Covid-19 case numbers are continuing to soar to new records in the United States.  
US correspondent Richard Arnold told Tim Dower the latest daily tally is approaching 500-thousand.  
He says it's causing cancellation havoc. 
“The airline system’s still chaotic, there have been more than a thousand flight cancellations again today, events are being called off, one of the main film festivals leading up to the Academy Awards has just been cancelled.”
