Therefore, Dr. Zhu Jiming said that from an epidemiological point of view, in order to reduce the occurrence of nosocomial infections, epidemic prevention hotels, and cluster events in large institutions, it is recommended that in addition to chemical disinfection methods such as alcohol and bleach wiping, physical disinfection methods can also be added. It is better to use it interactively. Common company banner design physical disinfection methods include opening windows for ventilation, boiling, high-temperature steam, dry-heat sterilization, and far-infrared and UV light disinfection. Among them, UV light and far-infrared disinfection use ultraviolet and far-infrared lamps to penetrate the cell membrane and cell wall of the bacteria through light, destroy the genetic material of the bacteria, and make it inactive, thereby weakening the spread and reproduction of the bacteria. Among them, the low intensity of far-infrared rays requires long-term irradiation to achieve the sterilization effect. Ultraviolet light destroys the DNA structure of bacteria or viruses through UVC ultraviolet light, which can quickly disinfect and sterilize the entire space and the air in the space. Recent studies have confirmed that under the condition of UVC energy of 3.7-16.9 mJ/cm 2 , the COVID-19 virus can be completely inactivated by irradiation for a few seconds, making it inactive, and UVC can also significantly reduce Candida albicans and Escherichia coli. , Pseudomonas aeruginosa, Staphylococcus aureus and other bacterial counts, especially to help reduce the harm of drug-resistant strains. Therefore, medical institutions often use ultraviolet disinfection lamps to disinfect and clean the space. However, Dr. Zhu Jiming also reminded that when using ultraviolet disinfection, personnel need to leave the scene to avoid eye or skin burns by light waves.
