75% alcohol and 84 disinfectant are effective against the Delta strain and can effectively inactivate the virus. According to the Diagnostic and Treatment Plan for Neocoronavirus Pneumonia (Trial Ninth Edition), 75% alcohol and chlorine disinfectants are effective in inactivating the neocoronavirus. The Delta strain is a mutated neocoronavirus, but has the same biological characteristics as the original neocoronavirus strain. 84 disinfectant is a chlorine disinfectant, which is effective against the delta strain and can inactivate it effectively. In addition, 56 degrees Celsius for 30 minutes, ether, peracetic acid, and chloroform are all effective in inactivating the delta strain. Different disinfectants are suitable for different scenarios, for example, 75% alcohol can be used to disinfect skin surfaces and object surfaces, while 84 disinfectant can be used to disinfect a wide range of space, and some medical supplies can be disinfected by high temperature steaming, so choosing the appropriate disinfectant according to different scenarios can effectively inactivate the delta virus strain.
