fluTAS reports

Figure 1 is a line graph showing the weekly number of notifications of influenza in Tasmania by year from 2018 to 2022 year-to-date. The horizontal axis indicates the month and 52 weeks of the year. The vertical axis indicates the number of influenza notifications. A separate line on the graph represents the data for each year.

The line for 2018 shows relatively low influenza notification activity with under 10 notifications per week at most times but with slightly higher numbers of notifications from late September to early December with a peak of 27 notifications in October in week 39.

The line for 2019 shows a year of relatively high influenza notification activity. Notifications increased from late February and three distinct peaks in numbers were observed during the year: in April (108 cases in week 16), in July (146 cases in week 28), and in August (176 cases in week 33) before steadily declining to lower levels by November.

The line for 2020 shows some residual influenza activity continuing in the early part of the year but notifications fell to zero in April, coinciding with the implementation of public health measures and social changes relating to the COVID-19 pandemic.

The line for 2021 shows zero influenza notifications across the whole year.

The line for 2022 shows relatively low influenza notification activity in the year to date, with the first cases notified in week 12.
