South Australia has recorded zero new cases of COVID-19, Dr Nicola Spurrier has confirmed in the state’s daily press conference.

On Tuesday, health authorities revealed that two people who were previously thought to have contracted the virus overseas were carrying a strain related to the Parafield cluster.

The total number of cases linked to the cluster now sits at 29, with 38 active cases across the state.

One person, a woman in her 50s remains in hospital. On Tuesday, 9,403 tests were undertaken across South Australia and there are currently around 4,300 people in quarantine across the state.

The good news came as Premier Steven Marshall revealed that the analysis of the Peppers medi-hotel’s CCTV footage where the cluster’s ‘case zero’ was staying had been completed.

The Premier confirmed that there had been no visible wrongdoings by either staff or those staying at the medi-hotel, telling reporters that there had been “no deliberate breach of protocol and no evidence of people being in the wrong place at the wrong time.”
