Disinfectant effervescent tablets can kill coronavirus, but not all of them can achieve this effect. The 9th edition of the New Coronary Pneumonia Diagnostic and Treatment Guidelines mentions that the new coronary virus can be sterilized by ether, 75% ethanol, chlorine disinfectants, peracetic acid and chloroform, etc. Therefore, if the effervescent tablets used contain such ingredients, and the active ingredient meets the disinfection requirements, they can be used as disinfectant. However, not all effervescent tablets can meet such disinfection requirements, such as chlorhexidine for the new coronavirus can not meet the disinfection requirements, so the use of effervescent tablets for the disinfection of the new coronavirus can not guarantee the disinfection effect, and is not recommended as the main means. Purchase 84 disinfectant or 75% alcohol disinfectant, can effectively kill the virus and relatively good operation.
