Where is the source of the virus?
on December 7, Chengdu Pidu District, a new case of confirmed cases of new crown pneumonia. Immediately after the evening of the 7th, Lu’s husband, Zhao, detected positive nucleic acid in the isolation test and was diagnosed as a confirmed case. Among the 6 confirmed cases and 1 asymptomatic infected person, except for the first case of Lu, all other cases were detected positive for nucleic acid in screening of close contacts. All of these cases have been transferred to the Chengdu Public Health Clinical Medical Center for isolation treatment.
Where exactly is the source of the virus? Xie Qiang, director of the Chengdu Municipal Health and Wellness Commission, introduced the initial epidemiological investigation, the initial diagnosis of two cases of daily activities mainly near home, 14 days to Taiping Village vegetable market, the streets of two small clinics, their close contacts are mainly family members, tenants, clinicians, close contacts include local hospitals, schools, farmers’ markets and other places of activity.
Epidemiologist, Sichuan Provincial Health and Health Commission to respond to the new crown pneumonia outbreak leading group of disease prevention and control expert group leader Zhu Xiaoping said, according to the current epidemiological investigation, the patient Lu Moumou’s trajectory is relatively limited, mainly in the vicinity of her home; Zhao Moumou is pulling a tricycle, a relatively large range of activities, the trajectory is more complex, and is now being investigated and verified. “The seven samples with positive primary screening are mainly door handles, switches, chopping boards, food in the refrigerator, etc. in the patient’s home, which indicates that the virus is very serious contamination of the patient’s home.” Zhu Xiaoping said.
Zhu Xiaoping introduced the patient’s trajectory, the onset of the investigation has been carried out, while in the grasp of the strain of genetic sequencing, comparison, from the sequencing results to explore the source of this strain.
“The first confirmed case of the patient Lu has been to the vegetable market traffic, in a short period of time to trace the source of great difficulty.” Luan Rongsheng, deputy head of the Epidemic Prevention and Control Group of the Leading Group for Response to Novel Coronavirus Pneumonia Outbreak of the Sichuan Provincial Health and Wellness Commission and professor at the West China School of Public Health of Sichuan University, said.
“Currently, tracing the source of the virus still needs more flow investigation support. It is imperative to grasp the critical period of prevention and control and strictly control the spread of the epidemic.” Luan Rongsheng believes that the general public does not need to panic, if they just rub shoulders with cases on the road, the possibility of contracting the virus is unlikely.
When will the screening be completed?
After the outbreak of the epidemic, Chengdu quickly entered a state of war, in accordance with the principle of “should test as much as possible, willing to test as much as possible”, the urgent nucleic acid testing of key areas to investigate. By 20:00 on the 8th, Chengdu had expanded nucleic acid testing to cover 255,200 people and completed testing for 60,500 people. At the same time, the investigation, has been traced to confirmed cases and asymptomatic infected close contacts 163 people, has completed sampling 143 people, negative 73 people, the rest of the results to be released.
It is understood that in order to ensure that “no one is left out”, Chengdu also plans to carry out a second round of nucleic acid testing of close contacts and other types of contacts.
Luan Rongsheng said, the first round of accurate screening of relevant close contacts, the second round of relevant contacts around the screening, two rounds of “envelope” is likely to be able to spread the virus range “envelope”.
“Epidemiologically speaking, the last case was found, and all the close contacts of the case were found, and then after an incubation period of 14 days, if no new cases occur, then the transmission can basically be declared over.” Luan Rongsheng said that the current Chengdu in grabbing the 14 days of the critical period, a number of places overnight nucleic acid testing, and the virus race.
In the early morning of the 8th, PI area epidemic prevention and control command started PI cylinder street of six villages and communities flow transfer work. At present, PI tube street set up 175 nucleic acid detection points, Tangchang town set up 8 nucleic acid detection points, 1,100 disease control personnel, 5,000 party cadres volunteers on 24-hour shifts testing. Reporters in Taiping Village, the first confirmed case of Lu Moumou lived near the courtyard to see, the courtyard has been all cordoned off isolated, the disease control personnel disinfection regularly, the police are also on the side 24 hours to maintain order.
