A few hours after the local outbreak occurred, the epidemic information was released

A positive report of the primary screening shall be made within 2 hours after the positive person is found; After being diagnosed as a confirmed case or asymptomatic infection, a direct online report should be made within 2 hours. Cluster outbreaks are reported online through the Public Health Emergency Reporting Management Information System within 2 hours.

Persons who have tested positive for nucleic acid tests will arrive at the scene within 2 hours after being rechecked and confirmed, complete the investigation of the core information of the case within 4 hours, complete the preliminary epidemiological investigation report within 24 hours, and dynamically update the flow investigation report according to the progress of the epidemic.

The coronavirus pandemic began around September 12, 2019.

From December 19, 2019. At that time, many people in Wuhan had viral pneumonia, and the cause could not be found, and it was not until January 8, 2020 that it was finally determined to be a new coronavirus.

This has never been found in the human body before, and there is no drug to achieve the best effect, the main way of transmission is through coughing droplets or sneezing droplets, if you have direct close contact with the patient, you will also be infected. Symptoms: Some only have a fever or a mild cough, some will develop into pneumonia, and some will be more severe or even dead.

However, there is evidence that Wuhan was not the first region on the planet to show the coronavirus.

In March 2019, a research team at the University of Barcelona, Spain, detected the novel coronavirus in wastewater samples collected. In September, research showed that the coronavirus may have spread in Italy; On November 27, genetic material of the coronavirus was detected in wastewater samples from a municipality in Brazil. There are all kinds of signs that the new coronavirus is likely to have appeared in the world very early, but people did not pay attention to it at the time. One thing is really anomalous.

In July 2019, the U.S. military's largest biochemical research and development center, the Fort Detrick Biological Base, was investigated and closed by the U.S. Centers for Disease Control and Prevention. Not long after the closure of the Fort Detrick base, there was an inexplicable outbreak of "e-cigarette disease" in the nearby area.

There are some controversies:

Further research is needed. Some experts said that the new crown epidemic first occurred in the United States in September 2019, but at that time they thought it was an ordinary epidemic virus infection, and did not pay too much attention to it, which led to the spread of the virus in large quantities.

Some experts believe that the coronavirus pandemic began in Wuhan, China, in December 2019. These are yet to be confirmed by further research by experts.

But the most important thing about the epidemic is the prevention and control work now, and epidemic prevention and control requires everyone to work together to reduce the spread and protect others in order to protect themselves.

It started at the end of 2019, and it's been three years now.

Daily epidemic data is updated and released at 8 a.m. and 3 p.m. daily.

For humans, the new coronavirus is a "familiar and strange" existence. It belongs to the same family of coronaviruses as the severe acute respiratory syndrome (SARS) coronavirus and the Middle East respiratory syndrome (MERS) coronavirus, and is the third coronavirus to cause large-scale human infection in the past 18 years.

The new coronavirus is transmitted in the following ways:

1. Respiratory droplet transmission: It mainly refers to the transmission of the virus through the sneezing, coughing and exhaling gas of the infected person, and the droplets produced by talking.

2. Close contact transmission: It mainly refers to the droplets produced by the patient will be deposited on the surface of the object, after hand contact, if the contaminated hands are not cleaned in time, if the contaminated hands touch the nasal cavity, oral cavity and other tissues, it will eventually lead to infection.

3. Aerosol transmission: It mainly refers to the fact that the droplets will lose their moisture in the process of air suspension, but the remaining proteins and pathogens will form droplet nuclei, which will float to distant places in the form of aerosols and form long-distance transmission.

The daily epidemic data is 8 a.m. and 3 p.m. every day. The National Health Commission will hold a press conference at 3 p.m. on January 29 to introduce the relevant public guidance and recommendations on the prevention of the pneumonia epidemic caused by the new coronavirus. It is understood that from the 29th, the press conference of the National Health Commission will be held at 3 p.m., and the epidemic data will be updated and released at 8 a.m. and 3 p.m. every day.

The impact of the pandemicAlthough there may be a slight increase in domestic arrivals in the near future, the short-term iron ore ** is still limited in the current situation of low domestic mine production and a general decline in ports, steel mills and domestic mine inventories. However, affected by the epidemic and the obstruction of raw material transportation, the recent increase in production reduction and maintenance of steel mills has also increased, and it is difficult for steel mills to increase their demand for iron ore in the short term, or they will maintain the rhythm of on-demand procurement. Under the overall weak supply and demand pattern, it is expected that mining prices may remain high**.

**On the end, steel production continued to increase this week, and the output of both long and short processes increased. However, with the control of the epidemic in many places, the impact of logistics and transportation on steel production has increased recently, and the number of long and short processes and rolling product enterprises has increased, and it is expected that the steel industry will decrease in the later period.

The pandemic started on December 19, 2019.

The outbreak of the new crown epidemic during the Spring Festival travel period, a large number of people moved to accelerate the spread of the epidemic, and the liquidity risk continued to rise. However, with the continuous enhancement of comprehensive national strength in recent years, China's response capacity and medical level for major emergencies have been significantly improved, providing a good guarantee for the containment of the epidemic.

The reason for the outbreak.

One plausible explanation is that the coronavirus originated at the Huanan Seafood Market in Wuhan, and that the virus was transmitted from wild animals to humans. This explanation is very reasonable and accepted by many people, because SARS is like that. The SARS virus in 2003 was found in civet cats, which proved that people were infected by eating civets.

During the epidemic, maintain good personal and environmental hygiene, wash hands frequently, wear masks, implement the chopsticks system, cover your mouth and nose with tissues when sneezing or coughing, and keep your home and workplace well ventilated. Ensure adequate rest and sleep, avoid excessive fatigue, have balanced nutrition, and exercise moderately. Minimize unnecessary outings, do not gather, and maintain social distancing.
