Povidone-Iodine Nasal Antiseptic Shows Rapid Inactivation of SARS-CoV-2 in Laboratory Study
As the COVID-19 pandemic underscored the urgency of infection control, researchers turned their attention to povidone-iodine (PVP-I)—a well-established antiseptic with broad-spectrum antimicrobial properties. In this in vitro study, scientists sought to determine how effectively PVP-I nasal antiseptics could inactivate SARS-CoV-2, the virus responsible for COVID-19, in extremely short contact times.
