Repeating warnings from @H_S_E and @NIOSH about earloops having a low fit test pass rate is unpopular, but what does the published literature say about earloop KN95s? #KN95
One study found that “KN95 masks failed fit testing in all (82 out of 82, 100%) healthcare workers evaluated”. openres.ersjournals.com/content/6/4/00…
Another study of #KF95 mаsks found that: “A result of ‘failed’ was recorded for 39 of 42 fit test episodes”. ijic.info/article/downlo…

*A thread on why the trouble in #China is real*
#Singapore is one of the best test cases to judge the sentiments in #China. Now I gather that many Mainland Chinese families living in 🇸🇬are shipping essential medicines to their loved ones in 🇨🇳owing to a lack of stocks.

Reports show that anxious relatives in #Singapore are waiting for hours together in long queues to procure medicines and then courier them to addresses in #China.

Seeing this, Singapore's Ministry of Health has advised the public to buy medicines for their own use only.
The major drugs being shipped from SG to 🇨🇳 include the painkiller Panadol & the traditional Chinese medicine #LianhuaQingwen.

This is what concerns me. Bear with me in this thread. Prior to #omicron sub variants, I could reassure patients & tell them they probably had a few months of protection. Not anymore. Cause if you had omicron, you are not likely protected against the newer BA.4 & BA.5 strains.
Hence your risk of infection & then reinfection is now very high. Why? Cause these #variants are escaping the #vaccines.
So for those living their lives & not trying to avoid the virus, your risk of #longcovid is very high.

I am especially pleading to the young population, the last thing you want is suffer from #brainfog & #shortnessofbreath for the rest of your lives. We don’t have a cure at this point for #longhaulers. Your goal should be to AVOID this virus but if not, avoid getting reinfected!
🧵 If the use of airborne #PPE & improving air quality in healthcare settings are to be ‘optional’ & ‘a matter of personal choice’, then we should give strong consideration to applying the same rule to the following #MedTwitter #MedEd #TeamGP 1/n
1. Handwashing before, between & after patients (& audits of it)
2. Plastic gloves & aprons
3. ‘Bare below the elbows’

1/🧵 Somebody had to die to get me a bed…
Voice on to listen: 🎧
My patient, now a #LongCOVID survivor & mentor to young Black boys told me…
“I was getting so sick w #COVID, & there was not a bed. They called everywhere & suddenly that night they said the VA got a bed.

2/ So somebody had to die that day, you know, so I’m just saying, wow, you know. But I told my wife, when I left here, I’m in God’s hands, you know, and I don’t know why I said it, but there was nothing she could do for me. (Pics w perm)
3/ So many things fell into place, it’s just not a coincidence. I thank God every day. I’m a different kind of guy, you know. I had to change a lot of my life. I got involved w young men to try to change the trajectory of their lives. That changed me & became therapy for me.
CDC came out with another incremental update on #mask & #respirator guidance today: cdc.gov/coronavirus/20…
Clarifies N95s aren't in short supply & can be worn again!
It's still not perfect, but it feels like we're at least inching in the right direction. Some thoughts via a🧵.

2/ New statement that most respirators (i.e. #N95s) "are disposable and should be discarded WHEN they are dirty, damaged, or difficult to breathe through."
So you CAN #ReuseN95s‼️
See, e.g.:
That's *much* better guidance than to toss after a single use!

See, e.g.:

3/ Also clearly states that:
"Loosely woven cloth products provide the least protection ... and well-fitting NIOSH-approved respirators (including #N95s) offer the highest level of protection."
YES!!

BREAKING—@CDCgov is now considering updating its mask guidance to recommend that people opt for #N95 or #KN95 masks worn by health-care personnel, if they can do so “consistently” (e.g. feel comfortable wearing all day)—c’mon, @CDCDirector—go all the way!
washingtonpost.com/health/2022/01…
washingtonpost.com/health/2022/01…
2) “The updated guidance is expected to say that the best mask is the one that is worn consistently and correctly. The CDC guidance is expected to say that if people can “tolerate wearing a KN95 or N95 mask all day, you should.”
3) “CDC Director Rochelle Walensky has previously declined to officially endorse Americans wearing N95s regularly, rather than a typical fabric mask.”

A 🧵 to counter some confusing messages about masks & wildfire smoke (1/x)
1. High-quality masks (i.e. #N95) best for both viral aerosol + #wildfire smoke
2. N95s readily available & should be used for both
3. But other masks can provide non-zero benefit

denverpost.com/2021/08/10/wil…
2/ The #CDC and #EPA both strongly recommend upgraded masks (respirators) like #N95 or #KN95 to protect against wildfire smoke. I totally agree (unless using something even better like N99 or elastomeric), b/c these filter the smallest particles very well.
cdc.gov/disasters/covi…
cdc.gov/disasters/covi…
3/ But the #CDC also says not to use N95s, b/c they "should be reserved for health care workers." I totally disagree, as do countless others, b/c supply chain problems in 2020 have recovered in the US.

#GetVaccinated vs. #COVID. Vaccines stave off hospitalization, death and even worse for some people, sexual performance. Let's discuss some of the math, pros and cons, and adverse effects and that sexual performance thing. THREAD: texastribune.org/2021/07/21/cor…
2/ Most who are dying or are being hospitalized are unvaccinated. The vaccines don't give 100% immunity, but they are free, easy, painless and provide good protection. They also greatly decrease the impact of COVID if you do get it.

3/ COVID vaccines don't magnetize you and are too small to insert a tracker. Regardless, the government can already track you through your phone, computer, email, credit cards, social media, etc., etc., etc. Fully vaccinated folks are now <1% of deaths. cnet.com/health/99-of-c…

2/ "NIOSH has been informed that many legitimate manufacturers in China have been counterfeited. In such cases, NIOSH has no way of verifying which products are counterfeit and which are authentic.
3/ "While the manufacturer listed in the table is shown as the manufacturer of the product evaluated, NIOSH has been informed that some of these are actually counterfeit products.
1/ On February 2, 2021 the National Personal Protective Technology Laboratory (NPPTL) published assessments for many foreign made masks, including KN95s. Some minimum #KN95 filtration results were < 26%! But others had >95%. @AbraarKaran @linseymarr @zeynep @CorsIAQ
2/ Before we get to the results at tweet 7, you should read the introduction. Excerpts: @nataliexdean
"[T]en respirators were submitted for evaluation. The samples were tested using a modified version of NIOSH Standard Test Procedure...
