Killing of infectious agents outside the body by chemical or physical means directly applied. 1. Concurrent disinfection is the application of disinfective measures as soon as possible after the discharge of infectious material from the body of an infected person, or after the soiling of articles with such infectious discharges. All personal contact with such discharges or articles being prevented prior to such disinfection. 2. Terminal disinfection is application of disinfective measures after the patient has been removed by death or to a hospital, or has ceased to be a source of infection, or after isolation practices have been discontinued. Terminal disinfection is rarely practised; terminal cleaning generally suffices along with airing and sunning of rooms, furniture and bedding. It is necessary only for diseases spread by indirect contact; steam sterilisation of bedding was considered desirable after smallpox (now eradicated).
