Can UV light sanitize surfaces and kill Coronavirus?

Germicidal Lamp

Even though UV light technology is in race to sanitize surfaces and kill germs for decades. However, novel COVID-19 pandemic has breathed a new life into the decades’ old UV light sanitizing technique to kill germs in the air and surfaces. 

Hospitals are utilizing UV light to disinfect surgical suits and to cut down the drug-resistant superbugs’ spread. However, in regards to UV light coronavirus, a new interest of using this technology in spaces like office buildings, restaurants, and schools, etc. is being shown to help reduce coronavirus transmission, once the public spaces are going to reopen. 

Can UV light work against the SARS-COVID-2, the virus behind COVID-19?

Even though ultraviolet light has been known effective to stop pathogens in their track for years, does it work against coronavirus or not has become one of the most important concerns of people at present. The short answer is definitely yes, but it requires the right UV kind in the right dosage. 

How does UV light can sanitize air and surfaces?

As germicidal lamps with ultraviolet technology have been around for decades, they have had excellent success in removing germs from air and surfaces. However, now with coronavirus pandemic tons of people are reaching the germicidal lamp to ensure reduced transmission of coronavirus. However, at the same time people also want to know how this UV light technology works to sanitize air and surfaces in an effective way.

  • There are three different types of UV light being used in the devices to kill germs and coronavirus. Even though UVC does kill the coronavirus bit it has to be used adequately.
  • However, germicidal lamps can deactivate the DNA of viruses, bacteria and other pathogens, that will ruin their ability to grow and multiply in numbers as well as to cause diseases.
  • More particularly UVC light has the ability to cause damage to the microorganisms’ nucleic acid by producing a covalent bond between specific adjacent bases in the DNA.

The formation of these specific bonds will stop the DNA from being unzipped for the process of replication. Ultimately the virus, bacteria and other pathogens will be unable to reproduce whether in air or on surfaces. Even when the microorganisms are going to try to reproduce, these will die.

Most commonly, a germicidal lamp or UV light coronavirus lamp contains a low pressure and short-wave tube that will produce UV wavelength that is lethal to coronavirus.

UV light is surely a good solution:

UV light can kill coronavirus and can sanitize air and surfaces effectively. The wavelength of UV germicidal lamps is in the region of max germicidal effectiveness and is highly effective to kill viruses. As the air passes through the germicidal lamp front or the surface is going to be exposed to germicidal ultraviolet light, the genetic material of the virus will be deactivated.

Final thoughts:

Ultimately, it will be unable to reproduce anymore and even the light will render that harmless. Due to this, UV light technology can easily be considered as the best means to stop transmission of coronavirus.
