Girls walk past a COVID-19 notice board in Melbourne, Australia, Feb. 4, 2021. Play was suspended Thursday at two Australian Open (AO) lead-up events after a hotel quarantine worker tested positive for COVID-19, prompting state officials to reintroduce virus restrictions. Victorian State Premier Daniel Andrews reintroduced the mandatory use of face masks indoors and reduced the number of visitors allowed in private homes as well as postponing a push to get more workers back into offices.
