Onset characteristics
Coronavirus
According to the
existing case data, the new type of coronavirus pneumonia is mainly manifested
by fever, dry cough, fatigue, etc.
A small number of
patients are accompanied by nasal congestion, runny nose, diarrhea and other
upper respiratory and digestive tract symptoms. Severe cases usually have
difficulty breathing after 1 week, and severe cases rapidly progress to acute
respiratory distress syndrome, septic shock, difficult to correct metabolic
acidosis, coagulation dysfunction, and multiple organ failure.
It is worth noting that
severe and critically ill patients may have moderate to low fever during the
course of their illness, or even no obvious fever.
Mild patients only
manifested as low-grade fever, mild fatigue, etc., without pneumonia. Judging
from the status of the currently admitted cases, most patients have a good
prognosis, and a few patients are in critical condition.
The prognosis of the
elderly and those with chronic underlying diseases is poor. Symptoms in
children are relatively mild. Popular features
WHO Director-General
Tedros Adhanom Ghebreyesus said on March 11, 2020 that the new crown pneumonia
epidemic has become a pandemic.
Tedros said at a regular
press conference in Geneva that the spread and severity of the epidemic is
deeply worrying, "therefore, we estimate that the new crown pneumonia
epidemic has pandemic characteristics."
He said: "We have
never seen a pandemic caused by a coronavirus before. We have never seen a
pandemic under control before."
He emphasized that
describing the new crown pneumonia epidemic as a "pandemic" will not
change WHO's assessment of its threat, "it will not change what WHO is
doing, nor will it change what countries should do."
The new type of
coronavirus pneumonia is in the early stage of rapid change. China has
announced the complete genome sequence of the new coronavirus that causes the
new coronavirus pneumonia, which will help scientists and public health
organizations around the world to join in the research and development of
diagnostic reagents and the pathogenicity of the virus.
The National Health
Commission has issued Announcement No. 1 to include the pneumonia caused by the
new coronavirus in the Class B infectious diseases specified by the Infectious
Disease Prevention and Control Law, but adopts preventive and control measures
for Class A infectious diseases, and at the same time incorporates it into the
management of quarantine infectious diseases.
What is COVID Epidemic Level?
WHO's new coronary pneumonia situation report
On February 28, 2020, the WHO's daily report on the situation
of new coronary pneumonia showed that the regional and global risk levels were
raised to the highest level "very high", which is consistent with
China. The regional and global risk levels were previously "high".
On March 11, 2020 local time, the Director-General of the
World Health Organization Tan Desai announced that according to the assessment,
the WHO believes that the current new crown pneumonia epidemic can be called a
pandemic.
What is Coronavirus Transmission Method?
According to CCTV news, the Shanghai epidemic prevention and
control work conference introduced: Health and epidemic prevention experts
emphasized that the main routes of transmission of new coronary pneumonia that
can be determined are direct transmission, aerosol transmission and contact
transmission.
Direct transmission refers to the infection caused by the
patient's sneezing, coughing, talking droplets, and direct inhalation of the
exhaled gas; aerosol transmission refers to the droplets mixing in the air to
form aerosols, which cause infection after inhalation; contact transmission
refers to droplets are deposited on the surface of the object, and after
touching the contaminated hands, they then touch the mucous membranes of the
mouth, nasal cavity, eyes, etc., resulting in infection.
On June 14, 2021, Canadian researchers published a paper in
the British journal Nature Communications and found that the new coronavirus
can infect North American deer rats and spread among rats.
Rescue patients with new coronavirus pneumonia
The clinical manifestations of patients with pneumonia
infected by the new coronavirus are as follows: fever, fatigue, and dry cough
are the main manifestations. Upper respiratory symptoms such as nasal
congestion and runny nose are rare, and hypoxia and hypoxia may occur.
About half of the patients have difficulty breathing more
than a week later. In severe cases, they rapidly progress to acute respiratory
distress syndrome, septic shock, difficult to correct metabolic acidosis, and
coagulation dysfunction.
It is worth noting that severe and critically ill patients
may have moderate to low fever during the course of their illness, or even no
obvious fever. Some patients have mild onset symptoms, but no fever, and
usually recover after 1 week. Most patients have a good prognosis, and a few
patients are critically ill and even die.
