In the season of high incidence of respiratory infectious diseases, in addition to personal protection, daily disinfection of home protection can also effectively reduce the risk of infection. On December 4, the reporter contacted and interviewed relevant experts from the Municipal Center for Disease Control and Prevention to popularize science on the recent indoor air disinfection and disinfection methods of high-frequency appliances in daily contact.
First of all, pay attention to personal hygiene.
Respiratory viruses are mainly transmitted by airborne droplets, and secondly, direct or indirect contact transmission can also occur through contact with items contaminated with patient secretions. Therefore, the first step in preventive disinfection at home is to pay attention to maintaining personal hand, nose and mouth hygiene. Li Wenhao, an expert from the Disinfection and Infection Control Department of the Municipal Center for Disease Control and Prevention, said that washing hands frequently is one of the simplest and most effective ways to prevent infectious diseases. It is recommended that the general public wash their hands frequently in the near future, do a good job of hand hygiene, and wash their hands with soap or hand sanitizer under running water in accordance with the seven-step or six-step handwashing method. When using hand sanitizer, take an appropriate amount of hand sanitizer in the palm of your hand, rub your hands together so that it is evenly applied to each part of your hand, and rub and disinfect until dry.
To reduce the risk of infection, cover your mouth and nose with a tissue when coughing and sneezing. Used tissues and other garbage should be sealed and stored in garbage bags and disposed of in a timely manner to avoid other people's contact. If mouth and nose secretions contaminate the surface, it should be cleaned and decontaminated with adsorbable materials, then disinfected and hand hygiene should be performed. Cleaning items used should also be disposed of promptly.
Indoor air disinfection Ventilation is most effective when windows are opened.
The home environment should follow the principle of "cleaning first, disinfection secondary". For indoor air disinfection, fenestration is the most cost-effective method. It is recommended that the general public insist on opening windows for ventilation every day to maintain indoor air circulation. Ventilation 2 3 times a day according to specific weather conditions, each time not less than 30 minutes. Keep warm when opening windows. When the ventilation conditions are poor, mechanical ventilation or circulating air disinfection machine can be used for air disinfection. Chemical disinfection of the air should not be carried out when there are people in the room.
Floor disinfection eliminates the need to sprinkle disinfectant in every corner of the home. The concentration of 500 milligrams of chlorine-containing disinfectant can be prepared, and the specific preparation method is that the effective chlorine content is 5%, and 1 part of the disinfectant solution is taken and 99 parts of water are added. Wipe with a rag or mop and wipe with the above disinfectant solution. The disinfection time is 5 minutes, and then wipe it clean with water, and the personnel can only enter after ventilation.
For utensils with a high frequency of daily contact, disinfection work should be done in a classified manner. Li Wenhao said that for the daily disinfection of cups and tableware, it is recommended to first remove food residues, sterilize them by boiling or circulating steam for 15 minutes, or use 250 milligrams of effective chlorine to disinfect with chlorine, the preparation method is 5% effective chlorine content, take 1 part of disinfectant when preparing, add 199 parts of water to soak, and then wash with water after 15 minutes.
For frequently touched environmental surfaces such as doorknobs, faucets, toys, etc., cleaning can be wiped and disinfected with 500 milliliters of chlorine-containing disinfectant or other disinfectants that can be used for surface disinfection, and then wiped clean with water;Small items such as mice and keyboards can be wiped and disinfected with 75% alcohol wipesTowels and other fabrics are mainly disinfected, and can also be soaked in 250 milliliters of chlorine-containing disinfectant or other disinfectants that can be used for fabric disinfection. To do this, prepare a chlorine-containing disinfectant solution at a concentration of 250 milligrams, completely soak the fabric in the disinfectant solution for 15 minutes, and then wash it according to the usual steps. The method of circulating steam or boiling sterilization for 15 minutes is equally effective for disinfecting fabrics such as towels.
Scientific moderation Over-disinfection is not advisable.
Home disinfection should be scientific and moderate, and excessive disinfection is also poisonous. Experts from the Center for Disease Control and Prevention remind that in order to avoid excessive disinfection, disinfection products must be used in accordance with the instructions. Because disinfectants are irritating, everyone is reminded to pay attention to personal protection when preparing and using, wearing masks, gloves, etc. Chlorine-containing disinfectants have certain corrosiveness and bleaching, so pay attention to wipe with water to remove the residue after disinfection to prevent damage to the disinfected items.
