Preventing the new coronavirus from disinfecting itself
At the moment, the new coronavirus is raging, and various countries and regions have begun to take some preventive measures. For ordinary people, take some daily preventive measures, wear masks when traveling, wash their hands before meals and logistically, and regularly live and live in an environment. Disinfection is a very effective method. So what kind of disinfection is more effective?
Coronavirus is a type of RNA virus with an envelope. When the envelope is destroyed by a disinfectant, the RNA is also very easily degraded, thereby inactivating the virus. Because of this envelope, the coronavirus is sensitive to organic solvents and disinfectants. Therefore, methods such as 75% alcohol, ether, chloroform, formaldehyde, chlorine-containing disinfectants, peracetic acid, and ultraviolet rays can all inactivate the virus.
So what are the specific disinfection methods? First of all, let us take a look at hand disinfection. While doing personal protection, pay special attention to hand hygiene. Currently, the hand disinfectant recommended by WHO is ethanol with a content of 70% to 75%, and there is no obvious dirt. In the case of, use the seven-step handwashing method to disinfect hands with ethanol hand disinfectant. If there is obvious dirt, wash it with running water and hand sanitizer, and then use hand disinfectant for disinfection after drying.
Secondly, for the surface disinfection, it is recommended to use effervescent disinfectant tablets or 84 disinfectant. For example, effervescent tablets contain 500mg of available chlorine per tablet, which can be self-dissolved in water and is more convenient to use. Generally, put 1 or 2 tablets in 1L of water. It can be used for surface disinfection of objects in this epidemic. The editor here reminds everyone that the 84 disinfectant must be prepared according to the instructions carefully due to different manufacturers.
The latter is the air disinfection machine. Air disinfection has limited effect in the control of respiratory infectious diseases. It is meaningful for terminal disinfection after confirmed or suspected cases are transferred. It is recommended that professional health personnel use peroxygen without people. Acetic acid or hydrogen peroxide treatment or mobile UV disinfection treatment. Under normal circumstances, it can be carried out by means of enhanced ventilation and the use of a qualified air disinfection machine.
