Where did the epidemic come out and how did it come about?

1. Animals say. The theory is that the coronavirus.

Originated in nature, it may have been transmitted to humans by some animal.

2. Artificial. According to this view, the new coronavirus originated in a virus laboratory and was leaked or deliberately introduced into a country by a laboratory.

From December 19, 2019.

The outbreak of this epidemic has caught many places off guard, if the knowledge reserve is insufficient, the work is not solid and meticulous, and the lack of facing emergencies.

The rapid response will inevitably lead to a reactive response mode, which is in great contrast to the high expectations placed on the people.

You must know that the sudden epidemic and the medical unknown of the epidemic will cause the people's social psychology to be particularly fragile and sensitive. Any work mistakes, irregularities, and inaction will immediately become the object of criticism.

As for the origin of the epidemic, at the earliest time, everyone thought that it was the Huanan Seafood Market, because many patients were related to the seafood market. However, at the end of February, Academician Zhong Nanshan pointed out that the outbreak of the epidemic in China does not mean that China is the origin of the virus. So where did the new coronavirus come from?

According to the current research progress, the earliest origin and final ** of the new coronavirus have never been clarified. The outbreak first appeared in China, but it did not necessarily originate in China. There are various indications that the United States is the most suspicious in the discussion of experts from various countries, but there is no conclusive evidence, so it is still inconclusive.

The outbreak of the epidemic in a restaurant in Wuhan caused the whole of Wuhan to be locked down overnight to pay tribute to medical workers.

It is said to have appeared for the first time in the U.S. Navy.

The cause is unknown.

Since December 2019, Wuhan has continued to carry out surveillance of influenza and related diseases, and 27 cases of viral pneumonia have been found, all of which were diagnosed as viral pneumonia and lung infection. Of the 27 cases, 7 are in critical condition, the rest are in manageable condition, and 2 are in improved condition and are scheduled to be discharged from hospital in the near future.

The investigation found that most of the pneumonia cases were operators of Huanan Seafood City. As of December 31, 2019, relevant virus typing testing, isolation**, public opinion control, terminal disinfection and other work are ongoing.

The Wuhan Municipal Health Commission has learned that a number of pneumonia cases recently found in some medical institutions are related to Huanan Seafood City.

The source of the epidemic is still nature, but it is still unclear which country or region of the world it is from.

When the outbreak of the epidemic in China began, the world blamed China, but with the passage of time and the progress of epidemic investigation around the world, it was later found that as of mid-January 2020, the United States had already been infected with the new coronavirus, which can be imagined earlier than the outbreak of the epidemic in China.

Later, according to the Italian newspaper La Repubblica** on January 11, 2020, as of November 10, 2019, an international research team led by the University of Milan in Italy found the genetic sequence of the new coronavirus in the biopsy sample of a 25-year-old female patient with symptoms of **inflammation.

However, the epidemic is still very serious around the world, and it is not clear whether in fact anyone will actually be infected with the new coronavirus earlier.

According to an interview with reporters, on February 27, 2020, Academician Zhong Nanshan also said in an interview with reporters: There is a clue that bats in Zhoushan, Zhejiang carry viruses, and pangolins also have a high degree of homology, and Guangxi bats may also have a relationship, but how the new crown virus came about, it is still unclear, and I don't believe that there are only pangolins in the middle host, there should be others.

Each province, city, and county will have an epidemic prevention and control headquarters, and the specific department for the implementation of epidemic isolation is the city, county, and district disease control and prevention center. The Center for Disease Control and Prevention mainly carries out disease prevention and control, emergency response to public health emergencies, environmental and occupational health, nutrition and health, aging health, maternal and child health, radiation health and school health; Organize the formulation of national public health technical programs and guidelines, and undertake the comprehensive management of public health-related health standards; Carry out monitoring of infectious diseases, chronic diseases, occupational diseases, endemic diseases, public health emergencies and suspected abnormal reactions to vaccination, as well as monitoring and evaluation of national health status; Participate in national public health emergency preparedness and response, and organize the formulation of technical specifications related to epidemiological investigation and sanitary treatment of food safety accidents; Carry out disease prevention and control, public health emergency response, public health key scientific research and technology development; Carry out postgraduate education, continuing education and related professional and technical training in the field of public health.

An epidemic means the occurrence and spread of an epidemic. Epidemic is a form and sound and a meaning word, 疒 (nè) is the form, service (omitted 彳) is the sound, service also means, service refers to military service, labor service, epidemic refers to the disease of the person who serves, that is, infectious disease.

The "2019 novel coronavirus" was discovered as a case of viral pneumonia in Wuhan in 2019, and was named by the World Health Organization on January 12, 2020. Coronaviruses are a large family of viruses known to cause colds as well as more severe illnesses such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus is a new strain of coronavirus that has never been detected in humans before.

Wait a minute, you. I'm sorting it out for you. Wait a minute

Can you send a screenshot of it?

A: City names marked with * (asterisk) indicate that there are currently medium or high-risk areas in the city you have visited in the past 14 days, but this does not mean that you have actually visited these medium- and high-risk areas. 1.

Instead of marking cities with medium and high risk areas in red, trip codes will instead include medium and high risk areas in parentheses after the city name. These notes are only used as travel tips and have nothing to do with health status. For specific control policies, please follow the local joint prevention and control mechanism.

While the green itinerary code with an asterisk will not affect travel in general, we are encouraged to minimise unnecessary travel and unnecessary travel to medium- and high-risk areas. 2.What is the definition of "stop" on the itinerary card?

"Passing through" means that if you stay in a place for more than 4 hours and open the itinerary code with your mobile phone, the system will automatically record it as a pass or visit. Can I travel with an itinerary cassette "*"? A:

For those with an asterisk on the itinerary card, it is necessary to confirm whether you have ever been in a medium- or high-risk area. For people in high-risk areas, 14 days of centralized observation and 7 days of health monitoring will be implemented. During the period of centralized observation, the management regulations of the centralized observation point should be strictly observed, and nucleic acid testing and health monitoring should be cooperated to avoid cross-infection.

For people in medium-risk areas, 14 days of home observation and 7 days of health monitoring will be implemented; Where there are no conditions for home observation, centralized observation is to be implemented. During the home observation period, the relevant requirements of home observation should be strictly observed, and family protection should be done well, so that they do not leave home. Will the itinerary cassette "*" be quarantined?

3.The itinerary card with an asterisk does not necessarily mean that it will be quarantined, depending on the specific situation, if the user has been to a medium- or high-risk area, it will be quarantined, and if the user has not been to a medium- or high-risk area, it will not need to be quarantined. For example, in terms of administrative division, area A belongs to city B, and big data capture shows that area A is a medium-risk or high-risk area.

At present, except for Area A, the rest of City B are low-risk areas. The itinerary code is marked with an asterisk after City B, and further states that "the existence of medium-risk or high-risk areas in City B does not mean that the user has actually visited these medium- and high-risk areas". 4.

If you need to go out, you need to explain the situation to the relevant departments such as the prevention and control office of the destination in advance, understand the local epidemic prevention and control requirements, and cooperate with the relevant local work arrangements.

Epidemic is a Chinese word that refers to the occurrence and development of epidemics. [1]

Large-scale outbreaks include severe acute respiratory syndrome (SARS), influenza A (H1N1), and coronavirus disease 2019 (COVID-19).

"Plague" is a common term for epidemic acute infectious diseases, such as "plague" and "plague"; "Epidemic" refers to the occurrence and development of epidemics. The most severe epidemic in the world now is the "new crown pneumonia", which is a class B infectious disease.
