Covid-19 was first recognized in China in December 2019. Corona viruses cause mild to severe respiratory infections in humans. Different wavelengths disable viruses in different ways. In low-level laser therapy, visible light and infrared laser rays in the range of 450 to 1000 nm are used.In this study, we have studied the effect of laser light on the treatment of Covid-19. We have been looking for researches related to the subject from ScienceDirect, Google Scholar, ISI, Scopus, etc. scientific databases. In this article, the topics and results of 38 articles related to the years 1877 to 2021 have been used; And most of them are from 2017 to 2021.The first scientific observations of the antimicrobial effects of light were made by Downes and Blunt. Among the methods that are effective in the treatment of covid-19, we can mention light modulation, ultraviolet rays, blue laser light, LEDs and photodynamic therapy for the treatment of people infected with covid-19.Recent researches in the field of light modulation in the treatment of covid-19 have shown that the anti-inflammatory effects of light modulation can speed up the recovery of damaged tissues. In this treatment method, patients are discharged earlier.
