Abstract:
Objective To assess the global epidemic of Coronavirus disease 2019(COVID-19) in May 2021 and the risk of importation.
Methods According to the daily COVID-19 data publicly released by Johns Hopkins University, combined with the policy stringency index published by the University of Oxford, an epidemiological description method was used to provide a comprehensive and timely assessment of the global epidemic risk through a general overview, a comprehensive assessment of the epidemic trends in WHO regions and key countries, as well as a comprehensive analysis of the epidemic and prevention and control policies in 14 neighbouring countries. The assessment results for each country are expressed as "countries of global concern", "countries of the general concern in each WHO sub-region" and "neighbouring countries of special concern".
Results Compared with April 2021, the number of confirmed cases decreased by 14.11% and deaths decreased by 6.60% globally in May 2021. The growth rates of newly confirmed and death cases in Southeast Asia increased continuously, thus the region needs critical concern. The time taken for every 10 million new confirmed cases globally showed overall increasing trend, and the time taken for every 500 000 new deaths decreased. In many countries, the growth rate of newly confirmed cases exceeded 100% in May 2021. Afghanistan and Kyrgyzstan are countries of special concern among the 14 land-bordering countries.
Conclusion Since May, the infections eased slightly. The number of new confirmed cases and deaths has decreased except in Southeast Asia and Western Pacific. Although the global growth rate of confirmed cases and deaths are showing downward trend, it is necessary to continuously monitor the countries with global concern like India,Argentina,Columbia and Nepal, paying attention to the changes of its epidemic situation and prevention and control policies, and establish a communication mechanism with relevant agencies and provide timely warnings.
