Children generally lack immunity to the new coronavirus, but fat solvents such as ether, 75% ethanol, chlorine disinfectants, peracetic acid and chloroform are effective in inactivating the virus, so good disinfection can prevent the disease to a certain extent. It is recommended to use chlorine disinfectant and peroxyacetic acid disinfectant to clean and disinfect frequently touched items such as tables, chairs, benches and bedside tables frequently every day. Tableware should be cleaned with detergent and water after use, and hands should be washed frequently before and after meals. For hands and skin, it is recommended to choose effective disinfectants such as iodophor, chlorine disinfectants and hydrogen peroxide disinfectants for hand and skin or quick-drying hand disinfectants to wipe and disinfect.
