Beijing News (Reporter Li Yukun intern Xie Yanbing Fu Zhonghang) Since the cluster epidemic occurred in Beijing’s new site on June 11, Beijing has reported a total of 335 local confirmed cases, 205 hospitalized, and discharged after treatment as of July 14. 130 cases. 18 cases of asymptomatic infections still under observation.
It is worth mentioning that, as of 24:00 on July 14, Beijing had no new local confirmed cases for 9 consecutive days.
What are the symptoms of the above cases? What is the current cure? The following is a review by the Beijing News reporter based on daily public data from the Beijing Center for Disease Control (case data released as of July 13).
18 cases of nucleic acid test results "yin then yang"
The public information of 335 diagnosed patients showed that 18 patients had a nucleic acid test result of “yin then yang”.
For example, Case 2 was diagnosed on June 24, male, 29 years old. Reported a sore throat on June 13, and the symptoms disappeared after self-administration of the drug; on June 14, the cell nucleic acid screening was negative. Because many of the co-residents were diagnosed cases, they were quarantined and observed from June 16, and the nucleic acid test was conducted at the isolation point on June 22. The results were positive on June 23 and confirmed on June 24. The clinical classification was normal.
There is also a confirmed case 2 on July 2nd, female, 32 years old. Symptoms such as fever occurred on June 13, and her husband drove to Youanmen Hospital for treatment. The result of nucleic acid test was negative. On June 22, both the patient and his 2-year-old daughter were identified as close contacts of the confirmed case. They were transported by special vehicle to the centralized isolation point on the same day for centralized medical observation. During this period, the patient's nucleic acid test result was positive, and the diagnosis was confirmed on July 2nd. The clinical classification was ordinary.
The other two patients had a negative nucleic acid test result after two and four tests were negative.
According to the daily public statistics of the Beijing Center for Disease Control and Prevention, 8 patients have been tested for antibodies. Except for one patient who tested negative for both antibodies, the rest were positive.
It is understood that the serum antibody detection method has the advantages of convenient sample collection and simple and fast operation, and can be used as an effective supplement to nucleic acid detection. The detected antibodies are mainly divided into IgM and IgG, which are the abbreviations of immunoglobulin M and G, respectively. When the body is exposed to the virus, IgM antibodies are produced at the earliest time, with low concentration and short maintenance time, which is a diagnostic indicator of acute phase infection; IgG is produced late, high concentration, and long maintenance time. Positive serum IgG indicates mid-late infection or previous infection.
Clinically, light and common types have been cured and discharged in 130 cases
The confirmed cases are mainly light and common types, with a total of 329 cases, accounting for 98% of the total number of cases. The proportion of severe and critically ill patients in this outbreak is obviously low.
At the Beijing Epidemic Prevention and Control Press Conference on July 13, Wu Guoan, deputy director of Beijing Ditan Hospital, introduced that as of 15:00 on July 13, a total of 5 critical cases and 21 severe cases were diagnosed. 7.8% of all confirmed cases. In the treatment of 26 severe and critical cases, 25 cases have been converted to ordinary cases, including 1 case has been discharged. Among the confirmed cases in the hospital, there is still one case of critical illness.
As of 24:00 on July 13, 130 patients had been cured and discharged. Among them, 80 men and 50 women. The maximum age is 66 years old, the minimum age is 1 year and 7 months, the average age is 39 years old, the hospital stay is up to 30 days, the shortest is 11 days, and the average is 22 days. In addition, 16 patients with asymptomatic infections had their nucleic acids turned negative and were discharged.
Fever and throat discomfort are the first symptoms
The reporter analyzed the information on the first symptoms of 134 diagnosed patients and found that fever was the most common first symptom, and 60 people had fever. Fifty-six people have experienced throat discomfort, such as sore throat, itching, and dry discomfort, accompanied by cough. There are two types of dry cough and sputum. Some patients experienced generalized discomfort with specific symptoms, including fatigue, chills, sweating, and soreness.
In general, the first symptoms of recently diagnosed cases in Beijing are similar to colds, but some patients also have different symptoms such as abdominal discomfort, dry mouth, nausea, chest tightness or chest pain, and joint discomfort.
A man diagnosed on June 13 showed the most symptoms. The patient is 35 years old and is from Baoding, Hebei Province. The working unit is Beijing Xinfadi Market, self-employed, and currently lives in Xinfadi Operator Paradise. On the 8th, he developed fever, dry cough, runny nose, fatigue, dizziness and muscle aches. The highest temperature was 38℃. At the Tiantan Hospital on the 12th, the nucleic acid test was positive, and the diagnosis was confirmed by experts, and the clinical classification was light.
At a news conference on the prevention and control of the New Coronary Pneumonia epidemic in Beijing on June 30, Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, reminded that the pathogenic mechanism of the New Coronary Pneumonia virus is complex, and the disease characteristics need to be further studied. Symptoms are diverse, atypical, and not easy to attract attention. Daily personal protection should be done, attention should be paid to health conditions, and all symptoms should be protected in a timely manner.