What is Coronavirus Treatment Technique?
The eight anti-epidemic scientific and technological commando
teams are patient prevention detection and diagnosis detection technology, ultra-sensitive
quantitative PCR kit technology, antibody drugs and vaccines, indoor and
building air disinfection technology, protein-based virus transmission
blockers, and stem cells Inflammation treatment drugs, epidemiological research
and psychological rehabilitation systems.
What is Coronavirus Diagnosis and Treatment Plan?
After the outbreak of new coronavirus-infected pneumonia, the
National Health Commission issued the "New Coronavirus Pneumonia Diagnosis
and Treatment Plan", and through the analysis of the epidemic situation
and research progress, the basis for organizing experts to analyze, judge and
summarize the preliminary medical treatment work The diagnosis and treatment
plan was revised in time.
On January 16, 2020, the "Diagnosis and Treatment Plan
for Pneumonia Infected by New Coronavirus (Trial)" was released.
The "Diagnosis and Treatment Plan for Pneumonia of New
Coronavirus Infection (Trial Version 2)" was also released subsequently.
On January 22, 2020, the General Office of the National
Health Commission and the Office of the State Administration of Traditional
Chinese Medicine issued the "Diagnosis and Treatment Plan for Pneumonia
Infected by the Novel Coronavirus (Trial Version 3)".
On January 27, 2020, the General Office of the National
Health Commission and the Office of the State Administration of Traditional
Chinese Medicine issued the "Diagnosis and Treatment Plan for Pneumonia
Infected by the Novel Coronavirus (Trial Version 4)".
On February 4, 2020, the General Office of the National
Health Commission and the Office of the State Administration of Traditional
Chinese Medicine jointly issued the "Diagnosis and Treatment Plan for
Pneumonia Infected by the Novel Coronavirus (Trial Version 5)".
On February 8, the General Office of the National Health
Commission and the Office of the State Administration of Traditional Chinese
Medicine issued the "New Coronavirus Pneumonia Diagnosis and Treatment
Plan (Trial Fifth Edition Revised Edition)".
On February 14, 2020, the General Office of the National
Health Commission and the Office of the State Administration of Traditional
Chinese Medicine jointly issued the "Diagnosis and Treatment Plan for
Severe and Critical Cases of Novel Coronavirus Pneumonia (Trial Version
2)".
On February 19, 2020, the General Office of the National
Health Commission and the Office of the State Administration of Traditional
Chinese Medicine jointly issued the "New Coronavirus Pneumonia Diagnosis
and Treatment Plan (Trial Sixth Edition)".
On March 4, 2020, the General Office of the National Health
Commission and the Office of the State Administration of Traditional Chinese
Medicine jointly issued the "New Coronavirus Pneumonia Diagnosis and
Treatment Plan (Trial Version 7)".
On August 18, 2020, the General Office of the National Health
Commission and the Office of the State Administration of Traditional Chinese
Medicine jointly issued the "New Coronavirus Pneumonia Diagnosis and
Treatment Plan (Trial Eighth Edition)".
What is COVID-19 Discharge Standard?
On January 28, 2020, the National Health Commission notified
the discharge criteria: the clinical symptoms are relieved, the body
temperature is normal, and the two nucleic acid tests are negative to ensure
that the discharge is not contagious.
The discharge standard is that the throat swab is negative
twice, there are no symptoms, the body temperature is normal, and the CT is
normal. After that, he will be isolated for another two weeks.
If the anal swab
is required to be normal, the patient will be overstocked and the bed will not
be able to turn around. Therefore, it is still necessary to observe closely and
carry out a hierarchical management of all patients.
Vaccine development
On December 31, 2020, the State Council’s joint prevention
and control mechanism announced that Sinopharm’s China Bio-New Crown
Inactivated Vaccine has been approved by the State Food and Drug Administration
for conditional listing.
Guarantee Notification
On January 24, 2020, the General Administration of Customs
and the National Health Commission issued the "Announcement on the
Prevention and Control of Pneumonia Infected by the Novel Coronavirus":
1. If entry and exit personnel have fever, cough, or
breathing difficulties when exiting or entering the country , Should
proactively declare to the customs and cooperate with the customs to do health
and quarantine work such as body temperature monitoring, medical inspections,
and medical investigations.
