Fig. 3: Infectivity of the Delta and Omicron VOCs across a range of RH and CO2(g) concentrations.

a Infectivity of the Delta and Omicron BA.2 variants at 15 s in ambient air as a function of relative humidity. b Infectivity of the Delta variant at 15 s as a function of relative humidity and [CO2(g)]. Values are means ± SE. A two-way ANOVA of the data in (b) indicated that both CO2(g) and RH are significant factors in predicting infectivity, but do not interact, meaning the effect of CO2(g) is similar at different RHs (all 80% and below). P-values: RH 0.016, CO2(g) < 0.0001, n = 169 (independent samples). Source data are provided as a Source Data file.
