How to prevent XBB strain?

With the continuous optimization and loosening of epidemic control measures, some people have been "involved" in this wave of COVID-19. According to authoritative media reports, most of the strains we are infected with are basically BA.5 or ba.7, which means that we will not be infected for a long time to some extent if there is no big variation in the domestic epidemic strains.

However, things don't seem to develop in the direction we expected. In recent years, the information about "XBB" strain is rampant, which has aroused public concern and even some people's panic.

A netizen posted on the Internet platform, saying: "At present, all the domestic popular ones are XBB. 1.5 little brothers. XBB. 1.5 is mainly aimed at cardiovascular and cerebrovascular diseases, which can cause diarrhea. It is recommended that the public prepare montmorillonite powder, norfloxacin, rehydration salts, probiotics, etc. " However, the relevant departments quickly came out to blame. "After verification, this screenshot exaggerates the pathogenicity of XBB. 1.5, and it is not excluded that people with ulterior motives are promoting products. Many doctors remind you not to take montmorillonite powder, norfloxacin and other drugs mentioned in the screenshot. "

So what exactly is XBB strain? How can we prevent it?

To put it simply, XBB strain is a subtype of Omicron mutant strain, which can be further subdivided into XBB. 1.5 and XBB. 1, similar to BA.5 and BA.7 which are popular in China at present. XBB strain was first discovered in India in August 2022, and has been detected in many countries and regions including China. In addition, it is necessary to say that XBB. 1.5 has become the number one epidemic strain in the United States.

As for how to prevent XBB strains, there is actually no new way, mainly the following routine operations:

The first thing is to continue vaccination (booster injection). In this wave of epidemic, some people responded that the role of vaccine is not prominent, and it is inevitable to be infected after vaccination. Indeed, I personally feel that the vaccine is not so effective in preventing infection, but its protective effect in preventing serious diseases and deaths is undeniable. Without the blessing of vaccines, the impact of this epidemic could be disastrous.

Secondly, we should insist on wearing a mask. At present, wearing a mask is still one of the most effective means to prevent the spread of Omicron, although some people have been to COVID-19 and high levels of antibodies have been produced in their bodies. However, the antibody level in the body will gradually decrease, and there is still the possibility of secondary infection if new variants are encountered.

Finally, do some other daily protection. Wash your hands more on weekdays, keep a social distance, remember to ventilate your home, and don't spit everywhere. These habits don't seem to have much effect, but once formed, they will protect our health and benefit us for life.

I don't think anyone knows where COVID-19's final destination will be, even the so-called experts are taking it step by step. So what we need to do now is to do personal protection and try not to be infected or less infected.
