Technical Field
The invention relates to the field of medical facilities, in particular to an assembled isolation ward and a method.
Background
Malignant infectious diseases are examined by medical departments since ancient times, and the high infectivity, high transfer rate and high death rate of the malignant infectious diseases bring serious threats to the masses of people. In traditional Chinese medicine, the malignant infectious diseases are also classified independently.
The infectious diseases are diseases which are caused by various pathogens and can be mutually transmitted between people, animals or human beings and animals, and are characterized by pathogen, infectivity and epidemicity, immunity exists after infection, some infectious diseases are seasonal or endemic, part of infectious diseases can be difficult to pass by using the seasonal or endemic, but most of infectious diseases can be controlled only according to the infectivity and epidemicity, and the transmission and the epidemicity are controlled by using the links which are necessary to be provided: the vaccine is used for treating infectious diseases of infectious sources (human beings or animals capable of discharging pathogens), transmission routes (routes for pathogens to infect other people) and susceptible people (people who do not have immunity to the infectious diseases), eliminating the infectious sources, cutting off the transmission routes, protecting the susceptible people, controlling the transmission of the infectious sources and treating infected patients, and developing a targeted vaccine to realize immunity. For example, diseases infected by RNA viruses have high variability in the transmission process, and if the transmission is not controlled in time, the diseases are mutated into specific strains or combined with other RNA viruses to generate novel strains, the original treatment effect is seriously affected, and even the targeted vaccine cannot work.
In the process, the aim of easily achieving cutting off the propagation path is undoubtedly achieved, the method is combined with the protection of susceptible people, the infected patient is sent to an isolation ward to be treated in a centralized mode, specialized protection is carried out on medical care personnel, and the control of the infected patient can be effectively achieved.
