Yearly Archives: 2020

On July 21, Beijing time, the number of confirmed cases of coVID-19 worldwide has reached nearly 15 million, with more than 600,000 confirmed deaths.
For the first time in the past week, the number of confirmed cases worldwide has risen by more than 200,000 a day.
North America, Latin America and South Asia remain the three most important epicenters.
Sub-saharan Africa is growing strongly and is likely to overtake Western Asia as the new major growth region by the end of July.
South Africa, with a total of more than 300,000 confirmed cases, ranks in the top five.
After the United States, the four BRICS countries — Brazil, India, Russia and South Africa — have the highest number of confirmed cases, accounting for more than 55 percent of the global total.

Economic – regional differences in economic recovery from the epidemic are significant, and there is a lack of momentum for continued recovery since mid-June

Arhat hall set up a universal the evolution of the outbreak of the economic framework, under the framework of every country undergoing preparation – stage response – trough – recovery – the vaccine five stages, and established the outbreak of the global economy in this tracking system, daily tracking outbreaks in 132 countries and regions and economic conditions, accounting for 90% of the world’s population, 97% of the total GDP.
As of July 20, 72 of these economies were in recovery, a net reduction of two from the previous week.
Fifty-three countries, mostly developing countries in Asia, Africa and Latin America, are still coping or at a low ebb.

Economies in recovery, mainly in East Asia, Oceania and Europe, have recovered to an average level of economic activity of 96%, which has been maintained at this level for several weeks.
The average economic activity level of the economies in response period and trough period increased by one percentage point to 92%, but this week, the cumulative number of infections in these economies increased by 1.68 million, the number of existing infections increased by 500,000. The overall epidemic prevention situation is very severe, and the challenge of steady economic recovery remains great.

The level of economic recovery in all regions is closely related to the trend of the epidemic. East Asia still stands out, while Oceania, due to the new wave of the epidemic, has seen its economic activity drop below 95%, on a par with Europe and Southeast Asia.
Latin America and South Asia remain below 90 per cent, while North America has picked up slightly since mid-July.
But overall, economic activity in all regions has not increased significantly in the past month or more, and the global epidemic economy has entered a deep state of anxiety.

Vaccine development has entered a critical period, the outbreak of the fourth quarter of the economy dawned

The vaccine period of the economic framework of The Epidemic in Luohantang

In an epidemic economy, a country has to zig-zg between the two dimensions of containment and economic contraction.
There is not a linear relationship between the duration of the trough and the recovery period and the impact on the economy. As the trough period lengthens, economic losses and negative social impacts may grow exponentially without appropriate responses.

In the five-stage evolution framework of the epidemic economy in Luohantang, the last stage is the vaccine stage. The main indication of this stage is the successful development of the vaccine, which is put into the world and covers the vast majority of the population to achieve true herd immunity and finally realize the end of the epidemic economy.
The pace of economic recovery depends in large part on breakthroughs in vaccine development.
The economy will not be decoupled from the epidemic until the vaccine deadline is met.
Both capacity and cost constraints, as well as differences in the level of demand and access systems among countries, dictate that the vaccine period will last a long time at the global level, until the second half of 2021 and beyond

Global vaccine development progress – a number of technical routes are advancing hand in hand, China has the highest diversity of vaccines, the United Kingdom and the United States have hit products

According to the COVID-19 vaccine tracking system at the London School of Hygiene and Tropical Medicine, there are 218 vaccine development projects worldwide, at least 23 of which are in human clinical trials, spread more evenly across five different technology routes.
Of the 23 coVID-19 vaccines that have entered human trials, nine are from China, of which seven are independently developed in China, and the other two are developed by international cooperation and play a leading role.
The US and THE UK are ranked second and third with five and four, respectively.

