A simple mouth and nose spray could act as an effective shield to protect against COVID-19, adding one more tool to the arsenal of antiviral options. The straightforward solution was recommended by Dr. Mostafa Kamal Arefin of Dhaka Medical College & Hospital in Bangladesh and includes polyvinyl pyrrolidone or povidone iodine (PVP-I), a microbicidal agent with a virucidal efficacy of 99.99%.1
Writing in the Indian Journal of Otolaryngology and Head & Neck Surgery, Arefin recommended the PVP-I oro-nasal spray for health care workers and anyone else to help prevent COVID-19,2Â echoing a number of other studies that have also found benefits to gargling, nasal irrigation and nebulization of PVP-I and other compounds, including Lugolâs iodine, saline and hydrogen peroxide.3
