HIV Basics

What Is HIV & AIDS?

HIV stands for Human Immunodeficiency Virus. The virus affects the body’s immune system, its main defence against disease. If untreated, HIV weakens a person’s immune system over time, leaving them open to other life-threatening infections.

AIDS stands for Acquired Immune Deficiency Syndrome which refers to the range of specific illnesses that a person with HIV may get when their immune system becomes weakened by HIV.

It is important to test for HIV often so that anyone who may unknowingly have HIV can start on effective treatments to stay healthy. It is recommended that anyone diagnosed with HIV goes on treatment immediately as this will reduce the level of HIV in the body, maintain a strong immune system and keep the person healthy. For those adhering to HIV treatments, this prevents the progression of HIV to AIDS.

How Is HIV Transmitted?

HIV is transmitted when bodily fluids carrying HIV (blood, semen, vaginal fluids, breast milk or anal mucus) pass from a person with HIV into the bloodstream of a person who does not have HIV.

HIV can be transmitted in several ways, but for gay, bi and other men who have sex with men, most infections occur during anal sex without the protection of condoms, PrEP or an undetectable viral load (UVL). Other forms of transmission include vaginal/front hole sex without condoms and sharing injecting equipment.

For people who do not have HIV, they can prevent acquiring HIV by being responsible for their health using condoms, PrEP or PEP. HIV positive people on treatment with a UVL will not transmit HIV to their partners.

How Does HIV Affect Health?

When left untreated, HIV causes damage to the immune system over time although the precise impact can vary from person to person. Among other things, a damaged immune system can impact on a person’s ability to fight off infections and illnesses. When someone contracts HIV they may experience something called a ‘seroconversion illness’ which is associated with flu like symptoms. Not everyone will get this illness.

Adhering to HIV treatment will reduce the risk of developing adverse health conditions associated with HIV. The Start Study found that commencing treatment immediately after infection makes a significant difference to a person’s health outcomes. Many people with HIV consider the condition a manageable illness. With appropriate care, treatment and support, the impact of HIV on a person’s health and life expectancy can be greatly reduced.

HIV Prevention Basics

There are a range of ways to prevent HIV. Sometimes the use of various strategies to prevent HIV is referred to as ‘combination prevention’. Combination prevention includes the use of condoms, PrEP, PEP,  having an Undetectable Viral Load (UVL) or Treatment as Prevention (TasP) otherswise known as Undetectable = Untransmittable (U=U).

Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP) is the use of HIV medication to keep HIV negative people from contracting HIV.

When PrEP was first introduced, taking it daily was the recommendation for everyone. Since then, research supports the safety of taking PrEP in other ways that are just as effective as daily dosing.

Today, PrEP can be taken daily, on-demand or periodically.

Read more about the different ways to take PrEP on our Ending HIV website.

PrEP is highly effective at preventing HIV but PrEP does not prevent the transmission of other sexually transmitted infections (STIs). For this reason, it is recommended that people who are taking PrEP to test for STIs every three months.

People who are using PrEP should consider maintaining their condom use, particularly for casual partners.

PrEP is now available on the PBS, making it affordable and accessible across Australia.

Find out more about how to access PrEP on our Ending HIV website.

Condoms & Lube

Condoms prevent or reduce the exchange of semen, vaginal fluid, or blood between partners during sex. When used with lube, condoms are a highly effective way to ‘stay safe’ and prevent HIV transmission.

Condoms also offer protection against a range of other sexually transmissible infections (STIs). They do this by preventing the transfer of bodily fluids or by covering affected genital areas.

Find out more about using condoms and staying safe on our Ending HIV website.

Undetectable Viral Load (UVL) & U = U

When a person living with HIV is on effective treatment, they often achieve what is called an undetectable viral load (UVL). This means that HIV is no longer able to be detected in their body by viral load tests, meaning the amount of virus is extremely low. Many people refer to this as being “undetectable”.

U=U, which stands for ‘undetectable equals untransmittable’, emphasizes the science behind undetectable, declaring it a safe and effective way of preventing transmission. On dating apps, some guys have started to use the term in their profiles to help communicate their undetectable status.

There has never been a case of a person with an undetectable viral load passing on HIV to a sexual partner, a fact backed up by major international studies. For this reason, using treatment to prevent HIV (TasP) is considered effective and safe.

HIV Prevention Basics

There are a range of ways to prevent acquiring HIV, referred to as combination prevention. This includes the use of condoms, PrEP and/or choosing partners with an undetectable viral load (UVL).

Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP) is the use of HIV medication to keep HIV negative people from contracting HIV. In Australia, taking pills orally is most commonly available option for PrEP. Depending on how one identifies and how frequently they have sex, there are different options for how to take PrEP including:

• Daily: suitable for everyone and involves just one pill a day ongoing
• On-demand: suitable for cis men who have sex with men only, and involves taking pills at specific times around sex

PrEP is highly effective at preventing HIV when taken as prescribed. Although PrEP does not prevent the transmission of other STIs, which can, in turn, increase the possibility of HIV infection. This is why we encourage people who are taking PrEP to regularly check in with their sexual health provider.  If any STIs do occur, get them treated and follow the advice of your sexual health provider.