2. If an entry-exit person develops fever, cough, difficulty
breathing and other uncomfortable symptoms during the operation of the
transport, he must promptly inform the crew of the transport. The person in
charge of the transport should provide passengers with personal protective
equipment and report to the customs at the port of entry and exit in time.
3. Entry-exit personnel should maintain good personal hygiene
during travel, such as washing hands frequently, wearing masks, avoiding close
contact with patients with acute respiratory infections, etc.
If fever is
accompanied by coughing, breathing difficulties and other symptoms of acute respiratory
infections, they should immediately Seek medical attention and explain the
recent travel history to the doctor.
4. Entry personnel can follow the official website of the
National Health Commission of the People's Republic of China for the latest health
information. If they have relevant symptoms, they should seek medical attention
immediately and explain their recent travel history to the doctor.
5. The customs will dynamically adjust port prevention and
control measures in real time based on the progress of the epidemic.
On February 3, 2020, the Central State Organs Housing Fund
Management Center issued the "Notice on Cooperating with the Epidemic
Prevention and Control Work and Strengthening the Service Guarantee of the
Housing Provident Fund for Central State Organs."
The "Notice" lists the pneumonia caused by the new
coronavirus in the scope of housing provident fund for serious illness.
Patients can withdraw their own housing provident fund for medical expenses,
wholesale and retail, accommodation and catering, logistics and transportation,
cultural tourism and other industries that are affected by the epidemic and
make production and operation difficult.
The enterprise may
also apply for the suspension of the payment of the housing provident fund in
accordance with the regulations, and resume the payment after the company’s
benefits improve.
On February 20, 2020, at the press conference of the Joint
Prevention and Control Mechanism of the State Council, Xiong Xianjun, Director
of the Medical Management Department of the National Medical Insurance
Administration stated that in order to ensure that patients will not be
affected by cost issues and that treatment hospitals will not affect treatment
due to payment policies.
The National Health Insurance Bureau in conjunction
with relevant departments, a fee reduction policy has been established for the
special group of confirmed and suspected patients with new coronary pneumonia
to provide protection for the prevention and control of the epidemic.
On March 30, 2020, I interviewed Xiong Xianjun, a comrade in
charge of the Medical Service Management Department of the National Medical
Insurance Administration, and learned that as of March 15, 31 provinces
(autonomous regions, municipalities) and Xinjiang Production and Construction
Corps reported that the country’s new coronary pneumonia has been diagnosed and
suspected.
The medical insurance settlement was 93,238 person-times (including
multiple outpatient visits and settlements), involving a total cost of 1.039.6
million yuan, and the medical insurance system paid a total of 67.734 million
yuan.
The number of confirmed patients nationwide was 44,189, involving a total
cost of 750.48 million yuan and a per capita cost of 17,000 yuan, of which the
medical insurance payment ratio was about 65% (the remaining part was
subsidized by the finance).
On December 28, 2020, the "National Basic Medical
Insurance, Work Injury Insurance and Maternity Insurance Drug Catalog
(2020)" was announced. In this adjustment, great importance is attached to
the protection of drugs related to the treatment of new coronary pneumonia, and
drugs such as ribavirin injection and arbidol granules have been added to the
catalog.
The drugs listed in the latest version of the national new
coronary pneumonia diagnosis and treatment plan have all been included in the
national medical insurance. Catalogue, with practical actions to help prevent
and control the epidemic.
Name Confirmation
At a press conference held on the afternoon of February 8,
2020, the spokesperson of the National Health Commission stated that the new
coronavirus-infected pneumonia was temporarily named Novel coronavirus
pneumonia (Novel coronavirus pneumonia), referred to as New Coronary Pneumonia
(NCP).
The official name of the new coronavirus was announced by the
WHO on Twitter
The Director-General of the World Health Organization Tan
Desai announced on February 11, 2020 that the new type of coronavirus-infected
pneumonia will be named "COVID-19" (Corona Virus Disease 2019), and
the Chinese translation is "Covid-19".
The name is interpreted as: CO stands for Corona, VI stands for
Virus, D stands for Disease, 19 is due to the outbreak of the disease in 2019.
