Deepen risk analysis to provide data and intellectual support for precision quarantine. Customs big data "cloud" to fight the epidemic

In the fight against the new coronavirus epidemic, in addition to the customs police officers who fight day and night at the ports, airports and passenger inspection channels, the Customs also has a team that dances with the "number" for many years。They strengthened the application construction of big data, focused on strengthening back-end risk analysis, and provided data and intellectual support for on-site prevention and control and precise quarantine。

　　Macro control and drawing of the customs total combat epidemic map

　　To fight a tough battle, we must know ourselves and our enemies。1月25日，习近平总书记在中共中央政治局常务委员会会议上对加强疫情防控作出全面部署后，海关总署闻令而动，利用大数据研判，第一时间全面梳理形成14天内疫情严重地区出境尚未复入境3.A list of 30,000 high-risk travelers。

　　Then, the national customs was mobilized to sort out the information of 1,377 high-risk passengers who had a travel history in severely affected areas and had not yet entered the country from other ports outside the severely affected areas, so as to strengthen the risk prevention and control work of entry-exit passengers at airports across the country。

　　Recently, as the spread of the epidemic abroad has intensified and the risk of preventing import has increased, the customs has timely adjusted the focus of prevention and control, developed and used big data models, carried out monitoring of the epidemic situation in key countries and the situation of inbound and outbound personnel, and timely grasped the risk situation of the entry-exit epidemic。

　　Be able to see and hear the virus

　　In the face of the new situation of epidemic prevention and control, the Customs continues to expand the big data chassis, carry out internal and external big data collision and comparison, dig deep the epidemic import risk points, and urgently launch the travel inspection and control system, and effectively enhance the early perception of the epidemic import risk and early disposal capacity。

　　On February 29, the customs carried out boarding inspection on a flight from Russia, and carried out nucleic acid test on three of them, two of them tested positive for the novel coronavirus. After further examination by local authorities, one was confirmed and the other was suspected。

　　As early as the day before, the customs had received a notification from the national health department and local public security, immediately compared with the customs flight manifest data, accurately locked the flight with the confirmed cases imported from abroad in Iran close contact 3 people, and distributed control in the travel inspection control system。This is the early preparation of the on-site customs officers, waiting for the flight landing, the implementation of quarantine testing。

　　Joint prevention and control to leverage the advantages of data agglomeration

　　In the process of epidemic prevention and control, the customs gave full play to the advantages of data agglomeration, comprehensively strengthened communication and cooperation with public security, immigration, industry and information technology departments, established multiple indexes of passports, ID cards and mobile phones, laid a solid foundation for more accurate targeting and interception of key personnel, and strengthened joint prevention and control efforts。

　　At the same time, the customs strengthened coordination with the Ministry of Foreign Affairs and embassies abroad, focusing on the collection of confirmed cases of Chinese travelers abroad;We will strengthen information sharing with the national and local governments under the joint prevention and control mechanism, obtain information on confirmed cases and close contacts in China, and jointly prevent and control the risk of imported diseases。For example, using the information of confirmed infection cases at home and abroad, focusing on the same passengers on the same flight, comprehensively screening inbound and outbound routes, combing the list of high-risk people who have had close contact with confirmed cases, and controlling those who have not yet entered the country;For those who have already entered the country, local governments will be notified to strengthen follow-up investigation and tracking。

　　In the next step, the customs will closely follow the development of the epidemic situation at home and abroad, further deepen the risk analysis of big data, strengthen the wisdom "brain" of the customs war against the epidemic, enhance the early detection and early disposal capacity of imported risks of the epidemic, and actively serve the overall situation of the national epidemic prevention and control war。