In may this year, arhat hall academic committee member, Princeton university economics professor Markus Brunnermeier vaccine and U.S. Treasury secretary Lawrence summers, dialogue, summers that considering the epidemic brought huge economic losses, the total cost of the vaccine development proportion is very small, so the government should fund vaccine research and development with unprecedented strength, but also should pay attention to the research and development in the direction of diversification, and ensure each direction have more than one candidate.
At present, globally, no less than three projects on the five major technology routes have entered the human testing stage, which is optimistic.
By country, China is the only country with at least four technology routes in human trials, and three of them have at least two r&d projects under way.

We have also noted that most of the leading technologies in China are traditional vaccine production technologies, such as the more mature inactivated vaccine technologies that have been used for influenza, measles and other vaccines, which may increase the probability of success.
And abroad enters clinical trial vaccine to be in the majority with new technology.
Some of the new vaccine technologies have shorter production cycles than traditional vaccines and can be produced in large quantities quickly to keep pace with the epidemic response.
At the same time, vaccines developed with traditional techniques produce antibodies more slowly in the body, while some new techniques of cellular immunity express themselves more quickly in cells, producing immune effects that can be used in special situations for emergency vaccination and post-exposure immunity.

According to Luo, the current trend of some redundancy and diversification in the global vaccine development process is necessary to deal with the still highly uncertain situation of virus transmission.
On the one hand, people with different backgrounds in different regions have different degrees and types of exposure to virus images.
On the other hand, we do not fully understand the novel Coronavirus origin, infection path, and the evolution or even mutation of the virus in the process of infection in the coexistence with human, even animals and hosts.
Thus, the effective response is to have multiple vaccines and therapeutics from different countries, companies and technology routes simultaneously to protect the potentially infected from novel Coronavirus.
This is also the fact that the current speed of vaccine development has been greatly accelerated and the time for large-scale clinical testing of vaccines has been greatly reduced, so that the overall production capacity can not only keep pace with the large global demand for coVID-19 vaccines, but also provide more targeted vaccines for different populations.

Could vaccines be the pacemaker for the global economy in the fourth quarter?

By mid-July, a number of vaccine research and development projects had entered the phase III clinical phase, showing a glimmer of hope that the epidemic economy would enter the vaccine phase as soon as possible.
In April of this year, WHO lowered the threshold for vaccine development in its published vaccine guidelines, agreeing that the vaccine would provide 50 per cent protection within six months for those exposed to novel Coronavirus at high risk to advance clinical trials and marketing approval of the vaccine.
The US Food and Drug Administration (FDA) recently gave the same criteria for reducing the risk of infection and disease by at least 50 per cent compared with the placebo group.
Although a few drug companies are more optimistic, such as Pfizer inc. ‘s President, who said approval is possible early in the fourth quarter, the FDA says it won’t lower its standards and aims to have the vaccine on the market by the end of this year or early next year.
The vaccine under phase III clinical trial in China and the UK is also expected to end in the fourth quarter. The recombinant Novel Coronavirus vaccine developed in collaboration with Academician Chen Wei of The Chinese Academy of Military Sciences has become the world’s first vaccine with limited use.

The early development and approval of the first vaccine is of vital importance to the recovery of the global epidemic economy.
Arhat hall academic committee member, 2012 Nobel laureate Bengt Holmstrm at the end of June when the global more than 10 million confirmed cases, points out that will be coronavirus may never be eliminated, but the public and the market’s fear of virus can be reduced to tolerable levels, and only when fear is reduced greatly, the truly would be ready to return to normal.
The arrival of the first successful vaccine will largely calm fears.
So, while insufficient vaccine capacity remains an important limiting factor, if vaccine development goes well, it could be the pacemaker for global or some of the more advanced economies in the fourth quarter.

In the best scenario, if one or more of the vaccine research done on or before early in the fourth quarter, and success in the examination and approval, will be the major economies effectively cope with the next flu season in the northern hemisphere’s new outbreaks repeatedly provide vital protection, basic implementation that can ensure that relevant countries u-shaped recovery, thus the global economy may be in the whole year of 2020 to a better position to packaged.
However, if the corresponding R&D and approval cannot be completed until the end of the fourth quarter or early 2021, some economies may have a W-shaped recovery, or even an L-shaped recovery due to the structural damage of social economy caused by the long-term economic downturn.

