Has the novel coronavirus pneumonia become a global epidemic?

The novel coronavirus (2019-NCOV), discovered as a result of the 2019 Wuhan viral pneumonia case, was named by the World Health Organization on January 12, 2020. Coronaviruses are a large family of viruses. The novel coronavirus is a new strain of coronavirus that has never been detected in humans before.

But has the novel coronavirus pneumonia really become a global epidemic?

On January 30, 2020, the World Health Organization (WHO) declared the novel coronavirus outbreak a public health emergency of international concern. The incubation period is 1-14 days, and most of them are 3-7 days. The incubation period is contagious, and asymptomatic infected people can also be a source of infection.

Transmission is through respiratory droplets and contact, with aerosols being the main route of transmission. It is necessary to strengthen the isolation and management of susceptible people and sick people. The first case of novel coronavirus pneumonia was found in Wuhan City, Hubei Province, and most of the patients had a history of exposure or family gatherings at the Huanan Seafood Market, which is behind the scenes of illegal wildlife sales, and law enforcement officials have dealt with them immediately after the incident.

Researchers also took samples of the virus, which is found in wild animals, at the Huanan Seafood Market.

Because the outbreak of the virus was just in time for the New Year, the population of Wuhan flowed to all parts of the country through the Spring Festival, and the virus spread on various means of transportation, resulting in the spread of the virus from Wuhan to all provinces and cities across the country and even abroad, and patients were also found in Japan and South Korea, because the virus can be transmitted through respiratory droplets and aerosols, which has led to the national mask being out of stock, and hospital supplies are not available. However, many factories have been stepping up the production of disinfectant, masks and other items, and have gathered the strength of the whole country to raise donations and materials, and have built two hospitals of Vulcan and Thor to accommodate patients.

The new coronavirus pneumonia has not yet become a "global epidemic", early detection, early isolation, we have taken the most effective measures, plus there are countless medical staff and researchers are struggling on the front line, now the epidemic situation has gradually improved, against the epidemic, we are united, Wuhan come on, China come on.

Of course, judging from its current development rate, it is already a very strong virus. It spreads very quickly. It has led to the corresponding symptoms in other countries.

Now it has become a global epidemic, but China accounts for a lot of the number of confirmed cases, while other countries account for only a small part.

The novel coronavirus pneumonia has not yet become a global epidemic, it is only a large-scale spread in China, and only a few abroad. I believe that China will be able to win.

No, most of the cases are infected, not the body itself, as long as it can be well controlled, the number of cases will be greatly reduced, and the disease will slowly disappear.

It's not a global pandemic. **Strong measures have been taken to stop the spread of the epidemic, and the most important thing at this stage is "early detection, early isolation." ”

The main measures taken by China include joint prevention and control, early detection, early isolation**. Since the outbreak of the new crown pneumonia epidemic, China** has taken the most comprehensive, strictest and most thorough prevention and control measures to resolutely fight the epidemic in a highly responsible attitude towards the life safety and health of the Chinese people and the people of the world. As a result of hard work, the epidemic prevention and control situation in China has continued to improve, and the recovery of production and life order has accelerated.

Legal basis: Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases

Article 40 When disease prevention and control institutions discover the epidemic situation of infectious diseases or receive reports of the epidemic situation of infectious diseases, they shall take the following measures in a timely manner: (1) Conduct epidemiological investigation of the epidemic situation of infectious diseases, put forward suggestions for the demarcation of epidemic points and epidemic areas according to the investigation situation, carry out sanitary treatment of contaminated places, conduct medical observation and take other necessary preventive measures for close contacts in designated places, and propose epidemic control plans to the health administrative departments. Carry out sanitary treatment in epidemic areas, propose epidemic control plans to the health administrative departments, and take measures in accordance with the requirements of the health administrative departments: (3) Guide lower-level disease prevention and control institutions to implement measures for the prevention and control of infectious diseases, and organize and guide relevant units in handling the epidemic situation of infectious diseases.

Article 41: For persons in places where cases of Class A infectious diseases have already occurred or in specific areas within the premises, the local people** at or above the county level where they are located may implement isolation measures, and at the same time report to the people** at the next higher level; The people at the higher level who receive the report shall immediately make a decision on whether to approve it. Where higher-level people** make a decision not to approve it, the people** who are implementing the isolation measures shall immediately lift the isolation measures.

