[Antiviral prophylaxis following possible sexual exposure to HIV].

In Israel, as in certain European countries, national health guidelines exist for preventive treatment after possible post-coital exposure to the HIV virus. Scientifically, this treatment is still regarded as experimental, though over the past years there is a mounting level of evidence of its efficacy. The administration of prophylaxis for HIV after unprotected coitus may be justified by the similar risk of HIV transmission for certain sexual and occupational exposures.
