New coronavirus infection pneumonia attracts attention, UVC LED sterilization helps self-protection

2020-01-23 16:01:12 Clicks:

Recently, the outbreak of pneumonia caused by a new type of coronavirus in Wuhan has caused great concern in the society.

 

To this end, the National Emergency Response Office of the National Health and Medical Commission released information on Wuhan pneumonia. "Experts have concluded that the current epidemic situation is still preventable and controllable. However, the source of new coronavirus infections has not been found, the epidemic transmission route has not been fully grasped, and virus mutations still need Strict monitoring. In the next step, our committee will strengthen the coordination and coordination of departments and strictly implement epidemic prevention measures. We will continue to do a good job in preventing and controlling the epidemic nationwide to detect and effectively deal with the epidemic in a timely manner. "

 

Medical experts point out that Wuhan's new coronavirus is relatively mild, and its infectiousness and lethality are far less than SARS virus. It belongs to the preventable and controllable range, and there are already cured cases that prove that this virus infection can be treated with pneumonia. At the same time, Wuhan and other provinces and cities are gradually starting to detect the virus.

 

How to protect yourself? The World Health Organization recommends maintaining basic hand and respiratory hygiene, maintaining safe eating habits, and avoiding as much contact with anyone as possible showing symptoms of respiratory disease such as coughing and sneezing.

 

Therefore, in addition to passive protection technologies such as masks, active sterilization is also more used in disease prevention. When it comes to sterilization, I believe everyone is not unfamiliar with UV LEDs. UV LEDs refer to LEDs with an emission wavelength below 400nm, which can be further divided into UVA (320-400nm), UVB (280-320nm), and UVC (200-280nm) . The main application of UVC is sterilization.

 

According to TrendForce LED Research (LEDinside) 's "2019 Deep UV LED Application Market Report-Sterilization, Purification and Water Treatment Market", the global UV LED market size reached USD 299 million in 2018 and is expected to reach 991 million by 2023 US dollars, with a compound growth rate of 27% in 2018-2023. Looking forward to the application market demand, in addition to the stable growth of the curing market, surface / air sterilization and purification, stationary water sterilization, and flowing water sterilization will be the main growth momentum in the future.

 

Why can ultraviolet light kill bacteria? Studies have shown that ultraviolet rays mainly kill microorganisms through radiation damage to microorganisms (pathogens such as bacteria, viruses, spores, etc.) and damage to nucleic acids, thereby achieving the purpose of disinfection. The effect of ultraviolet rays on nucleic acids can cause bond and chain breaks, interstrand cross-linking, and formation of photochemical products, etc., thereby changing the biological activity of DNA and preventing microorganisms from replicating themselves.

 

Because children's immunity is low, they are more likely to be infected with pathogens and viruses, which can cause diseases. Therefore, children must be sterilized and disinfected. We take children's UV sterilization masks as an example. By using UVC LED, it can play a good role in sterilization.
