The monitoring system on Polish mink farms detected SARS-CoV-2 infection first in January 2021 and has been kept in place since then.<h4>Material and methods</h4>Oral swab samples collected between February 2021 and March 2022 from 11,853 mink from 594 farms in different regions of Poland were screened molecularly for SARS-CoV-2. Isolates from those with the highest loads of viral genetic material from positive farms were sequenced and phylogenetically analysed. Serological studies were also carried out for one positive farm in order to follow the antibody responJournal of veterinary research449-458https://www.ebi.ac.uk/biostudies/studies/S-EPMC9944996biostudies-literatureSARS-CoV-2 Monitoring on Mink Farms in Poland.PMC9944996Rola JDomanska-Blicharz KGiza ASocha WTrebas PIwan EKawiak-Sadurska MOpolska JBomba AOrlowska ANiemczuk KMunnink BOSmreczak MKoopmans MLisowska AfalseSARS-CoV-2 Monitoring on Mink Farms in Poland.<h4>Introduction</h4>Many countries have reported severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infections in mink, and transmission back to humans has raised the concern of novel variants emerging in these animals.
