South Australia has ticked off one COVID-19 milestone, surpassing a week with no new known cases within the state.

However, health experts say that we still have a way to go if we are to have the widespread restrictions lifted across SA.

28 days is thought to be the target number for no new coronavirus cases, with health authorities using that time-frame to remove the restrictions on the Barossa Valley.

The wine region experienced some of the state’s stricter restrictions after seeing a cluster of cases owing to a tour group.

However, after 28 days of zero new cases, those restrictions have now been removed.

The one-month timeframe is also the period of time recommended by the World Health Organisation, owing to the fact that it represents two of the virus’s 14-day incubation period.
