The ABC understands that a second worker at Sydney’s Royal North Shore Hospital has tested positive to COVID-19.
Yesterday, an unvaccinated 24-year-old student nurse who worked at both Royal North Shore Hospital and Fairfield Hospital tested positive.
A hospital source has told the ABC about the infection, which NSW Health has not yet officially confirmed.
Chief health officer Kerry Chant yesterday said the wards where the 24-year-old female had worked from June 24 to June 28 were locked down and discharged patients were being contacted by NSW Health.
The cardiology and a general abdominal surgery wards at Royal North Shore Hospital were affected, along with Fairfield's rehabilitation ward.
They are no longer admitting any new patients.
"We know that the student nurse worked whilst infectious on a number of days, and obviously immediately our health team swung into action," Dr Chant said.
"We are also arranging testing for any staff that may have come in contact."
More than 100 staff and patients have been identified as close contacts.
Families of patients who may have visited the wards were contacted by NSW Health who said all steps were taken to keep staff and patients safe.
The hospitals remained open after the affected areas were cleaned and sanitised.
The second infection at the hospital comes after NSW recorded 22 cases of COVID-19 on Wednesday.
Greater Sydney, the Blue Mountains, Central Coast, and local government areas of Wollongong and Shellharbour have been in lockdown since the weekend.
Yesterday, NSW Premier Gladys Berejiklian hinted the two-week lockdown imposed on several parts of the state would not need to be extended if infection numbers remained steady.
The Premier also announced QR code check-ins would be mandatory in supermarkets, schools and offices from July 12.
Only teachers and visitors will need to check-in in schools.
"If we continue to do the right thing, if we make sure we are following the health advice, that we can get out of this is the time-frame we've described, but that depends again on the next few days," Ms Berejiklian said.
