COVID: nasal antiseptic kills virus??
Dilute solutions of povidone-iodine inactivate SARS-CoV-2 virus and may be usable for nasal antisepsis ( see covid nasal antiseptic jamaotol2020 in dropbox, or doi:10.1001/jamaoto.2020.3053) Details: --SARS-CoV-2 virus (strain USA-WAI/2020) viability was tested against aqueous povidone-iodine (PVP-I) solutions diluted to concentrations of 0.5%, 1.25% and 2.5%, and compared to controls ( 70% ethanol as a positive control and water as a negative one) --the virus was incubated at room temperature (22 deg C) for 15-30 seconds --the resulting solutions of virus plus the various dilutions of PVP-1 and controls were then cultured and titers measured --primary outcome: log reduction after 15 seconds and 30 seconds; surviving virus was quantified and compared with the negative water control Results: --at 15 seconds: --all 3 PVP-I concentrations completely inactivated SARS-CoV-2 within 15 seconds: --th...
