[Present status of nosocomial infections and biohazard of medical waste].

Nosocomial infections are already major problems and are a growing concern to all medical staff and among the general public. Therefore, an effective infection control program, especially against transmission mode of infection, is essential for the well-being of the patients and the safety of hospital personnel. Various categories of medical waste should be segregated adequately and appropriate management(treatment and disposal) is necessary. Adequate handling techniques can protect personnel from injury(occupational infection), and the biosafety manual should be available to prevent injury.
