From: Persistence of two coronaviruses and efficacy of steam vapor disinfection on two types of carpet
Efficacy of steam vapor against two coronaviruses on nylon carpet. Data are expressed as mean ± standard deviation (SD) from ten replicates in two trials. The dash lines indicate the detection limit for titer reduction (BCoV >3.0, HCoV OC43 >3.2 log10 TCID50/coupon). The p-value among treatments for each virus was ≥ 0.05 (ns), < 0.01 (**) and < 0.0001 (****)
