Affordable measures to monitor and alarm nosocomial SARS-CoV-2 infection due to poor ventilation.

ABSTRACT: Since the coronavirus disease 2019 (COVID-19) outbreak, the nosocomial infection rate worldwide has been reported high. It is urgent to figure out an affordable way to monitor and alarm nosocomial infection. Carbon dioxide (CO₂ ) concentration can reflect the ventilation performance and crowdedness, so CO₂ sensors were placed in Beijing Tsinghua Changgung Hospital's fever clinic and emergency department where the nosocomial infection risk was high. Patients' medical records were extracted to figure out their timelines and whereabouts. Based on these, site-specific CO₂ concentration thresholds were calculated by the dilution equation and sites' risk ratios were determined to evaluate ventilation performance. CO₂ concentration successfully revealed