The expected summer curbs on the spread of the virus have failed in many countries.
The fourth quarter is the last window of opportunity for 2020, with vaccines developed, approved and shipped around the world as quickly as possible.

According to several foreign media reports, security officials in the United States, the United Kingdom, and Canada claimed on Thursday that Russian cyber hackers are targeting organizations involved in the development of a coronavirus vaccine.

The news was first announced in a press release by the National Cyber ​​Security Center (NCSC) of the United Kingdom. In this announcement, the United Kingdom detailed the activities of the cyber threat organization called APT29, which believed that the organization manipulated and used the global Vaccine research and development institutions within the scope. The author has heard multiple reports of this incident in the BBC and VOA podcasts in the past two days.

NCSC stated that they are more than 95% certain that APT29 is part of the Russian Intelligence Agency. According to the NCSC’s assessment, this intelligence activity is most likely to collect information on COVID-19 vaccine research or research on the COVID-19 virus itself, which is 80% to 90%. NCSC claimed that “APT29’s malicious activities are still ongoing, mainly targeting government, diplomacy, think tanks, healthcare and energy targets in order to steal valuable intellectual property.”

The British Cyber ​​Security Center claimed that APT29 is also known as the “Duke” or “Comfort Bear” and is almost certainly operating as part of the Russian Intelligence Agency. The assessment was supported by partners from the Canadian Communications Security Agency (CSE), the United States Department of Homeland Security (DHS), the Cybersecurity Infrastructure Security Agency (CISA) and the National Security Agency (NSA), all of which are the Five Eyes Alliance One of the country members. In addition, according to U.S. media reports, this APT129 also participated in information fraud operations in the 2016 U.S. presidential election under other names.

British Foreign Secretary Dominique Raab said in a statement: It is totally unacceptable for Russian intelligence to target those who are committed to fighting the coronavirus pandemic. While other countries are pursuing their own self-interest with reckless behavior, Britain and its allies are continuing to work hard to find a vaccine to protect global health.

Coincidentally, the US authorities have been making similar accusations against China in recent months. FBI Director Chris Ray pretended last week: “At present, China is working hard to harm American medical institutions, pharmaceutical companies and academic institutions to conduct necessary COVID-19 research.

At present, the official Russian news agency completely denies this. How to treat this wave of British and American Five Eyes Alliance countries’ hype about the novel coronavirus vaccine cyber espionage against Russia and also piggybacking on China, and some opinions:

Thief shouts to catch thieves

According to the earliest revelations by former CIA employees Snowden and Assange, the United States has engaged in cyber theft and surveillance at all times, even its ally, German Chancellor Merkel. Most of the Internet networks and servers are in the United States. The United States has the most powerful network infrastructure. As the first country to establish a dedicated network command, the United States has the strongest cyber attack and protection capabilities in the world. Therefore, the United Kingdom and the United States and other five-eye alliance countries The possibility of a thief shouting and catching a thief is huge.

Maintain a high degree of vigilance and strengthen network protection

China was the first to suffer from the covid epidemic, the first to develop a covid vaccine and the progress was relatively fast. It is very important and necessary to strengthen network security protection and prevent other countries from stealing the intellectual property rights and patents of China’s covid vaccine through cyber espionage.

National groups are jealous and jealous

At a time when the covid epidemic is still raging, who is the first to develop and produce a covid vaccine will definitely attract attention. Recently, news about the development of a covid vaccine in China has been in the news from time to time. It is the so-called big draw, especially in the case of the overall failure of the United Kingdom, the United States and India to control the epidemic. Any psychology and anything may happen, and prevention should be done.

After China’s covid vaccine is successfully developed, it must “do a good job” and “say it well”

Combining the previous experience and lessons of anti-epidemic international cooperation and “mask diplomacy”, how to use and distribute China’s covid vaccine after R&D and production, how to balance between domestic and international, whether foreign aid is paid, how to spread, China should do it early Plans and preparations.

Russian state intelligence is breaking into international research centres racing to develop a vaccine for COVID-19, the UK and US and Canadian governments say.

