The study concludes that "cases attributed to ward-based exposure fell significantly, with FFP3 respirators providing 31-100% protection (and most likely 100%) against infection from patients with Covid-19". bbc.com/news/health-57…
@Nantanreikan So was this alluded to 6/21 pre-print ever published? And if so, did you review the methods & data to ascertain what the actual aRR was? Attached is the abstract from a more recent 4/23 published study in a hospital showing again masks made no real difference.
@Nantanreikan More than 2 years later (just since this article was as written) and IPAC/HICPAC/ID docs still choose disease spread over respirators. It’s UNBELIEVABLE. Fire them all, hire engineers, and let’s end this ongoing raging pandemic! @CDCgov @CDCDirector @CDCGlobal @WHO
@Nantanreikan NO SURPRIZE TO THE HEALTHY that are adopters of Masking and Room Air Filtration. It is not Rocket Science... @CorsIAQ @MeetJess
@Nantanreikan @TRyanGregory Why is this being shared just now when it was published in 2021? More needed to see it in 2021.
@Nantanreikan @covidsafenetwrk Can anyone advice if 3M Aura N95s can be worn in a Brain MRI If staples are replaced appropriately Also nose wire replaced with surgical tape Is there anything in the mask fabric that could be a risk? Aþppointment is almost immediate So no time to order a redimask Thanks
@Nantanreikan @arijitchakrav We've known this for years. Why do the NHS, hospitals & most doctors reject the evidence?
@Nantanreikan This article's got me scratching my head again when it comes to mask standards. I thought FFP3 was equivalent to N95, but this article claims FFP3 is equivalent to N99?
