RESUMO
The occupation post exposure prophylaxis for AIDS has been carried out for many years and achieved remarkable result,but local trials of non-occupational exposure prophylaxis encountered many ethical problems and difficulties.In the context of high willingness in the AIDS high-risk population to accept non occupational exposure prophylaxis and increasing demand for drugs,starting from the value concept of life dignity,based on the ethical principles of good without hurt,fairness and justice,it is recommended to strengthen the propaganda of non occupational exposure prophylaxis and improve the availability of prophylaxis drug for non occupational exposure,in order to enable the high-risk groups possibly infected with HIV received timely preventive treatment.