It was unclear whether the research facility had been compromised or whether the vaccine project had been delayed by hacking, but officials warned that cyberattacks were continuing.

In a high-profile statement On Thursday, Britain’s National Cybersecurity Center said vaccine and treatment services in several countries had been targeted by a group called APT29 that was “almost certainly” part of Russia’s state intelligence service.
U.S. and Canadian security agencies later issued statements supporting the findings.

The British foreign secretary, Dominic Raab, said: “It is totally unacceptable that Russian intelligence has targeted people fighting coronavirus.”
“While other countries recklessly pursue their own self-interest, the UK and its Allies continue to work hard to find a vaccine to protect global health.”

The intelligence explosion comes at a geopolitically sensitive time, with US elections due in November and the global economy in recession.
The coronavirus has sparked a global vaccine race, and researchers in the UK have recently made progress.

In Moscow, President Vladimir Putin has hit a record low in his approval ratings as the Russian leader takes steps to ensure he stays in power until 2036.
Despite repeated allegations of interference, Russia has repeatedly denied the allegations.

Russia denies involvement in research into a vaccine against the coronavirus.
“We don’t know who broke into the drug companies and the research centers.
We can only say that Russia has nothing to do with these attempts, “Kremlin spokesman Dmitry Peskov told Bloomberg.

Kirill Dmitriev, chief executive of Russia’s sovereign wealth fund, which supports vaccine research, called the allegations “an attempt to discredit” Russia’s vaccine work.

But the NCSC said APT29 had targeted vaccine research and development organizations in the United States and Canada.
According to the report, malicious activity continues to target government, diplomatic, think tank, health and energy targets in order to steal valuable intellectual property.

Researchers have linked APT29 to Russian intelligence.
Carbon Black’s hacking activities have targeted dozens of governments, research institutions and companies around the world for more than a decade, according to an analysis published in March by the cyber security company Carbon Black.

In 2016, US cyber security company Crowdstrike linked APT29 to hacking of the Democratic National Committee.
In the summer of 2015, Russian hackers broke into democratic National Committee servers and maintained access to the group’s data for about a year, according to Crowdstrike researchers.

On the afternoon of July 10, the Joint prevention and control mechanism of the State Council held a press conference.
“Novel Coronavirus nucleic acid” was tested positive in the packaging sample of frozen South American white shrimp produced by an Ecuadorean enterprise recently, said Ms. Bi Kexin, director of import and Export Food Safety Bureau of the General Administration of Customs.
The test results showed that the container environment and package of the products of three enterprises in Ecuador were at risk of being contaminated by novel Coronavirus.

This is the third shock to the seafood industry following the virus and the “salmon incident” in southern China.
According to Fan Xubing, a seafood industry veteran, South American white shrimp accounts for 80 percent of the world’s farmed prawns. Ecuador and India are big exporters to China, and the incident will directly affect the white shrimp market.

A seafood industry analyst believes that three different brands of frozen South American white shrimp packaging found problems, the most likely is the safety exposure in the processing plant.
An immunologist also told Business Daily that the infection was probably related to seafood processing or transportation in Ecuador, “which is another wake-up call for cold-chain transportation.”

Ecuadorean processing plant may be exposed

Recently, customs across the country started novel Coronavirus monitoring for imported cold chain foods.
On the afternoon of July 10, Bixin introduced that on July 3, dalian Customs detected novel Coronavirus nucleic acid positive in one sample of the inner wall of the frozen South American white shrimp container manufactured by An Ecuadorian company and in three samples of the outer packing of the frozen South American white shrimp manufactured by an Ecuadorian company.
On the same day, xiamen Customs detected novel Coronavirus nucleic acid positive in two package samples of frozen South American white shrimp produced by an Ecuadorean enterprise.

An immunologist told NBD that the infection was probably related to seafood processing or transportation in Ecuador.
Infected with basic medical college of wuhan university school of medicine, professor, doctoral supervisor of Yang qiu said that the incident and Beijing xinfadi market salmon to detect the cutting board will be coronavirus similarities, at present the results of the survey is not released, cannot determine the specific viral infections, may and transportation, may also and seafood production factory.

