FIGURE 3.

Antiviral activity of various concentrations of hypochlorous acid (HClO) against severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) in the presence of 0.1% FBS. SARS‐CoV‐2 cultured in DMEM supplemented with 2% FBS was treated with 29.7, 59.4, 119 or 238 ppm of HClO for 10 (), 30 () s, 1 () or 3 () min followed by determination of virus titer with 50% tissue culture infective dose. All data represent the means + SD from three independent experiments. Dot line indicates detection limit for experiment. * indicates that values are significantly different between phosphate‐buffered saline (PBS) and each experimental condition
