In the life, the curtains play a protective role in the indoor environment. The pollution situation is different depending on the living environment. For example, the curtains of the fur processing factory often have dangerous pathogens such as Bacillus anthracis and Brucella. Because the hospital is often in contact with patients, there will be a large number of pathogenic microorganisms (such as Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa) on the curtains. The most common problem in ordinary living rooms is the accumulation of airborne dust. Diffusion, the sebum produced by the skin and the debris of the epidermis will also adhere to the curtains, and in the humid air conditioning environment in summer, it becomes a good medium for microorganisms. If you have not washed the curtains for more than half a year, you can use the nose to smell it, there will be obvious "dust smell" (do not try allergic rhinitis, you can use medical white tape to stick on the curtain, you will see some floating ash, The contaminants that penetrate the fabric fibers are not much more).
The curtain can be used as a medium to spread many kinds of diseases: respiratory infections include SARS, tuberculosis, diphtheria, influenza, whooping cough, etc.; skin diseases include white sputum, sputum, etc.; intestinal infectious diseases include dysentery, typhoid, cholera and so on. More important is iatrogenic pollution. Because there are a large number of pathogenic microorganisms in the hospital environment, it is easy to pollute the curtains, especially some bacteria that have low requirements for the natural environment and have strong resistance. Survive and multiply in the longer term. Therefore, in order to maintain cleanliness and prevent disease, it is necessary to disinfect the curtains regularly. Among them, elderly people, children, respiratory diseases and chronic diseases are more susceptible to infection, so it is necessary to regularly clean and disinfect curtains.
