Treatment as prevention
This method is based on the principle that the HIV-positive person is taking effective HIV treatment and that no more HIV virus has been detected in their blood for at least six months. This means that there will be much less HIV virus present in other bodily fluids such as sperm, vaginal fluid and bowl secretion. In such a case, HIV can no longer be transmitted during sex.
In the case of “treatment as prevention” it is important for the HIV medication to be taken on a regular basis and for a doctor to check regularly whether treatment is successful. It is also important for your HIV-negative partner to consent to not using a condom during sex in such cases.
This method does not protect against other sexually transmitted diseases.
