As of February 8, more than 106 million cases of the virus have been confirmed worldwide, including nearly 27 million in the United States, according to real-time data from Johns Hopkins University.

According to the China News Service on February 8, the cumulative number of confirmed cases in the United States has reached nearly 27 million, with more than 463,000 deaths.
According to a digital model published by a team of researchers at Columbia University, on any given day, the actual number of active cases in the United States — people newly infected or still infectious — may be 10 times the number of officially reported cases on that day.
The situation is even worse given the current number of active cases.
On average, infected people are contagious three to four days before symptoms appear, said lead researcher and Columbia University infectious disease expert David Shaman.
So the study also counted those who were infected before and those who are still spreading the virus.

Meanwhile, the new crown variant is spreading rapidly in the United States.
Novel coronavirus, a variant previously found in the United Kingdom, is spreading rapidly in the United States and has even seen significant community spread, a new study finds.
The study estimated that the mutated virus was 35 to 45 per cent more infectious than earlier versions of the virus that had emerged in the US.
But many people infected with the mutated virus in the United States have not reported recent international travel, suggesting that the virus “has had significant community transmission throughout the United States.”

It’s worth noting that the outbreak’s rapid spread comes just before the Super Bowl.
The 55th annual Super Bowl of the National Football League (NFL) will take place in Tampa, Florida.
The Super Bowl will also increase the spread of the disease in the United States.
On Feb. 5, Fauci, the nation’s top infectious disease expert, also warned that “everyone can enjoy the Super Bowl, but don’t have large crowds gathering indoors, especially if there’s not good ventilation.”
On the same day, the director of the U.S. Centers for Disease Control and Prevention urged Americans not to party, but to stay at home and watch the broadcast, so that the Super Bowl does not become a viral event.

, assistant researcher, of the China institute of contemporary international relations in the United States institute Sun Chenghao, according to the current outbreak in the United States have no obvious improvement, the vaccine in distribution and inventory problems in such aspects as the current epidemic situation is relatively serious, while on the mend, but certainly not to the extent to which a big sporting event, the cluster sex is a big sports event might lead to a greater risk of the disease spread.

When a new strain of the virus was reported in Wuhan in December 2019, no one expected it to spread quickly.
In the early days of the outbreak of the virus, the Chinese people struggled to fight the epidemic, but the West was all kinds of “cynicism”. When the virus spread around the world and the West was not able to fight the epidemic, it quickly cast the blame for the origin of the virus on China, trying to divert the conflict.
As a result, the public opinion battle between China and the West about the origin of the virus began, and the WHO also gave an answer to the question of whether the virus originated in China.

, according to the Russian satellite news agency reported on February 3, who experts on a visit to wuhan virus research institute, at the end of visit, who experts, st Petersburg deco, deputy director of the institute of epidemiology and microbiology praised the facilities and the system of wuhan institute of virus, and expressed “very difficult to imagine there can leak”.

(WHO experts interviewed)

According to reports, after the trip to Wuhan, WHO experts said that although Wuhan seafood market is the earliest spread of the place, but this can not prove that novel coronavirus originated in China, and after the Western mouth of the “source of virus leakage” of the Wuhan Institute of Virus, also denied the Wuhan Institute of virus leakage after the actual investigation.

Even so, the West is still trying to pin the blame on China for the origin of the virus. Even before the WHO experts had reached a conclusion, Antony Blinken, America’s new secretary of state, said that China had invited WHO experts to investigate, but that it was not “transparent” enough.
As for what’s “opaque”, blinken is emphasized that China a lot of information is not open, concrete is what also could not say why, from this attitude that is know, no matter what conclusion who, in the west “is the result: I said that the virus spread from China, will come out from China, not have to be.

(Foreign Ministry Spokesperson Wang Wenbin)

In response, Chinese Foreign Ministry spokesman Wang Wenbin said at a press conference at home and abroad that he hoped the US side would follow China’s lead and invite WHO experts to carry out tracing research in the US.
Not long ago, our officials pointed the finger at the Fort Detrick biological laboratory in the United States, saying that there is a major suspicion.

From the Wuhan Military Games of 2019 to the sudden shutdown of the Fort Detrick biology lab just before the Novel Coronavirus outbreak, the evidence suggests that the leak from Fort Detrick, if not 100 percent certain, is sufficiently suspected to warrant at least an investigation.
Now that the World Health Organization has ruled out the Wuhan Institute of Virology as a suspect, what remains to be investigated is the Fort Detrick Biological Laboratory in the United States?

