1/ GOOD VIDEOS TO EXPLAIN COVID-19 AIRBORNE TRANSMISSION

A journalists just asked me for those. So I thought of the ones below, but please reply with others that also do a good job.

2/ A really good explanation of transmission from @marinavance, @ShellyMBoulder et al:

3/ The real reason why social distance reduces transmission.

Aerosols get diluted and rise, so we inhale less of them at a distance, like smoke.

By @VVuorinenAalto

4/ Not to be confused with one of the worst videos of the pandemic, from @WHO, with the incorrect explanation of why social distance works (the large droplet projectiles -- that we now know are unimportant except is someone coughs or sneezes on your face)

5/ A great video showing the importance of mask fit, and how nominally good KN95 / FFP2 masks can leak if not well adjusted

Mask fit is still one of the easiest & most poorly communicated measures

By Prof. Philomena Bluyssen at TU Delft, the Netherlands

6/ A good UK video visualizing exhaled aerosols in everyday situations.

I think @CathNoakes the Great was probably involved...

7/ Not quite a video but an animation of the effect of "layers of protection" on potential superspreading events.

8/ This interview with @weatherchannel felt unusual at the time, but I've been told it was really clear for the general public:

9/ A good demonstration by @kate_cole_ of the difference between droplets and aerosols:

10/ A good animation of ventilation flows by the @nytimes

11/ A great @nytimes animation of the microscopic details of how masks work.

(Hint: contrary to popular belief, a mask is not a colander or a sieve!)

12/ A visualization of exhaled breath using an infrared camera with a CO2 filter, by the @washingtonpost
