Two-pronged virus tracing in Beijing underway: expert

The COVID-19 outbreak in Beijing, which took place after 56 days without new cases, indicated that the novel coronavirus was brought from outside into Xinfadi wholesale market, the latest source of new cluster infections, said Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention said during an interview with CCTV on Friday.

It is difficult to pin down the source, Wu said. The tracing process has been implemented from two aspects: people and goods transported to Xinfadi market.

Additional investigations into early cases are underway to address two questions, said Wu. The first is for those who worked in and visited Xinfadi market, how come some got infected while others did not. The second is to determine whether the virus was brought by people or by objects.
