Risk Calculator
Depending on the type of sex you’re having, the level of risk of HIV transmission can vary.
Use this calculator to find out the risk associated to scenarios based on anal sex and where condoms are not being used.
Oral sex is considered to be very low risk for HIV, and condoms, when used properly with lube, are a highly effective way to prevent HIV and other STIs.
Remember, what is low risk for HIV is not necessarily low risk for STIs such as syphilis, chlamydia, gonorrhoea and LGV.
