At Christmas 2019 I was newly retired and completely unaware of the global pandemic that was already nascent in Wuhan China. The past two years have been a rough, roller-coaster ride. The shock of the initial cases and deaths. Victoria's second wave. The serendipity that flattening the curve managed to achieve the elimination of local transmission. A slower start to mass vaccination in Australia compared with other high income nations. The arrival of the more infectious Delta variant, which proved challenging in NSW and Victoria, and the resulting interstate travel restrictions. And in the past four weeks, the arrival of the even more infectious Omicron variant. Largely as a result of Omicron, 14 per cent of all Australian cases occurred in the past week.
