Coronavirus disease 2019 (COVID-19) became a pandemic within a matter of months. Analysing the first year of the pandemic, data and surveillance gaps have subsequently surfaced. Yet, policy decisions and public trust in their country's strategies in combating COVID-19 rely on case numbers, death numbers and other unfamiliar metrics. There are many limitations on COVID-19 case counts internationally, which make cross-country comparisons of raw data and policy responses difficult.
This paper presents and describes steps in the testing and reporting process, with examples from a number of countries of barriers encountered in each step, all of which create an undercount of COVID-19 cases. This work raises factors to consider in COVID-19 data and provides recommendations to inform the current situation with COVID-19 as well as issues to be aware of in future pandemics.
新冠肺炎（COVID-19）在数月内成为全球大流行。对大流行第一年进行分析后，随后出现了数据和监测方面的差距。然而，政策决策和公众对本国抗击 COVID-19 战略的信任取决于病例数量、死亡人数和其他不熟悉的指标。国际上对 COVID-19 病例的统计存在诸多限制，这使得对原始数据和政策应对措施进行跨国比较变得困难。
本文提出并描述了检测和报告流程中的步骤，并以一些国家为例说明了在每个步骤中遇到的障碍，所有这些都导致了 COVID-19 病例的漏报。这项工作提出了在 COVID-19 数据中需要考虑的因素，并为当前的 COVID-19 情况提供了建议，以及在未来的大流行中需要注意的问题。
