Australia's Victoria state reports a record 484 virus cases

Australia's hard-hit state of Victoria reported a record 484 new COVID-19 cases on Wednesday and health authorities warned that numbers could continue to rise. With Australia's second-largest city Melbourne now in lockdown for two weeks, authorities had hoped the infection rate would begin to plateau. 

"Certainly we're at a really, really challenging phase of this pandemic," Chief Health Officer Brett Sutton said.

Wednesday's new cases surpassed a previous record of 428 set on Friday.

"We can't necessarily expect numbers to go down. I think that will be an even greater challenge in days ahead. That means that we're going to look at 500-600 cases per day. I absolutely don't want us to go there," Sutton added.

Victoria Premier Daniel Andrews said people had to self-isolate when they became sick. He said nine out of 10 people did not self-isolate between having symptoms and being tested. More than half did not self-isolate between when they were tested and when they got the results. Andrews also announced two more deaths, both men in their 90s, bringing the national death toll to 128. Masks will become compulsory from Thursday for residents in lockdown regions when they leave their homes. Six prisons in Victoria were placed into lockdown on Tuesday after a staff member tested positive at one of the crowded facilities.
