Nationally, there was a continuing downward trend in notifications of COVID-19. The daily average number of cases for this reporting period was 14 compared to an average of 23 cases per day in the previous fortnight. There were 192 cases of COVID-19 and no deaths this fortnight, bringing the cumulative case count to 27,344 and 892 deaths. While the majority of cases in this reporting period were from Victoria (60%; 116/192), this represents a continued decrease in cases in this state resulting from the public health interventions. During this fortnight, 66% of all cases (127/192) were reported as locally acquired, with the majority reported from Victoria (108/127). The highest proportion of overseas-acquired cases were reported in New South Wales (75%; 38/51), followed by Western Australia (22%; 11/51). Although testing rates declined, they remain high at 9.2 tests per week per 1,000 persons. There was variability in the testing rate by jurisdiction, with testing rates depending on the epidemic context. The overall positivity rate for the reporting period was 0.05%, with Victoria reporting a positivity rate of 0.08% for this reporting period. In all other jurisdictions the positivity rate was ≤ 0.06%.

Cumulatively to 27 September there have been 27,095 case notifications and 835 deaths. The number of new cases reported nationally this fortnight was 278, a 67% decrease from the previous fortnight (841). On average, this represented 20 cases notified each day over the reporting period, a decrease from an average of 60 cases per day over the previous reporting period. 82% of all COVID-19 cases for the period (229/278) were reported in Victoria, with smaller numbers of cases reported from New South Wales (32), Western Australia (9), Queensland (6) and South Australia (2). In Victoria, 92% of cases (210/229) were locally acquired with known source, 7% (15/229) were locally acquired with unknown source, and 2% (4/229) were reported as under investigation. Excluding Victoria, there were 49 cases in other jurisdictions. Of these, 69% (34/49) were overseas acquired, 18% (9/49) were locally acquired, and 12% (10/49) were under investigation at this time. The continued decrease in new cases observed this fortnight in Victoria was the result of the public health interventions to minimise transmission. A total of 8 deaths were reported from cases diagnosed in this reporting period, all of whom were >75 years old, and all from Victoria. Although testing rates declined over the past month, they remain high at 10.4 tests per 1,000 population per week. There is variability in the testing rate by jurisdiction; the rate depends on the epidemic context. The overall positivity rate for the reporting period was 0.08%. Victoria reported a positivity rate of 0.18% for this reporting period, while in all other jurisdictions the positivity rate was 0.05% or lower.

BackgroundAs the epidemic of COVID-19 is gradually controlled in China, a summary of epidemiological characteristics and interventions may help control its global spread.MethodsData for COVID-19 cases in Hubei Province (capital, Wuhan) was extracted until 7 March 2020. The spatiotemporal distribution of the epidemic in four periods (before 10 January, 10–22 January, 23 January–6 February and 7 February–7 March) was evaluated, and the impacts of interventions were observed.ResultsAmong 67 706 COVID-19 cases, 52 111 (76.97%) were aged 30–69 years old, and 34 680 (51.22%) were women. The average daily attack rates (95% CI) were 0.5 (0.3 to 0.7), 14.2 (13.2 to 15.1), 45.7 (44.0 to 47.5) and 8.6 (7.8 to 9.3) cases per 106 people in four periods, and the harmonic means (95% CI) of doubling times were 4.28 (4.01 to 4.55), 3.87 (3.78 to 3.98), 5.40 (4.83 to 6.05) and 45.56 (39.70 to 52.80) days. Compared with the first period, daily attack rates rose rapidly in the second period. In the third period, 14 days after 23 January, the daily average attack rate in and outside Wuhan declined by 33.8% and 48.0%; the doubling times increased by 95.0% and 133.2%. In the four periods, 14 days after 7 February, the daily average attack rate in and outside Wuhan decreased by 79.1% and 95.2%; the doubling times increased by 79.2% and 152.0%.ConclusionsThe public health interventions were associated with a reduction in COVID-19 cases in Hubei Province, especially in districts outside of Wuhan.

The Impact

The study characterized the transmission of COVID-19 in Ghana by estimating the time-varying reproduction number (Rt) and exploring the effect of various public health interventions at the national and regional levels. The median Rt for Ghana and six out of sixteen regions dropped from greater than 1 in March 2020 to less than 1 in September but increased above 1 in January 2021. The relaxation of movement restrictions and religious gatherings were not associated with increased Rt in the regions with lower case burdens. However, Rt increased in most regions after schools were reopened in January 2021. In a regression analysis, we estimated that the per-capita cumulative case count increased with population size. Findings indicated the public health interventions reduced the Rt at the national level while at the regional levels, the Rt fluctuated, and the extent of fluctuation varied across regions.
