Can Undetectable Hiv Be Transmitted Through Blood

British Hiv Association Advice

Lets Stop HIV Together Undetectable PSA

The ‘Undetectable equals Untransmittable’ campaign is supported by the British HIV Association , which is the professional association for doctors and other healthcare professionals working in HIV in the UK.

BHIVA says consistent use of HIV treatment to maintain an undetectable viral load is a highly effective way to prevent the sexual transmission of HIV.

BHIVA says healthcare professionals should share this information with all people living with HIV. It advises healthcare professionals to explain the scientific evidence behind U=U, emphasising the importance of excellent adherence to HIV treatment and highlighting that U=U is dependent on maintaining a sustained undetectable viral load.

What Is Viral Suppression

Antiretroviral therapy keeps HIV from making copies of itself. When a person living with HIV begins an antiretroviral treatment regimen, their viral load drops. For almost everyone who starts taking their HIV medication daily as prescribed, viral load will drop to an undetectable level in six months or less. Continuing to take HIV medications as directed is imperative to stay undetectable.

The research on HIV transmission risk in couples trying to conceive when the HIV-positive partner is durably virally suppressed is still limited. If you are HIV negative and are trying to get pregnant with an HIV-positive partner’s sperm, it is generally recommended that you be on PrEP, regardless of your partner’s viral load. This is, however, a clinical judgment and a decision you and your doctor should make considering what is best for you, your partner, and your future child.

Hiv Treatment And Prevention

Simple, effective treatments for HIV are widely available in Australia. In addition to protecting the health and wellbeing of people living with HIV, these treatments significantly reduce the risk of HIV transmission. Almost all people on HIV treatments have very low levels of virus in their body. This is called having an undetectable viral load. There is no risk of HIV transmission from a person with an undetectable viral load. This is sometimes referred to as undetectable equals untransmissible, or U=U.

For people who do not have HIV, but may be at higher risk of it, affordable medication is available that is more than 99 per cent effective at preventing HIV. Known as PrEP , this medication is available through the Pharmaceutical Benefits Scheme from your regular GP.

What Does Undetectable Mean

Ending the HIV Epidemic

The word “undetectable” is the lowest limit of the laboratory tests used to measure HIV viral load. Some viral load tests are very sensitive and can find or detect HIV in a sample of blood when there are only 20 copies of the virus per milliliter . Other viral load tests need up to 200 copies per mL of blood to detect any HIV. In the context of U=U, it does not matter which type of test your doctor uses to measure your viral load. As long as your viral load remains below 200 copies/mL, your risk of sexually transmitting HIV is negligible.

What Does It Mean To Be Durably Undetectable

Taking antiretroviral therapy daily as prescribed to suppress HIV levels leads to an undetectable status. A person is considered to have a durably undetectable viral load if their viral load remains undetectable for at least six months after their first undetectable test result. It is essential to continue to take every pill every day as directed to maintain an undetectable viral load.

Talk With Your Hiv Health Care Provider

Talk with your health care provider about the benefits of HIV treatment and which HIV medication is right for you. Discuss how frequently you should get your viral load tested to make sure it remains undetectable.

If your lab results show that the virus is detectable or if you are having trouble taking every dose of your medication, you can still protect your HIV-negative partner by using other methods of preventing sexual transmission of HIV such as condoms, safer sex practices, and/or pre-exposure prophylaxis for an HIV-negative partner until your viral load is undetectable again.

Taking HIV medicine to maintain an undetectable viral load does not protect you or your partner from getting other sexually transmitted diseases , so talk to your provider about ways to prevent other STDs.

If I Have A Viral Load Blip Could I Pass On Hiv

People with an undetectable viral load sometimes experience what are called blips in their viral load. Their viral load increases from undetectable to a low but detectable level before becoming undetectable again on the next test.

For example, your viral load may temporarily rise to 60 copies/ml or 150 copies/ml. This should not be a cause for concern.

Remember that in the PARTNER and Opposites Attract studies, undetectable was defined as below 200 copies/ml. These studies showed that transmission does not occur below this level.

However, a blip could indicate a problem if it happens around the same time as missed or late doses of your medication, or if your viral load stays above detectable on two consecutive tests.

