Xiamen built a shelter overnight.

Xiamen built a shelter overnight, and the nucleic acid test for all staff in Xiamen, Fujian Province began on June 5438+04. The shelter nucleic acid laboratory was built overnight in Xiamen International Convention and Exhibition Center on June 5438+04, 2004. This series of "Falcon" gas film laboratories have supported the front lines of epidemic prevention in Guangzhou, Nanjing and Yangzhou.

Xiamen built a shelter overnight 1 to fight the epidemic "black technology"!

In order to further improve the local nucleic acid detection ability in Xiamen and help all the staff in Xiamen meet the needs of nucleic acid detection, six groups of Falcon gas membrane laboratories were built in Xiamen International Convention and Exhibition Center yesterday and put into use as planned today. The mobile shelter laboratory outside the convention and exhibition center was partially put into use yesterday, and mixed sampling was carried out according to 1: 10. Each mobile shelter laboratory can detect10-150,000 nucleic acid samples every day.

Falcon gas film laboratory

According to reports, this is the first time that Falcon Film Laboratory has been put into use in our city. It is the largest mobile laboratory in China at present, consisting of five groups of "three-cabin integrated" gas film laboratories and 1 group of "five-cabin integrated" hard gas film laboratories.

Each group of gas film cabin is a reagent preparation area, a sample processing area and an amplification area. Equipped with automatic detection equipment such as automatic opening and prototyping, automatic nucleic acid extraction, automatic sampling and PCR amplification instrument.

The laboratory will rely on inspectors and automation equipment to realize 24-hour uninterrupted operation.

Previously, this series of "Falcon" gas film laboratories had supported the epidemic prevention front lines in Guangzhou, Nanjing, Yangzhou and other places, helped the local areas greatly improve their nucleic acid detection capabilities in a short period of time, and even helped Guangdong Province set two national highest epidemic prevention records.

The laboratory was jointly established by Guangzhou Laboratory and National Respiratory Center, with Zhong Nanshan, an academician of China Academy of Engineering as the director, and operated by Jinyu Medical.

Xiamen built a shelter overnight. There are 50 new local diagnoses in China.

From 0: 00 to 24: 00 on September 14, 3 1 provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps reported 73 newly confirmed cases in COVID-19. Among them, there were 50 local cases (all in Fujian, including 33 cases in Putian, 5 cases in Xiamen 12 and Quanzhou), among which 9 cases were converted from asymptomatic infected persons to confirmed cases (all in Fujian). Asymptomatic infection 16 cases were added, including 15 cases imported from overseas and 1 case imported from local (Xiamen, Fujian).

A shelter nucleic acid laboratory was built overnight in Xiamen, Fujian.

On June 4th, 65438, Xiamen, Fujian Province, nucleic acid detection began in the whole city. The shelter nucleic acid laboratory was established overnight in Xiamen International Convention and Exhibition Center on June 4th, 65438. This shelter laboratory can operate 24 hours a day with inspectors and automation equipment.

Full-time nucleic acid testing started in Zhangzhou, Fujian.

According to big data analysis, there have been frequent exchanges between Zhangzhou and Putian, Xiamen and Quanzhou recently. At present, everyone in Longhai District, Changtai District, Taiwanese Investment Zone and Zhangzhou Development Zone of Zhangzhou City has started nucleic acid testing. By 24: 00 on September 14, 620,000 people had registered.

At the same time, students from Zhangzhou municipal kindergartens, Zhangzhou longwen district and xiangcheng district public private kindergartens will be suspended from September 15 until further notice. Students from Zhangzhou Primary School, Zhangzhou longwen district Primary School and xiangcheng district Public Private Primary School will be suspended from September 15 to September 2 1 day and start online teaching.

Clean up the middle and high risk areas in Yunnan

From 8: 00 on September 15, the villagers' group of Dadonghe in Jiedong Village Committee, Mengmao Town, Ruili City, Yunnan Province was adjusted from a medium-risk area to a low-risk area, and the medium-high risk area in Yunnan Province was cleared up.

Complete propagation chain of δ mutant

COVID-19 is still prevalent all over the world, and COVID-19 Delta mutant has quickly become an epidemic strain.

The team of Professor Tang Xiaoping and Professor Feng Li from the Eighth Affiliated Hospital of Guangzhou Medical University, and the team of Academician Zhong Nanshan and Professor Chen Ruchong from Guangzhou Institute of Respiratory Health, the First Affiliated Hospital of Guangzhou Medical University, aimed at the "5.2 1 COVID-19 epidemic" caused by Delta mutant, combined with epidemiology and viral genome sequencing technology, combined with clinical resources, accurately described the complete transmission chain of Delta mutant for the first time in the world, and described the clinical characteristics and viral dynamics characteristics of the case in multiple directions. Recently, the research results were published in Electronic Journal of Clinical Medicine, a subsidiary of the international authoritative journal The Lancet.

According to the previous epidemiological investigation and viral nucleic acid gene sequencing, the "5.2 1 COVID-19 epidemic" was caused by a Delta mutant with a clear transmission chain. This study is the first time to trace and completely report the clear transmission chain of this epidemic. The outbreak began with a 75-year-old woman who was accidentally exposed to infection and infected three other people through close family contact or dinner.

The researchers observed that the virus was mainly transmitted through direct and indirect close contact, among which 30.8% of infected people were transmitted through meals, followed by family contact (30. 13%), community transmission (18.59%) and other transmission routes including work and social contact (19.87%).

At the same time, the researchers included patients with "5.2 1" epidemic into the queue of patients infected with wild strains in novel coronavirus, COVID-19 in 2020, analyzed the clinical characteristics and virus dynamics of "5.2 1" epidemic cases from many aspects, summarized the characteristics of Delta mutant strains, and searched for risk factors for severe cases.

The researchers found that the Delta mutant has a short incubation period and a fast transmission speed, and the median incubation period is only 4.7 days, which is significantly shorter than that in wild strains (6.3 days). Further subgroup analysis showed that in the non-severe group, the virus incubation period of Delta mutant patients (4.0 days) was significantly shorter than that of wild strains (6.0 days). Delta mutant can spread for 4 generations in 10 days, and the fastest intergenerational transmission is less than 24 hours.

Compared with wild strains, the viral load of patients infected with δ mutation increased significantly (the median CT value of the former was 34.0, and that of the latter was 20.6, and the lower the CT value, the higher the viral load), and the time for the nucleic acid of patients infected with δ mutation to turn negative was also significantly longer than that of patients infected with wild strains.

The researchers also found that infection with Delta mutant is a risk factor for predicting the transformation of disease into critical disease. In COVID-19 patients aged 60 years and above, the risk of critical illness in Delta mutant group is 65438 0.45 times higher than that in wild strains group. In addition, the infection rate of Delta mutant was 2.98 times higher than that of wild strain.

Researchers believe that this study reveals that Delta mutants have the characteristics of short incubation period, fast transmission speed, high viral load and long time for nucleic acid to turn negative, and are more likely to develop into critical diseases. Therefore, it is very important to track, isolate and find virus-infected people in time, implement timely control in key places and implement nucleic acid screening in local areas under special circumstances. The practice of finding the source of infection quickly and cutting off the route of transmission provides "Guangzhou experience" for COVID-19 to prevent and control Delta mutation.
