🧵VIC - Outbreak progression

It can be easy to treat the current outbreak in VIC as a single cluster, and compare it to how we expect others to progress. A simple chart like this tells a concerning story of growth:

This thread shows why this outbreak is different 🔽
Transmission is driven by "wild" cases - cases found that were out in the community during some or all of their infectious period. So let's take a look at case isolation status over the outbreak.

It looked like it was going well until the 20th August - what happened?
The answer - new clusters were found (MyCenter child care and Shepparton). And just like at the beginning of the outbreak, there was an initial large jump in cases, and new related cases were not isolating. The Wyndham cluster was also later found.
