A returned traveller who tested negative twice to COVID-19 while in hotel quarantine has been confirmed positive two days after leaving hotel quarantine.
The revelation has prompted new public health alerts from NSW Health.
NSW Health recently introduced symptom checking and day-16 COVID-19 tests for overseas travellers who have been released from hotel quarantine.
"The person did not have any symptoms but underwent testing as part of the recently enhanced day-16 follow-up," NSW Health said.
The test results indicated they have a low level of infection, and household contacts have so far returned negative results.
NSW Health believes they acquired the virus overseas and not while in hotel quarantine.
The confirmed case visited a number of venues in and around Wollongong as well as a south Sydney cafe.
Anyone who attended the Headlands Hotel at Austinmer between 1pm and 3pm on Tuesday February 2 or the Bulli Beach Cafe at Bulli between 1.30pm and 4pm on Saturday February 6 should immediately get tested and self-isolate until they receive further advice from NSW Health.
The people at the following venues around the same time are considered casual contacts and should get tested immediately and self-isolate until they receive a negative result. If symptoms appear afterwards, get tested again.
Brighton Le Sands – Mootch & Me: Tuesday February 2 between 10.54am and 12pm.
