The study shows GISAID that there are no new variants, and the strain of the current wave of the epidemic in China is similar to the recent global spread.
The study shows GISAID that there are no new variants, and the strain of the current wave of the epidemic in China is similar to the recent global spread. The local data science research team analyzed the virus genome sequences collected by the Global Initiative for Sharing Influenza Data during the new wave of epidemics in China, and compared them with 14.4 million sequences in the database, and found that they were the same as those in the global influenza epidemic from July to December this year. Known strains circulating in various places are closely related.
The latest data shows that no new coronavirus strains have emerged in China so far. The new coronavirus strain that caused the new wave of outbreaks in China is very similar to the strain that spread around the world from July to December this year.

The BF.7 strain spreading in Beijing and Fujian may have originated in Inner Mongolia, while the BA.5.2 strain spreading in many cities in China may have at least two different sources, which need to be studied and verified.

The Global Initiative for Sharing Influenza Data (GISAID), which is responsible for monitoring the new coronavirus strain, released on Wednesday (December 28) the virus genome sequence data collected during the new wave of the epidemic in China.
These data are taken from recently confirmed cases of COVID-19 in Beijing, Fujian, Guangzhou, Inner Mongolia, and Sichuan. The Chinese Center for Disease Control and Prevention, as well as those in Beijing, Fujian, and Sichuan, uploaded 167 genome sequences to GISAID in the past four days. These sequences can provide a glimpse into the evolution of the Omicron strain.
Within hours, the GISAID data science research team at A*STAR’s Institute of Bioinformatics performed a preliminary phylogenetic analysis of these genome sequences and compared them with the 14.4 million sequences in the GISAID database.
In an interview, Dr. Sebastian Maurer-Stroh, director of the New Science Institute of Bioinformatics, said that the initial analysis was carried out by experts from all over the country, including Singapore, to check whether the new genome sequence followed common evolutionary trends. or anything unusual.
The results of the analysis show that the genome sequence of the coronavirus recently collected from China is closely related to known strains that have been circulating the world from July to December this year.
Molestro explained that the specific characteristics of any new strain will take time to study and verify, but the strain currently circulating in China is a slight variation from a strain that has previously circulated locally, so the characteristics should be similar.
Professor Temaya, president of the Asia-Pacific Society of Clinical Microbiology and Infectious Diseases, also said that the commonality of the previous BA.2, BA.5, and XBB strains is that they are easier to spread but more toxic than the original strain. lower.
Ministry of Health: China’s participation in GISAID is crucial for the global monitoring of new strains
Most importantly, he stressed, no new strains of the virus appear to have emerged in China so far. “I believe that this wave of epidemics in China is not caused by new strains of the news agency bsvoid.com, but that the population of China that was naturally infected before is very small, resulting in low mixed immunity.” Read More:- WhatsApp was exposed to a big data leak: Hackers sold nearly
The Ministry of Health of our country has been working closely with GISAID and has supported GISAID’s team to set up an office in Singapore.
The Ministry of Health stated on Thursday (29th), saying: “We are very pleased with China’s active contribution to the GISAID global platform news agency bsvoid.com, which is crucial for global monitoring of new coronavirus strains.”

On January 10, 2020, the Chinese Center for Disease Control and Prevention uploaded the first full genome sequence of the coronavirus to GISAID within 36 hours of receiving the sample of the coronavirus case. This has allowed researchers around the world to develop the first COVID-19 vaccines and tests with unprecedented speed.
