Recently, a large number of netizens have questioned experts for fraud and questioned the accuracy, authenticity and scientificity of the prevention and control data before the release.
Before the policy was relaxed, experts said that after three years of prevention and control, the new coronavirus variant Omicron variant strain was highly contagious and weak in virulence. Experts say that before the release, 90% of the cases were asymptomatic or mildly symptomatic. But less than a month after the release, everyone felt that the infected people around them were infected with typical symptoms; every hospital, fever clinic, and ICU had gathered a large number of critically ill patients; a large number of hospitals were at risk of being overrun! Even the medical staff lamented: Why are all the people they see in the makeshift hospital asymptomatic infected people, but they don’t understand why all they see after they are released are typical pneumonia patients?
Even the famous program host Bai Yansong also expressed concern about this issue. He specifically contacted Liang Wannian, an expert from the National Health Commission: Why is it that everyone has symptoms and many are seriously ill? Liang Wannian believes that it may be related to the differences in pathogens, climate, and population structure.
In fact, as a doctor, I am more willing to believe in the work and efforts of scientists. I am unwilling to question the conclusion that so many people from different places, different laboratories, and different research groups around the world have unanimously concluded that " Omicron strain is highly contagious, has a low severity rate, and a low mortality rate." Otherwise, experts would not be able to act as responsible persons and make such voices to the public.
Don’t forget that there are many different environmental factors, time factors and disease-causing conditions before and after liberalization. If you think carefully, you may not have such confusion.
1: First of all, it may be that the scenes before and after letting go are different.
Before the release, whether they entered the makeshift hospital or other isolation points or treatment hospitals, the new coronavirus-positive "patients" were almost all high-density or sub-close contacts who were "caught" from different closed areas. They have the characteristics of short contact time with the source of infection and low infected viral load . Therefore, they are more in line with the characteristics of asymptomatic infected persons. However, infected persons after release are more likely to not know who the source of infection is, and there is a chance of repeated infection. It may be because of the repeated stimulation of virus and the opportunity to continuously accumulate viral load, and they are more likely to naturally express themselves as symptomatic infected persons.
2: A concentrated outbreak triggers the butterfly effect above . It is indeed a relatively short time for
to go from the optimization of National Article 20 to the launch of National Article 10. In addition, the cold winter season is the climate environment where viruses are active. Because the highly contagious virus has gained unlimited infection opportunities, it has led to the above butterfly effect, which has led to a concentrated outbreak of the epidemic. In a short period of time, the pressure on medical institutions has been sharply increased, the shortage of emergency medicines has been increased, and the cash flow phenomenon has occurred.
3: A large number of asymptomatic infections and mildly infected patients have been hidden from medical treatment;
Before the policy was relaxed, all COVID-19 positive people had to be quarantined together, because these groups have the characteristics of asymptomatic infections, but after the policy is relaxed, "patients" like this will definitely not take the initiative to go to medical institutions, especially large medical institutions. Even those with mild infections are more likely to recuperate at home or seek treatment at a nearby clinic, rather than going to a medical institution. In addition, after the policy is liberalized, nucleic acid testing has become an irreversible fact. More asymptomatic infections no longer know that they have the new coronavirus infection.
Four: Hospital classification, differentiated diagnosis and treatment scope;
With the liberalization of policies, under the current medical grade system, all patients with typical symptoms, especially the elderly, pregnant women and children, have the independent right to choose medical institutions with better conditions for medical treatment and treatment. As we all know, my country's current medical conditions are still insufficient in terms of emergency and ICU equipment. When a large number of people have fever, difficulty breathing, or the elderly require emergency treatment in a short period of time, the contradiction will become obvious. The larger the medical institution, the more obvious the difficulty and pressure of first aid will be.
5: As Mr. Liang said: may be related to differences in pathogens, climate, and population structure.
6: Although we believe that the current mainstream virus is the Omikron mutant strain, is there the possibility of other mutant strains? For example, will there be delta virus in a small number of different regions? We still don't know this yet, and the facts await further observation by scientists.
