Commun Dis Intell (2018). 2020 Sep 23;44. doi: 10.33321/cdi.2020.44.77.

Cumulatively to 13 September there have been 26,753 case notifications and 674 deaths. The number of new cases reported nationally this fortnight was 764, a 61% decrease from the previous fortnight (1,948). On average this represented 55 cases diagnosed each day over the reporting period, a decrease from 125 cases per day over the previous reporting period. 84% of all cases (640/764) were reported in Victoria, with a smaller number of cases reported from New South Wales (95), Queensland (22), Western Australia (4) and South Australia (3). In Victoria, 97% of cases (621) were locally acquired and were mostly reported from residential aged care facilities; and 3% of cases (19) were reported as under investigation at the date of extract this reporting period. Excluding Victoria, 124 cases were reported nationally, 32% (40) were overseas acquired; 65% (81) were locally acquired, predominantly in New South Wales (62); and 2% (3) of cases were under investigation at this time, all reported in Queensland. The continued decrease in new cases observed this fortnight in Victoria is likely associated with the enhanced public health measures that are currently in place in Victoria. Locally-acquired cases which were predominantly associated with several interconnected clusters continued to be reported in New South Wales. In Queensland, 82% of cases (18/22) were reported as locally acquired from two clusters associated with immigration centres or correctional facilities. A total of 6 deaths were reported from cases diagnosed in this reporting period-all from Victoria, all aged 50 years or older, three male and three female. Although testing rates have declined gradually over the past month they remain high at 14.5 tests per 1,000 population per week. The overall positivity rate for the reporting period was 0.13%. Victoria reported a positivity rate of 0.39% for this reporting period while in all other jurisdictions the positivity rate was 0.05% or lower. For this report, "In focus" is paediatric inflammatory multisystem syndrome temporally associated with SARS-COV-2 (PIMS-TS).

截至9月13日，累计病例报告数为26753例，死亡674例。本两周全国报告的新增病例数为764例，较前两周（1948例）减少了61%。在报告期内，平均每天诊断出55例病例，较前一报告期的每天125例有所下降。所有病例的84%（640/764）来自维多利亚州，新南威尔士州报告的病例数较少（95例），昆士兰州（22例）、西澳大利亚州（4例）和南澳大利亚州（3例）。在维多利亚州，97%的病例（621例）为本地感染，大多来自老年护理机构；3%的病例（19例）在本报告期提取数据时被报告为正在调查中。排除维多利亚州，全国报告了124例病例，其中32%（40例）为境外输入；65%（81例）为本地感染，主要在新南威尔士州（62例）；2%（3例）的病例正在调查中，均在昆士兰州报告。本两周在维多利亚州观察到的新增病例持续减少，可能与该州目前实施的强化公共卫生措施有关。新南威尔士州继续报告主要与几个相互关联的聚集性病例相关的本地感染病例。在昆士兰州，82%的病例（18/22）被报告为与移民中心或惩教设施相关的两个聚集性病例中的本地感染。本报告期内确诊病例共报告了6例死亡——均来自维多利亚州，年龄均在50岁及以上，3男3女。尽管检测率在过去一个月中逐渐下降，但仍保持在每千人口每周14.5次检测的较高水平。报告期的总体阳性率为0.13%。维多利亚州本报告期的阳性率为0.39%，而在所有其他司法管辖区，阳性率为0.05%或更低。本报告的“重点关注”是与SARS-CoV-2时间相关的儿童炎症性多系统综合征（PIMS-TS）。澳大利亚对COVID-19的公共卫生应对措施回顾（截至2020年9月13日）见附录A。
