COVID increasing significantly across Canada, a couple of notes:

1. Need intervention now: likely be seeing significant regional restrictions soon.

2. Young people make up large # cases not just because partying. School, wider social networks, work in service industry 1/

3. Testing needs to be stratified, prioritization of those with new sx and high risk exposures etc.

4. Comms experts to target pop'n 20-39--can't rely on docs to do this @BogochIsaac

5. Don't compare daily numbers to earlier. 400 cases in May was likely more like 2000 2/

6. Recognize long-term impact shutting down business: not a health/economy dichotomy. Two are intertwined

7. Vaccine won't be silver bullet. Pandemic likely to continue well in 2021 @zchagla

8. Deaths/hospitalizations late marker of pandemic. If seen, you missed the boat 3/

9. This is not an exhaustive list by any means. More to come. Have to feed my kids. 4/

10. An aerosol dissipates fairly quickly unless there is poor ventilation. In this case, over time, it accumulates. The protection against this is better ventilation. 5/ (iPhone can’t make a new paragraph in twitter. Worst)

11. Indoor gatherings are a big risk factor for COVID transmission. There is a perception this means "young people" having keggers. But it also includes: wedding events, religious ceremonies, card games, dinners etc. Keep these as small, outdoor and spaced out as possible 6/
