Can We Repurpose Povidone-Iodine to Prevent COVID-19? A Review Explores the Science and Strategy

Povidone-iodine (PVP-I) has long been a staple in surgical suites and wound care, but could it serve a bigger purpose—like helping prevent COVID-19 in everyday life? A recent narrative review dives deep into the antiviral properties, mechanisms, and clinical potential of PVP-I, especially when used in the nose and throat. If you’re wondering how a common antiseptic might reduce infection risk in high-exposure settings, this one’s for you.

Povidone-Iodine as a Frontline Shield

As the COVID-19 pandemic unfolded, healthcare systems faced a dual crisis: protecting vulnerable patients while safeguarding the frontline workers delivering essential care. For providers involved in high-risk procedures—particularly in head and neck oncology—exposure to aerosolized viral particles became a serious occupational hazard. In response, a team of physicians from Johns Hopkins and the University of Pittsburgh proposed an innovative, low-cost, and easily deployable strategy: using povidone-iodine (PVP-I) as a topical antiseptic shield for the nasal and oral cavities.

SARS-CoV-2’s Journey Through the Airways

Published in Cell (2020), the study by Hou et al. delivers one of the most comprehensive looks at how SARS-CoV-2 infiltrates the human respiratory tract. By leveraging a sophisticated reverse genetics system and a suite of engineered reporter viruses, the researchers mapped the virus’s infectivity from the nose to the lungs—revealing an infection gradient that could hold the key to understanding COVID-19’s spread and severity.
