These numbers are challenging to calculate and should therefore be considered rough estimates do not represent the risk of transmission from all exposures to HIV represent the average risk of transmission in the absence of biological factors that can increase risk such as STIs and a high viral load are most relevant to people in stable monogamous serodiscordant relationships These numbers may seem low but HIV transmission can occur after a single exposure the risk may be much higher if certain biological risk factors, such as STIs or a high viral load, are present as more exposures to HIV occur, the overall risk of transmission increases most HIV transmissions in Canada occur through unprotected anal and vaginal sex There are several ways of reducing the risk of HIV transmission from an exposure, such as post-exposure prophylaxis PEP , using antiretroviral treatment to reduce viral load , circumcision, treatment for STIs and vaginal conditions, or engaging in lower-risk activities.

These are estimates of average risk in the absence of biological factors that increase risk. Of course, these numbers will vary based on correct and consistent use of the prevention strategy. Also, there are often research gaps, he says, meaning that in many cases, scientists might not yet have real-world examples to back up these numbers and calculations, but they do have mathematical modeling and the biological rationale for why certain ideas about HIV risk are true.
