Hospitalisation is the key metric, that and the long term effects of it all to different groups of our population.
The numbers have dropped, everything has dropped. Cases, and importantly, tests performed. They appear to be down a million (or close) to last week. At 10% positivity, that roughly equates in my head to the drop of around 100K cases. Doesn't it?
Why fewer people are getting tested, I think Ru hit it on the head. Schools out, so there's a big lump of people out. Nearly a million people are off work isolating. Those who have trips booked or are planning to get out are keeping indoors. There will also be a number of people who left as soon as school finished too?
This last push at vaccinating those who are not vaccinated is going to be hard. How do you engage with groups who don't trust you?
