There is no evidence that p-chloro-m-xylenol kills neocoronaviruses and is not recommended as a neocoronavirus disinfectant. P-chloro-m-xylenol, is a broad-spectrum antimicrobial for mold and mildew. P-chloro-m-xylenol kills most gram-positive and gram-negative bacteria, as well as fungi and molds, and is used in hospitals as a disinfectant for skin and surgical instruments, but has very limited effect on coronaviruses. According to the Diagnostic and Treatment Plan for Pneumonia Infected by Novel Coronavirus, the new coronavirus is heat sensitive and can be effectively inactivated by heat, ether at 56°C for 30 minutes, ether, 75% ethanol, chlorine disinfectants, lipid solvents such as peracetic acid and chloroform, of which chlorhexidine is not effective in inactivating the virus. P-chloro-m-xylenol is a halogenated phenolic disinfectant, not a chlorinated disinfectant, and there are no experimental studies to show that p-chloro-m-xylenol can inactivate the new coronavirus. Therefore, for Neocoronavirus, it is recommended to choose chlorine-containing disinfectant, such as 84 disinfectant diluted as an environmental disinfectant, and the use of which needs to avoid mixing with other disinfectants. In addition, 75% ethanol can be used as a hand disinfectant or wipe disinfectant, avoiding spraying large areas, which can easily cause fires.
