SYDNEY (AP) — Coronavirus cases are surging across Australia as an outbreak of the omicron variant spreads, prompting Prime Minister Scott Morrison to schedule an emergency national cabinet meeting. The surge has already overwhelmed testing stations, prompted new vaccine mandates and caused at least one state to cut back on elective surgeries. New infections in Sydney and surrounding parts of New South Wales state skyrocketed on Wednesday to more than 11,000, up from 6,000 a day earlier. More than three-quarters of Australians are fully vaccinated, and just how deadly the latest outbreak will prove remains to be seen. Australia has so far avoided the worst ravages of the pandemic, reporting a total of 2,200 virus deaths among its population of 26 million.