Baidu’s real-time big data report on coVID-19 shows that as of the evening of July 10, 2020, Ecuador had 30,100 confirmed cases, 64,200 confirmed cases, 29,200 cured cases and 4,900 died.

One seafood insider said the most likely problem detected by each of the three different brands was a safety exposure to the processing plant.
Ecuador’s economy is relatively underdeveloped, the person said, and regulations may not be in place.
These three are far more than the many processing plants Ecuador has exported to China for South American white shrimp. The current proportion is not high, but the three cases of virus detection are independent of each other, which has raised concerns.

The incident is another wake-up call for the cold chain.
The above-mentioned immunological experts believe that for imported food, the focus should be on cold and frozen food testing, conditions allow, should be appropriate external packaging disinfection treatment.

Professional personage points out, the public should pay attention to the notification and announcement of relevant departments, to avoid contact and use will be coronavirus might pollution items and packaging, but don’t worry too much about, epidemic prevention and control into the normalized phase at present, domestic will be coronavirus detection means is already very mature, despite more than on imported seafood is random, but the customs department will certainly improve the sampling rate of focus on the products.

All parts of the white shrimp market will be collectively “brake”

After experiencing two impacts of “Salmon incident” in south China seafood market and new place, the domestic seafood market is in a very difficult situation.
Not long ago, a reporter from National Business Daily visited seafood markets in seven major cities and found that merchants were experiencing a sharp decline in trading volume and serious losses.

Some people in the seafood industry believe that this may be a shock to the seafood industry.
“The salmon case is something on the chopping board. Now it’s on the packaging. If the next step is shrimp or fish, it will be even worse.”
An industry insider expressed concern for reporters.

“I think people might brake at the same time.”
After the first two shocks, seafood importers, retailers and consumers are likely to act at the same time, Fan said.
With an attitude of “err on the side of kill”, the average consumer may not dare to buy imported frozen South American white shrimp in the short term, while the importer may still be unable to sell their previous stocks, and the decision to increase import will be more cautious.

The incident may affect Ecuador’s market share in China.
The Chinese embassy in the republic of Ecuador economic and commercial counsellor’s office said in a news release at the end of April this year, the urban aquaculture association (CNA), according to data in March 1, 2020, urban shrimp exports reached $908 million, up 12% from a year earlier, China, the United States and Spain for the first three largest export destination countries, exports at $510 million, $130 million and $070 million respectively, year-on-year growth of 59.4%, 18.2% and 75% respectively.
However, since the coVID-19 outbreak began in March, the export of Prawns to Asia in the first quarter of 2020 has only increased by 1% year-on-year, far lower than the 33% growth rate in the same period last year.

“As long as the global epidemic is not completely stopped, prevention and control should not be taken lightly, customs and other authorities should further strengthen testing and epidemic prevention measures, and can also sterilize the packaging of related products.”
“Yang said.

With regard to the products of three Ecuadorian factories found by Novel Coronavirus this time, the General Administration of Customs has decided to suspend the registration qualification of the above three enterprises in China from today, suspend the import and export of the products of the above three enterprises, and take measures such as returning and destruction of the temporarily detained goods.

Some imported seafood brands have begun to step up nucleic acid testing.
For example, The Canadian Arctic shrimp importer has been required to do nucleic acid testing and publish the report, Fan said. After that, the importer will start regular testing and provide testing reports every half a month. At the same time, the importer will remind the exporter to strengthen self-testing to ensure there is no hidden danger before export.

On August 8, it was reported that novel Coronavirus showed signs of rebirth in a sample of wastewater from Paris recently tested by researchers.
At the same time, novel Coronavirus infection rates have increased in some provinces in ile-de-France region, where Paris is located, but it is too early to judge a rebound from the epidemic.

According to the report, the researchers tested 12 samples of wastewater collected from June 22-25, among which 6 samples tested positive for traces of novel Coronavirus.
The researchers repeated the tests a week later, and the results were the same.

