The Canada Day long weekend (beginning of July) coincided with the easing of a number of restrictions as we moved into Phase 3 of reopening. Kelowna is a small city of 250,000 in the interior in lake country. The Okanagan lake system stretches down through BC and into Washington State, remnants of what was a massive lake during the last Ice Age. From a single social gathering there emerged first right COVID cases, and then eventually 30 COVID cases.
For people that don't know what contact tracing is, and why a systematically planned out and coordinated contract tracing strategy is important, consider this. From those 30 cases, there are now 1,000 people who are in 14 day self-isolation/quarantine. That's how the virus is contained from community spread.
