Some "disinfection cards" mention that they can replace masks and are suitable for children to wear, which is easy to mislead consumers and has many security risks.
"At present, the epidemic is not over yet, and wearing a mask is still an effective protection method. You can't blindly believe in the efficacy of some' disinfection cards'. " These so-called universal "disinfection cards" are not only equally effective, but also counterproductive when used improperly, causing safety problems. Yang Renguo, a doctor of infectious diseases at Sichuan Provincial People's Hospital, said.
Do these universal "disinfection cards" really work wonders?
In this regard, Luo, a staff member of the Health Department of Ziyang CDC in Sichuan, said that chlorine dioxide is a broad-spectrum disinfectant with strong oxidation ability, good disinfection effect and low residue. However, some "disinfection cards" advertised that "chlorine dioxide is released after contact with moisture in the air" is obviously wrong, and chlorine dioxide can only play a role in aqueous solution.
"Chlorine dioxide undergoes an instantaneous redox reaction under the specific conditions of water and organic matter, producing an intermediate product oxygen free radical and a final product chloride ion. This kind of free radical has a strong oxidation effect, and it is this kind of free radical that finally produces disinfection effect. Therefore, it cannot be disinfected by releasing chlorine dioxide. "
Everyone is the first person responsible for his health. In the face of epidemic situation, scientific and standardized wearing of masks is an effective measure to prevent infection.
