| SvennoJ said: I'm wondering what's going on here atm. We didn't do anything new apart from a couple counties making masks mandatory indoors while opening up nearly everything else. The reported cases suddenly started dropping, today only 33 in Ontario (although still 15K pending tests). Great but how did we go from a 160 average to 33 in 3 weeks while opening up things and mobility trends further increasing. A week ago we were still over 100 average. |
With a low number of cases contact tracing is a very effective tool. But you need people doing the footwork. East asian countries like Vietnam, South Korea or on the other side of the world cuba have poured a lot of people into contact tracing. This works well enough. But if the case count increases, the people doing the tracing are overwhelmed. So you need additional measures. That Canada reduced it's cases further after opening can probably be accounted to contact tracing. Also keep in mind, that found new infections were usually infected a few days before. Usually between one and two weeks before they find their way into the statistics. So even after opening up numbers may still drop from fewer infection from before the opening.
