Speaking of the hot spots in these two days, antidiarrheal drugs such as XBB. 1.5 strain and montmorillonite powder are definitely indispensable. Bian Xiao's friends took a screenshot of their circle of friends and urged Bian Xiao to buy medicine quickly. With questions and curiosity, let's take a look at this XBB. 1.5 today. Is it really necessary to hoard antidiarrheal drugs?
What is XBB. 1.5?
On February 30th, 2022,65438 EDT+data released by the US Centers for Disease Control and Prevention showed that it was estimated that 40.5% of COVID-19 infection cases in the United States in that week were caused by the highly contagious Omicron subtype strain XBB. 1.5.
Pecots, a virologist at Johns Hopkins University in the United States, said that XBB. 1.5 has an additional mutation, which can better combine with cells. Scientists at Columbia University warned in a study that the increase in the number of XBB subtypes in Omicron may further weaken the efficacy of COVID-19 vaccine and lead to a surge in breakthrough infections and reinfections.
Dong Li, the chief physician of the Department of Respiratory and Infectious Diseases of Beijing You 'an Hospital, once said, "XBB is still a branch of Omicron, and it is a recombinant mutant with a mutation below BA.2, and its immune escape ability is enhanced, resulting in an increase in the number of infected people in some foreign regions, but foreign data show that its pathogenicity is no different from that of previous strains."
Domestic communication situation
Pan Yang, a researcher at the Institute of Infectious Diseases and Endemic Diseases Control of the Beijing Center for Disease Control and Prevention, said that the recent social monitoring data in Beijing showed that no variant strains such as XBB, BQ. 1 were found in the society, and no non-Omicron variant strains such as the original strain and Delta were found.
Xu Wenbo, director of the Institute of Virology of China CDC, said that three viruses, BF.7, BQ. 1 and XBB, were introduced into China in the past three months, and more than 30 branches of Omicron/kloc-0 were imported into China, among which 49 cases of BQ. 1 and its branches were detected in 9 provinces and 65,438 in 3 provinces.
Risk of reinfection
Wang Xinyu, deputy director of the Department of Infectious Diseases, Huashan Hospital affiliated to Fudan University, said that the pathogenicity of XBB, BQ. 1 and BQ. 1 were similar to the previous strains, but their immune escape ability was improved. Therefore, the virus may spread faster than before. If you encounter these strains, the probability of reinfection mainly depends on two aspects:
On the one hand, how much the new strain overlaps with BA.5 and BF.7? If the virus continues to mutate, the cross-protection effect will be reduced, which may cause infection. On the other hand, it depends on the level of human autoantibodies.
Is it necessary to hoard medicine?
Dong Li once said that montmorillonite powder is a drug for diarrhea. Some infected people in COVID-19 do have symptoms of vomiting and diarrhea, and usually they can relieve themselves within 1 3 days. It is not found that XBB 1.5 is more likely to invade cardiovascular and cerebrovascular systems and digestive systems. Drugs for respiratory tract infection and digestive tract infection can be prepared properly, but there is no need to hoard them in large quantities. How powerful is the news │XBB. 1.5? Is it necessary to store montmorillonite powder?
It is not good to blindly hoard such drugs. Norfloxacin belongs to quinolones. There are many kinds of quinolones, but these drugs will affect cartilage development. Parents who are very concerned about their children's height and size should be especially alert to the risk of abuse of such drugs by minors. For adults, norfloxacin may kill the normal flora in the intestine and destroy the microecological environment of the intestine. Montmorillonite powder should be used with caution.
Hoarding drugs does not mean abuse, but we must be alert to the increased risk of abuse. Therefore, when antidiarrheal drugs are out of stock and rushed to the hot search, it is necessary to carry out extensive popular science propaganda on the newly snapped up drugs. The composition of compound cold preparation is complex, and it is easy for people to repeatedly use drugs unconsciously; The accumulation of quinolones increases the risk of abusing antibiotics ... the side effects of drugs are awesome, and hoarding drugs can't just see the uncertain positive effects and turn a blind eye to the potential risks. Once again, there is really no need to snap up antidiarrheal drugs | Beijing News Quick Review
At present, the mutant strain of Omicron is still mutating. According to the observation of the World Health Organization, Omicron has at least hundreds of subfamilies. XBB is only a small branch of Omicron, and the evidence observed so far is that its pathogenicity and lethality are not strong, but its immune escape ability is enhanced.
The best way to avoid the secondary infection and infection caused by XBB. 1.5 is to vaccinate the booster vaccine. Of course, newly infected people can wait four to six months before taking the second booster vaccine. Pay attention to self-protection before and after the Spring Festival, wear a mask when going out and wash your hands frequently. Persistent fever, dyspnea, nausea, vomiting, diarrhea and other serious digestive symptoms after infection, poor mental state, aggravation of the original basic diseases, etc. You need to see a doctor in time.
We have experienced great storms, so there is no need to worry too much on the basis of good protection and preparation. COVID-19 XBB mutant is coming, stay concerned but don't be afraid | Beijing News column.
