[Future direction of medical care system for patients with infectious disease and the new infectious diseases control law in Japan--centering around a category 1 hospital].

As of April 1, 1999, the new Infectious Diseases Control Law became effective in Japan. Under the new law, there are three types of category for medical care systems such as "Specified Infectious Disease Medical Hospital", "Category 1 Infectious Disease (Ebola virus hemorrhagic fever, Marburg disease, Lassa fever, Crimean-Congo hemorrhagic fever and plague) Designated Hospital" and "Category 2 Infectious Disease (Cholera, Sigellosis, Typhoid fever, Paratyphoid fever, Poliomyelitis and Diphtheria) Designated Hospital". In these categories, "Category 1 Infectious Disease Designated Hospital" should be designated by prefectural governments, one hospital per prefecture. Recently some papers indicated that (1) whether each government should arrange a category 1 hospital, (2) whether strict isolation with precautions against airborne spread including negative air pressure with anterior-room should be required, (3) plague is not a dangerous disease and the patient with plague is not required of Category 1 hospital but Category 2 hospital for medical care and infection control. The purpose of this article is, including a counterargument for these opinion, to summarize the point of view for the new medical care system under the new law and to search for the future medical care system in Japan. First of all, medical care for patients with infectious diseases should not be a special one but the extension of the general one. Second, we understand that one of the purposes for Category 1 hospital is the core hospital concerning the therapy, pre/post education and research for infectious diseases in each prefectures. Third, the constructive standard for Category 1 hospital should be a strict one including negative air pressure rooms with an anterior-room and an outside hall, and the air should not be recirculated. Under the big chance of enforcement of this new Infectious Diseases Control Law in Japan, we should try to restruct about medical care system for patients with infectious diseases in a long-range plan.
