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.
Is there a cure for HIV/AIDS?
The answer isn’t a simple yes or no. Here’s what you need to know about the “cure” to HIV/AIDS: Let’s be clear on what the latest cases of reported “cures” mean. Scientists are careful to describe the current “cure” as a case of “long term viral remission,” meaning that the HIV virus is suppressed, but still present in the body.
Is HIV cured?
Scientists are careful to describe the current “cure” as a case of “long term viral remission,” meaning that the HIV virus is suppressed, but still present in the body. The patients currently reported as “cured” are off antiretroviral treatment (ARVs) and not experiencing any symptoms. Photo Credit: USC Annenberg Center for Health Journalism.
Who was the first person to cure HIV?
Talk of the first known, sustained cure started with Timothy Brown, known as the “Berlin Patient.”. Brown was diagnosed with HIV in 1995 and in 2007, his HIV went into remission after undergoing a bone marrow stem cell transplant. Prior to his transplant, Brown had been diagnosed with leukemia.
Who is the London Patient?
Over the next decade, similar attempts to replicate Brown’s results failed—that was until Adam Castillejo, known only as the “London Patient” in 2019. Castillejo was diagnosed with HIV in 2003, and then with advanced Hodgkin’s lymphoma in 2012.
How did CRISPR eliminate HIV?
Using a super form of antiretroviral therapy, called LASER, and a gene-editing technology known as CRISPR, these scientists were able to eliminate HIV from the DNA of 9 mice. After treating the mice with LASER, researchers used CRISPR to erase any remaining HIV DNA from their bodies.
Can CRISPR remove HIV from animals?
After treating the mice with LASER, researchers used CRISPR to erase any remaining HIV DNA from their bodies. These results are the first to prove that removing HIV in living animals is in fact possible. Next up, researchers are looking to replicate this success in primates. THE SÃO PAULO PATIENT.
Is there a third person who has been cured of HIV?
THE SÃO PAULO PATIENT. Almost exactly a year later, in July 2020, researchers from Brazil announced a third person who had been reportedly cured of HIV--but for the first time, without the risks of a stem cell transplant.
Does HIV evade the immune system?
It evades the immune system, so the body’s natural ability to fight or clear it is limited. Although there are no precedents that might guide us to a vaccine or cure, we have learned a lot about how HIV works – and about its weaknesses – in the past five years.
How does HIV mutate?
It mutates rapidly in the body, as well as across geographic locations, establishing latent reservoirs within cells that enable it to emerge and replicate months or even years later. It evades the immune system, so the body’s natural ability to fight or clear it is limited.
Is an ounce of prevention worth a pound?
An ounce of prevention, Benjamin Franklin famously said, is worth a pound of cure. But that is not always true when it comes to research into infectious diseases. Though scientists have traditionally tended to focus on either prevention or cure, defeating the HIV/Aids virus will require researchers – and their funders – to collaborate ...
Is HIV a death sentence?
Because HIV/Aids is already the world’s most studied infectious disease, an HIV diagnosis is no longer a death sentence. Yet we are still far from defeating the virus. Infection rates continue to rise in specific regions and populations, and more than half of the people living with HIV worldwide do not even know they have it.
How many people with HIV do not know they have it?
Infection rates continue to rise in specific regions and populations, and more than half of the people living with HIV worldwide do not even know they have it. Three out of five HIV-positive people still are not receiving antiretroviral therapy.

Why is it important to take HIV medication?
Why taking your HIV treatment properly is important. To allow HIV treatment to work properly, it’s important that you take your HIV medication as prescribed. This is often called ‘adherence’, and it means taking the drugs at the right times, at the right dose, and following any advice about food restrictions.
Can HIV be resistant to drugs?
Your HIV may also become resistant to drugs similar to those you are currently taking (that is, in the same ‘class’ of drugs). This is called cross-resistance and the risk varies between different classes of HIV drugs.
What is adherence in HIV treatment?
To allow HIV treatment to work properly, it’s important that you take your HIV medication as prescribed. This is often called ‘adherence’, and it means taking the drugs at the right times, at the right dose, and following any advice about food restrictions.
Can HIV be replicated?
The levels of the drugs in your blood are not high enough to effectively fight against HIV. If this happens, your HIV will be able to replicate. Your viral load will increase and your CD4 cell count (an important indicator of the health of your immune system) will fall.
Can HIV be passed on to a sexual partner?
Your viral load will increase to a level at which you may pass HIV on to a sexual partner (if condoms or pre-exposure prophylaxis – PrEP – are not being used). You would then need to change your HIV treatment.
What is adherence to HIV?
This is often called ‘adherence’, and it means taking the drugs at the right times, at the right dose, and following any advice about food restrictions.

But some small number remain, and over time, those HIV cells replicate, and replicate, and replicate. Then, usually 10 years after the initial infection, the viral load reaches a critical count, ...
How does HIV spread?
HIV spreads by hijacking a subset of white blood cells called T cells, which are the body's first line of defense against foreign invaders, and using the cells' DNA to make copies of itself or replicate; in this process, these T cells get destroyed.
