During the last two years, hundreds of millions people in world have been infected with SARS-CoV-2 due to recurrent waves and closed spaces. Daycare centers are critical infrastructures that cannot be replaced, even during COVID-19 period. However, existing settings daycare may pose risks inevitable close contact between teachers children, as well fomite airborne transmission care hours. Therefore, reinforced mitigation strategies applied reduce potential indoor virus transfer many countries. numerous outbreaks reported centers. this study, researchers focused on risk behavior long-distance based detected viruses air purifier filter sampling a center outbreak Korea. Various experiments possible situations were conducted nursing rooms field interviews. The monitored aerosol-sized particles visualized particle at center. results study revealed is under current center, flush-out can an important countermeasure ventilation methods prevent spread purifiers represented should properly installed operated by airflow occupied findings will contribute understanding development customized measures for
