Closed-loop management of epidemic situation refers to a management mode of point-to-point docking. Except for the whole body protection personnel, other personnel have no contact and no social activity track. In the process of closed-loop management, flow regulation mainly plays two roles. First, investigate and understand the movement track, people and places contacted by infected people from outside the province when they return to Guizhou, and promptly notify relevant brother provinces to follow up and investigate relevant risk personnel.

The second is to investigate the people and places that infected people come into contact with after entering Guizhou, judge whether there is risk spillover in the process of closed-loop management according to the information such as protection during contact, and put forward corresponding control measures and suggestions. Through these two aspects of work, we can judge the high-risk groups more accurately, control them in time and prevent the spread of the epidemic.

Matters needing attention

Everyone should continue to adhere to the "three-piece" epidemic prevention (wearing a mask, keeping a social distance and paying attention to personal hygiene), earnestly enhance personal protection awareness, and do a good job in self-health monitoring. After COVID-19's suspected symptoms such as fever, sore throat, dry throat, myalgia and cough appear, do a good job in protection and seek medical advice in time. In addition, we should actively cooperate with the government to implement various prevention and control measures and strengthen the vaccination work in COVID-19.
