has been silently blocked for a month, and there are still new cases. What is wrong?

Medical research has been very clear. The new coronavirus is mainly transmitted under the condition of movement of people, causing people to be infected and will not spread through the air to hundreds of meters away, and the incubation period of the virus cannot exceed half a month. Then, if the entire region is silently blocked for one month, the virus should be blocked. Even if there are infected people during this period, they should heal themselves. Then why will there be new infected people in a month of silence?

There is only one possibility, that is, there are still people moving, and the virus is spread through people who can move. So who is flowing? Who can flow? Everyone knows that officials, medical staff, volunteers, security workers and those who can get passes.

Now most people are locked at home, not allowed to leave the house, and do nucleic acid every day. Half a month later, I still regarded these people who did not leave the house as the key targets of prevention and control, so the direction was wrong. At this time, the key management targets should be those who can move. How to manage these people who can move, and have effective measures taken?
