- Only 19% of cases that came into New Zealand resulted in more than one additional person being infected while 24% led to a single additional infection - presumably policy substantially reduced transmission;
- Lockdown reduced R-naught of our biggest cluster from 7 to 0.2 within a week;
- The 649 cases analysed showed 277 separate introductions of the virus into New Zealand;
- There is no evidence of the virus circulating before the first reported case on 26 February;
- The largest cluster came from the US, and North America provided most of the cases resulting in transmission linkages.
I was very worried in February that it had already gotten here. Somehow, it hadn't. We've been very lucky.
Oh, and obviously, lockdown worked.
