Jump in Shenzhen Covid-19 cases puts Hong Kong border hopes on hold
- Long-awaited reopening to mainland hinges on getting latest outbreak under control but updated numbers show a doubling within 24 hours
- Close contact tracing has identified all 13 cases so far and all share the same chain of transmission

Another new case was reported late on Wednesday and there are now 13 infections in total, all belonging to the same chain of transmission, the Shenzhen Health Commission said.
The Shenzhen outbreak started on Friday, when routine screening picked up the Delta variant in a married couple.
Two of the latest cases are from the same family which was included in Tuesday morning’s briefing, bringing the total number of members affected to five. All were either close contacts of previous confirmed cases or had visited the same places.
They were picked up through testing of close contacts of previous cases and key populations, the health commission said.
The city’s 12.5 million residents have completed one round of compulsory mass screening with a second round under way. Meanwhile, a number of public parks in Shenzhen are closed and restrictions have been placed on residents in Luohu and Longgang, where the confirmed cases live.
