The site project department failed to find and take corresponding control measures in time.
In the afternoon of April 10, a construction site of a project in Fuyang District stayed with Ran (male), a non migrant worker from a medium and high-risk area.
After the incident, the project has been completely stopped for rectification, and all personnel have been tested for nucleic acid.
On the morning of April 12, it was found that Ran may have contacted with the confirmed case on the high-speed railway in the same carriage in time and space through the big data flow adjustment and precise intelligent control.
Later, it was checked that Ran had not been on the high-speed railway, so the identity of secret connection was excluded.
