But new tests carried out on this intriguing "cluster" revealed that only four of these people were ultimately carriers of the coronavirus.

Checks are underway to understand the process that led to the erroneous results of these PCR tests, which are considered reliable.
Passengers will finally be able to take off for Shanghai.
