Feng Zijian, a researcher at the Chinese Center for Disease Control and Prevention, said that since the outbreak of the Guangzhou epidemic on May 21, the number of cases has exceeded one hundred, and there is a phenomenon of transmission in homes and public places
.

Through epidemiological investigations, the transmission relationship between cases is relatively clear, and most recently reported cases come from closed control areas and isolated observers

"It has been more than 14 days since the epidemic was discovered, and no related cases have been found in other provinces.
Only a limited amount of long-distance transmission has occurred in Guangdong Province, and the transmission relationship is clear, and prevention and control are relatively timely
.

" Feng Zijian said

At present, Guangdong Province has implemented a strict nucleic acid test negative certification system for personnel transported out of the province by air, railway, road, and water, and shortened the time for people from Guangzhou, Foshan and other places to leave Guangdong with a nucleic acid negative certification system to 48 hours to guide the province’s personnel.
It is necessary not to leave Guangdong
.

Feng Zijian said that due to the characteristics of the epidemic itself, such as the number of middle-aged and elderly cases, the number of clusters of cases, gatherings, and gatherings, the lower vaccination rate before the onset of infection, etc.
, the high viral load, strong transmission, and more These factors have put forward new and higher requirements for the implementation of epidemic response and prevention and control
.

"Combined with the current prevention and control measures taken in various places, experts have analyzed and analyzed that with effective measures to deal with clusters of epidemics in place, this Guangzhou epidemic shows a trend of declining positive infections, and the scope of risk is becoming increasingly limited, but it is not ruled out.
There may be scattered cases
.

" Feng Zijian said

Feng Zijian said that Guangzhou has recently implemented strict prevention and control strategies and measures, and the situation has tended to ease and is developing in a positive direction
.

Focus 2: What are the characteristics of clinical treatment? There are many middle-aged and elderly patients, and the disease progresses quickly.
Adopt the treatment strategy of "one patient, one file, one policy"

Guan Xiangdong, an expert in the Medical Treatment Team of the Guangdong Working Group of the Joint Prevention and Control Mechanism of the State Council and director of the Department of Critical Care Medicine of the First Affiliated Hospital of Sun Yat-sen University, believes that compared with more than 20 local cluster epidemics that have occurred in China in the past, the epidemic in Guangzhou is There are four characteristics in clinical manifestations
.

State Council

The first is that the incubation period of the virus is relatively short, most of which begin within one week of infection
.

The second is that the proportion of patients who become severe and critical after the onset of illness is higher than before, reaching 10%-12%.

"The local epidemic showed significant familial aggregation, and features a family clusters of disease, that is, the elderly and children infected and more
.

" Pipe eastward said that this time the epidemic, severe disease People's Congress are mostly 70-90 years old The elderly also made it more difficult to treat

At present, the Eighth Hospital Affiliated to Guangzhou Medical University, which treats patients with new coronary pneumonia, adopts a treatment strategy of "one patient, one file, one policy" for patients with new coronary pneumonia, and accurately treats them according to the actual conditions of the underlying disease and personal physique, and starts medical treatment from the early stage of the disease Intervene to prevent severe disease
.

City, eight hospital president Leichun Liang introduced, City, eight hospitals and a support specialist in real-time to discuss the patient's condition and judged, adjust the treatment according to the patient's condition; while focusing on humane care, such as regular chat with patients, encouraging them to eat sleep, Keep a positive attitude and so on
.

Under the treatment of integrated traditional Chinese and Western medicine, the nutritional support of patients is guaranteed, personalized diet services are provided, and medicated diet therapy programs are formulated to improve immunity

Dean

Cai Weiping, chief expert of the Infectious Disease Center of the Eighth Hospital of the City, said that there are no specific antiviral drugs, and supportive treatment is the mainstay for these patients
.

For asymptomatic infections, traditional Chinese medicine treatment is mainly given

Focus 3: How far has the traceability progressed? The source of the epidemic is still being traced, and strict control is required during the Dragon Boat Festival

Feng Zijian said that the current analysis of viral gene sequencing results for infected persons showed that the gene sequence results are highly homologous.
They are all the fastest-spreading Delta mutant strains (B.
1.
617) that were first discovered in India and have epidemiology.
According to investigation and experimental evidence, it can be considered that this round of the epidemic in Guangzhou was caused by overseas imports
.

"This epidemic is also the first time that a mutant strain of the new coronavirus discovered in India has a local epidemic in China
.

At present, traceability is still in progress

Lin Peng, chief scientist of the Guangdong Provincial Center for Disease Control and Prevention, introduced that since the outbreak of the epidemic on May 21, Guangdong Province has gradually expanded the scope of nucleic acid testing based on actual conditions.
Guangzhou and Foshan have implemented full-staff testing, and Shenzhen has launched routine testing for quarantined personnel and key populations.
Investigation and testing: On June 7, Guangdong Province, based on the situation of epidemic prevention and control, initiated hierarchical nucleic acid testing in 10 prefecture-level cities, including Zhuhai and Zhongshan, and quickly promoted large-scale population screening in the Pearl River Delta and key areas in the east, west and north of Guangdong
