What is the mystery of the new cases in Tianjin?

On June 19, a 22-year-old COVID-19 patient was being treated in Tianjin Haihe Hospital. As the only COVID-19 patient in this hospital, his appearance broke the record that there were no new cases of COVID-19 infection in Tianjin 1 10. On June 19, Zhang Ying, deputy director of Tianjin CDC, told Wang Zhongqing reporter of Zhongqing Daily: "We haven't found the source of infection."

The patient is a chef in the western restaurant of Conrad Hotel in Tianjin, belonging to mild patients. According to Zhang Ying, Tianjin has cleaned up all close contacts, suspected exposed persons and their working and living environment as quickly as possible. At present, the results of nucleic acid detection and serum antibody detection of all samples are negative. From the results of epidemiological investigation, "it is not certain that he is related to the newly developed area of Beijing where the epidemic has recently occurred".

Extended data:

Zhang Ying responded that "the patient went to the fever clinic but was not isolated":

Zhang Ying said the patient's symptoms were atypical. First of all, he has no epidemiological history. He never left Tianjin/0/4 days before onset, and had no contact history with other cases. According to the case definition of the current COVID-19 diagnosis and treatment plan, he does not belong to the monitoring population. Secondly, his clinical symptoms are mild, only mild fever and dry throat, and there is no chest imaging change. "So the doctor can only preliminarily judge that he is other diseases before he gets the nucleic acid test results."

"This kind of confirmed patient with no epidemiological history is very rare in the country." Zhang Ying said that this also reminds everyone to upgrade the management methods of fever clinics. "All cases coming to the fever clinic should be managed according to suspicious cases, and patients must wait until the nucleic acid test results come out before leaving."
