Abstract This study investigates the presence of SARS-CoV-2 in indoor and outdoor environments two cities Norway between April May 2022. With lifting COVID-19 restrictions country a focus on vaccination, this research aims to shed light potential for virus transmission various settings. Air sampling was conducted healthcare non-healthcare facilities, covering locations frequented by individuals across different age groups. The found that out 31 air samples, only four showed RNA RT-qPCR, with no viable detected after RNAse pre-treatment. These positive samples were primarily associated involving children elderly. Notably, sequencing revealed mutations increased infectivity one samples. results highlight importance considering as sources transmission, especially settings prolonged exposure. As vaccination coverage increases globally, still representing substantial unvaccinated population, emphasizes need re-implement mask-wearing mandates indoors public transport reduce transmission. findings have implications health strategies control COVID-19, particularly face new variants during autumn winter seasons.
