(1/17) @rivm in Nederland besluit uit haar literatuuronderzoek, na 2,5 jr pandemie, dat niet bewezen is dat mobiele #luchtreinigers transmissie v #COVID19 helpen reduceren. Die stelling is onzinnig, onverantwoord, zelfs schadelijk. Vraagt om 'en draadje.

(2/17) Uiteraard moet het gaan om goede apparaten die voldoende krachtig zijn voor de ruimte waarin ze opgesteld staan (reinigingsfrequentie van minstens 6 keer per uur) en moeten ze goed onderhouden worden. Evident. Geldt voor alle mechanische systemen.

(3/17) Een draadje met drie argumenten, en daarna een aantal opmerkingen.

@NjbBari3

Monkeypox is not transmitting as fast as smallpox because it’s not adapted well yet. In virus terms it’s just getting to know us. Smallpox took many, many years to become what it was.

But that doesn’t mean it is using a completely different tactics to transmit. #Aerosol

MPx is known to transmit in many ways… including aerosol in animal studies.

If I’m wrong, you wear a respirator for a couple of years and save yourself some COVID infections.

If I’m right, and we don’t act on this, it’s going to get grim.

PS. MPx has been classified as an airborne HCID since it was discovered. I’m not talking whacky science. I’m talking ordinary boring science.

Wie sicher bin ich mit #Maske, wenn andere nach den anstehenden #Corona-Lockerungen keine mehr tragen? Ein Thread 1/9

Das Problem für alle, die sich schützen wollen: Masken sind nicht nur #Selbstschutz. Infizierte mit Maske verbreiten weniger Viren.
Das galt schon vor #Omikron (englisch): 2/9

Gegen Omikron schützen Masken sogar wohl noch besser als gegen frühere Corona-Varianten: 3/9

1/7 Relato sobre cómo se está manejando #Pandemia en estab educaciones #Escuela . Es norma definida x autoridad?, la respuesta es simple: SI. La norma es absurda? también. La norma tiene como principal fin la protección de NNA?: en mi opinión, NO. Esto recibimos esta mañana 👇

2/7 Ayer entre alumnos ya se hablaba de un caso positivo, pero norma no obligaba a reporte inmediato del establecimiento. Esta mañana informan dos. Pasaron un par de horas y llega una segunda comunicación, ya son tres y se suspenden clases por una semana. #Pandemia #Escuela

3/7 cuál es sentido de no comunicar inmediata%? Q respaldo tiene establecer q ante 2 casos corresponde cuarentena para quienes se “sienten” a menos de 1m ?Recordemos q al ser principal forma de contagio #Aerosol en espacio cerrado se relativiza mucho distancia #Pandemia #Escuela

I got home this morning after an overnight shift in the pediatric emergency department.

I rarely share personal reflections based on my clinical work as a #pediatrician via @twitter, but I'm allowing myself this exception.

#omicron #COVID19Qc #N95sForAll

A thread 🧵 1/21...

2/ I started my winter holiday stretch of shifts by working on #Christmas evening and finished it by ringing in the #NewYear last night while taking care of sick & injured children with a phenomenal (but overworked & somewhat demoralized team) at the children's hospital.

3/ Let me re-iterate at the outset that I've always been opposed to @francoislegault @coalitionavenir's imposition of the #curfew because of its harmful impacts on many of the most marginalized people in society.

1/ #SARSCoV2 leviää #Aerosol viruspartikkelien avulla joita uloshengittää tartunnansaanut. Haluat välttää näiden partikkeleiden sisäänhengitystä (🦠partikkelimäärä⬇️). #Vuosikymmenien_tutkimus kertoo seuraavien keinojen laskevan sisäänhengittämiesi aerosolpartikkeleiden määrää:

https://twitter.com/CorsIAQ/status/1426261035887915009

2/ #Maskit: mitä korkeampi laatu ja mitä parempi istuvuus kasvoilla, sitä vähemmän sisäänhengität itse aerosolpartikkeleita joita tartunnansaanut uloshengittää yhteiseen hengitysilmaanne. Tämä ei ole rakettitiedettä.

Aerosol voi ilmaleijailla tunteja.

pnas.org/content/118/4/…

3/ #Ilmastointi: Mitä tehokkaampi ilmastointi ja #Tuuletus, sitä vähemmän ilmassa on aerosolpartikkeleita joita tartunnansaanut/-neet hengittävät yhteiseen, jaettuun sisäilmaanne. Näin sisäänhengität viruspartikkeleita itse vähemmän. Tämä ei ole rakettitiedettä, vaan simppeliä.

