It also would be nice to find a well known site that posted the info. I never heard about the 21centurywire before? Are they reputable? Are they crackpots?
Also a source as dry as possible, with a title as dry as possible. Imagine there are 10 hardcore deletionist wikipedia users looking over your shoulder: what title would survive? Something like "Official UK study shows no transmission from asymptomatic covid-19 in open air events"??? The photo in https://news.sky.com/story/covid-19-just-15-people-test-posi... does look like an event inside a building, so my title may be wrong.
Also the recommendation is to use here the original title, so choose the article with the best title. Preferably a dry article that only explain the results and has no conclusions.
Edit: Just to be 200% clear, I didn't flag or upvote this post or the previous post. I prefer to write a rebuttal. If you want to trigger me, post something about the Em-Drive.
