A mandatory face mask order officially took effect Thursday in Australia’s second-largest city, Melbourne, which has become the epicenter of the country’s rising number of novel coronavirus cases.The mandate is the latest order imposed on Melbourne’s five million residents in an attempt to control the spike in COVID-19 infections.  Anyone over the age of 12 caught in public without any kind of face mask or covering could be fined up to $143, while employers who discourage their workers from wearing a mask face a potential fine of more than $7,000.Premier David Andrews of Victoria state, of which Melbourne is the capital, said the face mask mandate was imposed due to the increase of confirmed COVID-19 infections, and a refusal by residents who tested positive for the virus to isolate themselves.“They have gone out shopping. They have gone to work. They have been at the height of their infectivity, and they have just continued on as usual,” Andrews told reporters.Victoria state posted a single-day record of 484 new COVID-19 cases on Wednesday.  The city is in the second of a six-week lockdown that bans all residents from leaving home unless going to work, school, medical appointments or shopping for food.Cross-border travel between Victoria and the neighboring state of New South Wales has been suspended indefinitely, with the exception of traveling for work, education and medical care.Bicyclists wear face masks at St Kilda beach in Melbourne, the first city in Australia to enforce mask-wearing to curb a resurgence of COVID-19, July 23, 2020.The rising outbreak in Victoria state has sent Australia’s total number of novel coronavirus infections to 13,306 people, according to Johns Hopkins University’s Coronavirus Resource Center, with 133 deaths.Meanwhile, the U.S. reached another grim milestone on Wednesday by recording more than 1,000 deaths for the second consecutive day.
