Effect of common bleach disinfection of Ebola virus in A) dried cell culture medium, B) wet blood, and C) dried blood. Coupons were spotted with Ebola virus/Makona (EBOV/Mak). Bleach solutions (0.5% or 1.0% hypochlorite) were effective in reducing the titer of EBOV/Mak to the assay LLOQ in dried cell culture medium or wet blood. Incomplete disinfection was observed when virus was suspended in blood and dried for 1 h before disinfection. Data were confirmed for dried cell culture medium and dried blood studies at an independent laboratory (DSTL). Error bars indicate SD. *Significant difference (p<0.05) between control and disinfected samples.