(Fort Detrick Biological Laboratory)

When it comes to the Fort Detrick Biological Laboratory, even native Americans are worried about it.
The Fort Detrick Biological Laboratory, founded in 1942, began researching germ warfare and had ties to the infamous Japanese Army Unit 731.
Over the past few decades, the lab has been suspected of “accidentally” leaking the virus in several outbreaks of biological illness in the United States.
In the United States, conspiracy theories about the Fort Detrick Biological Lab have never died down.

The Fort Detrick Biological Laboratory is the only P4 laboratory in the United States, and the United States is also under curfew, not allowing unaffiliated people to enter the area.
Unlike China, which welcomes the WHO to investigate, the US is adamant that neither the WHO nor the BBC will open the Fort Detrick biological laboratory. If the Americans think they are innocent, why not prove their innocence?

The new mRNA crown vaccine can embed the virus gene into the human chromosome through reverse transcription, so that the vaccinated person will become a genetically modified person.
90% of novel coronavirus can be killed by tea within a minute;
The “winter magic” self-heating underwear applies a variety of technologies, can be self-heating, maintain a constant temperature of 37℃……
Is this all true?
Not too!
The January list of “scientific” myths, published on January 31st, dispels such myths.

The monthly “science” rumors list is jointly released by Beijing Association for Science and Technology, Beijing Cyberspace Administration, Capital Internet Society, Beijing Association of Science Journalists and Editors, and the website dispelling rumors platform in Beijing.

1. Vaccination with the new crown vaccine changes human genes

Rumor:

The mRNA new crown vaccine would insert the virus’s genes into the human chromosome through reverse transcription, thus turning the vaccinated person into a genetically modified person.

The truth:

Currently, there are two main types of vaccines approved for the market: one is an mRNA vaccine, and the other is an inactivated vaccine.
No matter what kind of vaccine, it will not change the human gene, let alone turn the recipient into a “genetically modified person”.

Inactivated vaccine makes novel coronavirus lose its infectivity and replication ability through chemical methods, and at the same time retains the response activity that can cause human immunity. It belongs to the traditional and classic way of vaccine preparation, and does not belong to genetic engineering vaccine, so “changing human genes” is out of the question.

The novel coronavirus vaccine is mainly produced by genome sequencing and analysis, and a part of the gene encoding the spiking protein of novel coronavirus is used as the antigen to produce vaccine.
The mRNA new crown vaccine contains just one sequence of the virus’s nucleic acid that encodes a protein. Human cells then synthesize the protein using their own components and the template of the virus’s mRNA.
Its viral nucleic acid material is neither integrated into the human cell genome nor replicates and expands in the cell.
Cell not only was not hijacked by virus, instead the protein that uses them to synthesize together trained a batch of “mercenary army”, again with “mercenary army” guard against the enemy that invade — novel coronavirus.

Most importantly, the mRNA vaccine does not need to enter the nucleus to express the antigenic protein. The immune cells in the body will actively enrich (collect) the antigenic protein and, through a series of molecular mechanisms, produce the neutralizing antibody.

Novel coronavirus is an RNA virus, but not a “retroviral RNA virus,” so the gene for a novel coronavirus does not integrate into a human chromosome.
Chromosomes, which carry the human genome, are found in the nucleus, which is surrounded by a nuclear membrane.
In the case of an mRNA vaccine, the vaccine’s nanoparticle carrier simply carries a piece of the virus’s gene into the cytoplasm, not into the nucleus at all.
If you can’t even get into the nucleus, how can you get integrated into the human genome?

So the idea that you would become a genetically modified person if you were vaccinated with the mRNA crown vaccine is completely alarmist.

2. A wrinkle in the earlobe can predict coronary heart disease in advance

Rumor:

Atherosclerotic disease can be predicted by earlobe folds.

The truth:

The earlobe is mainly composed of connective tissue without cartilage or ligaments, and its blood supply comes from the posterior auricular artery and the anterior auricular branch of the superficial temporal artery. Ichaemia may lead to the contraction of the earlobe skin and the formation of folds, which is a normal physiological phenomenon and has no inevitable connection with coronary heart disease.

