这项研究的目的是基于越南一个大省北宁省2021年的流行病学数据和政策行动，分析与越南政府政策变化有关的新冠肺炎传播的变化模式。收集了2021年1月至12月确诊病例的数据，以及政策文件。2021年期间，北宁省出现了三个不同的新冠肺炎大流行时期。在第一个时期，即“零新冠疫病”时期(01/04-07/04/2021)，人口接种率很低，只有不到25%的人口接种了第一剂疫苗。在此期间实施的措施侧重于国内行动限制、口罩强制要求和筛查工作，以控制病毒的传播。随后的时期被称为“过渡期”(2021年7月5日至22日10月)，见证了人口接种覆盖率的显著增加，80%的人口接种了第一剂疫苗。在此期间，几天过去了，社区没有任何新冠肺炎病例报告。当地政府采取措施管理国内行动，减少隔离时间，并鼓励对与新冠肺炎有密切接触的病例进行居家隔离。最后是“新常态”阶段(2021年10月23日至12月31日)，在此期间，人群第二针疫苗接种率提高到70%，防治新冠肺炎的大部分任务减少。总之，这项研究强调了政府政策在管理和控制新冠肺炎传播方面的重要性，并为在类似背景下制定现实的和特定于背景的策略提供了见解。
The aim of this study is to analyse the changing patterns in the transmission of COVID-19 in relation to changes in Vietnamese governmental policies, based on epidemiological data and policy actions in a large Vietnamese province, Bac Ninh, in 2021. Data on confirmed cases from January to December 2021 were collected, together with policy documents. There were three distinct periods of the COVID-19 pandemic in Bac Ninh province during 2021. During the first period, referred to as the ‘Zero-COVID’ period (01/04–07/04/2021), there was a low population vaccination rate, with less than 25% of the population receiving its first vaccine dose. Measures implemented during this period focused on domestic movement restrictions, mask mandates, and screening efforts to control the spread of the virus. The subsequent period, referred to as the ‘Transition’ period (07/05–10/22/2021), witnessed a significant increase in population vaccination coverage, with 80% of the population receiving their first vaccine dose. During this period, several days passed without any reported COVID-19 cases in the community. The local government implemented measures to manage domestic actions and reduce the time spent in quarantine, and encouraged home quarantining for the close contacts of cases with COVID-19. Finally, the ‘New-normal’ stage (10/23–12/31/2021), during which the population vaccination coverage with a second vaccine dose increased to 70%, and most of the mandates for the prevention and control of COVID-19 were reduced. In conclusion, this study highlights the importance of governmental policies in managing and controlling the transmission of COVID-19 and provides insights for developing realistic and context-specific strategies in similar settings.
