The government says a cluster of nine coronavirus cases, which happened after several people got together for events in each other's homes, has been contained.
That was identified after investigations from the Contact Tracing Team.
One of those events was attended by someone who broke their isolation after coming to Jersey from a red zone.
That is now being investigated. Anyone who fails to self-isolate as required could be fined up to £10,000.
79 direct contacts have gone into isolation because of this, which may lead to cases being identified in the coming days.
"I want to thank employees across Public Health, Contact Tracing and Enforcement who have prevented a small outbreak from going any further.
"This deliberate flouting of public health advice has led to nine people testing positive so far, and 79 people having to isolate. We will not be able to continue our reconnection plans if this kind of behaviour becomes more prevalent." - Deputy Richard Renouf, Health Minister.
Household mixing is still not allowed in Jersey.
The return of hospitality next week is still going ahead as things stand.
