For those exposed without effective protective measures, their health code is generally red for close contacts. For close contacts, the management measures of "7-day centralized isolation +3-day home health monitoring" will be adjusted to "5-day centralized isolation +3-day home isolation", during which code management will be implemented and they are not allowed to go out.
On 1, 2, 3 and 5 days, medical observation was concentrated and 1 nucleic acid was detected respectively. On 1 and 3 days, medical observation was isolated at home and 1 nucleic acid was detected respectively. Timely and accurately judge close contacts, and no longer judge close contacts.
Close contacts refer to people who need centralized or isolated medical observation and management at home, and their health codes are generally displayed in red. At the same time, the health codes of people with positive nucleic acid test, confirmed cases, asymptomatic infected people, suspected cases, close contacts of close contacts, outsiders and people who lived in China's medium and high-risk areas in the past 14 days are also red. At the same time, in the process of emergency response, the health codes of other high-risk groups that need emergency tracking and isolation management are also red.
Close contacts need centralized isolation medical observation 14 days, four times of nucleic acid detection are needed during centralized isolation medical observation 14 days, and 1 times of nucleic acid detection are needed on 14 days respectively. In addition, close contacts should be monitored at home for 7 days after they are released from isolation. During this period, their body temperature and symptoms should be monitored to reduce mobility. Personal protection should be done when going out, do not participate in gathering activities, and conduct a nucleic acid test on the second and seventh days respectively.
