Australia back on outbreak alert as state virus infections spike

South Australia reported 14 new coronavirus cases on Monday, a rapid spike in the state’s first outbreak since April, prompting officials to impose social distancing restrictions. The cluster also prompted some other Australian states to reimpose strict quarantine measures on anybody arriving from South Australia - just days after Prime Minister Scott Morrison said he expected all internal borders to be open by Christmas. South Australia authorities first reported three locally-acquired COVID-19 cases on Sunday, saying the outbreak was caused by a worker from a quarantine hotel infecting family members. By Monday, case numbers had jumped to 17.
