Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Abstract

Background: Epidemiologic surveillance of COVID-19 is essential to collect and analyze data to improve public health decision making during the COVID-19 pandemic. There are few initiatives led by public–private alliances in Colombia and Latin America. The CoVIDA study led by Universidad de los Andes contributed with RT-PCR tests for SARS-CoV-2 in population groups with mild or asymptomatic infections in Bogotá. The present study aimed to determine the factors associated with SARS-CoV-2 infection in working adults.

Methods: COVID-19 sentinel epidemiological surveillance study, from April 18, 2020 to March 29, 2021. The study included people aged 18 years or older without a history of COVID-19. Priority for inclusion was given to two main occupational groups working during the pandemic: health care workers and essential services workers with high mobility in the city. Social, demographic, and health-related factors were collected via phone survey. Afterward, the molecular test was conducted to detect SARS-CoV-2 infection.

Findings: From 58,638 participants included in the study, 3,310 (5·6%) had a positive result for SARS-CoV-2 infection. A positive result was associated with the age group (18-29 years), living with more than three cohabitants, living with a COVID-19 confirmed case, having no affiliation to the health system, reporting a very low socioeconomic status, and having essential occupations.

Interpretation:The CoVIDA study showed the importance of intensified epidemiological surveillance to identify groups with increased risk of infection. These groups should be prioritized in the screening, contact tracing, and vaccination strategies of the city to contribute to the pandemic mitigation.

Funding: The CoVIDA study was funded through donors managed by the philanthropy department of Universidad de los Andes.

Declaration of Interests: The authors declare no conflicts of interest.

Ethics Approval Statement: Ethics approval was obtained from the ethics committee of Universidad de los Andes (2020; Approval No. 1181).

Keywords: SARS-CoV-2, sentinel surveillance, risk factor, socioeconomic factors, COVID-19 RT-PCR Testing, Colombia
