Highly infectious variant of covid-19 virus: Omicron mutant virus is sweeping the world. Omicron also began to appear in the capital Beijing last weekend.
On January 15, Beijing reported a new confirmed case of local covid-19 pneumonia, which was positive for the Omicron variant. On the 17th, Beijing held a press conference on epidemic prevention and control. At the meeting, it was reported that the patient had recently received and sent international emails. The international mail was sent from Canada on January 7 and arrived in Beijing through the United States and Hong Kong, China. According to the press conference, the 22 environmental samples of the international mail, including 2 outer surface, 2 inner surface and 8 paper samples in the document, were positive by nucleic acid detection, and the specific mutation sites of Omicron mutant were detected.
Up to now, there are 8 people who may be in contact during transportation. Except for diseases, the nucleic acid test results of other contacts are negative. In addition, 54 unsealed environmental samples of international mail sent from the same source to another place were collected, and 5 were positive, including 1 positive outer package and 4 positive paper in the document. To sum up, does not rule out the possibility of virus infection through overseas articles in combination with the epidemiological history of the case, the detection results of suspicious article samples and the gene sequencing results of case samples.
In the period when covid-19 epidemic began to rage, virus infection through goods has entered people's vision. At the epidemic prevention and control conference held in Zhuhai on January 17, also mentioned that early cases often contact overseas inbound goods . Local experts also believe that contaminated inbound goods are likely to transmit viruses.
Since 2020, salmon, pitaya, imported cherizi and other foods have been transported by the cold chain, and covid-19 virus has been detected in the outer packaging, which has led to a sharp drop in prices and other events. Over the past two years, the corresponding covid-19 killing technology has also tended to be complete.
The agency said that in the long run, the routine trend of covid-19 epidemic increases people's demand for daily virus killing . UVC killing equipment will replace traditional sterilization methods in the future and promote the large-scale use of UVLED killing equipment.
Some concept stocks involved in covid-19 virus killing in the combing business of financial associated press are as follows :
Shenzhen Leaguer Co.Ltd(002243) : liheyunji, a holding subsidiary, has developed self killing and anti-virus functional materials. By coating self killing and anti-virus functional materials on the surface of objects, it can effectively kill viruses and bacteria to achieve the effect of protection and self killing.
Hangzhou Zhongya Machinery Co.Ltd(300512) :20 July, the company said sterilization Siasun Robot&Automation Co.Ltd(300024) for killing SARS virus, MRSA coronavirus, Ebola virus and New Coronavirus and other remarkable results.
Mls Co.Ltd(002745) : the second disaster activity rate of UVC deep ultraviolet surface killing series products to coronavirus is 99.994%.
Xiamen Guang Pu Electronics Co.Ltd(300632) : the UV disinfection products provided by the company for customers have passed the German VDE test and can kill 90% of covid-19 virus within the specified range.
Cgn Nuclear Technology Development Co.Ltd(000881) : compared with ultraviolet disinfection, the irradiation sterilization of the company's electron accelerator has the advantages of stronger penetration, more types of irradiated products and higher efficiency; In December of 20 years, the experiment of radiation killing covid-19 virus in the outer packaging of cold chain food was being carried out.
Csg Smart Science&Technology Co.Ltd(300222) : the unmanned killing Siasun Robot&Automation Co.Ltd(300024) developed by Huaxiao Precision Industry (Suzhou) Co., Ltd., a wholly-owned subsidiary of the company, takes AGV + as the concept and carries UV life-saving equipment through AGV to carry out autonomous mobile anti-virus on the surface of environmental objects and air.
