Dear #Saskatchewan,
Time is of the essence in containing #COVID19SK, esp. when our epidemic “curve” is no longer flat. The Effective Reproductive Number “R(t)” is now 2.2
Pls add measures to control #aerosols transmission & #Mask4All indoors in areas w/ active transmissions. https://twitter.com/SaskHealth/status/1288908976516562945

A major paradigm-shift is required by Public Health/IDs/IP&C at this time to implement effective containment measures to slow the exponential spread of #COVID19SK.
ie. recognition of short-range “airborne” spread by “aerosols” & the relevant roles of face mask
+ ventilations.

For an UTD review on current scientific understandings, see @zeynep’s excellent summary @TheAtlantic today 
change req’d:
Recognition that the paradigm of “droplet vs. aerosol” route for resp. pathogen transmission is an outdated, false dichotomy. https://www.theatlantic.com/health/archive/2020/07/why-arent-we-talking-more-about-airborne-transmission/614737/

Though targeting IP&C in healthcare settings, the new lit review article by Dr. Kevin Fennelly for @LancetRespirMed is equally important.
Dr. Fennelly speaks directly to a medical audience as a physician who has studied tuberculosis for over 20yrs.

Impt to note:
#PhysicalDistancing is still an effective measure to reduce exposures to SARS-CoV-2 virus
But on its own, staying > 2m/6ft apart in High Risk settings (Close contact, Crowds, Closed space) is not adequate to stop COVID-19.

Medscape article by Prof. @jljcolorado
Assumptions underlying the FALSE dichotomy of “droplet vs. aerosol” paradigm led to the FALSE belief that #SARSCoV2 cannot be found encapsulated in #aerosols or “droplets” that are “airborne” for min to hours.

My attempt at summarizing the science re: RISK of over-reliance on #PhysicalDistancing (assumption: #SARSCoV2 not transmitted by #aerosols that can be inhaled at distance > 1-2m away from source) while ignoring roles of & ventilation.
Thx @sammaciag!

I missed the updates from yesterday. Thx to @CPraillGlobal & @MickeyDjuric for flagging this.
R(t) value of #COVID19SK is
:
R(t) = 2.2