On the 9th, Chengdu Chenghua District Huadu Yunjingtai district is designated as a medium risk area. The reporter learned that all residents in Huadu Yunjingtai subdistrict have completed nucleic acid testing.
Sichuan Agricultural University Logistics Management Office Party Secretary Pan Hong told reporters that the school has been to the epidemic prevention and control of key areas of students and teachers to check, according to the mapping situation, the first batch of students and teachers have been free nucleic acid testing.
The reporter learned that, at present, Chengdu has 141 nucleic acid testing institutions, the maximum daily testing capacity can be achieved single tube single person times 290,000 copies. The city also has 35 designated hospitals in reserve, which can start more than 6,000 rescue and treatment beds in the first instance, with a reserve of more than 17,000 extended beds.

How to interrupt the transmission chain of the virus?
At present, the city of Chengdu has been Pixou District, Pixou Street Taiping Village, Chenghua District, Cuijiadian Huadu Yunjingtai District, Pixou District, Tangchang Town, Yongan Village, Group 8 upgraded to the risk area, the implementation of comprehensive site control and disinfection. At the same time, also the people’s hospital in PI district, Taiping Village 11 groups, Shaxi wholesale farmers market, PI district Minyang school, the central park district, the relevant bars, restaurants and other areas to implement on-site control and disinfection. Chengdu entertainment industry association also issued an emergency notice, requiring the number of people consumed in Chengdu entertainment venues do not exceed 75%.
In the afternoon of the 8th, the reporter went into Taiping Village, the front line of the epidemic prevention and control, and saw that most of the villagers were closed and consciously isolated at home. The entrance and exit of the village were cordoned off, and access was temporarily prohibited. The village also organized nearly 100 volunteers to participate in the prevention and control of the epidemic.
On the 9th, the reporter saw at the scene of Huadu Yunjingtai district, the district has been closed, the periphery pulled up a cordon, outside the district there is a courier placement point, community volunteers here to watch and deliver living supplies for more than 300 residents. “Through the cell door outside the fixed point sorting, fixed person trolley to the unit door, and then sent upstairs to the door of households to provide residents with living materials.” Chenghua District Jumping Stomp River Street Jumping Stomp River Community Party Committee Secretary Wang Shi Ru said.
Sichuan Agricultural University uses face recognition gates, infrared thermometers and other technical equipment to strengthen the campus gate and dormitory building door prevention and control. At the same time, teachers and students are required in principle not to leave the school premises to go out.
Luan Rongsheng introduced, so far the confirmed cases are Lu’s close contacts, as long as the timely interruption of the transmission chain, Chengdu epidemic should not spread widely.
In this outbreak, the 8th Lu’s granddaughter Zhao Moumou was diagnosed sparking widespread concern. Through epidemiological investigation, Zhao’s main places of stay in the past 14 days include the Central Park of Zhongyue, Hi Blues nail salon, Sea Mist Lane small bar and other crowded places.
Chenghua District Mayor Pu Fayou introduced, as of December 8, 6 p.m., according to Zhao’s activity trajectory, has tracked Zhao’s close contacts 91, 130 sub-close contacts, general contacts 838, all implemented isolation control measures and nucleic acid testing.
The epidemic, Zhao’s ID card and other personal information was leaked, interfering with the normal development of epidemic prevention and control. “In the face of the illegal dissemination of information, personal attacks, malicious slander, defamation and other bad behavior, information subjects should decisively protect their rights according to the law.” Wu Yingyan, a lawyer at Guangdong Legal Shengbang Law Firm, believes that in the process of epidemic prevention and control, information users should handle personal information for clear and reasonable purposes and take necessary measures to safeguard the safety of the information subject.