Coronary heart disease is the heart disease caused by coronary artery atherosclerotic lesions and vascular stenosis or obstruction, resulting in myocardial ischemia, hypoxia or necrosis.
In short, the blood vessels supplying blood to the heart are narrowed, and the heart is not supplying enough blood, so the body shows a series of symptoms such as chest tightness and chest pain.
According to the Guidelines for Primary Prevention of Cardiovascular Diseases in China, in addition to uncontrollable factors such as age, gender and inheritance, hypertension, dyslipidemia, diabetes, obesity and overweight, smoking and poor dietary habits are all independent risk factors for CHD.

Studies have shown that the mechanism of earlobe folds may be related to special sleeping position, genetic background, premature aging, oxidative stress, collagen degradation, etc., but the specific mechanism remains unclear.
Earlobe folds have never been included in the diagnosis and treatment guidelines of coronary heart disease, expert consensus, and medical textbooks at home and abroad, which shows that the guiding significance for doctors is not great.
Clinically, the diagnosis of coronary heart disease by a cardiologist should be based on the patient’s history, clinical symptoms, physical examination, electrocardiogram, echocardiography, myocardial markers, coronary CT, coronary angiography and other related examinations, which are obviously more reliable than the observation of earlobe folds.

3. “Self-Heating Underwear” can heat itself

Rumor:

The “magic device for winter” self-heating underwear can heat up by itself and keep a constant temperature of 37℃. A variety of black technology is applied.

The truth:

Most sellers of hot underwear claim that their underwear has a layer of “high-tech” material, can heat themselves, the thermal effect is several times that of traditional cotton thermal underwear, is “black technology” and so on.

From the point of view of the law of conservation of energy, spontaneous heat is not scientific, because energy needs a source, heat can not be created out of thin air.
At present, there is no material in the world that can really heat itself, that is to say, there is no real sense of self-heating clothing.

So-called spontaneous heat underwear is actually the fiber “hygroscopic fever” principle of the concept.
It’s well known that the stratum corneum on the surface of your skin expels water, and when your skin radiates water vapour outward, this water vapour dissipates heat as it liquefies, which is an important reason why we feel cold in the winter.

Generally speaking, it’s best to wear heavier clothes to protect you from the cold.
Static air has the lowest heat conductivity. The more air the fiber layer can hold under the premise of no air flow, the better the warmth retention of clothing will be.
However, bulky and heavy clothes, while useful for keeping warm, are not only ugly to look at, they are also inconvenient to move around.
So garment makers are starting to work on fabrics that are thin and light enough to fit easily on and off.
On the other hand, if the thermal performance is good enough, fibrous material is a good choice.
When the fiber absorbs water, the hydrophilic group in the fiber molecules combines with the water molecules, and the kinetic energy of the water molecules (water vapor) is reduced and converted into heat energy to be released, which is hygroscopic heating.
The higher the hygroscopicity of the fiber, the more heat dissipation during hygroscopicity.
Therefore, the so-called spontaneous heat underwear, in fact, is the use of special fiber materials, with “moisture absorption and thermal” effect of underwear.
For example, a brand of self-heating underwear, the main material is polyester fiber and viscose fiber, in which acrylic fiber is responsible for keeping warm, viscose fiber is mainly responsible for air permeability and sweat, incidentally to help keep warm, polyester is responsible for anti-wrinkle, spandex is responsible for making clothes more close to the body.
With the continuous increase of “heating capacity”, it can be seen that the proportion of the sum of viscose fiber and acrylic fiber increases generally.

Self-heating underwear is actually warmer than regular long Johns when the fibers and ingredients are “recombined”.
However, spontaneous hot underwear affected by the environment is greater, in a very dry environment there is no heat absorption capacity, such as in the winter of dry and cold northwest, north China, spontaneous hot underwear effect certainly not as good as the Yangtze River basin.
In addition, maintaining a constant temperature is not an easy thing to do, the fiber hygroscopic reach saturation, water absorption is less, this time the heat is less.
According to the principle of conservation of energy, the moisture absorbed by fiber materials also needs to be released, which is also a process of “heat absorption and moisture dispersion”, that is to say, spontaneous hot underwear has actually been in the process of hygroscopic – heat release – moisture release – heat absorption cycle, which is not good for some people with sensitive skin.

4. Eating lard is good for the heart and blood vessels and has a health effect

Rumor:

Eating lard is good for the heart and blood vessels and has health benefits. Lard is a treasure.