At the same time, the International Virus Classification Committee declared
that the new type of coronavirus was named "SARS-CoV-2" (Severe Acute
Respiratory Syndrome Coronavirus 2); and that this virus was a sister virus of
SARS coronavirus.
On February 22, 2020, the official website of the National
Health Commission issued a notice, deciding to revise the English name of
"new coronavirus pneumonia" to "COVID-19", which is
consistent with the name of the World Health Organization, and the Chinese name
remains unchanged.
Control Type
In February 2020, the National Health Commission announced on
No. 1 that pneumonia caused by the new coronavirus will be included in the
Class B infectious diseases specified in the "Law of the People's Republic
of China on the Prevention and Control of Infectious Diseases", and
measures to prevent and control Class A infectious diseases will be taken.
Expert Opinion
On February 10, 2020, Zhang Dingyu, then deputy secretary of
the Party Committee and Dean of Wuhan Jinyintan Hospital, introduced that new
coronary pneumonia is actually a self-limiting disease. The vast majority of
patients, including severe and critically ill patients, can be discharged
smoothly after various oxygen therapy, symptomatic treatment and
immunomodulatory treatments.

Internationality
Cumulative confirmed cases of new coronavirus pneumonia
On March 25, 2020, WTO Director-General Azevedo said that the
epidemic will have a huge impact on the global economy.
He said: “Recent forecasts
show that there will be an economic downturn and mass unemployment (globally),
which will be more serious than the financial crisis twelve years ago.”
Affected by the new crown pneumonia epidemic, the economies of many countries
have already experienced a decline.
Restrictive measures introduced to slow the spread of the
epidemic have hit the physical industry hard, and a large number of employees
are facing unemployment. The Director-General of the WTO called on all
countries to maintain open trade and jointly fight the epidemic.
According to real-time statistics released by worldometer,
which has been tracking the global new crown pneumonia epidemic data, as of
7:00 on January 26, 2021, Beijing time, the cumulative number of confirmed
cases of new crown pneumonia worldwide has exceeded 100 million, reaching
100,203,700, and the cumulative number of deaths has exceeded 214.
10,000 cases, reaching 2147411 cases. However, according to
the latest statistics of the new crown epidemic released by Johns Hopkins
University in the United States, the cumulative number of confirmed cases in
the world has not reached 100 million, 995,87084, and 2,136,559 deaths.
On May 12, 2021, the World Health Organization's independent
team on COVID-19 pandemic preparedness and response released its latest report.
The report shows that it is estimated that by the end of 2021, the new crown
epidemic will cause a loss of 10 trillion US dollars to the world. In 2020, at
least 17,000 medical workers worldwide will die from the new crown.
Virus Research Difference study
On March 3, 2020, a research paper on "Preprints with
The Lancet" was published on the preprint server and the early research
platform SSRN. The Wuhan University People’s Hospital team analyzed the spread
of the new coronavirus among women for the first time The particularity that
may exist in.
Coronavirus Rendering
Studies have shown for the first time that women show
different characteristics from men in the spread of COVID-19. Women not only
have relatively mild symptoms, but also have a longer incubation period than
men. This may be because women are born with stronger antiviral properties than
men. Immunity.
During the screening process, no matter whether the women
have symptoms or not, as long as the contact history is clear, they should be
tested for nucleic acid, and the isolation period for women under medical
observation should also exceed 14 days.
The study found
In March 2020, the latest research by Professor Tong Shilu
from the National Children’s Medical Center (Shanghai) and Shanghai Children’s
Medical Center affiliated to Shanghai Jiaotong University School of Medicine
found that children of all ages are sensitive to COVID-19, and there is no
obvious Gender differences.
On March 30, 2021, the China-WHO Joint Research Report on the
Traceability of the New Coronavirus was released in Geneva. According to the
report, many early cases in Wuhan were related to the South China Seafood
Market, but there were also cases related to other markets. This showed that
the South China Seafood Market was not the original source of the new crown
virus, and it is not yet clear how the virus spread to the South China market.
