There are currently three modes of transmission of novel coronavirus, namely droplet transmission, close contact transmission and aerosol transmission. Among them, close contact transmission is also a form of transmission that should not be ignored. One may come into contact with the patient and may also come into contact with contaminated objects, such as towels, teacups, basins, cutlery, elevator buttons and door handles are all objects that may be contaminated. There are also vegetables and meat, especially in meat the virus will survive longer. Therefore, it is important to be aware that these items may also be potentially at risk of contamination.