The truth:

Lard does have some nutritional value. It provides essential fatty acids, promotes the absorption of fat-soluble vitamins, and provides calories.
The fat intake from the diet is an important source of body heat supply.

But lard is not a health food.
The main component of lard is fat, and a large part of it is saturated fat, which has no special effect on human health and can not cure diseases.

In addition, lard energy is too high, eat more is not conducive to health.
It is best not to consume more than 25 percent of the body’s total daily energy from fat.
For an adult who needs 2000 kcal a day, the amount of saturated fat intake should be limited to around 22g a day.
If all of it is converted into lard, it is about 56 grams.
If the fat supply ratio is more than 30%, it is easy to suffer from a variety of chronic diseases, the most common is cardiovascular disease.
Numerous scientific studies have found that high intake of fat (especially saturated fat) and high energy intake increases the risk of cardiovascular disease.

So to claim that eating lard is good for your cardiovascular health is putting the cart before the horse.

5. Tea can kill novel coronavirus

Rumor:

Ninety percent of novel coronaviruses can be killed by tea in less than a minute, and 99.9 percent can be killed by tea in less than 10 minutes.
The video of Qiao VIP, chief physician of the Department of Thoracic Surgery of Guangdong Provincial People’s Hospital, verified this conclusion.

The truth:

The research refers to the study of “the inactivation effect of different teas on novel coronavirus” by a team led by Toichi Yano, a professor of microbiological infectious diseases at Nara Prefectural Medical University in Japan.
The article concluded that the study did not demonstrate that tea consumption could prevent novel coronavirus infection.

In addition, the study was conducted in vitro, in other words in vitro.
Studies that kill the virus in vitro do not directly deduce the results of drinking it into the body.
To date, there is no complete evidence-based evidence for the prevention or treatment of novel coronavirus infection by drinking tea alone, either at the cell level in vitro, in vivo, in vivo or in clinical trials, or in dose-related studies. Therefore, we still need to take strict personal protective measures.

On January 7, 2021, the official microblog of Qiao VIP, chief physician of thoracic surgery department of Guangdong Provincial People’s Hospital, published an article titled “About the Internet” Tea can kill novel coronavirus “, which invites netizens to wipe their eyes!
To dispel rumors.
Qiao VIP director pointed out that the network video was taken out of context, the head and tail, the rumor into a rumor, please keep your eyes bright, do not believe the rumor.

Current anti-epidemic measures may not be effective against the mutated virus

“Like a speeding car with no brakes.”
The United States “Washington Post” describes the mutant novel coronavirus that is ravaging all over the world in this way.

There is new bad news from Denmark.
The country’s scientists found that the mutation novel coronavirus found in Britain not only spread at an alarming speed, but also to a certain extent “immune” to the world’s current widespread implementation of anti-epidemic measures.
In other words, humans are losing many of their weapons against the mutant novel coronavirus.

Despite the strict blockade in Denmark, the number of cases of the mutated virus has increased by 70 percent in just a week, the Associated Press reported, citing the Danish National Serum Institute.

“We are losing some of the tools to control the epidemic.”
Said Tara Grove-Kraus, the institute’s scientific director.
In mid-January, the institute began sequencing all positive samples to look for mutations in the virus, AP said.
By contrast, the United States has sequenced only 0.3 percent of cases and ranks 43rd in the world.

On January 22nd Boris Johnson, Britain’s prime minister, and his advisers suggested for the first time that the mutated strain could be deadlier than the original.
Patrick Vallans, England’s chief scientific adviser, gave an example: The original novel coronavirus killed 10 out of every 1,000 infected men aged 60 or older in the UK, while the mutant virus killed 13 or 14, The Guardian reported.
This represents a 30 percent increase in mortality.

Johnson and his scientific advisers have repeatedly stressed that existing vaccines are still effective against both original and mutated viruses.
Dr. Vallance did not explain why the mutated virus could cause more deaths.
Is the virus becoming more virulent, or is it becoming more transmissible, overburdening the health care system and failing to stop the deterioration of supposedly curable cases?

Danish public health officials say that without extensive testing and large-scale sequencing, they might still be basking in blind optimism.
The number of new cases per day in the country has been falling for a month.

“Without the mutated virus, we’re in pretty good shape.”
Camilla Holten Muller, co-head of the Virus Transmission Modeling Group at the Danish National Serum Institute, told the Associated Press.

