1. Those who live in a high-risk area and return to the sky after 7 days were subjected to centralized isolation medical observation for 7 days, and their nucleic acids were detected on 1, 2, 3, 5 and 7 days respectively; Those who lived in a medium-risk area for 7 days and returned to the sky were observed at home for 7 days, and their nucleic acids were detected at 1, 4 and 7 days respectively. Those who live in low-risk areas for 7 days should complete nucleic acid detection twice within 3 days and do a good job in health monitoring.
2. All personnel returning to the sky should report in advance, track and monitor, push information, and control their whereabouts throughout. "Health code, bank card" and "48-hour (24-hour interval) nucleic acid twice" inspection, and all those who can not provide valid proof will be carried out "landing collection and landing tube".
Strengthen code scanning inspection in key places;
"Sweep and check" all the medical staff who entered the medical institution (that is, scan the place code, check the body temperature, check the health code, check the negative certificate of nucleic acid test within 48 hours), and ask about the 7-day residence history.
