ABSTRACT

Through prospective studies, the average risk of HIV transmission after percutaneous exposure to HIV-infected blood has been estimated to be 0.3%. After mucous membrane

exposure the risk has been calculated to be 0.09%. The risk of seroconversion after nonintact skin exposure is thought to be less than that of mucous membrane exposure. The transmission risk after exposure to body fluids other than blood has not been quantified but is thought to be significantly lower than that after blood exposures.
