Using Bluezone helps detect close contact with suspected infected people, contributing to the prevention and control of Covid-19 epidemic. The Center is headed by Mr. Do Cong Anh, Deputy Director in charge of the Department of Informatization (Ministry of Information and Communications); leader of Information Technology Department (Ministry of Health) as Deputy Director; Mr. Tran Dac Phu, consultant of Vietnam Public Health Emergency Response Center is a member, in charge of professional advice. In addition, the Center has 6 other members from functional units of the Ministry of Information and Communications and information technology enterprises. In particular, the leader of Bkav Group is in charge of the overall design of shared platforms and databases… The Center has the task of acting as a focal point, coordinating with agencies, organizations and enterprises, participating in technical and technological support and cooperation to serve the prevention and control of Covid-19 epidemic; design, build, manage, operate, monitor, ensure safety and network security for technology platforms and systems for Covid-19 prevention and control. In particular, the Center will uniformly manage, centrally connect and distribute electronic health declaration data, domestic movement declaration data, people’s reflection data, quarantine point data and data on control of entry and exit of quarantine points between Covid-19 epidemic prevention and control technology systems… Step 1: Visit https://www.bluezone.gov.vn or download directly at App Store or CH Play. Step 2: Once downloaded, the application will ask for permission to use Bluetooth to record contact with other Bluezone installed users. If Bluetooth is not open, drag the status bar and turn on Bluetooth; or go to Settings, select Bluetooth and turn it on. Step 3: Once the installation is done, click Scan Around. If someone near you less than 2m has used Bluezone, the application will automatically identify these users and put them in the contact list.

Assoc. Prof, Dr. Tran Quy Tuong, Director of the Department of Information Technology, Ministry of Health, said that technology solutions are the optimal choice for the current epidemic prevention and control in quickly tracking F0, setting up F0. list F1, F2. Bac Giang and Bac Ninh are two hot epidemic centers when the epidemic enters the industrial zone. The number of cases is increasing day by day, there is no sign of cooling down, the ratio F1 to F0 is very large. The Ministry of Health has mobilized more than 2,000 health workers and is continuing to mobilize to support these two provinces. According to Mr. Tran Quy Tuong, for the current epidemic prevention and control, it is very important to quickly trace F0 and make a list of F1, F2 to control the spread of the disease. For areas with a small number of cases, medical staff and other forces can be traced. However, when the number of cases increases greatly, there will not be enough human resources to carry out direct contact tracing in the area. And at this time, the technology solution is the optimal choice. Regarding electronic tracing, we currently have two main data sources, which are from the Bluezone application and the Medical Declaration Management Information System. Bluezone allows to record close contacts between smart mobile phones that install and use Bluezone. The medical declaration management information system includes medical declaration information, travel schedules and travel history to places of people. In order to quickly track down, the Information Technology Department has supported Bac Giang and Bac Ninh to apply information technology in epidemic prevention and control. Mr. Tran Quy Tuong said that in Bac Ninh, the Department of Information and Communications advised the Provincial Steering Committee to set up an Information Analysis Team to analyze data sources, propose tracing, testing and assessment. assess the risk of spread, make timely recommendations in disease prevention and control. The messaging system was built to quickly and promptly deploy the instructions of the Provincial Steering Committee to members of the Community Covid Team. For workers, the Management Board of Industrial Parks has coordinated with the Department of Information and Communications to develop information management software for all workers in industrial parks, helping to manage, monitor and trace quickly when there are cases in industrial zones; and provide timely data for direction and administration. According to statistics from the Medical Declaration Management Information System, the total number of medical declarations in Bac Ninh up to June 1 was 1,059,179. In Bac Giang, in the face of complicated developments of the Covid-19 epidemic, on May 22, 2021, the Chairman of the People’s Committee of Bac Giang province issued a launching document and asked all people in the province to declare 2nd time to help authorities monitor and manage cases with epidemiological factors, and promptly detect people suspected of being infected with Covid-19. After three days, there were 456,080 medical declarations recorded in the system out of a total of 881,400 medical declarations of the whole province. On May 22, with the support of the Information Technology Department, the Ministry of Health, the province established an electronic monitoring and tracing team consisting of 15 members from the Department of Health, the Center for Disease Control of the province and the province. group. The members of the Team have been given accounts and trained to exploit data from the Medical Declaration Management Information System for monitoring and tracing. As of June 1, 2021, the Team has made 3,976 calls for people to declare health with symptoms or epidemiological factors, instruct people on measures to prevent and control the epidemic suitable for each person or transfer information for commune and district levels to verify and handle directly. Especially based on the system’s information, the Team has detected 66 F1 cases currently isolated at home and has transferred the information to the district level for management according to regulations. On May 29, 2021, the Ministry of Health issued Decision No. 2666/QD-BYT on the issuance of Guidelines for the use of medical declaration and close contact detection applications for the prevention and control of the covid epidemic. -19, one of the important purposes of this decision is to support the implementation of electronic medical declarations to help manage, monitor health and detect cases early for effective disease prevention and control. Covid-19. If people and agencies and units strictly follow the instructions of the Ministry of Health, when there is a case of F0, the tracking and listing of F1, F2 will be very quick and timely. As of May 31, Bac Ninh province 578,143 people install and use Bluezone application on smartphones, accounting for 42.24% of the province’s population, ranking 2nd among 63 provinces and cities nationwide; The province has 10,519 establishments that make up QR codes from the health declaration system for people to check in with the Bluezone application. Through checking the checkin data at the office, quarantine checkpoints, industrial parks, accommodation facilities, the number of check-ins is quite large. As of May 31, 2021, Bac Giang province There are 480,306 people installing and using Bluezone application on smartphones, accounting for 26.63% of the province’s population, ranking 9th out of 63 provinces and cities nationwide.

