I think it’s time to revisit masking with #BA2 & how contagious it is. I am upgrading my recommendations to a P100 @3M respirator. They are less likely to suffer structural damage, meaning I have had them in use for 1 year at a time. That 100 is for 100% an N95 is 95% blocking ImageImage
Note do NOT use @amazon they have a huge issue with #CounterfeitMasks. The @US_FDA doesn’t seem to be doing their job & cracking down while Bezos lounges on his yacht. I have samples of counterfeit 3M masks I bought off of Amazon. I confirmed with 3M DIRECTLY. So this is serious
This isn’t hearsay but actually provable. Amazon hides behind “tHeY aRE iDepEnDanT coTrAcTOrS” while they rake in that sweet pandemic cash. I recommend you order from @HomeDepot as they buy directly from 3M. I wish I had a better solution. #MaskUp #P100Masks #CovidIsNotOver
Note my “Care & Feeding of N95 Masks” still applies. Buy spare filters to allow them to dry between use. I recommend 3-5 days in a dry room out of direct sun (UV damages the filter). #BeSafe #COVID19 #BA2variant @CDCgov you paying attention? History will remember your (in)action Image
@DrEricDing you may want to warn people of the counterfeit masking issue. It’s disgusting!

I want to share an analogy & call to #Hospitals to #ProtectHCWs. 2+ years yet hospitals leave workers open to PREVENTABLE death & disability. They need to held to task & REQUIRED to properly & fully protect their workers. Please join me & share this. #HCWs #Covid #LongCovid (1/3) ImageImageImageImage
#HCWs DESERVE government protections, as do patients! It is unethical for them to continue to skirt proper air filtration & personal protective equipment MINIMUMS. @OSHA_DOL are you listening? #OSHA #P100 #respirators #Ventilate #HEPA #LongCovid #CovidIsNotOver #MaskUp (2/3) ImageImageImageImage
Providing P100 respirators, increasing proper indoor air filtration, & testing workers regularly will help attract & retain staff. In addition to it being the RIGHT THING TO DO! Questions? Contact me #DoTheRightThing #LegislateProtection #ProtectHCWs #Nurses #ProtectRNs (3/3) ImageImageImage

Let me tell you a story. By Jan 7, 2020 I knew this was airborne based on the spread occurring in China. By the 21st I had calculated an Ro of 2.4 (turned out to be pretty damned accurate). By the 23rd I called on my fellow healthcare professionals to ensure they had N95s
Or better yet P100 respirators. Then the backlash started. On the 27th I was openly mocked online by an ID doc I had worked with. It snowballed. I was trying to get anyone to listen. I was treated like I was nuts. All I was advising was to stock up on PPE & be prepared
I advised that we figure out a system for increasing mask longevity/reuse at my hospital system. I was dismissed as “reactionary”. The ICU attending & ID MDs went on international vacations in February & March. The hospital admin ignored this. I started posting videos on PPE

I have been asked a number of great questions! So let’s go through each point of my “Care & Feeding of an #N95 #Mask”. Bending or crumbling breaks apart the polypropylene fiber bonds, the magic fiber that filters out & traps the virus using electrostatic charge. @DrEricDing 1/12 Image
Electrostatic charge is like a magnet for the virus. #N95 masks do not rely on layers to filter. 90% of their viral filtering ability is due to this electrostatic charge! If you damage this charge the masks become about as effective as a cloth mask. 2/12 nature.com/articles/d4158…
Washing these masks is destroying them. The agitation breaks apart the polypropylene bonds, opening up the filter, it also permanently destroys the ability for the polypropylene to maintain the electrostatic charge. If they are soiled, please dispose. 3/12
