? Norovirus is one of the common pathogens causing acute gastroenteritis. Norovirus is highly contagious and spreads quickly. The transmission routes are diverse, and the whole population is generally susceptible, mainly affecting adults and school-age children, and it is high in cold seasons. Norovirus is an RNA virus, which is very easy to mutate. Every few years, new mutant strains will appear, leading to global or regional epidemics. Norovirus causes 60%-90% of non-bacterial diarrhea in the United States every year.
The incubation period of norovirus is relatively short, generally 12-48 hours. The most common symptoms are diarrhea and vomiting, followed by nausea, abdominal pain, headache, fever and muscle pain. Although norovirus infection is mainly manifested as a self-limited disease, a few cases will still develop into severe illness or even death, usually occurring in the elderly and young children.
How does the school do a good job in environmental disinfection service?
Public places in school institutions (such as classrooms, dormitories, canteens, libraries, bathrooms, etc.). ) Regularly clean and ventilate, and regularly clean and disinfect key parts such as door handles, stair handrails, faucets, toilet buttons, elevator buttons, and handrails on and off the bed. Focus on disinfection of environmental surfaces, daily necessities, food processing tools, drinking water, etc. Dispose of vomit contaminated by vomit and feces according to the standard.
Specific disinfection service measures:
1. Desk for classroom articles: daily hygiene is the main part, and high-frequency contact parts (podium, tables and chairs, window sills, corner cabinets, doors and windows, handles, floors, walls, etc. ) can be sprayed or wiped with 1000mg/L chlorine-containing disinfectant and 3% hydrogen peroxide for disinfection. 15-30 minutes later, wipe with water.
2. Toys and teaching AIDS:? Toys and teaching AIDS, such as paper, that can't be touched with water can be kept clean, dry and exposed to the sun. Ultraviolet radiation can be used to disinfect the surface, and obviously polluted items should be discarded in time. Toys and teaching aids such as plastics, wood and cloth that can be wetted by water can be soaked in 1000mg/L chlorine-containing disinfectant, 3% hydrogen peroxide or 0.35-0.5% peracetic acid for 30 minutes, then washed with clear water for 2-3 times and dried before use.
3. canteen:? The canteen floor and kitchen utensils can be wiped (dragged) with chlorine-containing disinfectant with effective chlorine concentration of 1000 mg/L, and then wiped (dragged) with clean water after 15-30min, at least once a day. Wear a mask at work, gloves when handling raw food, and pay attention to hand hygiene at any time. The canteen work clothes should be cleaned in time. If it is contaminated by dirt, it should be replaced and cleaned in time, and it should be properly protected when touching food.
4. bathroom:? Generally, chlorine-containing disinfectant with effective chlorine concentration of 1000mg/L can be used to wipe door handles, faucets, toilet buttons, hand washing countertops, etc. Or spray disinfectant for disinfection. If there is a small amount of vomit or excrement, it should be covered with disposable absorbent material and chlorine-containing disinfectant with effective chlorine of 5000 mg/L ~ 10000 mg/L, and carefully removed after a period of action. After the pollutants are completely removed, follow-up disinfection should be carried out with reference to the disinfection service method in the summary table.
? The vaporized hydrogen peroxide sterilizer developed by Shanghai Fantong Biological Disinfection Service Company is a common disinfection equipment in the medical field, which can meet the highest sterilization requirements, kill 6 lg spores and effectively kill norovirus. In the process of disinfection and sterilization service, vaporized hydrogen peroxide is reduced to water and oxygen without any harmful residue, which is harmless to the environment and human body. It is very suitable for disinfection in schools and kindergartens.
Fan Tong's space disinfection service technology evaporates hydrogen peroxide. Hydrogen peroxide gas is generated by heating hydrogen peroxide solution and diffused into the air. Hydrogen peroxide molecules will release strongly oxidizing free radicals, killing various microorganisms in the air and on the surface of space objects, including bacteria, fungi, viruses, spores and so on. Some sanitary dead corners that are difficult to wipe, 360-degree disinfection without dead corners. Built-in WIFI and IOT technology, with its own degradation and dehumidification unit, space dehumidification, sterilization and degradation, the whole sterilization process is independently completed by one machine. Simple operation, one-button start, greatly saving manpower. Compared with the traditional manual disinfection operation mode, Fantong intelligent disinfection robot has obvious advantages: better disinfection effect, higher efficiency and more time and labor cost savings. At present, Shanghai Fantong Biological Disinfection Service can provide an overall disinfection service plan for pharmaceutical enterprises, biological laboratories, hospitals, food enterprises, production workshops, schools and kindergartens and other enterprises with disinfection needs.
