❗️@WHO updates on main mode of SARS-CoV-2 🦠 transmission❗️

2021.04.30 Q&A ⤵️ ‘How does #COVID19 spread between people?’

I cannot overstate how seismic this paradigm shift is, and should be, in guiding a revised Risk Assessment & Controls framework.

The virus 🦠 SARS-CoV-2 can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak 🗣, sing 🎤, or breathe🧘🏻‍♀️.

[why mask needs to cover👃& 👄]

These particles range from larger respiratory droplets 💧 to smaller #aerosols 💦. Image
The SARS-CoV-2 virus 🦠 spreads *mainly* between people in close (short-range) contact, typically within 1 meter (3 feet) of each other.

When #aerosols or droplets containing the virus 🦠 are INHALED or come into DIRECT CONTACT with the [mucous membranes of] 👀,👃, or 👄. Image
#SARSCoV2 🦠 can also spread in poorly ventilated &/or crowded *indoor* settings from a distance.

❗️because #aerosols carrying the virus 🦠 can remain suspended in #air or travel farther than 1 meter❗️

[why adequate #ventilation is critical]

Yes, importance of distancing from other ⚠️ infectious humans remains.

Scientific understandings on WHY “distancing” can ⬇️ exposure risk to COVID-19 🦠 are being updated.

Farther is better (6ft better than 3ft), but not enough if in an enclosed indoor space for a long time.

An open letter regarding the implications of an early #skpoli election on #COVID19 containment #cdnhealth @PremierScottMoe @ryanmeili @zakvescera @mmandryk
As a public health physician based in Saskatchewan, I am greatly concerned by the Premier’s remarks about calling a snap spring election in the face of the expanding worldwide outbreaks of COVID-19 (Coronavirus).

Canada and the rest of the world only learned of this brand-new virus just over 8 weeks ago, but already there are more than 110,000 confirmed cases and 3,825 deaths reported worldwide as of Sunday evening.
