Abstract

This study experimentally investigated the sized-resolved survivability of phi6 in aerosols sized from 0.65 to 10 μm under different temperature and relative humidity (RH) using an environmental chamber. A six-stage Anderson cascade impactor (ACI) with liquid medium was used to collect the phi6 aerosols. Viral titer and particle number were measured to calculate survivability. Experimental results showed that the infectivity and survivability of phi6 aerosol at 20°C/50% and 30°C/70% were the highest and lowest cases, respectively, among all tested conditions across all six stages of ACI. Considerable infectivity and survivability differences in aerosol sizes alerted the preventions on specific-sized virus-laden aerosol transmission. U-shaped dependence on RH at 25°C and 30°C was observed in both infectivity and survival of phi6 and 70% RH was suspected to be a weakness for phi6 survival.
