Visual analysis of the prevention and control measures of COVID-19 in Chinese ports

Abstract

In 2022, COVID-19 solutions in China has entered a normal stage, and the solutions imported from ports have been transformed from emergency prevention and control measures to investigative long-term prevention and control measures. Therefore, it is necessary to study solutions for COVID-19 at border ports. In this study, literature related to COVID-19 prevention and control at ports from 2020 to September 2022 in the Wanfang database, CNKI, CQVIP database, and WOS core were searched. Citespace 6.1.R2 software was used for the visual analysis of researchers, research institutions, and keywords. A total of 170 articles were included for analysis. The research teams of the Chinese Academy of Inspection and Quarantine (CAIQ) and Beijing Customs District P.R.CHINA published more articles, and there was less cross-cooperation among research institutions. Keywords such as “COVID-19”, “epidemic prevention and control”, “port”, and “health quarantine” appear frequently. High-frequency clustering words were “#0 COVID-19”, “#1 risk assessment”, “#2 prevention and control mechanism”, “#3 infectious diseases”, “#4 public health”, and so on, indicating that risk assessment and other prevention mechanisms were the hot spots of current research.
