In January, Leondios Kostrikis, a professor of biological sciences at the University of Cyprus, claimed that a suspected recombinant new crown strain of Delta and Omicron had been discovered by local researchers and named "Deltacron ".
It is reported that 25 cases of this virus with rapid nucleic acid detection of neo-crown, 11 from hospitalized patients with neo-crown pneumonia and 14 from the general public have been identified. Subsequently, Dr. Tom Peacock, an epidemiologist at Imperial College, and a WHO expert on NCC pneumonia concluded that the situation was more likely to be the result of "contamination".
Subsequently, the UK Health and Safety Executive's weekly strain surveillance report revealed that "Deltacron" had actually appeared in the UK, and said that the mutant strain was currently being monitored. In its weekly surveillance report, it states that it is unclear how contagious or severe "deltaquejon" is, or whether it affects the effectiveness of the vaccine. It is also unclear whether the observed cases originated in the U.K. or from overseas.
Delta Kron is known to be a recombinant new crown strain of Delta and Omicron, which is genetically closer to the Delta strain but has 10 mutations unique to the Omicron strain.
The existence of the Delta Kron strain is still open to debate and its related characteristics are still to be studied.
First of all, we should respond positively to all the precautionary measures and always have a four-piece set of precautionary measures: diligent ventilation, wearing a mask, washing hands, and a meter line. Do a good job of personal protection and guard the first line of defense for personal health.
Second, be aware of the dynamics of the epidemic around the world in real time, and travel plans should be changed in real time according to the epidemic situation around the world, and less than medium to high risk areas.
In general, it is important to receive a booster vaccination 6 months after the vaccination to maintain a high level of antibodies in the body.
Finally, a rapid nucleic acid test for new crown should be done. The whole process: sampling - sample pre-treatment - nucleic acid extraction or purification - PCR amplification and analysis, the whole process is a very rigorous and accurate experiment, which can accurately identify the virus by virtue of its core genetic material, so the rapid nucleic acid test is the "gold standard" for the diagnosis of new crown patients in the epidemic prevention and control.
In the past two years of the epidemic, there have been many epidemics throughout the country, and improving the efficacy of rapid nucleic acid testing has become an important requirement for major providers of rapid nucleic acid testing services. The rapid nucleic acid test, which tends to be an immediate test for POCT, was also born. The use of efficient amplification reagents, portable small-throughput amplification instrument to shorten amplification time and improve detection efficiency has become an important way.
