How UVC Kills Coronavirus

With speed Covid-19 spread out in the world and already killed millions of people, the anxiety and panic are also reaching its peak. Doctors from different countries and other people come with different remedies and techniques to combat this deadly virus. Some have proved to be myths, and others have helped patients to some extent. Until the vaccine comes out, there are going to be new cures every day. Among the thousands of health advice circulating on the internet, one such remedy to kill Coronavirus through Ultraviolet Light has caught the most attention of the world. In this blog, we will examine through facts and reason that Does UV light can really kill Coronavirus, or is it just a myth.

kill Coronavirus, or is it just a myth?
UV light is not a new technique; it has been in use for many years to kill bacteria. There are two currently used methods of Ultraviolet infection control, and one is through chemicals and the other through radiation to disinfect bacteria. Sun and specialized lamps are the sources of UV light. Cleaning water and disinfecting other items in sunlight is an old tradition to kill bacteria, so many people are of the view that sitting in the sun can kill the Coronavirus.

Types of UV rays:
Three types of ultraviolet radiation exist in sunlight: UVA, UVB, UVC. UVA is responsible for skin diseases and sensitivities like wrinkles and aging; UVB can destruct DNA in the skin, causing cancer. UVC radiation being the most dangerous of all the types is capable of destroying genetic material, including that of viruses, but they are filtered out through the ozone layer: hence UV is unable to destroy the life cycle of this virus through this natural method of UV exposure.

Is it safe or not?
The question arises about the safety and precautionary measures related to using ultraviolet radiation. According to the World Health Organization, skin diseases and skin cancer are associated with UV radiation, and hands should be disinfected using soap or sanitizers. But scientists have found UVC useful in sterilization, but how much it is successful in killing Covid-19is unclear because of its harmful effects. UV light is extremely dangerous for skin, causing irritation damaging the eyes, and doctors and health experts have given clear warnings against the use of this method of disinfection. The UV light can be effectively used on objects and places like stations, airports, or offices, but its exposure to skin is dangerous. That is why in some countries, buses are lit up by UVC lights, and floors are being disinfected through this same technique. Lamps, pouches and other products are available to sterilize mobile phones and other objects. The impossibility of using UV light also lies in the fact that bacteria can be killed using longer wavelengths of radiation, but this Coronavirus requires a high level of radiation, which is highly costly and not affordable for everyone. The researches have made the scientist believe that high-intensity UV light can only be emitted from strong and efficient UV LED, and scientists are still working to find a solution to this problem. The need is to ensure the safety of human lives by discovering UVC light that can kill the virus permanently without endangering human life. Nature has protected us from this radiation, so we should not expose ourselves by man-made radiation without precautionary measures. So the answer to the question asked above is yes, UV light can kill corona, but its safe form is still not available.

Busting a myth:
The myth that sunbathing is effective in killing this virus needs to be busted because the UV light type that is capable of destroying the genetic material of the virus and stop it from multiplying is filtered out by the ozone layer. Therefore sitting in the sun will only give sunburn or tan, not any cure of the corona. Scientists are working to discover such form UVC that can kill can Covid-19 while being safe for human skin. But the best way to stay away from this pandemic is to wash your hands, wear masks, and maintain social distancing.
