The Impress of Low Level lasers in the Treatment of Patients with in Virus COVID-19 (SARS-CoV-2)

Abstract

Introduction-Coronavirus disease 2019 (COVID-19) originated in the city of Wuhan, Hubei Province, Central China. COVID-19 is caused by a novel coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). At present, the newly identified SARS-CoV-2 has caused a large number of deaths with Millions person of confirmed cases worldwide, posing a serious threat to public health. However, there are no clinically approved vaccines or specific therapeutic drugs available for COVID-19(1). The evidence shows that blue 450 nm light is antimicrobial against numerous bacteria, and that it accounts for Niels Ryberg Finsen's Nobelwinning treatment of tuberculosis. Further evidence shows that blue light inactivates several viruses, including the common flu coronavirus, and that in experimental animals, red and near infrared light reduce respiratory disorders, similar to those complications associated with coronavirus infection. Moreover, in patients, red light has been shown to alleviate chronic obstructive lung disease and bronchial asthma(2). LLLT can be added to the conventional treatment in COVID-19 at different stages of the disease.
