After China's relaxation of epidemic control, crown diseases in multiple regions and cities have increased significantly.However, Baidu Index, which reflects the search of the keywords of netizens, shows that Beijing netizens' "fever" keyword indexes have risen rapidly since early December, and after reaching the peak on December 12, they turned their heads sharply.Recently, the main symptoms of the main symptoms of crown diseases such as "cough" and "dry throat" have also become stable and declined.

The Baidu index is based on the search volume of netizens on Baidu as the data basis, and the result of weighted calculation.

According to Caixin.com, after the optimization of China's epidemic prevention policy, due to the knowledge of symptoms or reserves in response to infection, Beijing people's search popularity of keywords related to crown diseases has increased.For example, the "fever" keyword index entered the upward on December, and the growth rate was faster after December 7.Accompanied by it, in early December, there were situations such as hot nostalgia and tight supply of antipyretic drugs appearing in Beijing.

According to reports, a large number of people have self -testing antigen and home treatment after the symptoms of coronary infections. The Baidu search index of related keywords has certain reference value.One of the observations.Compared with Beijing, Baoding's "fever" Baidu Index was earlier. After the peak reached the peak on December 10, it has now dropped to 40 % of the peak.In addition, the "fever" index also declined after the "fever" index continued to rise, reaching the peak of the stage on December 16; the "fever" index in Shanghai also fell short -term on December 18.

In addition to the overall situation of local crown disease, the progress of the disease after the infection of the people may also affect the search behavior.The "fever" index of Baoding and Beijing is earlier than "cough". The peaks of "fever" such as Guangzhou and Shanghai appear late cities. The "cough" search situation has not yet seen down.

According to the information released by the Beijing Municipal Health and Health Committee on December 8, after general young and middle -aged patients were infected with crown disease, the course of disease was about seven days.On the first day, it may feel slightly sore, dry and sore, and fatigue; the second and three days of fever and throats intensify; on the fourth day of the body temperature, the peak of the body temperature decreases, and some people start running nose and coughing; the body temperature is basically normal on the fifth day.Flowing nose, soreness, cough, and fatigue still exist; no fever on the sixth day.Symptoms such as cough and runny nose are aggravated; all symptoms on the seventh day have begun to improve significantly.

However, the search index reached its peak in the short term, which does not necessarily mean that the search peak is over.For example, according to Baidu's forecast as of December 18, the peak of the Beijing epidemic search index will end on January 13, 2023.

On the other hand, the search index is not a real infectious data statistics, nor is it a professional medical prediction. It cannot be directly regarded as the trend of the epidemic itself. The prediction of the search index's peak does not represent the prediction of the peak of the epidemic.For example, the search index and information acquisition demand are associated. In the early days of the development of epidemic conditions, the public's demand for epidemic prevention information was strong and centralized. With the promotion of various channels, the people's cognition was strengthened, the search index and the progress of the epidemic situation progressed.The correlation may also change.
