The new coronavirus is coming so fiercely, everyone is panicked. With more and more confirmed cases, personal protection has also received unprecedented attention. In addition to the repeated emphasis on wearing masks and washing hands frequently, disinfection has also become a topic of concern. Look at the shopping online. Alcohol and 84 disinfectant are all sold out. What else can we choose besides these two?
Let's take a look at the introduction in the pneumonia diagnosis and treatment plan for the new coronavirus infection (trial version 4). Viruses are sensitive to ultraviolet rays and heat. At 56°C for 30 minutes, ether, 75% ethanol, chlorine-containing disinfectants, peracetic acid and chloroform and other lipid solvents can effectively inactivate the virus, but chlorhexidine cannot effectively inactivate the virus.
Oh, it turns out that the hydrogen peroxide we usually use in the hospital is not in it. Can it work?
Hydrogen peroxide, also called hydrogen peroxide, is a strong oxidant. When treating abrasions in the hospital, a medical hydrogen peroxide solution with a concentration of 3.0% is used for disinfection. Therefore, a certain concentration of hydrogen peroxide solution (such as 3.0% concentration) has a clear effect on disinfection and sterilization. The killing effect of hydrogen peroxide on bacteria and viruses is mainly derived from its strong oxidizing property. When hydrogen peroxide comes into contact with microorganisms, it can quickly decompose new ecological oxygen, and the new ecological oxygen enters the microorganisms to make bacteria The related enzymes are denatured, or destroy the nucleic acid structure of the virus, thereby killing the bacteria and inactivating the virus.
So can hydrogen peroxide effectively kill the new coronavirus? The answer is yes. Like peracetic acid, it destroys the nucleic acid structure of the virus through strong oxidizing properties, thereby achieving an oxidizing disinfectant that inactivates the virus. Peracetic acid can kill the coronavirus, and hydrogen peroxide can of course.
