Recently two of the four cases tested positive but at time of testing asymptomatic were in fact pre-symptomatic, and have since shown symptoms.

Were these in the community testing programme, or from the travel testing? Or both? How many people have been asked to self-isolate through contact tracing with those two individuals?


One of the pre-symptomatic cases referred to was identified through border testing and the other identified through community testing.

The following table shows the number of direct contacts who were required to isolate.
