SYDNEY (Reuters) -The Australian state of Victoria said on Wednesday a fresh cluster of COVID-19 cases had grown to 15 in three days and that the next 24 hours were particularly critical as some of those infected had visited crowded venues.

An infected person was among some 23,400 people who attended an Australian Football League match on Sunday and officials have ordered thousands of fans to test and self-isolate.
