre?
James Myhre is an American journalist and HIV educator. Latesha Elopre, MD, is a board-certified internist specializing in HIV and an assistant professor of infectious diseases at the University of Alabama at Birmingham.
How many people have died from AIDS?
Since the epidemic emerged, 25 million people have died from AIDS and 60 million have been infected with HIV, according to the Joint United Nations Programme on HIV/AIDS.
When was the AIDS virus isolated?
In 1985 , the virus itself was isolated. Following this discovery, Margaret Heckler, the US Human Services Secretary at that time, famously declared, "We hope to have a vaccine [against AIDS] ready for testing in about two years.". Vaccines have worked well against once widespread diseases like smallpox and polio.
When was AIDS first detected?
AIDS was detected in California and New York in 1981, first among gay men and drug users, then in hemophiliacs who had received blood transfusions, and later in non-drug-using men, women, and children. Initially, little was known about how AIDS was transmitted, and even less was known about the virus that caused it.
Can HIV be treated with ART?
Millions of people who have HIV can’t afford ART, so other treatments are needed. This idea of an HIV cure is also called a functional cure. Treatment-free remission means that you’d: Live a healthy life that’s of normal length. Not have to take ART or any other HIV-related drugs to keep the virus under control.
What is the cure for HIV?
There are two different visions of a potential HIV cure: treatment-free remission and viral eradication. Treatment-free remission means the virus is controlled without the need for ART drugs, which a person has to take every day for life. Millions of people who have HIV can’t afford ART, so other treatments are needed.
Who was the Berlin patient?
The Berlin Patient: In 2008, a man with HIV named Timothy Ray Brown was effectively cured while living in Germany. Researchers treated his blood with a stem cell transplant for leukemia, but the treatment also cured his HIV. His stem cell donor carried a mutation of an HIV-related gene called CCR5.
What is the mutation in CCR5?
His stem cell donor carried a mutation of an HIV-related gene called CCR5. This mutation makes a person almost completely resistant to infection. Brown was the only person to be cured of HIV until 2019, when two others were effectively cured with a similar stem cell therapy.
Is there a cure for HIV?
Since there’s no cure for HIV, treating the virus is a life-long process. Translation: You have to take medication every day, forever. Not only that, but you also have to schedule appointments with your doctors and refill your prescriptions, too.
Is antiretroviral therapy good for HIV?
Ho. “There’s still some shame and a fear of stigma associated with the disease.”. That said, antiretroviral therapy is the best way to treat the HIV virus—and you have to stick with it.
Can meds cause dizziness?
In the short-term, the meds may cause nausea, diarrhea, headaches, dizziness, fatigue, and more. Long-term side effects include insulin resistance and a loss of bone density. But Dr. Ho says that some of the short-term effects can fade with time; doctors can also prescribe other meds for the queasiness.
Do people with severe depression have to be on antiretroviral therapy?
Research has shown that people with severe depression are less likely to adhere to their antiretroviral therapy. Others may simply not want to be reminded of their HIV-positive status every day, says Dr. Ho. “There’s still some shame and a fear of stigma associated with the disease.”
Can meds cause nausea?
In the short-term, the meds may cause nausea, diarrhea, headaches, dizziness, fatigue, and more. Long-term side effects include insulin resistance and a loss of bone density. But Dr. Ho says that some of the short-term effects can fade with time; doctors can also prescribe other meds for the queasiness.
Causes
Virologic Failure
- Virologic failure is defined as the inability to maintain a viral load of fewer than 200 copies per milliliter (mL) despite adherence to antiretroviral therapy.1 When antiretroviral therapy is working, the viral load should be fully undetectable, meaning that it is below the level of detection (under 20 to 75 copies/mL, depending on the test).1 If failure is allowed to continue, the viral l…
Immunologic Failure
- Immunologic failure occurs when defensive immune cells, called CD4 T-cells, fail to recover despite fully suppressive antiretroviral therapy. These are the cells that HIV preferentially attacks, and their depletion is a reliable marker for your immune status. The immune status of people with HIV is measured by a blood test called the CD4 count. "No...
Changing Therapy
- If virologic failure is declared, your healthcare provider will order one or more tests to evaluate your "viral pool." When you have HIV, you do not have just one virus but rather a multitude of variants, some of which are drug-resistant. Under the pressure of antiretroviral therapy, the viral pool can change with drug-resistant variants becoming more and more predominant. In some c…
A Word from Verywell
- Treatment failure can also occur in people who are fully adherent, typically after many years of treatment. This is particularly true for those who take some of the older antiretroviral drugs, some of which are more durable (longer-lasting) than others. However, if treatment failure occurs within a relatively short period of time, poor adherence almost invariably plays a part. If this is the case…