In mid-to-late April, a trace of novel Coronavirus was found in a non-drinking water system used to clean streets and water parks in Paris. Traces of novel Coronavirus were found in 4 of the 27 sampling points. Subsequently, the Municipal government of Paris shut down part of the water supply system.
Novel Coronavirus was not detected in the sampling conducted in mid-May, which is basically consistent with the trend of epidemic situation in France.

After the coVID-19 outbreak in France, local researchers continuously monitored the content of novel Coronavirus in the wastewater. By analyzing the samples collected from March 5 to April 23, the researchers found that the level of novel Coronavirus detected in the wastewater was correlated with the number of confirmed coVID-19 cases.

In a bulletin issued on 7 July, the French Academy of Medical Sciences recommended systematic monitoring of wastewater to better understand novel Coronavirus transmission.

At present, novel Coronavirus is not available and scientists around the world are redoubling their research and development efforts.

But the novel Coronavirus pandemic has been used by anti-vaccinators — a small group of people who don’t believe in vaccines — to spread misinformation on social media.
They say the vaccine will give you an electronic chip, poison you and make you sick.

A video called “Plandemic” has been streamed millions of times on YouTube and other streaming platforms claiming that the COVID-19 crisis is a government act.

Since the end of April, a list of substances, including some with scary names like phenoxyethanol and potassium chloride, has also been Shared thousands of times on Facebook, and it says that vaccines contain a lot of this toxic substance (which is not true, of course).

The anti-vaccine talk is not new, but it has gained widespread attention during the Novel Coronavirus pandemic, experts told AFP.

According to Sylvain Delouvee, a social psychology researcher at the University of Rennes, France, the anti-vaccine movement predates the Internet and the novel Coronavirus pandemics, but social media has created an effective “echo chamber” for anti-vaccinators.

He said anti-vaccine titles have proliferated despite the platforms’ claims that they will limit viral content.

He added that anti-vaccine rhetoric was “evolving without a clear definition”, meaning it could spread across political divides.

Some misleading claims – such as an article claiming that the substance used in vaccines and lethal injections contain the same toxic chemical – appear to have reappeared online without any direct mention of a novel Coronavirus.

According to David Broniatowski of George Washington University, Washington, D.C., it is unclear to what extent the novel Coronavirus pandemic has changed the range of misinformation.

“We are still investigating whether vaccine opponents have become more active because of the pandemic or whether they have become more visible because of the pandemic,” he said.

The attention from the novel Coronavirus has enabled anti-vaccinators to incorporate the message from the Novel Coronavirus into their existing anti-vaccine narrative, says Amelia Jamison of the University of Maryland.

“There is a small but vocal group of people online,” she said.
This outbreak has reinvigorated them.”

In the United States, she notes, anti-vaccines, anti-masks and anti-isolation movements have come together ostensibly to protect individual freedoms.

Anti-vaccinators “are taking up more and more space online,” Delouvee said, comparing the current wave of anti-vaccine activity to an “Internet tsunami.”

But Mr Jamison cautions that things are not always what they seem.

“If you look at the polarisation of vaccines, it’s often 50-50 [online].
But we know that in real life, it’s not even 50-50.”

According to the Annual Scientific and health survey, The Wellcome Global Monitor 2018, the vast majority of the world’s population (about 80 per cent) strongly or more or less agree that vaccines are safe.
Only 7 percent said they “somewhat or strongly disagree,” while 11 percent had no opinion.

Still, according to a study published in the scientific journal Nature, the anti-vaccine movement “may amplify” the novel Coronavirus epidemic just as it did the measles epidemic of 2019.

For its part, the World Health Organization has listed “indecision on vaccines” as one of the top 10 threats to global health in 2019.

In the past few months, the development of several strategies for vaccines has been moving forward. Wu Zunyou said that the results of the current phase 1 and 2 clinical trials are encouraging. By the end of the year, the application of vaccines will not be a big problem, but because of the ease of There are many people who feel that there is a need to be cautiously optimistic about the vaccine. The biggest problem is the production capacity and whether the vaccine has long-term immunity.