From the introduction of the "20 Measures" and the "New 10 Measures" optimization measures, to the renaming of the new coronary buried virus pneumonia as the new coronavirus infection, and then to the formal adjustment from "Category B and A" to "Category B and B" ......China's new crown epidemic prevention and control has taken the initiative to make a series of major adjustments.

In the face of the uncertainty of the epidemic situation, China has always adhered to the principle of putting people and lives first, insisting on seeking truth from facts and respecting science, and constantly optimizing and improving prevention and control measures according to the time and situation, so as to confront the virus with the stability of the prevention and control strategy and the flexibility of the prevention and control measures, so as to win valuable time and the greatest space for a smooth transition in the fight against the epidemic.

With scientific decision-making in response to the time and situation, China's epidemic prevention and control has entered a new stage.

The outbreak in Wuhan began in December 2019.

The outbreak of the epidemic in Wuhan began on December 27, 2019, and since the beginning of the epidemic, it can be divided into several stages: the first stage: rapid response to the sudden outbreak (December 27, 2019 to January 19, 2020) Wuhan City, Hubei Province, monitored and found a case of pneumonia of unknown cause, China reported the epidemic as soon as possible, took swift action, and carried out ** scientific and epidemiological investigations.

Phase 2: Initial containment of the spread of the epidemic (January 20 to February 20) With the rapid increase in new confirmed cases across the country, China has taken a key measure to stop the spread of the virus, resolutely and decisively closing the passage from Han to Hubei, and the battle to defend Wuhan and Hubei has been launched in an all-round way.

In the third stage, decisive results were achieved in the defense of Wuhan and Hubei (March 18 to April 28), with Wuhan as the main battlefield, the spread of the local epidemic in the whole country was basically blocked, the control measures for the passage from Han to Hubei were lifted, and the number of patients in Wuhan was cleared.

Novel coronavirus pneumonia

Novel coronavirus pneumonia, referred to as "new crown pneumonia", named by the World Health Organization as "2019 crown lachizovirus disease", is a pneumonia caused by the 2019 novel coronavirus infection. Since December 2019, some hospitals in Wuhan, Hubei Province, have successively found a number of cases of pneumonia of unknown cause with a history of exposure to the Huanan seafood market, which are confirmed to be acute respiratory infections caused by 2019 novel coronavirus infection.

According to the available case data, the main manifestations of novel coronavirus pneumonia are fever, dry cough, fatigue, etc., and a small number of patients are accompanied by upper respiratory and digestive tract symptoms such as nasal congestion, runny nose, and diarrhea. Severe cases often develop dyspnea after 1 week, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, coagulation dysfunction, and multi-organ failure.

The above content is referenced from Encyclopedia - Novel Coronavirus Pneumonia.

Novel coronavirus pneumonia is referred to as new crown pneumonia, which is an acute respiratory infectious disease caused by the new coronavirus, and the cells infected by the new coronavirus, mainly the cells of the lungs, are infected through the respiratory tract, and the new coronavirus is highly virulent and causes a very strong inflammatory reaction, so it is easy to lead to pathological lung inflammation, that is, pneumonia.

Pneumonia caused by the new coronavirus, you ask me and answer - disease cognition

What is the novel coronavirus?

Coronaviruses are a large group of viruses that are known to cause illness in patients with clinical symptoms ranging from the common cold to severe pulmonary infections, such as Middle East Respiratory Syndrome (MERS) and SARS. The novel coronavirus discovered in Wuhan this time is a new type of coronavirus that has not been detected in humans before.

What are the characteristics of the novel coronavirus?

The novel coronavirus is sensitive to ultraviolet light and heat, and lipid solvents such as 56 degrees Celsius for 30 minutes, ether, 75 ethanol, chlorine-containing disinfectants, peracetic acid, and chloroform can effectively inactivate the virus.

How does the novel coronavirus spread?

Based on current evidence, it can be determined that the novel coronavirus can continue to transmit from person to person. At present, the identified transmission routes are mainly through respiratory droplets and contact, and aerosol and fecal-oral transmission routes have yet to be clarified.

What are the symptoms of the novel coronavirus that require medical attention?

