There is some controversy about when the pandemic began, and 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.

Since December 2019, there has been a novel coronavirus pneumonia in Wuhan, Hubei Province, which is a new acute respiratory infectious disease that has been included in the Category B infectious diseases stipulated in the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases, but is managed as a Category A infectious disease.

The official report of the beginning of the novel coronavirus pneumonia was in December 2019, and a study published in the international medical journal The Lancet on January 24** showed that the first confirmed case of novel coronavirus pneumonia became ill on December 1, 2019.

Pathogenesis: 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.

It is worth noting that severe and critically ill patients may have moderate to low fever or even no obvious fever during the course of the disease. Mild patients only present with low-grade fever and slight fatigue, but no signs of pneumonia. Judging from the current number of cases, most of the patients have a good prognosis, and a few patients are in critical condition.

Older people and those with chronic underlying medical conditions have a worse prognosis. Cases in children have relatively mild symptoms.
