The epidemic has really been on the rise again and again. China has just ushered in a large-scale unblocking. Everyone is still studying how to deal with the popular BA.5.2 and BF.7 strains in China. In Japan, a new mutant strain called "Hellhound" BQ1.1 has begun to spread in Japan. This strain has only 49 BQ.1 and branches found in 9 provinces in China and has not been widely popular.
Why is this strain named Hellhound such a bad name? In fact, the "Hellhound" strain was first discovered in Nigeria . Later, it began to spread in Europe and the United States, and recently came to Asia. The name of this new variant of Omicron comes from Germany. BQ.1 and BQ.1.1 are both named "Hellhound" or "Cerberus" , referring to in Greek mythology, the dog of Hades god
According to the mythical description, 新安全新安 新安 新安 新安 新安 新安 新安 新安 新安安 新安安 新安安 新安安安 新安安安 新安安安 新安安安 新安安安安 新安安安安 新安安安安 新安安安安安 新安安安安安安安 新安安安安安安安 This beast is often described as having a snake as its tail, which protrudes from various parts of its body.
According to German reports, the name of the new variant seems to appear on Twitter first. It is not official, but it is easier to remember variant type , Because it is difficult to remember the official name, various other variants have also been given unofficial names, including "Centaurus( Centaurus )" in BA.2.75.
In France, they already account for 25% of cases, Belgium accounts for 10% of new infections and 5% of new infections in Italy. According to Health Minister Carolina Darias, currently in Spain, they account for 2.7% of active infections, and it is expected that by December 12, it will become the main strain .
According to the description of the Centers for Disease Control and Prevention in the United States, BQ.1.1, the offspring of BQ.1, can avoid antibody immunity, resulting in ineffective monoclonal antibody treatment for people at high risk of COVID. A study by the Pioneer Innovation Center of Biomedical Innovation at Peking University in China last month showed that BQ.1.1 escaped immunity against Bebtelovimab and Evusheld, the last monoclonal antibody drug that is effective against all variants, and it works against certain variants. authors write that together with variants CA.1 and XBB, BQ.1.1 may cause more severe symptoms.
Currently there is not enough data to determine whether the Cerberus variant causes different or more serious or less severe symptoms than other currently popular variants.
Nevertheless, in many patients, the symptoms caused by persistent infection of this novel SARS-CoV-2 variant appear to be very similar to those of the common cold or flu. Among these symptoms, we found:
- nasal congestion;
- runny nose;
- low-grade or fever (under 38°C in many cases);
- 5 throat soreness ;
- 5 mild cough or dry cough.
Scientists worry that the number of mutations may cause the new vaccine and the antibodies that have been produced during the pandemic that have not been recognized by the virus in the latest evolutionary state.
It can be seen that although this Hellhound mutant strain has a better escape effect on the antibody, it causes little harm and has not increased its virility. No countries have reported severe cases of deaths in BQ.1 and branch BQ1.1 infections. They are mainly mild symptoms. There is no need to panic. It is the key to taking personal protection and getting a good vaccine.
