Previously, the new cases of Omicron variant infection in Shenzhen and Zhuhai were speculated to be spread by international express. However, infection through international express was still a corollary, and there was no conclusive evidence that these cases were caused by contact with objects. A number of disease control experts also said that although the virus can spread through the surface in a very short time, there is insufficient evidence to spread through the surface after a long time.
