The coronavirus disease 2019 (COVID-19) pandemic has spread rapidly around the globe. Even though multiple strategies are available for controlling infectious respiratory diseases, the current approach for managing this pandemic is the prevention of person-to-person transmission. Despite the quarantine strategy, some work positions must remain active, such as airport personnel.
To identify risk factors for COVID-19 transmission among workers at the El Dorado, Luis Carlos Galán Airport from March to July 2020.
This is a prospective cohort study with workers of the El Dorado International Airport, in Bogotá, Colombia. A sociodemographic questionnaire was for searching for symptoms associated with COVID-19 and other risk factors. Nasopharyngeal swabs were collected for determining the presence of COVID-19. In order to identify seroconversion, we used an automated chemiluminescent immunoassay for anti-SARS-CoV-2 IgM and IgG antibodies. Patients with positive results were followed-up for 21 days.
We observed an incidence of infection of 7.9%; most cases were asymptomatic. The main risk factor associated with infection was the duration of daily commute (relative risk 1.02 [95% confidence interval, 1.002-1.041]).
We observed asymptomatic infection by COVID-19 among airport workers. Future research should contribute with knowledge for developing strategies that guarantee the protection of airport workers.
2019年冠状病毒病（COVID-19）大流行已在全球迅速蔓延。尽管有多种控制传染性呼吸道疾病的策略，但当前应对这一大流行的方法是预防人际传播。尽管采取了隔离策略，但一些工作岗位仍必须保持运转，比如机场工作人员。
确定2020年3月至7月在埃尔多拉多的路易斯·卡洛斯·加兰机场工作人员中COVID-19传播的风险因素。
这是一项针对哥伦比亚波哥大埃尔多拉多国际机场工作人员的前瞻性队列研究。通过一份社会人口统计学调查问卷来寻找与COVID-19相关的症状及其他风险因素。采集鼻咽拭子以确定是否存在COVID-19。为了确定血清转化情况，我们使用了一种用于检测抗SARS-CoV-2 IgM和IgG抗体的自动化化学发光免疫分析法。对检测结果呈阳性的患者进行了21天的随访。
我们观察到感染发生率为7.9%；大多数病例无症状。与感染相关的主要风险因素是每日通勤时长（相对风险1.02 [95%置信区间，1.002 - 1.041]）。
我们在机场工作人员中观察到了COVID-19无症状感染情况。未来的研究应为制定保障机场工作人员安全的策略提供知识支持。