The mutated virus, called B.1.1.7, is spreading so fast that Denmark predicts it will become the dominant strain in the country as early as mid-February.
As a result, the country could be reporting four times as many cases a day by early April.

Research by the Danish Institute of Public Health shows that in the worst cases, the number of cases skyrockets, even when strict blockade measures are in place.
Barring a miracle, such as a mutated virus that is less infectious than expected, or a rapid precipitous fall in the number of new cases in Denmark, the outbreak could spiral out of control, AP said.
Vaccination efforts are helpful, but not urgent.

“It was a bit like a tsunami.
You stand on the beach and you see the water receding all the way, the tide ebbing.”
“Then the tsunami comes roaring in and swallows you up,” Klaus said.

On January 22, British Prime Minister Boris Johnson said at a briefing on the outbreak that the mutation novel coronavirus found in the UK spreads faster and is likely to cause a higher death rate.

“When you realize the water is rising, it’s too late.”

On December 14, 2020, Klaus received his first warning.
Virus researchers in the United Kingdom have collected a novel coronavirus that appears to be spreading widely in the country.
When the Brits submitted the new virus to a public virus database, they were surprised to find that Danish researchers had found the mutated virus in three confirmed cases, suggesting that the more aggressive strain had spread outside the UK.

According to the Associated Press, the mutated virus entered Denmark as early as November 14, 2020, and began to spread in the country.

When the new threat B.1.1.7 was identified as dangerous, Denmark already had strict precautions in place: the reopened primary schools were closed again;
No more than 5 people are required to gather in public places;
Non-essential international travel is banned, and people entering the country must provide proof of a negative nucleic acid test within 24 hours before entry.

Denmark has launched a vaccination program that is one of the fastest running in Europe, The Guardian reported.
Britain and the United States approved their first vaccines earlier, but Denmark pulled ahead.

Despite this, the number of cases of infection B.1.1.7 has increased exponentially.
As of January 17, Denmark had recorded 464 cases of the mutated virus, the Associated Press said.
B.1.1.7 cases accounted for 2% of the novel coronavirus sequencing conducted in the country in the last week of 2020;
By the second week of January, that figure had risen to 7 per cent.

Concerned Danish leaders are trying to explain why the blockade needs to continue when overall indicators are good and it seems that it should have been gradually lifted weeks ago.

U.S. cable news network (CNN) reported that in early January, the Danish prime minister mei, Fraser rick’s made a long post on facebook and let people imagine yourself sitting in Copenhagen park stadium at the top: this can hold 38000 people in the stadium have a leaky faucet, is a trickle irrigation to the venues, a drop for the first minute, two drops 2 minutes, the third minute 4 drops…

At that rate, Fraserickson said, the stadium would be filled with water in 44 minutes.
For the first 42 minutes, though, the stadium looked almost empty.

“The point is, when you realize the water is rising, it’s too late.”
She wrote.

Danish officials say they are running a “race” to vaccinate as many people as possible before the mutated virus becomes too dangerous to control.
The government believes this will be key to containing the epidemic.

But the pace of vaccination may not be fast enough.
At the current pace, mass vaccinations will not begin until April at the earliest, and unpredictable production delays could slow the schedule.

On January 21, Fraseriksson joined several EU leaders in an online meeting to urge the European Medicines Agency, which approves vaccines in the EU, to speed up the process.
CNN reported that the agency is reviewing vaccine maker AstraZeneca’s vaccine, which has been approved in the United Kingdom and is expected to be available in mid-February.
But AstraZeneca announced on January 22 that it would not be able to deliver the volumes expected by the EU in the first quarter of this year.

People are once again working from home.
Copenhagen’s once-bustling bike lanes have quieted down and shops selling non-essentials have closed.
Preschool education is one of the few areas still open and a potential target for further government tightening.

“It’s the strange calm before the storm.”
Michael Dahl, chief medical officer at Odense University Hospital, told CNN.
The hospital, the largest in southern Denmark, is preparing a dedicated Covid-19 unit and is confident of having enough beds to accommodate the surge in patients.

But Dahl worries that workers could be cross-infected with their families, undermining their efforts.
What good is it to have a ward if all the medical staff are sick?

“If this mutated virus is more contagious, we will end up with a bigger problem in many ways.”
Dahl said.
