Sept. 17 (UPI) -- A commercially available nasal antiseptic solution "inactivates" COVID-19 just 15 seconds after the coronavirus is exposed to it, effectively preventing the infection from developing, according to a study published Thursday by JAMA Otolaryngology-Head & Neck Surgery.By inactivating the virus, the antiseptic nasal rinse -- a povidone-iodine solution administered in the nostril -- also would help prevent those infected from spreading it to others, the researchers said....Researchers have yet to study the rinse in humans with COVID-19, although a small phase 4 clinical trial is scheduled to start in October."A low dose povidone-iodine nasal antiseptic inactivates [COVID-19] after only 15 seconds of contact time," study co-author Dr. Samantha Frank told UPI.
