Some hospitals in South Australia, including Lyell McEwin and Modbury Hospitals, have reintroduced face mask mandates for all staff and visitors due to a new wave of COVID-19 cases. The Northern Adelaide Local Health Network implemented the new rules in all clinical settings but not in public areas. The state has seen a significant increase in reported cases, with numbers tripling since early October. Healthcare workers are being impacted by rising case numbers, leading to an increase in staff furloughing. Authorities are concerned about the elderly and are urging people to wear masks in crowded indoor areas and stay up to date with vaccinations.
