Recently, the Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, announced at a press conference in Geneva that the new crown epidemic no longer constitutes a "public health emergency of international concern", which means that the new crown pandemic has finally passed. Of course, whether to listen to the specific obedience or not, it is the opinion of various countries, anyway, the WHO has always had no power.
What is a Public Health Emergency of International Concern? If it no longer constitutes a PHEIC event, is the virus completely gone? What should we do later as ordinary people? Let's talk to you today.
First, PHEIC "theoretically" has guidance for the international community
A public health emergency of international concern (PHEIC) is "an extraordinary event through the international spread of disease that poses a public health risk to other countries and may require a coordinated international response." ”
So [theoretically] countries need to adopt a [coordinated] international response based on WHO advice.
But, actually, everyone saw it. When the new crown initially needed to be isolated, countries loved freedom, and later they were infected, and they began to force others to be infected with the virus, and in the end, everyone decided to play together, and as a result, some countries began to restrict again. In fact, this also shows that the WHO is an x on this.
In fact, it is also true, international public health emergencies are not literal, but proper nouns, so whether this thing is true depends entirely on the WHO's opinion, so PHEIC has been announced a total of 6 times in history:
1. 2009 H1N1 influenza virus outbreak
2. 2014 wild-type poliovirus outbreak
3. The 2014 Ebola virus outbreak in West Africa
4. Zika virus outbreak in Brazil in 2016
5. Ebola outbreak in the Democratic Republic of the Congo in 2018
6. In the early morning of January 31, 2020, the new crown epidemic was declared PHEIC
As for the rest of the epidemic, it is enough not to announce it.
Second, it is not PHEIC, which does not mean that the virus disappears
In fact, after reading the above content, you will know the WHO's research and judgment, it is really difficult to say, anyway, this institution has always been like this. However, how about the virus, everyone looks at it, just like the recent example of secondary yang began to appear, in fact, it is expected.
In fact, the new crown has always been there, but before this, our immunity in the body is strong, so we can resist the past. This can be seen from a large number of previous studies.
After the new crown infection, our body will quickly produce antibodies, which are our basic way to deal with the new crown (secretly speaking, in fact, drugs can not directly kill the new crown virus, and it is our immunity that ultimately destroys the new crown virus). And this antibody will gradually decline over time, no way, the human body can not maintain a high concentration of antibodies, that is too energy-consuming, the result is that over time, the concentration of new crown antibodies in our body is getting lower and lower, and the resistance to the new crown is getting worse and worse, and eventually the resistance is reduced, more susceptible to infection.
From last year to now, almost 5 months, many people's new crown antibodies may have dropped below detectable concentrations, at this time, in fact, the resistance to the new crown will drop a lot, and return to the "naked" era, so new infections are inevitable.
On the one hand, antibody concentrations are declining, protection is insufficient, and on the other hand, new virus variants continue to emerge. The new crown virus continues to mutate, which has become a common perception, in fact, this is also the basic characteristics of the virus, as long as it replicates, errors may occur randomly, and these errors accumulate to gain advantages, then a new variant is formed.
In addition, the new crown virus itself is still a single-stranded RNA virus, which is easier to mutate than DNA viruses.
So variants of the new coronavirus have been emerging.
And it is worth mentioning that when the new crown virus mutates in the process, there is another important factor: choice. Our body has always selected the new crown virus, and those who cannot resist immunity are naturally eliminated, and those who can escape immunity are new strains.
And a simple truth is: the new strain that can emerge is likely to break through the past immunity, thus forming a new dominant strain, such as XBB at the beginning of the year. Cao Yunlong, who was previously known as the predictor of the new crown, predicted the new crown virus according to this principle, and according to the immunogenicity of the existing new crown virus, it can be calculated that if a new new crown variant appears, it is necessary to break through the possible mutation sites of the existing immunity, so as to find the next possible mutation.
They predicted Omicron BA.1, BA.4, BA.5, BQ.1.1, XBB, CH.1.1, and the results were also published in nature.
In addition, this May Day everyone is traveling, 274 million people, equivalent to one-fifth of the national population, such a flow of people, will inevitably bring new possibilities for the spread of the new crown, and, compared to before, everyone's protection has also dropped a lot, many people no longer wear masks, convenient is convenient, but also makes the new crown infection easier. So in the next short period of time, it is estimated that there will be a trend of rising new crowns.
Third, pay attention but do not panic, the individual is the first responsible person for health
However, don't worry, because we have come a long way compared to before.
First of all, many people are still immune. In December last year, a major factor in the outbreak of the new crown was that everyone's immunity to the new crown was not high, because it had been a long time since the third injection was completed, and the antibody concentration had dropped very low, so in the face of the arrival of the new crown, everyone was basically running naked.
Secondly, when the new crown outbreak, the short-term new crown virus concentration is also very high. Compared with the current sporadic new crown cases, during the previous new crown outbreak, many people were infected, the virus was everywhere, and the concentration was also very high, in this case, people must be more likely to be infected. But at present, sporadically, the concentration of viruses in the environment is definitely much lower.
Third, medical resources have caught up. In fact, during the new crown, all kinds of rush drugs were a run. And drug production capacity is not enough in the short term, and as a result, the run is intensified, resulting in many people not having enough reserves.
And now the drug production capacity has kept up, all kinds of drugs, such as the previous crazy ibuprofen, acetaminophen has been everywhere, almost how much.
In addition, at present, our new crown drugs have also been approved, not only Pfizer's Paxlovidl, but also Merck's monogravir capsules; Real Bio's Azvudine Tablets, Junshi Biologics' Deuterium Remidevir Hydrobromide Tablets (Mindway), Simcere Pharmaceutical's Sennotevir Tablets/Ritonavir Tablets (Senoxin), and Zhongsheng Pharmaceutical's Leretevir Tablets (Leritin), these drugs are now available in hospitals and can be prescribed.
So at present, we all don't have to worry about it, the rise of the new crown is inevitable, with the first wave of experience, we are now well prepared, everyone is more rational, naturally there is no need to worry about it.
Even if the situation is more serious, the current medical resources are much better than before, directly call 120 can be sent to the nearest hospital, and then the hospital is basically equipped with relevant drugs and treatment measures, can be treated in time.
Finally, it is better to wear masks, this thing really works, not only to prevent the new crown, influenza, allergies are also very good, but also cover the ugly.
