[New preventive possibilities in HIV infection].

The most important preventive measures against accidental HIV infection in health care are the education of personnel and the observance of routine procedures in everyday work. In this way, the accidental infection rate can be reduced by more than 50 per cent. Consistent registration of the causes of accidental infection can further reduce work-related risks. In January, the Danish authorities issued guidelines for the use of antiviral chemoprophylaxis against HIV infection following occupational exposure. A four-week course of triple-drug anti-retroviral prophylaxis is recommended to prevent HIV infection in causes of needle-stick or other penetration injuries.
