1. The research issued by the Bonn University Hospital
The research issued by the Bonn University Hospital and made by the group of scientists including Prof. Dr. Hendrik Streeck (Institute of Virology), Prof. Dr. Gunther Hartmann (Institute for Clinical Chemistry and Clinical Pharmacology, Spokesman for the Cluster of Excellence ImmunoSensation2), Prof. Dr. Martin Exner (Institute for Hygiene and Public Health), Prof. Dr. Matthias Schmid (Institute for Medical Biometry, Computer Science and Epidemiology).
In the framework of the research, all residents of Germany's Gangelt were tested on the existence of SARS-CoV-2 infection and antibodies to SARS-CoV-2.
Gangelt is one of the most COVID-19-affected German municipalities. It is believed that the outbreak was caused by the carnival held on February 15, 2020. After the event, several people tested positive for SARS-CoV-2.
Preliminary result: the existing immunity was determined at about 14% (IgG against SARS-CoV2, method specificity>, 99%). About 2% of people had current SARS-CoV-2 infection detected by the method of polymerase chain reaction (PCR). The overal infection rate (the presence of a current infection or antibody in the body) was about 15%. The mortality (mortality rate), based on the total number of infected people in the Gangelt community, is approximately 0.37% based on the preliminary data of this study. The mortality rate based on the total population in the Gangelt is currently 0.06%.
