Antimicrobial treatment via phototherapy on internal organs - Oh Really ?

[AYTU] What is the need?

Novel coronavirus 2019 (SARS-CoV-2) is a viral infection that replicates in the upper respiratory tract. Approximately 10-15% of those infected with coronavirus disease (COVID-19) have a severe clinical course, with nearly 5% becoming critically ill requiring mechanical ventilation due to respiratory failure. Death resulting from COVID-19 is thought to be due to respiratory failure and/or secondary infections including ventilator associated pneumonia.

To date, there is no known treatment for COVID-19 or conventional means to reduce secondary infections in mechanically ventilated patients. Any safe and effective antiviral and antibacterial treatment option for these patients that could lower viral load and improve factors of respiratory failure would be advantageous.

ULTRAVIOLET (UV) LIGHT
Ultraviolet (UV) is a type of electromagnetic radiation with wavelengths from 10 nm to 400 nm. These wavelengths are shorter than that of visible light. Between the wavelengths 100 to 400 nm ultraviolet radiation (UV light) is subcategorized into three different ranges: Ultraviolet C (UVC) 100 — 280 nm, Ultraviolet B (UVB) 280 — 315 nm, and Ultraviolet A (UVA) 315 — 400 nm.

#6 Local barber always placed his combs and scissors under a U.V. light in a sani unit. That was 60 years ago.

#5 UV light has been used for years in ortho ORs.

As well as post-op OR cleanup.
When the scrubbing and mopping is done, give it a UV soak.

#4 UV light has been used for years in ortho ORs. Targeting surgical site infection (almost exclusively bacterial), is a proven technique aka settled science.

#2 No but close.
X-rays make up X-radiation, a form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 0.1 to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 200 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays.

Ultraviolet (UV) is electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.

#1 Back to back chest x-rays? Ouch.