People who are using PrEP should consider maintaining their condom use, particularly for casual partners, until you are aware of their testing regimen.

PrEP is now available on the PBS, making it affordable and accessible across Australia. Find out more information on how you can access PrEP now here.

Many people refer to this as being “undetectable”.

In terms of HIV prevention, there has never been a case of a person with an undetectable viral load passing on HIV to a sexual partner, a fact backed up by major international studies.

“U=U” (Undetectable = Untransmittable) is a term that acknowledges the benefits of taking treatment to achieve an undetectable viral load, specifically regarding preventing the onwards transmission of HIV.

Other Risk Reduction Strategies

There are a range of other strategies that can reduce, but don’t eliminate, the risk of HIV transmission.

These strategies include: ensuring HIV-negative partners are insertive (i.e. the ‘top’); ensuring partners have the same HIV status (i.e. pos-pos or neg-neg); and  the insertive partner “pulling out” before ejaculation. All these strategies carry risks that vary according to practice and circumstance.

Our Ending HIV Initiative

Help Us End HIV Transmission In NSW

Our Ending HIV initiative aims to educate, inform and support gay, bi and other men who have sex with men – the population group in NSW most at risk from HIV – about the real possibility that HIV transmission in NSW could be virtually eliminated  as a result of advances in testing technologies, prevention strategies and HIV treatments.

The campaign seeks to educate about three key activities they need to undertake to help end the epidemic:

1) Test Often – sexually active gay, bi and other men who have sex with men need to get tested for HIV every 3 months, as this is the only way that undiagnosed infections can be decreased and access to treatment can be increased

2) Treat Early – advances in HIV medicines offer improved health benefits for people with HIV and can reduce traces of the virus in their body to an undetectable level, eliminating the risk of them transmitting HIV

3) Stay Safe – condoms, PrEP, PEP and other risk reduction strategies offer a range of options for preventing the transmission of HIV  and remain central to maintaining a culture of safe sex

Launched in 2013, the campaign forms a key part of the NSW HIV Strategy, a plan committed to achieving the virtual elimination of HIV transmission in NSW.

Test Often

Knowing your HIV status is vital to our efforts to end HIV transmission in NSW.

For gay, bi and other men who have sex with men, it’s recommended to get tested for HIV and STIs every three months while sexually active. People who are not sexually active or in a monogamous relationship may test less frequently but at least annually.

Benefits of Testing

Many new HIV transmissions in NSW occur when someone thinks they’re negative when they are actually positive. That’s because it can take years before HIV symptoms are noticeable.

Testing regularly so you know your HIV status allows you to protect your health and the health of your sexual partners.

If you find out you have HIV, you can start on HIV treatment to protect your health. There are plenty of services available to assist you with a new HIV diagnosis, including many provided by ACON.

Getting Tested

Now that rapid HIV testing is available in NSW, testing for HIV is easier than ever, with results available in around 30 minutes.

You can get tested for HIV at any of ACON’s services, at a sexual health clinic or GP.

There are other testing technologies that are approved for use in Australia, such as

a[TEST]

ACON testing services include a[TEST] Surry Hills, a[TEST] Oxford St, a[TEST] Newtown and a[TEST] Chinese Clinic. Bookings are essential.

Treat Early

By getting on treatment, people living with HIV can improve their health and help prevent HIV transmission.

Benefits of Treatment

For people living with HIV, treatment keeps the immune system healthy and reduces the risk of developing health conditions associated with HIV.

Research shows that when a person living with HIV is on effective treatment and has had a sustained undetectable viral load (UVL) for six months, it is not possible for them to transmit the virus to a sexual partner.

Who’s On Treatment?

Over 95% of people living with diagnosed HIV in NSW are on treatment. We need to maintain this number if we’re going to reach our goal of ending HIV transmission.

Why Early Treatment?

You may not know you’ve contracted HIV, but in the early stages of a new HIV infection the amount of HIV virus in your body (viral load) is very high. Having a high viral load greatly increases the risk of HIV transmission. This is why HIV is more likely to be transmitted by people who don’t know they’ve got HIV and during the early stages of their infection.

It’s important to test regularly and, in the case of a positive result, get onto treatment early. If you know your HIV status, you can make informed choices about your health, including HIV treatment and sexual health.

HIV Self Testing

HIV self-testing (HST) devices allow for discretion in the HIV testing process for those who may feel more comfortable testing in this way or who may not be able to physically attend a testing service.

While there is an option to buy HST devices from overseas, we encourage people to purchase TGA-approved HST devices, as quality assurance is provided as well as local contact information for support and follow-up.

As these devices are screening tests, the possible results are ‘reactive’, ‘negative’ (non-reactive), or ‘invalid’. Any reactive result needs to be confirmed by a diagnostic test conducted by a healthcare professional.

HIV self-tests work by detecting HIV antibodies, which the immune system produces anywhere between 2 weeks to 3 months after exposure to the virus. Because of this window period, HIV self-test devices may not provide a conclusive result until up to 3 months after a risk of exposure.

If you are considering self-testing for HIV, it’s important to make sure you know who to contact so you can be linked into care, support and diagnostic testing services. For this reason, we also suggest that people not test alone and test at times when relevant support services are operating.
