(Fighting against new crown pneumonia) Guangzhou isolated hotel staff infection is highly homologous with imported cases abroad

  China News Service, Guangzhou, September 5 (Wang Hua, Liu Jinjin) The Guangzhou Municipal Health Commission announced on the 5th that a staff member of an isolated hotel in the city tested positive for the new coronavirus nucleic acid. The gene sequencing results showed that the person and the isolated hotel 9 The genetic sequencing of confirmed imported cases reported on April 4 is highly homologous.

Since August, the quarantine hotel has reported a total of 7 cases of imported infections from abroad.

  According to reports, during the routine nucleic acid test on the staff of the quarantined hotel on the 4th, it was found that a staff member had a positive result of the new coronavirus nucleic acid test. The staff has been closed-loop transferred to the Eighth Hospital Affiliated to Guangzhou Medical University for observation. The current situation is stable. .

  The person Xu was engaged in food delivery and room cleaning, and he lived in an isolated hotel after August 30. The nearly five routine nucleic acid screening tests on September 4 were all negative.

The gene sequencing results showed that the person and the imported confirmed case Yang reported by the isolation hotel on September 4 were highly homologous. They were both Delta mutant strains. Combined with epidemiological investigations, the person was arrested after September 1. The possibility of infection is great.

  Chen Bin, deputy director of the Guangzhou Municipal Health Commission, said that after expert research and judgment, Xu is associated with imported confirmed cases overseas, and the risk of community transmission is small.

  Zhang Zhoubin, deputy director of the Guangzhou Center for Disease Control and Prevention, said that the investigation found that Xu went to the door of the isolation room of the imported case Yang at 14:03 on August 30 and 14:13 on September 1 to collect garbage.

However, Yang's sampling result at 16:00 on August 30 was still negative. Combined with nucleic acid sequencing and flow control conditions, Xu should be accidentally exposed when he was collecting garbage on the afternoon of September 1 and causing infection.

  It is understood that Xu currently has 56 staff members in the quarantine hotel and 103 people living in quarantine. Since August, the quarantine hotel has reported a total of 7 cases of imported infections from abroad.

  Guangzhou City has immediately activated an emergency response mechanism for epidemic prevention and control, and comprehensive epidemic prevention measures such as epidemiological investigation, nucleic acid screening, personnel investigation, deployment and control of key sites and terminal disinfection of the environment.

As of 24:00 on September 4, 55 people (including 1 family member) were closely connected to the case, all of whom were staff in the same quarantine hotel, and all had implemented centralized quarantine health management. All nucleic acid samples had been sampled, and the first nucleic acid test results were negative.

112 people have been checked closely in Suici, and all have implemented centralized isolation and health management. The first nucleic acid test results were all negative.

  Guangzhou has also deployed medical and nursing forces to conduct nucleic acid investigations for all employees in Jianshe Street, Hongqiao Street, Dongshan Street, Huale Street, and Dengfeng Street in Yuexiu District.

As of 24:00 on September 4, 92,185 people had been sampled and the results were all negative.

  Zhang Zhoubin said, “This case incident once again reminds us that the infectious ability of the new crown virus, especially the delta mutant strain, is still very strong. The current overseas epidemic situation is still severe and the pressure of foreign defense import continues, and personal protection must not be relaxed. ".

  As of 24:00 on September 4, Guangzhou has received 33.627 million doses of new crown vaccine and 17.807 million people; 16.085 million people have completed the entire vaccination, with a coverage rate of 86.1%.
