A question some have asked, can ultraviolet light be used to kill the flu virus? Scientists have found a powerful new antiseptic that works to relieve the virus. Researchers say a certain spectrum of ultraviolet rays, known as long-range ultraviolet rays, in the atmosphere they pose no danger to them. humans.
A team at the Columbia University Medical Center in New York City said that it could offer a new, inexpensive way to eliminate influenza viruses in closed public places such as hospitals, doctors' offices and hospitals. doctors, schools, airports and airplanes. The study's principal investigator, David Brenner, said that the success of the preliminary tests remains to be confirmed, but he believes that the use of light in public places is a safe and effective way to reduce the transmission and spread of airborne bacterial diseases such as influenza and tuberculosis.
As the researchers explained, UVC light kills viruses and bacteria present in the atmosphere and is currently used to decontaminate surgical equipment, but this type of light can cause cancer of the skin. skin and cataracts.
Previous Studies
In previous studies, they found that ultraviolet light destroyed bacteria and Methylation-resistant Staphylococcus aureus without harming human skin. According to Brenner, who heads the Columbia Radiation Research Center, far ultraviolet light had a very limited area and could not penetrate the outer cell layer of human skin or the thalamus layer of the eye. The health of the man. Since viruses and bacteria are much smaller than human cells, remote UVC light can access and kill their DNA, he says in a press release published at Brenner University, indicating that the lamps in this type of ultraviolet radiation currently cost less than one thousand dollars. This price is likely to decrease if the bulbs are produced in large quantities.
The Scientific Perspective
The possibility of reducing the transmission of influenza and other respiratory viruses by far ultraviolet rays is very exciting, said Dr. Michael Grosso, Chief Medical Officer at the Huntington Hospital in New York. Grosso said that even though handwashing is still very important, it does not prevent the transmission of viruses. Vaccination and antiviral drugs are also important, and ultraviolet light seems to be safe and effective, and has Advantage of disrupting a wide range of pathogenic viruses
Dr. Lynn Horowitz, Pulmonary Specialist at Lenox Hill Hospital in New York City, agreed that the cost of UV technology is not prohibitive and that it is not expensive. It is safe, which can sterilize the air in many public places and reduce the spread that contains influenza viruses and other bacteria and viruses.
