/41
@BIRcovidhealth @GovCanHealth Remember, the forecast reflects not only recent input data, but also numbers expected for the next 2 weeks, based on 5-week average trends.
The next forecast will be August 26, 2023. You should assume infections in your region are increasing when making decisions.
/42
@BIRcovidhealth @GovCanHealth In this surge, infections seem to be increasing fastest first in western provinces. Central and Eastern provinces should expect that infection numbers as high as estimates for Western provinces may start happening in the coming weeks.
/43
@BIRcovidhealth @GovCanHealth I’m not very sure about where things will go in the coming weeks. We could see a surge that increases quickly but tops out quickly too, as we’ve seen for much of the last 6 months.
/44
@BIRcovidhealth @GovCanHealth We could also be starting the annual upward climb in excess mortality that starts in July and peaks around December.
I don’t “think” we’ll see the excess mortality of 2022, but it will almost certainly remain higher than excess mortality in 2020 and 2021.
/45
@BIRcovidhealth @GovCanHealth I would still hold out for a fall XBB-based vaccine, but be very careful about avoiding exposure until these are available, ESPECIALLY if you have not yet been infected.
/46
@BIRcovidhealth @GovCanHealth Take care of yourselves and others. Look for the helpers and be a helper.
And if you’re in an essential place, especially a healthcare setting, please, please wear a mask to protect those at higher risk. You can act before healthcare settings finally do.
/47/fin
@kraftmcdinner @BIRcovidhealth @GovCanHealth BC may also have a policy about excluding hospital outbreak cases from hospital numbers. They excluded deaths associated with reinfection until 3 months ago.
