Microbe(s): influenza, coronavirus, SARS-CoV-2, COVID-19
Slightly acidic hypochlorous acid waters (SAHWs) with pH of 5.25.8 containing different concentrations of free available chlorine – 62, 119, 220, 300, and 540 ppm (SAHW-62, -119, -220, -300, and -540, respectively) – were evaluated for their virucidal activity toward a low pathogenic H7N1 avian influenza virus (AIV) and an infectious bronchitis virus (IBV) in suspension, abiotic carrier, and direct spray tests, with the presence of organic materials. In the carrier test, the plastic carriers, while viruses remained in the wipes. Besides, a small volume of sprayed SAHW was effective against the viruses on the rayon sheets for daily cleaning in the application area. The findings we obtained concerning IBV might basically be applicable in relation to SARS-CoV-2, given the resemblance between the two viruses.
