If you go out and spread it people will die...for sure and certain.
Hence the 'stay at home' health orders in Sydney.
The spreading was being done by people in one particular area, wouldn't stay away from their relatives...gave them Covid and killed some of the senior members of the families.
Dear sweet Premier Gladys asked them nicely to stay home [could go out shopping for essentials, exercise, surfing etc.]
They didn't.
She begged them, many took no notice...so she was left with no alternative other than to declare a curfew, mounted police during the day, and cops patrolling night and day. Choppers.
The spreading then declined markedly.