On July 3, a press conference on the COVID-19 epidemic was held in Beijing, during which a woman who had written a novel Coronavirus nucleic acid “positive” was reported in The Shijingshan Wanda Plaza on July 2.
According to the report, the 24-year-old woman had a history of contact with xinfa, had two negative nucleic acid tests, and was quarantined at home, during which she repeatedly damaged the magnetic door alarm and went out.
Again accept nucleic acid test, the result is positive, for asymptomatic infection.
By 14:00 on that day, 204 close contacts had been traced and placed under quarantine for medical observation, while other contacts were under further investigation and verification.

The sight of the woman squatting and crying when she learned of the nucleic acid test results triggered a lot of sympathy.
Can see the announcement in the woman “many times destroy the door magnetic alarm go out” when the plot, and let a lot of people mixed: so capricious careless, really should not.
This is not only bad for individuals, but also irresponsible for others.
At this time, we still have to fully realize that the virus cunning, more should always remain vigilant, do not give the virus any opportunity.

Although The number of newly confirmed local cases has been in the single digits for five consecutive days in Beijing, and the number of cured and discharged cases is also on the rise, this does not mean that the pressure of prevention and control in Beijing will be reduced.
In the face of the severe situation, only by strictly implementing epidemic prevention measures can we keep ahead of the epidemic.
For individual citizens, it means to do a good job of protection, isolate and seek medical treatment as required, and jointly build a line of defense against the epidemic.
Key personnel, in particular, should strictly abide by the reporting and quarantine rules and close the loopholes in epidemic prevention and control at their own level.

The confirmed woman has a history of exposure to new places, has had multiple nucleic acid tests, and has developed symptoms of discomfort, showing certain signs of risk.
At this time, what she needs to do is to strictly comply with the requirements of community epidemic prevention, do a good job of personal closed-loop management, and try not to go out when it is not necessary. She does have a need for medical treatment and must follow relevant procedures.
However, she repeatedly broke the door magnetic alarm, went out illegally without permission, and appeared in a large shopping mall only a few days after the release of home quarantine management without the results of the nucleic acid test, which put herself and others at risk.

What is more alarming is that this is not an isolated case.
In one case reported on July 1, a woman gathered and had dinner with several friends after she thought she had lived in isolation for 14 days. The result was positive nucleic acid test on June 30, which led to the isolation of close contacts and affected the prevention and control of the epidemic.
Moreover, during the period of self-isolation, the case had developed symptoms such as headache, vomiting and hypoolemia, but she did not report or seek medical treatment, which not only delayed her own treatment, but also magnified the risk of virus transmission.

In fact, the coVID-19 virus is far more subtle than we thought, and it is still possible to be diagnosed even if the requirement for isolation exceeds 14 days is met.
According to the circular, among the four confirmed cases in Beijing on June 26, solstice and 29, many of them were diagnosed more than 14 days after being quarantined, with a total of 28 cases.
This means that the idea that you can go out to parties and dinners after 14 days of isolation is dangerous. What you should do is continue to strengthen observation and avoid contact with people until the risk is completely resolved.

The pathogenesis of COVID-19 virus is complex, the characteristics of the disease need to be further studied, and the symptoms are diverse and atypical. There are still many unknown areas.
But because of this, the more can not be taken lightly, no matter ordinary people, or the key population, should do a good job of personal protection, pay attention to the health status, once the emergence of symptoms of discomfort should be fully protected timely medical treatment, not the slightest negligence.

The prevention and control of the epidemic requires a well-coordinated approach of mass prevention and control, and no link should be compromised.
Everyone is to blame, everyone is to blame.
As an important part of the four-way responsibility, individual responsibility requires every citizen to take the initiative, act actively, stick to the bottom line thinking, and fight a people’s war against the epidemic.
This includes both strict and meticulous self-protection and strict compliance with quarantine and treatment regulations.
In any case, we should not use our contempt and carelessness to affect the hard-won epidemic prevention and control situation.
