The compound new coronavirus variant strain is killed, and it will trigger the next wave of global pandemic at any time. The "Deltacron" virus, which is composed of Delta and Omicorn, has caused heated discussions on the Internet earlier.
The British health department recently announced that three new circulating virus strains are synthesized from mutant viruses, including two viruses composed of Delta and Omicorn BA.1, and one composed of Omicron's own BA.1 and BA.2.

The three popular compound variant virus strains found in the United Kingdom are named XF, XE and XD respectively. XD and XF are mixed from Delta and Omicorn BA.1, commonly known as Deltacron virus. The gene of XD virus is mainly Delta, only A small part is BA.1.
In contrast, most of the genes in XF are BA.1.
At present, XD is mainly prevalent in France, and no cases have been found in the United Kingdom. There are 49 cases in the world. XF has recorded 38 cases in the United Kingdom.
However, no more cases have been found since the middle of last month, and it is believed that there is no community transmission.
As for XE, it is a recombination of two strains of Omicron, BA.1 and BA.2. Its viral genes account for a larger proportion of BA.2, which is currently circulating in Hong Kong. It began to circulate in mid-January this year, and 637 cases were temporarily recorded. .
The latest research also found that the transmission power of XE is 9.8% higher than that of BA.2 alone, and there have been signs of transmission in the English community recently.

Experts urge the government to do a good job of entry quarantine measures
The Faculty of Medicine of the University of Hong Kong also found another virus that was not XE but was also compounded by Omicron BA.1 and BA.2 in two Dutch passengers who were infected with the virus. The difference was that the XE gene was mainly from BA. 2. However, about two-thirds of the virus strains discovered by the University of Hong Kong came from BA.1, but the two infected people only had mild symptoms and no serious discomfort.
With the relaxation of entry restrictions in Hong Kong, the no-fly ban from nine countries has been lifted since yesterday. Nearly 2,000 passengers have arrived in Hong Kong in one day. Some experts are worried about the introduction of a new compound variant virus and call on the government to take good quarantine measures.
Xu Shuchang is worried about the increase in the number of fake people during Easter, and the epidemic may rebound. Next week, we will discuss the fourth injection to give priority to the elderly. The government continues to empower doctors to compulsorily test patients with the epidemic within 14 days from today. Negative about 2%
