Local characteristics of cross-unit contamination around high-rise building due to wind effect: Mean concentration and infection risk assessment

► We examine cross-unit contamination around a high-rise building due to wind effect. ► The differences between open and closed window conditions are not significant. ► Mean concentration values decrease about one order of magnitude after window is open. ► Mean infection probabilities can up to 20% under closed-window condition. ► Infection risk calculated by instantaneous peak concentration value can be neglected.
