Australia announced on Wednesday 501 new cases of coronavirus, is the highest figure since the arrival of the pandemic on the island-continent.
The vast majority of cases have been identified in the past 24 hours in the State of Victoria (south), where the authorities are battling major outbreaks in Melbourne and its suburbs, which are submitted for almost two weeks to new measures of containment.
The previous peak of the epidemic was dated 28 march, when 459 cases had been registered, according to figures compiled by AFP.
The country was subsequently able to contain the spread of the virus, to the point that the restrictions had been lifted.
On Wednesday, the Premier of Victoria Daniel Andrews has made state-of-484 new cases and two new deaths.
Australia now totals nearly 13 000 cases of COVID-19, a disease that has been 128 deaths in this country of 25 million inhabitants.
As of midnight Wednesday evening, the inhabitants of Melbourne will be required to wear a mask when they go out of their homes, at the risk of hurt if they do not have a fine of 200 australian dollars.
But Mr Andrews has estimated that changes in behaviour were needed. A study has shown that 90% of patients diagnosed in the past two weeks had not had the reflex to isolate between the time where they had felt symptoms, and where they had done a test.
This new wave of cases hit the hopes of a quick economic recovery in a country which is expected to see its first recession in 30 years, due to the coronavirus.
Investigations made public this week showed that the recovery of the epidemic was probably related to shortcomings in the hotels where the people back in Australia to conduct their quarantine.
The neighbouring states have closed their borders with Victoria, but cases have, however, been detected in New South Wales.
