The system used national registries that included data on LTCF residents, staff, COVID-19 laboratory results, causes of death, and vaccination. Clusters (≥3 residents or staff with positive SARS-CoV-2 test ≤14 days) were detected in 427 (43%) of 993 LTCFs. The authors concluded that automated national surveillance for SARS-CoV-2 clusters in Norway’s LTCFs is possible and has the potential for near real-time outbreak detection."}
