![]() overall risk is 1 in 1000, which is increased in the presence of cervical ectopy, genital tract trauma, menstruation, genital ulcerative disease (in either partner), infectious syphilis and pregnancy.within 2.5 months of seroconversion risk of transmission is estimated to be 0.0082/coital act increased risk if source patient has recently seroconverted, e.g.if source on antiretroviral therapy with suppressed viral load transmission rate = 0 (if viral load if the recipient has a genitourinary infection, the risk of acquiring HIV is also elevated.if the index partner also has a genitourinary infection, for instance, the risk of transmission is approximately doubled.the presence of sexually transmitted infections in either the source or the recipient.the viral load of the source the susceptibility of the host.risk of transmission of HIV following sexual exposure depends on.if source co-infected with HCV, HCV transmission more likely than HIV transmission.No risk if no blood in mouth of biter, and exposure to saliva only only risk if blood in the mouth of the biter, and significant injury.intact skin exposure to blood - no risk.risk for transmission of HIV via mucous membrane exposure is estimated to be 0.09%.mucous membrane and non-intact skin exposure to blood - the risk is very low.post-exposure prophylaxis (PEP) is thought to reduce seroconversion by up to 81%.overall low risk and requires a risk assessment of the type of injury, location of the discarded needle (for example if discarded in a location where people who inject drugs are known to inject), likely age of the discarded needle and the background prevalence of HIV in the local population.risk is more difficult to estimate and the exact incidence of needlestick injuries and the transmission rate is unknown.risk assessment required of the type of injury and the likely infection status of the source.in healthcare setting source patient unknown or unable to test source.increased risk if large gauge needle, hollow needle, deep injury, visible blood on the device, needle was in patient "s artery/vein, or if the source patient has AIDS (or terminal illness).risk of becoming infected with HIV is thought to be between 0.1% and 0.36%.in healthcare setting source patient (serology) known.occurs following a needlestick injury with a needle contaminated with blood from a source known to have HIV.The risk of HIV transmission depends on the exposure and degree of viraemia of the source.
