閉鎖空間におけるウイルスの濃度をモデル化するためのリスク評価ツール。
CARA is a risk assessment tool developed to model the concentration of viruses in enclosed spaces, in order to inform space-management decisions. It does this by simulating the long-range airborne spread SARS-CoV-2 virus in a finite volume, assuming homogenous mixing, and it estimates the risk of COVID-19 airborne transmission therein.