@elivito @ANirospe @AurelianoStingi @LongCovidItalia @LongCovidKids compreso il cervello, con danni a lungo termine ancora ovviamente non chiari, ma con potenziali scenari che destano molta preoccupazione (cfr @stefaniaconti). Già questo è motivo più che sufficiente per vaccinarsi!

@elivito @ANirospe @AurelianoStingi @LongCovidItalia @LongCovidKids @stefaniaconti Però credo che il problema che qui si vuole evidenziare è un altro, e riguarda la comunicazione veicolata dai media mainstream durante la pandemia.
A me pare che essa rientri appieno nella categoria della "propaganda" più che dell'informazione

I'm excited to share with you our recent @biorxivpreprint where we demonstrate that @vaxart mucosal Ad5 #SARSCoV2 vaccines not only protected against disease but also reduced transmission after post-#vaccination #SARSCoV2 infection in a hamster model. biorxiv.org/content/10.110… A🧵/

If you follow me, you are well aware of my obsession w/ #mucosalimmunity.😂Protection generated at mucosal surfaces is at the crux of one of the biggest questions we need to answer during this unique phase of the #pandemic - How do we decrease #SARSCoV2 #transmission to others.

Considering most of the world is unimmunized (including most kids <12), the possibility that a vaccinated individual with a post-vaccination infection (aka #breakthrough) can spread #SARSCoV2 is a public health risk. We need #transmissionblocking strategies.

@prof_nch (1/?) Profs thinking it’s ok to exercise privilege & unmask to teach in indoor classroom of students who must attend or possibly fail class—either have COMPLETELY NO understanding that 1)#aerosol is main transmission route for #COVID19; 2) how aerosol transmission actually works;

@prof_nch (2/?) 3) #Delta is hypertransmissible with rate of 1 infecting on avg 5-7 more vs earlier strains 2-3 more; 4) most infected don’t know they’re infected when they are at their most infectious because symptoms only show after peak infectiousness—if ppl not asymptomatic; …

@prof_nch (3/?) most have no real functional understanding of indoor air quality in own classrooms & rely solely on air system filtration—don’t monitor it with CO2 meters, keep windows/doors open; 4) don’t think about minimal acceptable air quality vs ‘good/excellent’ by #ASHRAE standard;

This interview with @mtosterholm is 🔥. One of the clearest & most succinctly accurate 6-min summaries of where we are with Delta/COVID mitigation, masks, & vax (best part starts at 1:30).

#VaxUp #BetterMasks #N95 #MasksInSchools
A few quotes below. h/t @PPEtoheros, @citlanx

https://twitter.com/CNNnewsroom/status/1425474417350615041

"This virus is an #aerosol. It’s transmitted in the air, just like we see with cigarette smoke. If you’re in a room and you have a covering on your face and you can smell* the smoke, then you know you’re also getting virus in there if in fact you had an infected person in there."

* (Editorial comment on the smoke smell comment. Aerosols in smoke come out as a concentrated plume, waft through the air, & build-up indoors. But the smell is from the gases & can go through masks, whereas aerosols are blocked. Good visual analogy, but it breaks down at smell).

1/ Our paper is now published in final peer-reviewed form in CID! In this study, we recruited 22 #COVID19 patients at NCID and collected breath samples using a G-II machine while they were talking, breathing, and singing.
@IDSAInfo @drkristenkc @Don_Milton
doi.org/10.1093/cid/ci…

2/ 13 (59%) of patients had detectable #SARSCoV2 RNA by PCR in exhaled breath samples, with 85% comprising fine aerosols <5um. There was significant variation between patients, with 2 patients accounting for 52% of the total viral load - may explain so-called "super-emitters".

3/ Detectable RNA in aerosol was associated with earlier day of illness: median 3d (IQR 2-5) for those with detectable RNA vs 5d (4-7) for those without. It is clear that patients are most infectious at illness onset, emphasising need for early case detection and isolation.

Logik: Die indische Mutante #Delta (#B16172) breitet sich massiv in #England aus und da sollte man erwarten, dass das #RKI sofort die unzureichende #Einreisequarantäne verbessert - aber nein - das RKI stuft die #COVID-Gefahrenlage für Deutschland herunter

#BC ought to be grateful for work of @PennyDaflos asking hard questions & keeping officials accountable to truth & science during #COVID19 👉👉bc.ctvnews.ca/international-…

#DrBHenry gaslit #BC that she would ‘follow the science’: “Responses from British Columbia officials are part of a damning analysis on the reluctance by public health to acknowledge the airborne transmission of #COVID19 despite scientific consensus on the matter.”

#DrBHenry @adriandix & #BC #PHO ongoing refusal to recognize the primary transmission route of #COVID19 by #aerosol mechanism surely hobbled #BC response—to what extent & cost —ultimately in lives lost, #longCOVID, trauma, suicides, etc. have yet to be determined
