The worldwide outbreak of COVID-19 has people searching for anything that might protect them from it. There is demand for certain things and supply is quickly followed by people who offer dubious supplements or tools to help ward off the coronaviruses. UV sanitizing wands are popular because they promise to destroy germs.
They say sunlight is the best sterior, but should you stick to soap and water or use a UV wand? Kim was the executive vice president of medical device services at the organization. The FDA Quality Systems Regulations for medical devices were written by Trautman.
What does UV light do?
Ultra violet light is a type of radiation. The UV-C wavelength is capable of damaging viruses andbacteria by disrupting their DNA/RNA, rendering them unable to replicate, and it is one particular type. Hospitals are using large UV lamps to sterilizerooms uvc sanitizer wandin response to the COVID-19 outbreak.
The problems with UV light as a disinfectant
It is probably good enough for your home if it is good enough for hospitals. Not quite. There are a number of problems with using a UV wand. UV-C radiation won’t be helpful unless you live in a bare room
The effectiveness of UV-C light is on more flat surfaces according to most of the science. It doesn’t work in nooks and crevices because it’s a spectrum of visible light and if the light can’t get in, it’s not going to have the same effect. If you have crooks and crannies, those germs won’t be affected by the UV-C light.
If you were to try and suck out all the germs in a room, you would probably be stuck with it for a while.
If you see a picture of some of the hospital units that have been used for this purpose, they are very large. They are not just a handheld wand. You have to have something that is in the right place in the room to be able to radiate. If it doesn’t radiate, then the entire room will have to be treated with a mechanism that rotates.
A hazard to your health
The UV wand can’t be used to destroy human flesh because of the dangers of UV-C light.
She says that UV-C light can cause cancer and degrade cell walls, and that it can also cause cancer in humans. The spectrum of UV light gives us sunburns. Exposure to human skin, to the eyes, and so forth can be very harmful. It is not something to be lightly done.
There are no people in the hospital rooms. UV wand requires someone to hold it. While looking through some of the UV wands on Amazon, none seem to include protective equipment, although one did specify that customers should wear protective glasses while using it. The device can hurt you if it is capable of destroying viruses.
If you are waving it around and there is no way to protect you, you are probably doing more harm to yourself than the potential of what you are disinfecting, says Trautman.
The science on coronaviruses is not there yet.
UV radiation is a problem because we don’t know how effective it is at killing COVID-19. The duration of direct exposure is important when using UV radiation. It is more than a flash of the light. It has to have a specific time period in which it can have direct UV-C light.
The exact duration needed for a light source can be different for a virus, and all viruses are not equal. There is no scientific consensus on how strong the coronaviruses is, and some are more susceptible to UV radiation.
It is more robust than some of the earlier coronaviruses, according to Trautman. The earlier varieties of the disease died quicker on the surface. COVID-19 is lasting longer on some of the surfaces than it has on others, and we already know this. There is no specific scientific study that can say what the time and duration of UV-C exposure would be needed to prove that COVID-19 has been disassembled.
When in doubt, trust the health authorities
Many of the UV gadgets on the internet go to market without the approval of health authorities.
The FDA doesn’t get involved if UV lights are being used for things that don’t have medical claims. I have seen a lot of these containers that they say to put your cell phones in. The FDA is not involved in those types of claims.
The cons of UV light are outweighing its usefulness, for example, you can’t know how long you need to kill coronaviruses, and you may end up hurting yourself in the process.
What should you do if you are worried about coronaviruses on your countertops? The CDC has guidelines for people to use to make sure they are free of disease.
The science is not there and anything else is speculation.
The World Health Organization has a page about the novel coronaviruses outbreak.
