On January 4, the Chinese Center for Disease Control and Prevention revealed that from October to December last year, China had discovered 199 imported XBB cases through genome sequencing, including 9 sub-branches, of which 4 were imported cases of XBB.1.5; a total of 16 local XBB cases were reported, all of which were XBB.1 evolutionary branches, mainly concentrated from October to November, with only 1 case in December. No local cases of XBB.1.5 have been monitored so far. At present, the strains prevalent in my country are still dominated by BA.5 sub-branches BA.5.2 and BF.7. The Chinese Center for Disease Control and Prevention stated that the neutralizing antibodies produced by individuals after infection with BA.5.2 or BF.7 will maintain a relatively high level in the short term (3 months), and are expected to have good cross-protection against other Omicron variant branches (including XBB). In the short term (3 months) in my country, the possibility of a large-scale epidemic caused by XBB series variants including XBB.1.5 is extremely low. 01 Do you need to stock up on diapers if you are infected with XBB1.5? Expert: No need! On January 3, some netizens said that cases of XBB1.5 had appeared in Shanghai. Because people would suffer from diarrhea unconsciously after being infected, they called on everyone to stock up on diapers. In this regard, Professor Fang Bangjiang, director of the fifth ward of the third infectious department of Wuhan Leishenshan Hospital, leader of the TCM expert group of the Shanghai New International Expo Center Fangcang Hospital, and director of the Institute of Critical Care Medicine of Shanghai University of Traditional Chinese Medicine, said that the Omicron BQ.1 and XBB strains found in Shanghai have only been detected in a very small number of inbound quarantined personnel and have not yet caused local transmission in society. According to the latest data from the U.S. Centers for Disease Control and Prevention (CDC), in the last week of 2022, XBB.1.5 accounted for 40.5% of the new crown cases in the United States, almost doubling from 21.7% in the previous week, but there were no reports of high mortality rates. "The main clinical symptoms of XBB.1.5 include dyspnea, headache, sore throat, nasal congestion, body pain, fatigue and fever, which are almost the same as the symptoms of BF.7, which is currently popular in China. There are many symptomatic antidiarrheal drugs for possible diarrhea symptoms, including Chinese herbal decoctions and patent Chinese medicines with dampness-removing and antidiarrheal effects, such as Huoxiang Zhengqi Water, Tongxiening Granules, etc. In addition to the antidiarrheal effect, they also have the effects of strengthening the spleen and stomach." Professor Fang Bangjiang said, "In fact, common clinical 'viral colds' can also cause nausea, vomiting, diarrhea and other 'gastrointestinal cold' symptoms. This is a normal pathological reflection. Don't panic and don't worry about it." Professor Fang Bangjiang reminded that not only is there no need to stockpile diapers, but there is no need to blindly stockpile some antidiarrheal drugs such as montmorillonite powder. 02 More news about XBB.1.5 One picture to understand!