Always wear a mask, open the Bluezone app, declare health when going to public places. Accordingly, for technologies that are promoting effective epidemic prevention and control, it is necessary to change and switch from voluntary encouragement to compulsory installation of some basic applications. THREE “Attack” against COVID-19 Currently, there are three “attacks” to prevent the Covid-19 epidemic: Increasing testing on a large scale, implementing a vaccine strategy and applying technology for tracing. In particular, the use of technology chaired by the Ministry of Information and Communications is promoting effectively. Deputy Minister of Information and Communications Nguyen Huy Dung said that the new approach from the Prime Minister’s point of view is a harmonious combination between prevention and attack. Previously, medical declaration applications for epidemic prevention and control, and support for tracing only recommended people to use, but now will become mandatory. Second, anti-epidemic data sources must be centralized in one processing hub. Previously, because people declared through different applications, the data was scattered. Now the data must be centralized so that advanced and modern technology can be applied to perform the analysis to produce the required results. Mr. Nguyen Truong Nam, Deputy Director of the Information Technology Department (Ministry of Health), said that for the health declaration for the entire population, people can declare through 3 applications: NCOVI, Bluezone and Vietnam Health Declaration. Specifically, Vietnam Health Declaration is a software of the Military Telecommunications Industry Corporation (Viettel), so the declared data is stored at Viettel. Data declared by people on Bluezone (of Bkav Technology Group) and NCOVI (of Vietnam Posts and Telecommunications Group – VNPT) are stored centrally at the Department of Informatization (Ministry of Information and Communications). After being collected, the medical declaration data will be collected by the Centers for Disease Control and Prevention (CDC) in provinces, agencies and units according to their competence. This data is used for control, analysis and case tracing. Meanwhile, many units still use paper declaration and electronic declaration in parallel. Faced with the fact that medical declaration data is still scattered, the Information Technology Department (Ministry of Health) is working with units to promote data interoperability and build a centralized medical declaration database. central, connected. INSTALLATION AND USE OF THE APP WILL BE REQUIRED According to experience from previous infections, the next epidemic is more difficult, complicated, unpredictable than the previous one, the consequences are more severe, the treatment is more difficult, and the impact is worse. At the Government Standing Meeting on Covid-19 epidemic prevention a few days ago, the Prime Minister noted: currently the number of new infections and deaths on the world epidemic map continues to increase; illegal entry and residence tend to be more in recent times; appeared subjective, negligent and unwary thoughts of many localities, agencies, units and people; centralized isolation management, after isolation (when returning to the locality) is still inadequate; The new strain of the SARS-Cov-2 virus spreads quickly, is difficult to detect, and has complicated developments. It is predicted that the epidemic situation will continue to be complicated, it will be long, it is not possible to confirm the time when the epidemic will end. Therefore, we must be ready to deal with the epidemic at the highest level, and we must live safely while the epidemic is still around us. Following the direction of the Prime Minister, the Ministry of Information and Communications has issued the document “Guide to use the set of solutions to support Covid-19 prevention, control and tracing in the community”. This set of solutions includes Bluezone (a close contact warning application for suspected Covid-19 patients), NCOVI (voluntary health declaration management system), medical declaration for people on entry, and a system to record people coming and going to public places (via QR code scanning) and Covid-19 safe anti-epidemic map system. Currently, there are 9 provinces and cities nationwide that have implemented Covid-19 epidemiological information mapping software (called CovidMaps). The CovidMaps map allows real-time monitoring of the epidemic situation in Da Nang, Bac Giang, Vinh Phuc, Bac Ninh, Quang Ninh, Quang Nam, Gia Lai, Phu Yen and Lang Son. The Covid-19 epidemiological information map (CovidMaps) helps the community to visually monitor epidemiological information of local cases via the Internet, the government has more digital technology solutions to serve management and control. practice in epidemic prevention and control. According to the information in the document “Guidelines for using a set of solutions to support Covid-19 prevention, control and tracing in the community,” if 60% of adults install the Bluezone application on their phones, the reported data about cases of close contact, contact with people with Covid-19 will reach an almost absolute level of accuracy. Therefore, in order to promote effectiveness in epidemic prevention and control, it is necessary to join hands to use and voluntarily declare accurately information of the people and the community. Many people think that installing and using the application will become a mandatory requirement, like wearing a mask. For industrial parks and factories, the Ministry of Information and Communications has proposed that people working in industrial parks, factories and enterprises must install the Bluezone application and the NCOVI medical declaration application. .
At public places, offices need to scan QR Codes to be able to collect digital data on the system to record arrivals or departures at public places. In addition, any citizen when going to crowded places needs to install the Bluezone application, to be able to detect close contact with infected people (data already stored on the system). The Government Office issued Official Letter No. 3440/VPCP-KGVX to the Ministry of Health and the Ministry of Information and Communications with the content considering the proposal of the Ministry of Information and Communications on the implementation of a number of information technology applications and Connecting surveillance cameras to support the prevention and control of the Covid-19 epidemic. Persons subject to medical supervision and isolation must declare mandatory information on the application. This mandatory also requires the awareness of the community not only to install the application on the mobile device, but to enable the connection for the application to work. Moreover, using Bluezone and turning on Bluetooth when going to public places, when exposed to large numbers of people, will help people protect themselves and the community, and at the same time help in zoning out the epidemic and tracing it quickly. . When a Covid-19 patient is detected, only those at high risk are quarantined instead of isolating everyone involved. The Ministry of Information and Communications has just sent an official dispatch to the People’s Committees of the provinces and centrally-run cities and the Departments of Information and Communications of the provinces and cities about the implementation of the surveillance camera system at the agencies. centralized isolation facility to prevent Covid-19.
