Melbourne under lockdown again after second coronavirus surge
While the US struggles to contain its first surge of COVID-19, Melbourne, home to nearly 5 million Australians, is on its second lockdown. After getting a taste of some version of normalcy, Melbourne's 5 million residents are barred from leaving their homes except for essential reasons. Borders between Victoria and its neighboring states closed this week. Host Carol Hills speaks with Peter Collignon, an infectious diseases physician and microbiologist, who says the second wave of the coronavirus in Melbourne may have been triggered by a lack of security at the city's quarantine hotels.
