The Beijing Health Commission alerted residents not to leave Beijing unless necessary amid flare-ups, and asked residents who have not returned to Beijing to postpone the schedule.
If there is "time and space overlap" with the travel schedule of the reported cases, please report your travel schedule to the community (village) work unit and hotel immediately, stay in self-isolation and cooperate with various control measures, the commission said on Monday.
People who have not returned to Beijing should postpone their return schedule and cooperate with local prevention and control measures, Beijing Health Commission said.
Media learned from the commission that the "time and space overlap" specifically refers to the same community, supermarket, station and airport, etc. Mobile phone numbers that intersect within a certain area of the same base station at a certain time are also recorded as space-time crossings.
Epidemiologists said the reason why Beijing adopted such prevention and control policies is that the flare-up this time features overlapping networks.
Beijing had already tightened its access policy last week. Xu Jianhe, the spokesperson for the Beijing municipal government, said on October 25 that people in county-level regions with one or more local COVID-19 cases and travel history in the county within 14 days are strictly restricted from entering and returning to Beijing, and they will not be given a green code for access.
People from other county-level regions in prefecture-level cities with at least one local COVID-19 case should not return to Beijing unless necessary. Those who really need to come to Beijing must present the green code and a negative nucleic acid test within 48 hours before boarding and should undergo health monitoring for 14 days, Xu said.
