(Fighting New Coronary Pneumonia) Little "two-dimensional code" scans out China's big data "precision epidemic prevention"

China News Agency, Kunming, March 1st (Miao Chao) Under the new crown pneumonia epidemic, square and circular two-dimensional codes can be seen everywhere in China. Countless small "two-dimensional codes" have woven dense big data "epidemic prevention networks" to improve With the accuracy and timeliness of retrospective work, it supports China's "precision epidemic resistance".

In Kunming, Yunnan, reporters are walking in the streets, whether it is residential quarters, farmers' markets, large supermarkets, hospitals, pharmacies, subways, buses, airports ... need to scan the QR code with a mobile phone to enter and exit.

The public understands this. Wu Mei, a citizen of shopping at Carrefour Supermarket in Kunming, stated that "scanning a QR code is both responsible for the health of others and a protection for himself."

In the early days of the outbreak, Yunnan ’s local prevention and control of the epidemic relied on person-to-person carpet inspections and road temperature measurement to register body temperature and travel information. This traditional method of registering with paper uses daily data collection and subsequent summary use. Time consuming.

On February 11, Yunnan decided to launch a "code scanning operation" in public places. All personnel entering and exiting public places must cooperate with the mobile phone to scan the "Yunnan Anti-epidemic QR Code". If you refuse to cooperate, public places will refuse to enter and exit. .

Nine days later, a new confirmed case of neonatal pneumonia was added to Yunnan. The mobile phone number of the case was entered into the scanning system in only 30 seconds, and 204 persons who may have had contact with it were screened out.

"Everyone scans the QR code before entering or leaving public places, so that people's activities in public places can be effectively recorded." Said Liu Yuewen, leader of the Big Data Expert Group of the Yunnan Provincial Public Security Department and associate professor at the School of Management of Xi'an Jiaotong University. Confirm the case, big data can quickly trace back to the place where the patient has come and go, so as to quickly and accurately find people who may have contact with them.

In the prevention and control of the new crown pneumonia epidemic, Heilongjiang, Shandong, Shanxi, Hebei and other places have changed the traditional method of warfare to big data war "epidemic", and posted the QR code registration information on the travel of people in public places and residential areas.

Liu Yuewen said that using the big data formed by the QR code for analysis can also calculate the probability index of each person's infection with the new crown virus, "and alert high-risk personnel without touching personal privacy."

With the resumption of production and resumption of work, problems such as difficulty in identification and access to the epidemic prevention and control in various places have arisen. Zhejiang is the first nationwide to use big data to research and launch a "health code", which uses red, yellow, and green three-dimensional QR codes to dynamically display the risk level of individual outbreaks. Those who display the "green code" can pass directly, and those who display the "yellow code" and "red code" need to accept corresponding isolation measures.

After Zhejiang, Chongqing, Henan, Hubei, Yunnan and other places have successively introduced "health codes". At present, the health codes for epidemic prevention and control in many provinces have achieved mutual recognition across provinces.

The reporter learned from Lufeng County, Yunnan that Lufeng County is currently guiding rural laborers to go out for employment. The local workers have entered a "health code" for each migrant worker, including their personal health conditions such as temperature measurement during their stay in Lufeng. "Code" can keep the health information of the staff. (Finish)
