Topic:

  • [pre-print, not peer-reviewed] Screening for SARS-CoV-2 by RT-PCR and antibody testing in a village in Germany that had been quarantined for six weeks after a SARS-CoV-2 outbreak found that only 53% of participants with previously confirmed SARS-CoV-2 infections had detectable antibodies. Overall, 8% of the inhabitants had a positive SARS-CoV-2 antibody test (based on two or more independent tests), of whom 38% had a previous SARS-CoV-2 PCR test.