What Will Being Undetectable Mean For Me

HIV: Journey to Undetectable

Having an undetectable viral load means that your ART is effectively controlling your HIV. This will protect your immune system and help you to stay in good health.

Being undetectable also means that you dont have to worry about passing HIV onto your sexual partners. For many people this is just as important to them, giving them relief from the anxiety of passing HIV on. Some people find that knowing theyre undetectable makes it easier to with others, as it can be reassuring for others to know that your health is protected and you cant pass it on too.

If Im Undetectable Is There A Chance My Viral Load Will Become Detectable Again

Being undetectable does not mean that you are cured of HIV. There are three instances when your HIV viral load might come back and be detectable again.

The most common instances are so-called viral blips. Blips are when your HIV levels become slightly detectable, but at a very low level, and then goes back to being undetectable again. People may experience viral blips when they take their HIV medications every day. Viral blips are usually due to issues in the lab, such as some slight error in the test or in the test conditions in the lab. Occasionally they are due to a slight but true increase in the viral load due to a stress such as an illness or a vaccine. Viral blips, in which the viral load goes right back down to undetectable soon, are considered harmless. There is no appreciable chance that a person with a viral blip will transmit HIV to another person.

People also become detectable when they stop taking their HIV medications or take them only partially. It may take between a week to several weeks after stopping HIV treatment for HIV to become detectable again, but people will see the levels of virus in their body go up to detectable levels.

What About Sexually Transmitted Infections

It is important to remember that while HIV treatment will protect your partners from your HIV, it does not protect them or you from other sexually transmitted infections . For this reason, regular sexual health check-ups are recommended. Using condoms will help prevent STIs.

Another concern is whether having a STI could lead to an increase in viral load. This does happen to people with HIV who are not taking treatment: for instance, syphilis can double your viral load. HIV-negative partners are also more likely to get HIV if they have an STI.

But it is not the case for people taking HIV treatment who have an undetectable viral load. In the PARTNER and Opposites Attract studies, there was not a single HIV transmission even though many people had STIs.

If you maintain good adherence to HIV treatment, catching an STI will not raise your viral load from undetectable to detectable. Effective treatment prevents sexual transmission of HIV even if there are other STIs present.

Keep Taking Your Hiv Medication To Stay Undetectable

HIV is still in your body when your viral load is suppressed, even when it is undetectable. So, you need to keep taking your HIV medication daily as prescribed. When your viral load stays undetectable, you have effectively no risk of transmitting HIV to an HIV-negative partner through sex. If you stop taking HIV medication, your viral load will quickly go back up.

If you have stopped taking your HIV medication or are having trouble taking all the doses as prescribed, talk to your health care provider as soon as possible. Your provider can help you get back on track and discuss the best strategies to prevent transmitting HIV through sex while you get your viral load undetectable again.

Other Prevention Benefits Of Hiv Treatment

How is HIV transmitted? Facts, risk factors, and prevention

In addition to preventing sexual transmission of HIV there are other benefits of taking HIV medication to achieve and maintain an undetectable viral load:

  • 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 dont know if a woman living with HIV who has her HIV under control can transmit HIV to her baby through breastfeeding. While it isnt 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.
  • 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.

There is effectively no risk of sexual transmission of HIV when the partner living with HIV has achieved an undetectable viral load and then maintained it for at least six months. Most people living with HIV who start taking antiretroviral therapy daily as prescribed achieve an undetectable viral load within one to six months after beginning treatment.

A persons viral load is considered durably undetectable when all viral load test results are undetectable for at least six months after their first undetectable test result. This means that most people will need to be on treatment for 7 to 12 months to have a durably undetectable viral load. It is essential to take every pill every day to maintain durably undetectable status.

What Does It Mean If Someone Is Undetectable

In the context of HIV testing, undetectable refers to when the HIV copies in a persons blood are so low that they do not show up on a lab test. The test measures a persons viral load.. A person living with HIV who is considered untransmittable means that they are virtually incapable of transmitting the HIV virus to someone else.

Bites That Break The Skin

A bite that opens the skin and causes bleeding can lead to the transmission of HIV. However, according to the

goes up with increasing viral load.

