Dose makes the risk - more the inhaled dose, more the risk of infection. These are screenshots of a slide deck made with pointers from @CorsIAQ and @ayushumd
A 🧵 1/

2) Risk of infection can be related to the inhaled dose. This helps to understand mitigation measures at a very simple and basic level. The slides were intended for high school students

3) Start with a dessert - in this case, an Indian dessert. If you are a bigger sweet tooth than me, you must want lots of spoons of sugar, right?

4) Similarly, but in a more scary way, if you inhaled more virus bearing particles, you would be at greater risk. And how much you inhale depends on the factors below

5) If you are trying to explain it very simply or think about it critically, think of factors that affect your breathing

6) What affects the amount of virus bearing particles in the surrounding air?

7) Time spent has to be an important factor right?

8) And finally, all this thinking so that we can mitigate it right

9) Three simple heads to arrange your measures under - distancing, less time spent, avoiding crowded spaces, masks, ventilation - all of them can be put under one or more of these heads. Try for yourself.

10) Think a bit more about the virus bearing particles floating around you - now, in terms of mitigating

11) Can time help us?

12) What is the problem with crowded spaces?

13) Exercise, outdoors, and ventilation (dilution).
Outdoors can help out a lot. Think and plan carefully.
In the same vein, do not just convert outdoors into an extension of indoors using enclosures or with overcrowding.

14) Tiny drops can gather to make an ocean, then they can certainly gather to reach an infectious dose.

15) Our goal is to minimize how much of these virus bearing particles get in.
