Determination of SARS-COV-2 seroprevalence in the departaments of Colombia Determinación de la Seroprevalencia de SARS-CoV-2 en los departamentos de Colombia

Abstract

Introduction: in the present times, the COVID-19 pandemic is one of the greatest challenges on a global scale. Since the beginning of the epidemic outbreak in Wuhan, (China), until the spread of Sars-CoV-2 in about 192 countries, humanity has been exposed to a highly contagious and lethal virus, with more than 176.3 million cases and 3.8 million deaths worldwide. Objective: to calculate the seroprevalence for SARS-CoV-2 in the departments of Colombia. Methodology: Data was obtained from the daily SARS-Cov-2 infection and deaths reports provided by the National Institute of Health. Results: it was determined that the departments with the highest seroprevalence (proportion of persons with detectable antibodies) for COVID-19 were: Bogotá (0.15), San Andres and Providencia (0.1), Atlantico (0.1), Antioquia (0.09), Quindio (0.08) and Caldas (0.08).  The departments with the lowest seroprevalence for COVID-19 were: Choco (0.02), Vichada (0.02), Arauca (0.03), Cauca (0.03), Cordoba (0.04) and Guainia (0.04). Conclusion: the development of this research allowed us to achieve a thorough understanding of the progress of COVID-19 seroprevalence in the country as of June 20 2021. This information is beneficial to establish the key characteristics of the transmission of this virus and to perceive its geographic dispersion, severity and impact on the community.
