Innovation helps stop COVID-19 at China's borders
"Ding!" It's the sound of Customs officers scanning the electronic health codes of travelers in the exit-entry hall before allowing them into the country.
China's border ports are the main battlefield in the control of imported COVID-19 cases.
All airlines have posted health declaration QR codes at check-in counters and boarding gates of all flights to China so passengers can fill in their health information on the WeChat Mini-Program or declaration app, according to the General Administration of Customs (GAC).
As of April 8, the number of health declarations on the mini-program was about 3.69 million, with about 7.82 million page views and 1.96 million WeChat users. Declarations on the website and app totaled about 119,000.
The testing laboratory is also a battlefield. With the continuous rise in imported cases, the GAC has fully mobilized and integrated its detection capabilities, and deployed detection personnel and equipment to frontline quarantine work.
Much-needed detection equipment was added, including 40 nucleic acid extraction instruments, 39 fluorescence quantitative PCR instruments, and five new P2 laboratories.
Specialists conduct difficult molecular biology tests for more than 10 hours a day in the Customs laboratory under the protection of relatively high biosafety .
In addition, the GAC has strengthened big data risk analysis in cooperation with the foreign affairs, industry and commerce, health, immigration and civil aviation authorities.
Customs personnel kept a close eye on key countries, key flights and key passengers based on big data technology.
