Hou Binbin Autonomous Region Epidemic Prevention and Control Expert Group, deputy director and chief physician of the district disease control center

Since the epidemic, positive patients have appeared in some communities, causing other residents to be afraid of infection and dare not open the window to ventilate. What is the correct way? How do residents do a good job of disinfection at home, they do n’t know how to use 84 disinfection solution, and some people have symptoms of allergic sneezing for 84 disinfectant. What should I do in this regard? On September 22, at the 45th press conference of the new crown pneumonia's epidemic prevention and control work in the autonomous region, Hou Binbin, a member of the Autonomous Region Epidemic Prevention and Control Expert Group, deputy director and chief physician of the district Center for Disease Control and Prevention.

At present, it is believed that through the respiratory tract droplets and close contact, it is the main way to propagate the new crown pneumonia. In a relatively closed environment, it can be transmitted through gas solution, and items that are contaminated by viruses may also cause infection.

The purpose of opening window ventilation is to strengthen indoor and outdoor air circulation, and maximize the risk of closed environmental air -solicit -like transmission. Opening window ventilation can also keep the indoor air fresh, which is beneficial to improve physical immunity, thereby enhancing the ability to resist virus infection. Therefore, in most cases, we suggest that you can open more windows and ventilation under the conditions of the sunny weather and outdoor temperature to increase indoor air circulation, 2-3 times a day, 20-30 minutes each time. Pay attention when opening the window ventilation. Prevent and warm, avoid colds.

However, some special circumstances, such as the positive case rooms in the community are close to their own, there is a possibility of infection from the air from the case from the case to its own room. At this time, the windows should be opened carefully.

84 disinfectant is a chlorine -containing disinfection agent, which has strong corrosiveness and irritation. It has great irritation to human skin and mucous membranes. If you do not bring gloves directly to the raw fluid, it will cause the skin to have a slight pain. Especially if the concentration is too high, it will cause a strong stimulus effect on the mucosa of the respiratory tract, and the symptoms of sneezing will have a certain harm to health. We must read the instructions for details before using the 84 disinfection agent and use it according to the instruction manual. At the same time, we must do personal protection when used, and we cannot use it at the same time as the toilet cleaning to prevent toxic gases and endanger life. In addition, configure different concentrations according to the purpose of disinfection. Generally, 500mg/L 84 disinfectant solution can be used when prevention. Take 5%concentration 84 disinfectant as an example, that is, 990 ml of water (about 1 liter of water) adds 10 ml of disinfectant, and the surface of the objects with high -frequency contact (such as armrests, door handles, ground, desktop, etc.) spray or wipe it After 30 minutes of action, clean the water.

If the 84 disinfectant is unwell, alcohol can also be used for disinfection. The concentration of alcohol disinfection should be 60%-90%. 75%of alcohol should be most commonly used. The correct method is to disinfect the surface of the hand or small objects, spray or wipe the polluting items, such as hands, mobile phones, keyboards, door handles Wait, avoid contact infection. However, disinfection methods such as spraying alcohol in a large area and using alcohol disinfection in the kitchen are not desirable. At the same time, it is necessary to be careful when the alcohol is stored to avoid alcohol in a fire source and high heat environment to avoid fires. At the same time Alcohol allergies should be used with caution.

Here, warmly remind everyone that when disinfecting the air with disinfectants, it must be an uninhabited environment to avoid spraying disinfectants directly to people.
