|Receptive anal intercourse||1%|
|Insertive anal intercourse||0.04%|
|Receptive vaginal intercource||0.1%|
|Insertive vaginal intercourse||0.05%|
|Receptive fellatio with ejaculation (Oral Sex)||0.04%|

- HIV transmission from splashes of contaminated fluids to mucosal surface (i.e. nostrils, mouth, lips, eyelids, ears, genital area and the anus) or non-intact skin is likely to be low, although it has not been accurately justified
- PEP treatment is not 100% effective, best reports quote that PEP can potentially decrease the possibility of transmission by 81%
