COVID-19 (Coronavirus Disease 2019) is a disease caused by the new coronavirus SARS-CoV-2, which is the cause of the virus outbreak that caused a massively devastating pandemic. Public health systems and economies around the world have been damaged by the virus. Many people ask this question: “Can ultraviolet rays kill Covid?”. The answer is yes, use the right type of UVC Light under the right conditions.
Let’s dive right in now, and you can click on the question that interest you,
1 Types of UVC lights that can effectively kill Covid
Ultraviolet (UV) is a type of ultraviolet radiation from the sun that has less energy than X-rays and gamma rays, although it has more energy than visible light and radio waves. Sunlight emits natural ultraviolet rays in three major spectrums, namely UVA, UVB, and UVC. Although most natural UVC rays are absorbed by the ozone layer, people may still be exposed to UVA and UVB rays from natural sunlight.
UVC light replicates in man-made germicidal UVC lamps and has been proven to kill many viruses and bacteria, including β-coronavirus. SARS-CoV-2 belongs to the beta coronavirus family, similar to MERS (Middle East Respiratory Syndrome) and SARS (Severe Acute Respiratory Syndrome). Facts have proved that UVC lamps can effectively eliminate MERS and SARS. Recent studies have shown that UVC lamps are equally effective in killing the SARS-CoV-2 virus that causes COVID-19.
2 Will ultraviolet light kill Covid in liquids?
Ultraviolet light is an effective disinfectant and disinfectant and has been proven to kill viruses in water, surfaces, and air. UVC light effectively inactivates bacteria and viruses by destroying cell nucleic acid, making it impossible to replicate. Inactivated cells that cannot replicate are considered harmless and cannot spread other diseases. According to a new study in the American Journal of Infection Control (AJIC), UVC light has been proven effective in killing the SARS-CoV-2 virus that causes COVID-19 in liquid culture. UVC lamps are used in UV water disinfection applications, such as wastewater treatment plants, aquaculture, swimming pools, and spas, and much other water disinfection needs.
3 Will ultraviolet light kill Covid on the surface?
It has also been proved that the UVC germicidal lamp is very effective in killing the surface SARS-CoV-2. Other studies by AJIC have shown that the effective rate on the laboratory surface is 99.7%. In order to achieve high efficiency in disinfecting surfaces, they must be cleaned and exposed directly. Therefore, many hospitals and medical institutions have installed UVC robots and UVC lamps in their strategic air and surface disinfection systems to add UVC light disinfection to their regular cleaning programs.
Manufacturing UVC lamps that emit light in the UVC range is the most effective way to kill viruses and bacteria, while standard germicidal lamps are designed to emit light at 254 nm. Although this wavelength has been proven to be very effective, it may also cause damage to human skin and eyes. Therefore, some germicidal lamps are designed to emit a wavelength between 207-222 nm, called far-ultraviolet light, which is the basis of this study. Focus. Far ultraviolet lamps can still effectively kill bacteria and viruses and are less harmful to skin and eyes than other types of ultraviolet lamps.
4 Will ultraviolet light kill Covid in the air?
Many scientists believe that airborne particles are one of the most common ways of spreading the SARS-CoV-2 virus. Therefore, sterilizing and disinfecting the air in an enclosed space should help protect people from Covid disease. The UVC lamp in the HVAC unit is an effective method of disinfecting the air and has been used in many commercial, industrial, and residential air purification systems. The latest research published in Scientific Reports concluded that UVC light can effectively kill coronaviruses in the human body, including human coronaviruses that cause the common cold and SARS-CoV-2 viruses.
According to our understanding of ultraviolet rays, especially the ultraviolet rays emitted in the UVC range, it can be said with certainty that ultraviolet rays can be used to kill the SARS-CoV-2 virus, which will produce COVID-19 on liquids, surfaces, and in the body. air. The far-ultraviolet lamp may be a good choice for certain disinfection applications because it is less harmful to human health.
