Hello everyone, today is Saturday, October 8, 2022, the 50th text version of Lao Wen Ranbo.
In recent months, there has been a huge voice in calling for the full liberalization of epidemic control. I have also seen some media and self-media say that the toxicity of the new coronavirus has become less and less, and it has become a big cold.
Many foreign countries, including the United States, have also announced the complete relaxation. No longer take prevention and control measures, accept coexistence with the virus, and everything returns to normal life. Some people in China are very envious.
But Lao Wen has always felt that this is not a good phenomenon. Because humans still know very little about this virus and have no effective control methods, will everything be fine if the symptoms disappear? Lao Wen couldn't help but remember the sequelae of SARS patients.
The SARS epidemic lasted for a very short time, so the public did not know much about the sequelae caused by SARS. The biggest harm of SARS is that it causes irreversible and permanent damage to the human lungs. Many people save their lives, but permanently lose their ability to work.
The new crown lasts much longer than SARS and has much more mutations. What kind of long-term harm will it cause to the human body? Many of the sequelae will not be reflected slowly until a few years later. This is probably the same as developing a new drug that requires more than 10 years to verify its toxicity, efficacy and side effects.
A research report from scientists sounded the alarm bell for the argument that "the new crown is a large flu, and we call for full liberalization."
A study report from the University of Queensland, Australia pointed out that the new coronavirus is likely to have a direct impact on the heart's DNA, not just by triggering inflammation, causing a chain reaction. Compared with the flu pandemic in 2009, the new coronavirus has caused more serious and long-term cardiovascular disease. Dr. Kurasinha of University of Queensland, one of the authors of the study, said that DNA damage and repair mechanisms can cause genome instability and are related to chronic diseases such as diabetes , cancer, atherosclerosis and neurodegenerative diseases. University of Queensland professor John Fraser said the study showed that the coronavirus and influenza viruses have different effects on heart tissue, which provides more evidence that the coronavirus is not "similar to the flu virus."
In people's original impression, the harm of the new crown seems to be concentrated in the lungs. This report further reminds the harm of the new crown in front of the world.
Some netizens pointed out: As a permanent cell, the myocardium does not tend to divide and differentiate. The new coronavirus integrates its own genetic material with the host myocardium DNA, showing aggressiveness to the myocardium, which may change the metabolic characteristics and functional structure of the myocardium. The new crown has changed from a main attack on lung tissue to multiple tissues and organs throughout the body.
What are the sequelae of the new coronavirus that Lao Wen is very concerned about?
1. Interstitial fibrosis of the lungs: mainly affects some patients with severe pneumonia, and diffuse interstitial lesions in both lungs. When the novel coronavirus is cleared, pulmonary fibrosis will be left behind, which is manifested as long-term cough and shortness of breath.
2. Renal function impairment: The virus affects the patient's kidneys, and acute kidney injury may occur. After the patient recovered from novel coronavirus pneumonia , he developed chronic renal damage and affected renal function.
3. Heart damage: manifested as chest pain , palpitations , myocarditis .
4. Changes in smell and taste: Patients with the new coronavirus may experience weakening of smell and taste or even disappear after being cured.
5. Mental and psychological disorders: Patients suffering from the new coronavirus may experience symptoms such as anxiety, insomnia, and depression after being cured.
or above is just some information collected by Lao Wen, and it is not comprehensive, and its harm is far more than this.
There is now a new term called: Long Covid. Also known as long-term COVID-19, it refers to a syndrome that appears after infection with the new coronavirus and manifests as a series of confusing symptoms.
Data released by the UK's National Bureau of Statistics on the 6th showed that as of September 3, more than 2.3 million people in the UK had long-term sequelae of the so-called "long-term coronavirus" after being infected with the new coronavirus, accounting for about 3.5% of the total population of the UK.
On September 19, American patients with "long-term COVID-19" gathered outside the White House to protest, calling for emergency response measures by the government.
Most of the people participating in the protest suffer from chronic fatigue syndrome . Protesters said they were sick or even disabled due to the symptoms caused by the "new crown". Protesters here call on the government to take urgent action, hoping that the White House will declare a state of emergency on the issue of "long-term COVID-19". According to data provided by protest organizers, 75% of the population with chronic fatigue syndrome in the United States are unable to work and 25% are still in bed.
What is the experience of chronic fatigue syndrome and the new coronavirus?
Let’s listen to the self-report from a British patient. Ravi Viria Jacques, a 23-year-old young man, is the son of a famous British scholar Martin Jacques. He said: The long-term COVID-19 has had a disastrous impact on my life. My main symptom was feeling debilitating fatigue and I had to spend nearly 16 hours in bed every day. I can hardly do anything I like. I can't walk for more than 15 minutes, and before I had to ride a bike a few times a week, 20 miles a day. It is difficult for people who have not experienced fatigue to experience this feeling. Even resting cannot let this extreme feeling of fatigue disappear. If you are overworked, the fatigue will become more severe, making it difficult to walk, stand, and even go to the toilet. You end up almost becoming a prisoner of your own body. In addition to fatigue, I also have various secondary symptoms, which are characteristics of long-term COVID-19. I lost my sense of smell and taste, had mild tinnitus , and also had mild gastrointestinal problems.
Some people may say that from the online media, many people have no particularly serious symptoms after getting the new crown, and they recover very quickly, and some are even milder than colds, not to mention any sequelae. I think this may have a survivor bias phenomenon. Those who can speak and feel complacent after getting COVID-19 must be those with mild symptoms and feel good about themselves. The dead can no longer speak. He would not talk about it everywhere because the disease is extremely contagious and can lead to such serious consequences because he is afraid of being alienated and excluded.
The new coronavirus is very cunning. Continuously adapt to the human body and escape the human immune system. After multiple generations of mutations such as alpha, beta, gamma, delta , Omickron , etc. Now Omickron also has multiple mutation branches. How will he develop? I'm afraid the scientific community has not yet made a clear judgment.
A netizen said it well: In the past, we would think that this disease would either mutate into extremely fatality in the end, just like Ebola . It is certain that the whole world actively prevents the epidemic and can be eliminated soon. Even if it cannot be eliminated, the patient will die quickly and stop spreading. Or it will mutate into extremely high infectiousness, with extremely high infectiousness often low in mortality, and in the end it will really turn into large flu, so there is no need to be prevented. But we have ignored one thing, that is, there is another virus, which is extremely contagious and has a very high mortality rate, because it does not die immediately after being sick. It has a long incubation period, which is enough to ensure that the virus is spread to as many people as possible. In the end, the patient's death is not because of the disease itself, but because of the disease that causes the reduced immunity and eventually dies from other bacterial infections, which also makes it extremely difficult for people to be vigilant. It finally took a long time to be discovered and taken seriously. This disease is AIDS . The new crown seems to have begun to have some typical characteristics of AIDS, such as the "new crown". The patient has obviously no symptoms of the new crown "pneumonia", but he has begun to fall into an extreme sub-health state.
In this world, there are not only healthy people, but also sub-healthy people, and people with severe underlying diseases such as chronic diseases. I just hope that when the virus can afford the damage to the human body, we will talk about full coexistence. Faced with these uncertainties, I still agree with an active defensive policy. As for foreign countries, just think they are a large-scale clinical trial. When it is confirmed that it is safe, it will not be too late for us to open up in full swing.If the experiment is not successful, then we will gain a comparative advantage, and as a commoner, I am happy to see it happen. Now, we must not let them get into the water.
I am Lao Wen, thank you for watching Lao Wen play randomly. See you next time.
