OBJECTIVES
To determine the prevalence of SARS-CoV-2 detection among international travellers to Ghana during mandatory quarantine.
DESIGN
A retrospective cross-sectional study.
SETTING
Air travellers to Ghana on 21 and 22 March 2020.
PARTICIPANTS
On 21 and 22 March 2020, a total of 1,030 returning international travellers were mandatorily quarantined in 15 different hotels in Accra and tested for SARS-CoV-2. All of these persons were included in the study.
MAIN OUTCOME MEASURE
Positivity for SARS-CoV-2 by polymerase chain reaction.
RESULTS
The initial testing at the beginning of quarantine found 79 (7.7%) individuals to be positive for SARS-CoV-2. In the exit screening after 12 to 13 days of quarantine, it was discovered that 26 of those who tested negative for SARS-CoV-2 in the initial screening subsequently tested positive.
CONCLUSIONS
Ghana likely averted an early community spread of COVID-19 through the proactive approach to quarantine international travellers during the early phase of the pandemic.
FUNDING
None.
目的
确定在加纳强制检疫期间入境加纳的国际旅行者中 SARS-CoV-2 的检出率。
设计
回顾性横断面研究。
地点
2020 年 3 月 21 日和 22 日抵达加纳的航空旅行者。
参与者
2020 年 3 月 21 日和 22 日，共有 1030 名返回的国际旅行者在阿克拉的 15 家不同酒店被强制隔离并接受 SARS-CoV-2 检测。所有这些人都被纳入了这项研究。
主要观察指标
聚合酶链反应检测 SARS-CoV-2 的阳性率。
结果
在隔离开始时的初步检测中，发现 79 名（7.7%）个体 SARS-CoV-2 检测呈阳性。在 12 至 13 天隔离后的出口筛查中，发现最初筛查 SARS-CoV-2 检测呈阴性的 26 人随后检测呈阳性。
结论
加纳通过在大流行早期主动对国际旅行者进行检疫，可能避免了 COVID-19 的早期社区传播。
