Evaluation of antiseptic antiviral activity of CHX and HXM on the HCoV 229E. This figure shows the log10 reduction in viral titers obtained after the action of chlorhexidine (CHX) and hexamidine (HXM) at different concentrations and at specified contact times: (A) represents the log10 reduction in Human coronavirus 229E (HCoV 229E) titers obtained after action of CHX at 10−3 mol L−1 (Inline graphic) and 10−4 mol L−1 (Inline graphic) and (B) represents the log10 reduction in HCoV 229E titers obtained after action of HXM at 10−3 mol L−1 (Inline graphic). The bold line in both graphs represents the threshold of 4 log10 reduction to reach to pretend to an antiviral antiseptic activity.
