BEIJING — Authorities in the eastern Chinese port city of Qingdao say they have completed coronavirus tests on more than 3 million people following the country’s first reported local outbreak of the virus in nearly two months.

The city’s health department said Tuesday that no new positive cases had been found among the more than 1.1 million test results returned thus far. The city said it had a total of 12 cases, six with symptoms and six without, since the new outbreak was first spotted over the weekend at a hospital.

The National Health Commission, however, said Tuesday that at least six new cases of the virus were found in Qingdao in the past 24 hours.

The reason for the discrepancy was not immediately clear.

The National Health Commission numbers released Tuesday reported a total of 30 new virus cases in the previous 24 hours nationwide. It broke down those numbers into 13 cases in which people had symptoms and 17 cases in which they had no symptoms. The total number of locally transmitted cases, both with and without symptoms, was 11, while the rest were listed as imported.
