Recently, the new term "Delta Croon" began to appear in the public eye. Israel's Jerusalem Post quoted Cyprus media reports on January 9 that researchers at the University of Cyprus are suspected of discovering a recombinant new coronavirus strain of Delta and Omiljung, which is genetically closer to the Delta strain but has a large number of unique variants of the Omiljun strain. For this reason, the strain was named "Deltacron" by the researchers.

Does "Deltakron" really exist?
Mutations in laboratory and clinical viruses are of course discovered first by researchers and healthcare workers, but, first, such discoveries must be published in formal scientific journals; second, such findings should be cross-corroborated by multiple studies from different laboratories or clinical trials. Only on these bases is it possible to be identified by an authoritative body.
Judging by these criteria, "Deltakron" is only a hypothesis, even a guess. A comparison of the Attitude of the World Health Organization (WHO) towards Opmi kerong shows this. The new coronavirus variant, Aomi Kerong, was first reported in a formal paper and obtained multiple evidence from the laboratory. The researchers found that there were more than 30 mutant amino acids in Omilon, and were verified by multiple laboratories, so the WHO quickly identified this variant as a "variant of concern" (VOC) and named it Omiljung after careful consideration.
At present, the WHO has not recognized and published "Delta Kerong", indicating that "Delta Kerong" has yet to be confirmed. Moreover, at the end of December 2021, a number of Indian media also reported the emergence of a "Semikron + Delta" hybrid strain in the country, and also gave a name "Delmicron". These circumstances indicate that Delta and Aumechjong may be integrated and reorganized, but this is not confirmed at this stage.
The so-called "Delta Croon" has also been questioned by peers. Virologists at Imperial College London in the United Kingdom posted on social platforms that the widely reported "Delta Kejong" appears to be contaminated with test samples, or patients are infected with both viruses.
However, the Laboratory of Biotechnology and Molecular Virology of the University of Cyprus has uploaded the genome of what they consider to be the "Deltakron" variant strain to the GISAID international database, so it is possible to confirm in the future whether it is a new variant, whether it is more pathogenic or contagious, and whether it will be a pandemic.

Now we must also be wary of the Opmikron pandemic
At present, the most important thing to pay attention to and worry about is The Omicron, because most of the pathogens of the new wave and mainstream epidemics in the world are the Omikeron variants. According to data from Johns Hopkins University in the United States, on January 3, 2022, the United States reported a record 1080211 cases, of which the Aumechjong mutation virus caused the majority.
On January 4, the United Kingdom reported 218724 new cases of COVID-19, mostly caused by Aumi kerong; also on January 4, France reported 271686 new cases of COVID-19, the highest number of single-day infections recorded in France since the outbreak, most of which were caused by Omilon. On 5 January, India reported 58,097 cases, the most infections in a single day since the outbreak, and all of them were triggered by the Omi kerong variant, with nearly a third of those infected coming from Delhi and Mumbai.
On January 8, Tianjin found two cases of positive nucleic acid tests for the new crown virus, all of which belonged to the Aomi Kerong variant. Moreover, on December 13, 2021, Tianjin detected that the imported cases were infected by the Aomi Kerong variant (B.1.1.529 evolutionary branch), which is the first city in China to find imported cases of Aomi Kerong.
These circumstances all show that the foreign countries are already the Opmi Kerong pandemic, and the domestic government should also be vigilant against the spread of Theomi Kerong. One of the characteristics of Omiljung infection is that children are susceptible to infection and may develop more severe symptoms. The reason is that countries around the world have fewer people under the age of 12 vaccinated than adults, and because there is no vaccine trial data for children, many countries only vaccinate children after adult vaccination is universal; another reason is that young children's nasal passages are relatively small, especially babies mainly use their noses to breathe. This makes post-COVID-19 symptoms worse in children than in adults.
Therefore, whether there will be "Deltakron" or other new variants, there can be no relaxation in the prevention and control of the new crown.