Based on the existing scientific evidence and findings, the
joint expert team conducted a qualitative risk assessment on the possibility of
the introduction of the new coronavirus into the four human transmission
routes, and used "very unlikely", "impossible",
"probable", "more likely" and "very likely". 5
levels of evaluation.
The report believes that the new coronavirus is
"probably to more likely" to be transmitted directly from the
original animal host, "more likely to very likely" to be introduced
into humans via an intermediate host, "probably" to be transmitted to
humans through cold chain food, and "very unlikely" to be transmitted
to humans through laboratory events.
In order to detect and confirm early cases of COVID-19, the
Epidemiology Working Group evaluated the surveillance data on the incidence of
respiratory diseases in Wuhan and surrounding areas at the end of 2019. In all
these studies, there is no evidence that the incidence of respiratory diseases
in the months before the outbreak of the new crown is affected by the new crown
virus.
The Molecular Traceability Working Group analyzed the genome
data of viruses collected from animals. Evidence has shown that the coronavirus
that is closest to the new coronavirus is present in bats and pangolins,
indicating that these two mammals may be the host of the new coronavirus, but
the similarity of the virus is not enough to make it the direct ancestor of the
new coronavirus.
In addition, animals such as mink and cats are highly
susceptible to the new coronavirus, indicating that there may be other animals
as potential hosts.
The Animal and Environment Working Group did not find the
presence of the new coronavirus in the sampling and testing of wild animals in
China.
The Animal and Environment Working Group analyzed the coronaviruses that
are related to the new coronavirus found in animals such as chrysanthemum bats
and pangolins.
In more than 80,000 samples of wild animals, livestock and
poultry collected from 31 provinces, regions and cities in China before and
after the outbreak, no positive results of antibodies or nucleic acids to the
new coronavirus were detected.
On June 15, 2021, the Voice of America radio website reported
that according to a new study by the U.S. government, the new coronavirus
already existed in the U.S. in December 2019, a few weeks before health
officials first detected the infection.
A team including researchers from the National Institutes of
Health (NIH) conducted a study that analyzed 24,000 blood samples. Their
findings show that some Americans were infected with the new crown virus as
early as mid-December 2019, a few weeks before the world recognized the
outbreak of a new deadly virus in the Chinese city of Wuhan.
On July 14, 2021, the international authoritative scientific
journal "Nature" published a study stating that scientists have
discovered a kind of "super antibody" that can not only fight against
a variety of new coronavirus variants, but also against other closely related
strains. Related to the coronavirus, this new discovery may help develop a
wider range of vaccines and treatments.
According to a paper published in the journal Nature, the
main author of the study is the Fred Hutchinson Cancer Research Center (Fred
Hutchinson Cancer) in Seattle, USA. The study found that one of the
neutralizing antibodies named "S2H97" can target and attach to the viral
receptor binding domains listed in all experiments.
Starr said, "It is called the coolest antibody ".
The team's further research on "S2H97" showed that it can find a
previously invisible and well-hidden area on the virus binding domain, and only
when it binds to human cell receptors will it eject from the binding domain,
and then neutralize it.
It functions to prevent the spread of the virus, which
is why this "super antibody" S2H97 can widely fight the new coronary
pneumonia and SARS and other viruses under the B-coronavirus branch B.
Mourning Activity
In order to express the deep condolences of the people of all
ethnic groups across the country for the sacrifice of martyrs and compatriots
who died in the fight against the new crown pneumonia epidemic, the State
Council decided to hold a national mourning event on April 4, 2020.
During this period, the national and foreign embassies and
consulates lowered their flags to mourn, and public entertainment activities
were suspended throughout the country.
Starting at 10 o'clock on April 4, people across the country
observed a three-minute silence. Cars, trains, and ships sounded their horns,
and air defense sirens sounded.
America
On June 14, 2021, U.S. congressmen mourned the death of
approximately 600,000 U.S. COVID-19 patients outside the Capitol in Washington.
List of Coronavirus Experts
On September 3, 2020, the co-chair of the WHO Expert Group on
Response and Evaluation of the New Coronary Pneumonia Epidemic announced the
list of members of the expert group at a briefing by member states.
Zhong
Nanshan, academician of the Chinese Academy of Engineering and director of the
Guangzhou Institute of Respiratory Diseases, was selected.
