What Is The Difference Between PrEP and TAsP?

Hey, guys. It’s Dr. George here. Today I’ve been asked the question: What is the difference between treatment as prevention and PrEP? These are two important concepts when it comes to HIV, but also HIV prevention. It is important that people are aware of the differences between the two.

PrEP is pre-exposure prophylaxis, a single tablet taken every day that reduces the risk of HIV infection in a person who is HIV negative, somebody who is not living with HIV. What it does is it blocks HIV from being able to take hold in the body.

It is very different to treatment as prevention, or TasP. What TasP is is when a person is living with HIV. Successful treatment over HIV is the use of medications to bring the replication of the HIV virus in the body down to a point where it can no longer be detected in the blood. That’s called a non-detectable viral load. And, as we know, a person with a non-detectable viral load is not able to transmit HIV full stop. Treatment as prevention is allowing people to get onto HIV treatment that greatly improves their own health benefits but also the health benefits of their partners by blocking the transmission of HIV as well.

You may have seen a previous video that I did which was about U=U, or undetectable viral load is untransmittable. That’s what TasP is about. I hope this is helpful and helps clarify the difference between PrEP, or a tablet taken every day to block HIV from being able to take hold in the body of somebody who’s negative, versus TasP, or treatment as prevention, which is a medical intervention for people living with HIV that stops the replication of HIV to a point where it can not be detected in the blood. What this means is great health benefits for the person living with HIV and their sexual partners because HIV cannot be transmitted.

That’s the difference between TasP and PrEP. I hope that was helpful. If you have any questions, please by all means send me a message and I’ll make sure I get an answer for you. Have a great day, guys
