The survival time of each virus on the surface of the object is different, such as influenza virus can survive on the surface of the object for about 48 h. Coronavirus can survive on the surface of the object for more than 1 week, but these viruses are sensitive to ultraviolet light and heat, 56 ℃ for 30 minutes, ether peroxide, acetic acid, 75% ethanol, chlorine-containing agents, chloroform and other fat solvents are able to kill the virus. Studies have shown that these viruses can be effectively inhibited within 1 minute, so you can use the above items to disinfect your hands after touching a patient or the surface of a contaminated object. In addition, it is possible to be infected by touching the nose, mouth or eyes after touching contaminated objects or surfaces, mainly through respiratory droplets or close contact.
