Where does CDC big data come from?

Big data is based on the signals sent by the base station and received by the mobile phone number card by the three major domestic operators.

Since the outbreak of the epidemic, Baidu has been working closely with China Center for Disease Control and Prevention to help China CDC monitor the epidemic, judge the demand for epidemic prevention science, develop customized tools for secondary structure analysis of viral RNA, and support epidemic prevention and virus research.

On April 24, the cooperation between the two sides made the latest progress. Baidu and the Institute of Viral Disease Prevention and Control of China Center for Disease Control and Prevention (hereinafter referred to as "Institute of Viral Diseases of China CDC") reached a strategic cooperation agreement, and the two sides will jointly set up the "Emergency Technology Center of China CDC-Baidu Gene Sequencing Workstation" to promote COVID-19 virus genome analysis and new vaccine research.

The innovative application of big data in the war epidemic mainly focuses on three aspects:

The first is epidemic monitoring and tracking. In terms of epidemic trend research, epidemiological investigation, public opinion information dynamics, personnel migration and vehicle flow, resource allocation and logistics and transportation, we will develop big data analysis products or services through government-enterprise cooperation to provide real-time dynamic information for the government, enterprises and the public to assist decision-making. Many technology companies across the country have developed their own big data platforms and solutions. Media platforms have used big data technology to draw "epidemic map" and "migration map" to provide convenience for the public to prevent infection.

The second is epidemic prevention. Mining and analysis based on location data and behavior data, high-risk group identification, personnel health tracking, regional risk prediction, etc. Realize accurate identification, accurate decision-making and accurate prevention and control of zoning and grading. Big data also plays an important role in the diagnosis and treatment of diseases, vaccine development, medical research and other scenarios. China CDC and other institutions cooperate with the National Supercomputing Center, BAT and other enterprises to speed up the research and development of vaccines and drugs with the help of the latter's advantages in computing power, algorithms and data.

The third is production and living services. Many Internet, big data companies and online platforms have taken advantage of their advantages to provide residents with online education, online medical care, telecommuting, contactless delivery, online entertainment and other services, and a large number of small and medium-sized enterprises have begun digital transformation. The national government service platform launched the health information code for epidemic prevention and control, and China ICT Institute and three major operators jointly launched the "Communication Big Data Travel Card".

As a voucher for traveling, returning to work, returning to school, daily life and going in and out of public places, it has realized national mutual recognition of health codes and communication codes. Ali "Nail", ByteDance "Flying Book", Tencent Enterprise WeChat and other products provide convenience for telecommuting.
