How do you know the index case less than 24 hours after it all kicked off?
Without a known infection source, you don't as the first case found is often not the index case.
ie
Al-Taqwa teacher first found case in current cluster. But testing since has indicated that she was not infected first. Plus the person who infected that person is still not known. It may or may not have been a person infected by the Traffic Controller, which while probably the most likely scenario it could also not be.
Melbourne's first Delta Cluster ( North Melbourne) was found via Camping Man. He was not the first community case though as later tests found the people that infected him. The link back beyond that to a person in HQ with the same strain was never found (ie HQ Breach, Airport Arrival Breach, Aircraft Cleaning Breach?)
