Light as a Cure in COVID-19: A Challenge for Medicine

Light and lasers, as high-tech devices whose medical potential has yet to be fully discovered, have made important contributions medicine, even in the current pandemic. The main aim of this review was investigate how light applied a therapeutic tool during crisis triggered by COVID-19. Another goal encourage scientists industry quickly design new at-home photobiomodulation therapy (PBMT) and/or antimicrobial photodynamic (aPDT) easy use systems end pandemic, especially for those who believe but would never get vaccinated. This revealed that PBMT been successfully adjunct therapy, combination with conventional treatment, pioneering action SARS-CoV-2 infection, demonstrating significant improvements airway inflammation general clinical condition patients, faster recovery, avoiding intensive care unit (ICU) hospitalization, mechanical ventilation, mortality, overcoming long-term sequelae. Application only limited number cases strongly suggests need future randomized, placebo-controlled trials objectively determine effects Implementation unparalleled theragnostics methods light-based techniques disinfection spaces, air, skin, mucosae, textures decrease load virus save lives, time, money. In ongoing challenging search seemingly intangible non-invasive, easily accessible, safe, side-effect-free adjuvant method appears PBMT, alone or synergistic aPDT, which shown work COVID-19 opens unprecedented home self-treatment