Viral load is highest both during the early phase of HIV and without treatment with antiretroviral medications. Taking antiretroviral medications every day can reduce a persons viral load to very low levels that cannot be detected through testing.

In this way, antiretroviral medications are not only a treatment, but an important tool for prevention. When HIV cannot be detected in the blood, a person living with HIV cannot sexually transmit the virus to a partner without HIV.

This principle is called Undetectable = Untransmittable .

It can take up to 6 months of taking antiretroviral medications each day to achieve an undetectable viral load.

A persons viral load is said to be durably undetectable when all test results are undetectable for at least 6 months after the first undetectable result.

There are a couple reasons that STIs can raise HIV risk. First, the symptoms of many STIs include genital inflammation, sores, or ulcers. These can all increase the chance of transmitting the virus from one person to another.

Second, like HIV, transmission of STIs is associated with some of the same types of behaviors, such as engaging in sex without a condom or other barrier method.

Some research has also indicated that certain STIs may be more with HIV transmission than others. These STIs include:

Missing doses of HIV medicines can reduce their usefulness and increase the possibility of developing drug resistance, which makes certain HIV drugs lose their effectiveness. If you realize you have missed a dose, go ahead and take the medication as soon as you can, then take the next dose at your usual scheduled time.

If You Swallow The Semen Of An Hiv

The risk of acquiring HIV during oral sex is pretty low, but it isn’t zero. Taking your partner’s ejaculate in your mouth appears to make transmission more likely. Almost all of the individuals who say that oral sex must have been the way they acquired HIV and whose cases have been medically evaluated mention that they took ejaculate in the mouth.

It isn’t actually the swallowing that matters, it’s probably having the ejaculate in your mouth . In the stomach, digestive enzymes and acidity may inactivate HIV.

But the risk of acquiring HIV during vaginal or anal sex is far, far higher than during oral sex. It’s also worth remembering that when a person with HIV receives antiretroviral treatment, the amount of HIV in his body fluids falls dramatically. Put simply there will be very little HIV in his semen, so transmission is highly unlikely. This applies to all forms of sex, including oral sex.

How Is Pep Different From Prep

PrEP and PEP are both forms of HIV prevention for people who are HIV-negative. A big difference between PrEP and PEP is that PrEP is taken before potential exposure, while PEP is taken after possible exposure to HIV. While PEPis prescribed in emergency situations and should be taken within 36 hours of exposure, PrEP is a daily pill that people can take to protect themselves against HIV if they think they will be sexually exposed.

Can I Get Hiv From Donating Blood

There is no chance of getting HIV from donating blood. New, disposable and sterile needles will be used to collect your blood.

If you suspect that the needle your healthcare professional is using is not new or sterile then ask them to change the needle and check that it comes out of a sealed pack before agreeing to give blood.

How Do We Know Treatment As Prevention Works

Ending the HIV Epidemic

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. This means that if you keep your viral load undetectable, there is effectively no risk of transmitting HIV to someone you have vaginal, anal, or oral sex with. Read about the scientific evidence.

The risk of transmission of HIV or hepatitis B or C from an infected player is:

  • negligible for other athletes and players involved in contact sports
  • negligible for first aid officers who follow infection control guidelines
  • zero for coaches, trainers, officials and spectators.

HIV and hepatitis B and C cannot spread through:

  • sweat or saliva from other sportspeople
  • sharing drink bottles with team members
  • hugging or shaking hands.

Can My Viral Load Continue To Change

Yes, your viral load can continue to change. This would usually be a result of factors to do with your adherence , or other health issues. Regular viral load monitoring will help you stay on top of these changes, so you can manage your health accordingly.

Your viral load usually drops quickly after first starting treatment, however it may be a while before it reaches a point where its undetectable. Most people who adhere properly to their treatment become undetectable after about six months, but its important that you have a viral load test to confirm this.

While changes to viral load can occur, they should be relatively uncommon for people who adhere properly to their medication and are otherwise in good health. Your viral load monitoring appointments are there to help you to identify and respond to any changes in your viral load.

These appointments also give you time to discuss any difficulties you are having with your medication. Often big life changes, like starting a new relationship or moving to a new place, can make adherence more difficult. Your healthcare worker can help you with any new challenges and work with you to stay healthy and keep your viral load low.
