SARS-COV-2 Seroprevalence and Seroconversion Among Employees of the Universitair Ziekenhuis Brussel During the 2020 COVID-19 Outbreak (COVEMUZ)

2021年11月3日 更新者:Universitair Ziekenhuis Brussel

A novel zoonotic coronavirus was discovered in Wuhan (Hubei Province, China) mid-December 2019 and was named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus rapidly spread to the rest of the world, including Europe and explicitly affects the respiratory system, generating Coronavirus disease 2019 (COVID-19).

This study is a monocentric interventional prospective cohort study. After signing a written informed consent, participants will be recruited for questionnaire completion and blood sampling. Sample storage and analysis will be performed at the laboratory of microbiology of the UZ Brussel.

  • To document SARS-CoV-2 seroprevalence among employees of the UZ Brussel at day 0 (i.e. at beginning of the study, planned early May 2020), month 2 and month 5.
  • To document number of SARS-CoV-2 seroconversions among employees of the UZ Brussel over a period of 5 months.
