The Omicron virus is highly insidious and spreads quickly, and nucleic acid testing is a race

Since January 8, as of 12:00 on January 11, in just a few days, the cumulative number of positive infected people in the Omiljung epidemic in Tianjin and Anyang, Henan Province, has exceeded 180 cases, which is the first time that the mutant strain has spread in China's native communities.

On November 11, at the press conference on epidemic prevention and control in Tianjin, Zhang Boli, an academician of the Chinese Academy of Engineering, said that unlike in the past, the symptoms of the infected people in this round of the epidemic were relatively mild, resulting in strong virus invisibility, and those who did not have symptoms did not go to seek medical treatment, many of which were also found in the big screening, and the spread of the virus was very strong, and the situation that one person passed on more than a dozen people also appeared.

On the evening of January 10, Zhang Ying, deputy director of the Tianjin Municipal Center for Disease Control and Prevention, said in an interview that in the process of investigation, due to the occultity and rapid spread of the Omicron virus, once there is a missing situation, it is possible that when you find it again, the close contact has become an infected person, and a generation or two of transmission has begun in the community, so whether it is from the traceability, epidemiological investigation, or control, the virus has brought unprecedented challenges.

The first financial reporter from Jinyu Medical (603882. SH) learned that on January 10, the company also built the "Falcon" dura film laboratory in Tianjin and Anyang, and participated in the nucleic acid testing of all employees in the local city through the central laboratory.

Ren Jiankang, vice president of Jinyu Medicine and laboratory medicine expert, said that from the perspective of laboratory testing, the current mainstream detection methods can still detect the Omilon strain, "fast" is still the first meaning of nucleic acid testing, expand nucleic acid testing capacity, shorten the reporting time, so as to find the infected person quickly enough, find the transmission chain, in order to effectively prevent the spread of the virus.

In the case of strong occult and rapid transmission of the Omilon virus, there are also concerns about whether the sensitivity of existing nucleic acid detection reagents will be challenged.

Jin Dongyan, a professor at the School of Biomedical Sciences of the University of Hong Kong and an expert in virology, said in an interview with the first financial reporter that compared with the Delta virus, the Omilton virus is relatively highly contagious, but it also has its own characteristics, that is, the amount of virus is very low, it comes and goes quickly, that is, negative to positive, and then negative, it is easy to pass, easy to lead to missed tests.

People engaged in the research and development of nucleic acid detection reagents also told the first financial reporter that the virus load is low, mild or asymptomatic, it is easy to cause occult transmission, nucleic acid testing is a major challenge, easy to miss the detection situation, can be strengthened intervening quality assessment, improve the detection level of institutions and so on to improve the sensitivity of nucleic acid detection.

And Shengxiang Biological Respiratory Production Line Research and Development Project Director Tan Deyong told the first financial reporter that the current Omikejong virus seems to be symptoms may be relatively mild, still depends on everyone's body immunity situation, if the immunity difference or even the underlying disease may not be light, as far as the current feedback from the front line, the viral load of Aomi Kerong is not low, the fast spread and viral load and detoxification have a certain correlation, such as Delta's load is also very high, the speed of transmission is also very fast. The sensitivity of a nucleic acid detection kit depends on many factors, such as kit performance, extraction reagent, sample preservation solution type, sample type, and so on.

"The detection sensitivity of each kit may be different, our new crown nucleic acid detection kit is mainly based on the high-precision magnetic bead method technology developed by the company for many years, which can achieve high sensitivity or even ultrasensitivity detection of viruses, such as ultra-high sensitivity detection of 10 copies/ml." Tan Deyong said.
