‘1 in 1,000 cases traced to outdoor transmission’ has now been reported around the world as research from Ireland

To correct record: this isn’t a research study & isn’t valid

Here’s why... 1/ https://www.npr.org/sections/health-shots/2021/04/27/991181424/cdc-if-youre-vaccinated-you-dont-need-to-mask-outdoors-unless-youre-in-a-crowd

basis of ‘1 in 1,000’ is 262 cases in 42 outbreaks
*only from outbreaks where >2 infected, & not all cases
*only from places that ~may~ be outdoors (21 construction, 20 sport & 1 in community)

& this 262 is compared to ~total~ 232,164 cases recorded in Ireland (to 24 Mar 21) 2/

Meanwhile this ~research~ has flown around the world, & risks influencing people’s behaviour & public policy 3/

it’s a fast moving situation & media are under pressure... but we all have ethical responsibilities when speaking publicly in a health emergency 4/
