Photodynamic Therapy as a New Technology for Inactivation of Coronavirus Disease (COVID-19)

Coronavirus Disease (COVID-19) could be an emerging disease with a severe acute respiratory infection, and its epidemiology and unique medicinal properties are perpetually increasing. Regarding the lack of COVID-19 controls, this needs current technical events to worsen and treat. Antiviral Photodynamic Therapy (aPDT) could also be effective in reducing and inhibiting the coronavirus. aPDT with various photosensitizers is a very favorable procedure to manage viral infections.

A total of 37 articles related to the publication of this review manuscript were mentioned. Several scientific databases such as Scopus, PubMed, Web of Science (ISI), and Google Scholar have checked the key phrases of COVID-19, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), photodynamic therapy, and antiviral photodynamic therapy. All 50 main studies were found, and 37 related studies were deemed suitable for this study after review.

Studies have shown that aPDT with different photosensitizers can be used to treat viral lung complications caused by infectious pathogens such as Middle East Respiratory Syndrome (MERS), SARS-CoV-2, and influenza. Recent studies have shown that aPDT-mediated Methylene Blue (MB) can help control and eradicate coronavirus. In general, more research is needed to use antiviral photodynamic therapy to control COVID-19.

Regarding the lack of treatment for COVID-19, MB-mediated aPDT can help reduce the impact of COVID-19. More evidence is needed to support aPDT as a treatment (SARS-CoV-2).
