背景资料：越南实施了各种公共卫生干预措施，如接触者追踪和检测、强制隔离和封锁，以应对2019冠状病毒病（COVID-19）。然而，这些措施对疫情的影响仍不清楚。方法：本文描述了与COVID-19发病率相关的公共卫生干预措施。使用最大似然估计来评估遏制延迟（症状发作和开始隔离之间的时间），并使用多变量回归来确定干预措施与COVID-19发病率之间的相关因素。根据传递对计算有效繁殖数（Rt）。结果：针对这一流行病定期采取干预措施。总体而言，1474例COVID-19病例中有817例（55.4%）为输入性病例。基于8.72 ± 5.65天的连续间隔，估计在严格的边境控制和接触者追踪期间，Rt降至1以下（最低为0.02，95% CI 0-0.12），并在新的聚集性之前增加。随着时间的推移，发现病例的主要方法从被动通知转变为在移民局或封锁区主动发现病例，遏制延误显示出病例发现模式之间的显著差异。结论：早期、严格和持续实施的干预措施对控制COVID-19至关重要。能力有限的中低收入国家可以使用非药物干预措施成功遏制COVID-19。
Background: Vietnam implemented various public health interventions such as contact tracing and testing, mandatory quarantine, and lockdowns in response to coronavirus disease 2019 (COVID-19). However, the effects of these measures on the epidemic remain unclear. Methods: This article describes the public health interventions in relation to COVID-19 incidence. Maximum likelihood estimations were used to assess containment delays (time between symptom onset and start of isolation) and multivariable regression was employed to identify associated factors between interventions and COVID-19 incidence. The effective reproductive numbers (Rt) were calculated based on transmission pairs. Results: Interventions were introduced periodically in response to the epidemic. Overall, 817 (55.4%) among 1474 COVID-19 cases were imported. Based on a serial interval of 8.72 ± 5.65 days, it was estimated that Rt decreased to below 1 (lowest at 0.02, 95% CI 0–0.12) during periods of strict border control and contact tracing, and increased ahead of new clusters. The main method to detect cases shifted over time from passive notification to active case-finding at immigration or in lockdown areas, with containment delays showing significant differences between modes of case detection. Conclusions: A combination of early, strict, and consistently implemented interventions is crucial to control COVID-19. Low-middle income countries with limited capacity can contain COVID-19 successfully using non-pharmaceutical interventions.
