The inhibitory and inactivating effects of visible light on SARS-CoV-2: A narrative update
Prior to the coronavirus disease-19 (COVID-19) pandemic, the germicidal effects of visible light (λ = 400 – 700 nm) were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light – particularly blue wavelengths (λ = 400 – 500 nm)...

Sumario: | Prior to the coronavirus disease-19 (COVID-19) pandemic, the germicidal effects of visible light (λ = 400 – 700 nm) were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light – particularly blue wavelengths (λ = 400 – 500 nm) – on exposed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virions, and inhibitory effects on viral replication in infected cells. These findings complement emerging evidence that there may be clinical benefits of orally administered blue light for limiting the severity of COVID-19. Possible mechanisms of action of blue light (e.g., regulation of reactive oxygen species) and important mediators (e.g., melatonin) are discussed. |
