Original title: Shenzhen sea, land and air epidemic prevention upgrade! Dongguan, the first confirmed outbreak of infection source identified, "the culprit" is this mutant strain?
A novel coronavirus pneumonia variant named Delta has recently sounded a new warning for the global epidemic. The new coronavirus, which was first found in India, is becoming a major global epidemic strain. So far, it has spread to more than 80 countries.
In China, delta also appeared in the recent epidemic in Shenzhen and Dongguan. On the afternoon of June 20, the Shenzhen epidemic prevention and control conference revealed that 38 cases of positive cases were reported by ca868 international flight arriving in Shenzhen on June 10, of which 19 cases were highly homologous with the confirmed cases reported on June 14 and 18, all of which were delta variants.
Dongguan also held a press conference yesterday evening. The results of gene sequencing showed that Li, the first confirmed case in Dongguan, had a sample coverage rate of 99.9%, which also belonged to delta strain. It is worth noting that although the gene sequences of Dongguan case and Guangzhou case belong to the same delta strain, there are great differences, suggesting that they are from different sources of infection.
38 cases of positive in an international flight
Comprehensive epidemic prevention by sea, land and air in Shenzhen
As of June 19, 38 positive cases had been reported on the ca868 international flight arriving in Shenzhen from South Africa on June 10. Among them, 30 patients were diagnosed, including 7 confirmed cases of asymptomatic infection and 8 asymptomatic infection.
In view of this situation, Shenzhen immediately took action.
At yesterday's press conference, Shenzhen announced that it would launch a comprehensive epidemic prevention by sea, land and air. Since 0:00 on June 20, the requirement of providing nucleic acid test negative certificate within 48 hours has been added for all passengers leaving Shenzhen and out of the province from Shenzhen airport, railway station, bus station, passenger terminal and other transportation stations.
At the same time, Shenzhen has also announced a new regulation, two types of people's Guangdong health code will be changed from "green code" to "yellow code": one is the people who stay at Shenzhen airport for more than one hour from the entry of ca868 international flight on June 10 to the discovery of Zhu and Xiao's cases on June 18, including the departure or arrival passengers and pick-up and drop off personnel, as well as the airport work and service support personnel; Second, in the residence, work place and activity track of confirmed cases, close contacts and sub close contacts, those who have stayed in the corresponding risk period.
And the "yellow code" will affect users to take public transport in Shenzhen. According to the new regulations announced at the press conference, at present, all stations and buses in Shenzhen Metro network implement code checking, and passengers need to display yuekang code or health code green code before entering the station or taking the bus. However, there is no need to worry too much. If the nucleic acid test result is negative, the system will automatically change the "yellow code" to "green code" after receiving the relevant test data. At present, Shenzhen provides 55 nucleic acid sampling and detection sites for "yellow code" personnel.
Identification of the first confirmed infection source in Dongguan
Nearly 20000 teachers and students are not allowed to leave school
Yesterday evening, Dongguan held a news conference to report that the positive sample of Li, who was diagnosed on June 18 and lives in Baiyue Shangcheng community, was sequenced by the provincial CDC. The results showed that the coverage of the sample was 99.99%, belonging to delta strain. Li is a local case related to the input.
Luo Dong, deputy director of Dongguan CDC, said that the genome sequence of Li was highly consistent with that of his husband Xiao. However, the genome sequence of Li was not in the same branch as that of the Guangzhou epidemic, suggesting that they came from different sources of infection.
1 novel coronavirus pneumonia cases were confirmed in Dongguan yesterday. The newly diagnosed case, 19 years old, studied in Dongguan campus of Guangzhou Xinhua University (located in Machong town), is a resident student of the school. It is reported that there are nearly 20000 teachers and students in Dongguan campus of Guangzhou Xinhua college. At present, the college can only get in and out. All offline teaching is stopped and online teaching is provided.
Machong Town, where the school is located, has also been designated as a closed control area, with all entrances and exits closed. From 6 p.m. on June 20, the third round of nucleic acid testing has been carried out in Mayong.
A suspected novel coronavirus pneumonia was found in Haikou, Hainan today. The man flew back from Dongguan to Shenzhen to Shenzhen. After review, the man's nucleic acid test results were negative, and his current physical condition was normal. And the man lived in the community, adopted closed management, only can not enter, the community will also be full of nucleic acid testing.
How to deal with mutant virus?
Expert: still need to get a vaccine!
To deal with this delta strain, vaccines are still the first choice.
Even in the United States, where the delta virus infection rate is only 10%, President Biden and the director of the Centers for Disease Control and Prevention (CDC) have issued warnings calling for people to get vaccinated quickly. Yang zhanqiu, a professor at the Institute of Virology, Department of medicine, Wuhan University, said on the 20th that the delta strain has only one or two different gene loci compared with the previous variant strain, "it will not affect the protection of the existing vaccine.".
At present, the number of one billion doses of vaccination in China is far less than the effect of mass immunization. Yang zhanqiu said that it is necessary to reach two billion doses of vaccination, that is, about one billion people can be vaccinated, of which about 700 million people or immunity can reach the level of mass immunization.
In response to the question of whether the vaccine is effective for the mutated virus, Professor Wu fan, vice president of Shanghai Medical College of Fudan University, also made it clear in an interview that all vaccines are effective for the mutated virus, and whether they are effective in the future, we will continue to track the virus mutation scientifically.
