(Rome / Washington Composite Electric) Italian official confirmed that only the Omikon virus was found in the positive samples of all crown diseases in China recently, and there were no new variety of strains.This alleviates people's concerns about new poison strains.
Earlier reports have reported that half of the two flights from China to Milan recently, half of the passengers' crown detection results are positive, causing concerns that there will be new poison strains.
The Italian Minister of Health Squesratic said in a TV interview on Friday (December 30): "We are relieved, because all cases of all cases appearing in Italy have been checked."
He revealed that about 10%to 20%of passengers' crown disease testing in various flights where Roman airports landed.
The United States says that the outbreak of the crown disease will have no clear impact on the trend of the epidemic.Nordron, a spokesman for the American Centers for Disease Control and Prevention (CDC), said: "China's population has not yet formed collective immunity to crown disease, so virus variation may still occur."
However, Gisaid, a global shared influenza data initiative (Gisaid) that tracks the mutation of coronal virus, said that the information in China recently notified is reassuring.
In the past week, Gisaid has collected nearly 1,000 gene sequences from all over China.The founder of the organization, Pogner, said: "Virus is still continuing to spread, but there is no major mutation that can attract special attention."
Data Analysis Company Airfinity said that according to the published limited gene sequence information, the crown disease strains currently disseminated in China are basically the same as that elsewhere in the world.
Scientists: If it is infected with Omikon, it must be detected for a longer time
Nevertheless, some experts believe that new variations worthy of attention may be only a matter of time, and because the information sharing is limited, it is difficult to prepare.
Wilbur Lam, the National Institute of Health, said: "China's epidemic makes us very concerned." He believes that the United States requires passengers from China to show a 48 -hour test before taking off.Everything is lost.
Viruses like coronary disease may occur at each copy, but these mutations are sometimes insignificant and can even prevent the virus from growing.Only in rare cases, new mutations can promote a certain mutant strain quickly.
For example, the XBB of Omikon subtypes in northeast of the United States has led to at least one local detector in the local area has become unreliable.Scientists have found that overall, if Omikon is infected, it must be detected for a longer period of time.
Ska Pino, director of the Department of Artificial Intelligence and Life Sciences of Northeast University, said that if China lacks effective epidemic prevention measures to prevent viruses from spreading in the country, new mutations may soon cause problems.He said: "In the next one or two months, we will pay close attention to this."
