The Ordos CDC pointed out that the questionnaire survey showed that the positive has been turned negative as well as is in the infected period of the residents of 12,820 people, accounting for 46.61% of the total number of people in the survey; there have been symptoms but did not do the antigen of the residents of 3,742 people, accounting for 13.61% of the total number of people in the survey.
Among the 16,562 people who confirmed that they were infected with the new coronavirus, 78.89% showed symptoms of fever, 68.93% showed symptoms of headache, 64.88% showed symptoms of cough and phlegm, 61.98% showed symptoms of muscle ache, 61.23% showed symptoms of sore throat, 57.52% showed symptoms of fatigue, 53.74% showed symptoms of fear of cold and chills, 51.84% had a stuffy and runny nose, 41.18% had joint pain, 36.05% had a loss of appetite, 25.23% had a reduced or lost sense of taste or smell, 12.88% had abdominal pain and diarrhea, 10.6% vomited, 10% had mild overall symptoms, 8.64% had symptoms of dyspnea, 3.53% had a rash or itchy skin symptoms, and only 1.75 percent had no symptoms.
The Ordos CDC said that as of Dec. 30, the infection rate of the new coronavirus among residents who participated in this survey was 60.22 percent, suggesting that the new coronavirus infection in Ordos is in a high prevalence stage.

Why feel around the "asymptomatic infected people proportion is very small"? Experts say why
There has been widespread concern about the proportion of asymptomatic people infected with the new strain of the virus. Earlier this month, Guangzhou City, an epidemic prevention and control press conference released data show that the current round of the epidemic in Guangzhou City, asymptomatic infected people accounted for about 90% of the total number of infected people. Recently, a number of experts and scholars have also expressed the view that with the weakening of the pathogenicity of Omicron and the popularization of vaccination, the proportion of asymptomatic infected people is relatively high. And as more and more people become infected and share their experiences of battling the new coronavirus with friends and family, many people are finding that they seem to be "surrounded by lightly infected people and the number of asymptomatic infected people is very small".
Wu Hao, head of the National Health Commission's expert group on community prevention and control of the new coronavirus outbreak and dean of the School of Family Medicine and Continuing Education at Capital Medical University, said in an interview with the Global Times on Dec. 12 that the reason for this feeling is because of the change in detection strategies and preventive and control measures, which were basically nucleic acid tests before, which are more sensitive than antigenic tests, and that many people in home quarantine have started to use antigenic tests. Home isolation of the public began to use antigen detection, many asymptomatic infected through antigen detection kit can not be detected, which results in symptomatic infected people accounted for more of the "illusion".
Previously announced new crown pneumonia diagnosis and treatment program clearly pointed out that the new crown asymptomatic infection for the nucleic acid test is positive, but there is no relevant clinical manifestations, such as fever, dry cough, malaise, sore throat, smell loss, diarrhea and other self-perceived or clinically recognizable signs and symptoms, and CT imaging does not have the new crown pneumonia imaging features. Mild cases, on the other hand, are defined as those with a positive nucleic acid test and a more mild clinical presentation, usually characterized by fever, respiratory tract infection, mild malaise, and usually no dyspnea or chest tightness, and no pneumonia on imaging.
"But now many people may feel that many of the detected infected people around us have fever, cough, sore throat and other symptoms, which seems to be inconsistent with our previous publicity there is a large number of asymptomatic infected people, in fact, the two are not contradictory," Wu Hao pointed out, before we use the "Nucleic acid test positive" as the gold standard for the diagnosis of the new crown, according to the ninth edition of the national diagnosis and treatment program of the new crown, once the CT value of the nucleic acid reagent is less than 40 will be judged as nucleic acid test is positive, greater than 40 will be negative. Nowadays, we adopt the antigen detection method as an auxiliary detection means, and practical observation shows that generally speaking, the CT value of the nucleic acid test of the infected person should be less than 28, and only when the antigen test is carried out will the "C" and "T" of the reagent box show red or purple bands. It is only at this point that the antigen test is likely to screen positive for infection. The difference between the two tests has resulted in many asymptomatic infected people who test positive for nucleic acid being a "healthy population" by antigen testing. "In fact, many asymptomatic infected people with low viral loads cannot be detected by antigen testing. The reality also found that even if the antigen test negative people positive nucleic acid test, the viral load is also low, the infectivity is also weak."
In the ninth edition of the prevention and control program of the new crown pneumonia, for the first time, it is clear that primary health care institutions can increase antigen testing of suspected patients, and with the gradual optimization of the prevention and control program of the new crown, the scope and frequency of nucleic acid testing is gradually narrowing, and encourages people with the need for independent antigen testing can be carried out at any time, in accordance with the principle of autonomy and voluntariness of the self-antigen testing. As a result, many people in home isolation have begun to use antigen testing to determine whether they and their family members are infected with the new crown.
"If we adopt antigen testing, one, because we feel we are at risk of being infected, and two, because we realize that we are experiencing symptoms and therefore we start testing, in this case it would be the symptomatic infected people who would seem to be the ones who are more infected because many of the asymptomatic infected people don't seek out screening." Wu Hao stated.
Wu Hao noted that we now need to be more rational about the adjustments to the epidemic's prevention and control measures. After nearly three years of scientific resistance to the epidemic, many people have developed good hygiene habits such as keeping a proper social distance, wearing masks and washing hands frequently, all of which can greatly help us avoid the spread of the virus in the future.
For the adjustment and gradual optimization of anti-epidemic policies, Wu Hao said, this is by no means simply "liberalization", not to mention "lying flat", but in consideration of the economic production activities and the people's normal life after the integration and balance. "The formulation of public **** health policy must be a strategy introduced after all-round consideration. Omicron has been presented as a strong transmission, but the pathogenicity of the relatively low characteristics, if we then use the traditional way of epidemic prevention to deal with, then the price to pay will be difficult to bear. In the future, we have to continuously optimize and adjust our epidemic prevention policy for the characteristics of the new coronavirus, taking small steps without looking back. Now we need to seize the time to do a good job of preparation, including the rapid promotion of vaccination of the elderly, strengthen the medical supplies reserve, strengthen the grass-roots medical personnel diagnosis and treatment capacity training, focusing on the prevention and treatment of the new crown of the vast majority of rural areas, as well as children's prevention and treatment, optimize the measures for the characteristics of the virus mutation, to increase the popularization of science to respond to the public's concerns and doubts in a timely manner, to eliminate the panic, to prevent the run on the medical treatment, and to put limited medical resources on 'knife edge'. Medical resources are used on the 'knife edge' to reduce the incidence of severe and fatal cases."
