Treatment as Prevention

About Treatment as Prevention (TasP)

Treatment as Prevention (TasP) refers to the use of anti-retrovirial HIV medication to reduce the chance of transmitting HIV to others through sex, needle sharing, or during pregnancy and birth.

In short, TasP works by decreasing the amount of HIV in the body. This makes a person’s blood, vaginal fluid, breast milk, and semen less likely to pass HIV to others.

When people living with HIV reduce the amount of virus in the body to “undetectable” levels, by taking ARV treatments, the chance of transmitting HIV to others through sex is reduced to zero – even without the use condoms or PrEP.

Researchers, scientists, and international health organisations are all in agreement that sexual HIV transmission cannot occur when people with HIV are on treatment and our viral load is undetectable.

So, rest-assured, treatment as prevention (TasP) really does work. Combine this with the unequivocal findings that timely treatment is best for our long term health, and it’s a no brainer. Today, coupled with much safer treatment options, we have a clear sense that immediate and constant treatment is best for both for our own health and for the safety of our partners.

How Is HIV Transmitted

HIV can be shared in some body fluids, like blood and semen, but not in fluids like saliva or sweat.


A tablet that you can take to reliably prevent HIV. Lots of people, especially gay and bisexual men, take PrEP to prevent HIV.


A medication, if started within 72 hours, may prevent HIV after a potential exposure to the virus through sex (or injecting).

HIV Prevention

As well as condom use, over the last decade, HIV treatment has come a long way and now plays a vital role in prevention.
