Official Title
COvid-19 National Survey for Assessing VIral Spread by Nonaffected CarriErs (CON-VINCE)
Brief Summary

CON-VINCE (COvid-19 National survey for assessing VIral spread by Non-affected CarriErs) is a national, monocentric, and longitudinal study aiming to evaluate the spread dynamics of the COVID-19 disease within the Luxembourgish population. Participants who are clinically asymptomatic or present with only mild symptoms will be followed up longitudinally, regularly tested for SARS-CoV-2 by RT-PCR, antibody status, and subjected to an epidemiological, clinical and biological phenotyping to better understand the nature, dynamics of infectivity and spread of the virus in the population. CON-VINCE will also track the psychological and socio-economic impact of long-term containment measures on the general population.

Detailed Description

To capture the dynamics and impact of the virus spread in the Luxembourgish population, data and sample collection is done every two weeks for two months (4 times in total) with a final follow-up one year after the participant's inclusion in the study. Participants complete questionnaires before each sample collection. The baseline questionnaire captures demographic data, medical history, behavioral and psychological data, and socio-economic status. Participants provided information on medical history, history of allergies, smoking, and chronic medication taken regularly. COVID-19-related data and environmental conditions of the household were obtained.