Seek medical attention if you have suspicious symptoms (fever, cough, sore throat, chest tightness, dyspnea, fatigue, nausea and vomiting, diarrhoea, conjunctivitis, muscle aches, etc.) and if you have a history of epidemic in areas with a high incidence of the epidemic, or if you have a history of close contact with suspected or confirmed cases.

What should I do if I suspect I have the new coronavirus?

If you suspect that you are infected with the new coronavirus, first of all, do not go to crowded places, wear masks, keep a good distance from your family, pay attention to ventilation, pay attention to personal hygiene, and go to the fever clinic of the nearest designated hospital. During the consultation, the doctor took the initiative to tell the doctor who he had come into contact with, and cooperated with the doctor to carry out an investigation.

Is it OK to have COVID-19?

There have been some patients, with the active efforts of doctors, who have overcome the new coronavirus and finally achieved the goal.

Can banyan root and smoked vinegar prevent novel coronavirus pneumonia?

It is suitable for the treatment of feverish diseases such as wind-heat, cold, etc., and has no effect on coronavirus. Smoked vinegar does not achieve the disinfection effect.

Can antibiotics ** COVID-19?

Antibiotics are used for bacterial infection, the pathogen of new coronavirus pneumonia belongs to the virus, taking antibiotics not only has no preventive and ** effect, but may cause adverse drug reactions, and even destroy the normal intestinal flora.

How to maintain a good attitude in the face of the epidemic?

Coping with stress: In critical situations, it's normal to feel sad, nervous, restless, confused, scared, or irritable. It can be helpful to talk to someone you trust. Communicate with your family and friends.

Get the truth: Gather information that will help you accurately determine your risk so you can take reasonable precautions. Refer to trustworthy sources, such as the World Health Organization's official or national or local public health authorities.

On February 11, World Health Organization Director-General Tedros Adhanom Ghebreyesus announced that the pneumonia caused by the novel coronavirus will be officially named "coronavirus disease 2019" (COVID-19).

Among them, "co" stands for corona, "vi" stands for virus, "d" stands for disease, and "19" stands for the year the disease was discovered in 2019.

At the same time, the coronavirus was named "SARS-CoV-2" because of its high affinity with the coronavirus that caused SARS.

It's important to have a name to prevent people from using other names that are inaccurate or stigmatized. "We wanted an oak name that didn't allude to any location, animal, person or crowd." ”

This strange symptom is often seen online. For example, some people often fart, some people are very good at eating, some people are suddenly very active in learning, and so on. It's just that everyone's physique is different and their reactions are different.

Among patients with new coronavirus infection, some patients have mild symptoms such as dry cough and fever, and about 10% to 20% of patients will develop pneumonia and other symptoms.

We can speculate as to why this discrepancy is caused by the following:

1.Immune system differences. The human body can resist the invasion of viruses through innate immune responses and adaptive immune responses, and both strong and weak immune responses can cause immune system dysregulation and affect the body's health.

However, there are differences in the strength of the immune system of different people, and in the elderly and immunodeficient patients, the body's immune response is relatively weak, and the ability to kill viruses is also weak, which may be more likely to cause tissue infections and organ failure. Young adults, on the other hand, have a more robust immune system and can clear the virus more quickly, so they only show mild symptoms.

In a recent outbreak of infection, an analysis of 99 cases of infection with the novel coronavirus found that 50 patients had underlying chronic diseases such as cardiovascular diseases, endocrine system diseases, and digestive system diseases, accounting for about 51%, which may have weakened the patient's immunophysiological system and made the infection more likely to occur.

2.Individual genetic differences may result in different populations having different susceptibility to the virus. At present, it has been found that the expression of genes encoding viral receptor proteins is different in the population, which may lead to different susceptibility of different individuals to the virus.

3.Physiological differences result in differences in the susceptibility of the lower respiratory tract and lungs to the virus. The cell-sensitive state blindness of viruses causes tissue differences in the responses they infect humans, resulting in different clinical symptoms.

The distribution of susceptible cells in the body disturbance will be different in each person, and if some patients have more susceptible cells in the lower respiratory tract or lungs, they are more likely to cause severe pneumonia.

So as long as we have such a correct understanding, we will not be entangled in these strange problems.
