People in their 20s are now disproportionately represented in new COVID-19 cases in Ontario.

Instead of shaming & blaming, I asked them what challenges they’re currently facing with respect to the pandemic.

After 100s of replies, some key themes emerged. Here they are:

Many people in their 20s mentioned peer and social pressure, plus general difficulty navigating behaviours of those around them as a major challenge during the pandemic.

Difficulty seeing or isolating from family was cited as a key challenge folks in their 20s are facing.

This one is big given data from France suggesting cases in young people eventually spread to older folks in 3-5 weeks.

A quick visual guide to risk assessment, based off some of the fantastic research summaries created by @mugecevik @firefoxx66 and @ErinBromage

1/13

Your exposure risk is some function of viral dose & time.

The tricky thing is we don’t know how many virus particles it takes to cause an infection, and this will likely vary from person to person.

The good news is we know some ways to reduce our relative risks

2/13

Time is perhaps an under-appreciated component of the risk equation.

Slow & steady can “win the race” to an infection too.

PSA TO MEDIA:

“AEROSOLS” is jargon - IT IS YOUR JOB TO CLEARLY STATE HOW THEY DIFFER FROM DROPLETS WHEN SHARING RESULTS FROM THE NEJM PAPER.

In a nutshell: COVID-19 patients likely cough/sneeze DROPLETS, which are larger than aerosols and all fall to the floor within 1-2m, give or take.

AEROSOLS are smaller so can last in air for longer, but are very likely only produced in hospitals after certain medical procedures

THE TAKEAWAY: this paper does NOT mean SARS-CoV2 is floating around in the air for 3 hrs - it does NOT seem to be airborne like that (the R value would be much higher if it were).

Healthcare workers DO have to deal with aerosols so save the masks for them.

YES, hand sanitizer DOES kill many viruses, not just bacteria. Here's how.

#FactsNotFear #COVID19

To clarify the line about water (I struggled to multi-task😅): a mixture of water & alcohol is better than 100% alcohol for many reasons - the water keeps hands from drying out too much, helps with penetration, and even slows down evaporation of the alcohol so it has time to work

But it’s the mixture of alcohol in your hand sanitizer that helps to dissolve away the molecules that make up the cell membrane of bacteria or outer coat of a virus.
