Can UVC lamp kill the Coronavirus

  1. Broad-spectrum sterilization and disinfection of ultraviolet radiation:

Research have shown that ultraviolet radiation mainly kills microorganisms by radiating damage to microorganisms (bacteria, viruses, spores and other pathogens) and destroying the function of nucleic acids, so as to achieve the purpose of disinfection. The killing effect of ultraviolet radiation on bacteria and viruses is common in common bacteria and Virally verified, bacteria such as Mycobacterium tuberculosis (Mycobacterium), Vibrio cholerae, Pseudomonas spp, Salmonella spp, Enteric fever spp, Typhimurium, Shigella spp, Staphylococcus spp Genus, coliform bacteria, viruses such as influenza virus, poliovirus, rotavirus, tobacco leaf virus, hepatitis B virus, mold spores

  1.  Infection protection of new coronavirus

From the perspective of infectious diseases, the infection of the new coronavirus in 2019 is mainly transmitted through the respiratory tract droplets from the carrier of the pathogen to the susceptible population and infection [6]. From the perspective of transmission channels, the protection of the infection of 2019 new coronavirus is considered from the following three aspects:

  • Infection source angle: isolation.
  • Propagation route angle: physical protection or killing.
  • Perspective of susceptible people: improve immunity.

Wearing a mask and sterilizing the environment and objects with alcohol / disinfectant / UV radiation are all measures to cut off the transmission route. Among them, masks and other methods are partition protection, and methods such as alcohol wiping, spraying disinfectant and UV sterilization lamps are Ways to kill viruses. In terms of killing viruses, ultraviolet sterilization lamp disinfection is compared with alcohol wiping and spray disinfection lamp disinfection methods:

The same point: all belong to broad-spectrum sterilization and disinfection methods.

Differences: There are differences in usage and ease of operation.

  1.  Effectiveness of coronavirus and ultraviolet germicidal lamp

There are many types of coronaviruses, viruses that cause common colds, SARS virus (SARS-CoV) that caused 2003, and the new coronavirus (2019-nCoV) found this time are all coronaviruses, which are caused by different types of coronaviruses Strength and clinical manifestations are also different [7]. The 2019-nCoV found this time is the seventh coronavirus known to infect humans [8].

Viruses are sensitive to ultraviolet rays and heat [6]. As mentioned above, ultraviolet radiation is based on the broad-spectrum killing effect of viruses based on the destruction of nucleic acids. During the SARS period in 2003, studies have also shown that the killing effect of ultraviolet radiation on SARS corona virus in vitro is confirmed [ 9] Therefore, 2019 new coronavirus as a (corona) virus can theoretically be killed by ultraviolet radiation.

The dose of ultraviolet radiation that can kill viruses is related to the following factors:

The total amount of ultraviolet radiation depends on the radiation time and radiation intensity;

  • The in vitro environmental conditions the virus is in including the ambient temperature and humidity;
  • Virus and attachments in vitro and UV radiation penetration.

4.Warm warning :

While ultraviolet radiation kills bacteria and viruses, its radiation also harms human skin and eyes. Therefore, when installing and using ultraviolet radiation to ensure that its radiation dose can achieve sterilization and disinfection, it should also ensure that: in unmanned conditions Under use (avoid exposure to human body)

The ultraviolet radiation represented by the central wavelength of 253.7nm has a broad-spectrum killing effect on bacteria and viruses, and its effectiveness has been experimentally verified on the SARS virus. To kill 2019 new coronavirus, use UV sterilization lamp under unmanned conditions, its sterilization and disinfection effect can achieve the purpose of infection protection by destroying the transmission route

Air needs anti-virus. In this special period, our masks and phones need anti-virus, deep ultraviolet anti-virus at 275nm. It can effectively kill 99.9% of bacteria and viruses, and can be widely used for the disinfection of objects and rooms!
