Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

Det börjar ju bli lite tröttsamt att posta detta igen. Men jag blir tvungen. Andningskydd fungerar inte, och det finns hur mycket forskning som helst på det.

Ett exempel:

Lopp & Edwards reviewed the surgical literature in 2014 and found “no statistically significant difference in infection rates between the masked and unmasked group in any of the trials.

Figueiredo et al. in 2001, reported that in five years of doing peritoneal dialysis without masks, rates of peritonitis in their unit were no different than rates in hospitals where masks were worn

Bahli did a systematic literature review in 2009 and found that “no significant difference in the incidence ofpostoperative wound infection was observed between masks groups and groups operated with no masks

Bahli in Sweden, recognizing the lack of evidence supporting the use of masks, ceased requiring them in 2010 for anesthesiologists and other non-scrubbed personnel in the operating room. “Our decision to no longer require routine surgical masks for personnel not scrubbed for surgery is a departure from common practice. But the evidence to support this practice does not exist,” wrote Dr. Eva Sellden.

Spelar ingen roll för nu är det sommar och du är 34 år.
Gnällspik.

Då kan väl du kila ner till covid-iva och säga åt dem att skippa andningsskydden? Som hon här har:

https://www.vardforbundet.se/rad-och-stod/corona-och-covid-19-information-for-dig-i-ditt-arbete/

Du vet att mask, betyder munskydd på svenska?

Varför ska jag kila ner dit? Jag har aldrig sagt att vårdpersonal inte ska ha andningsskydd. Jag påpekade att forskning inte ger stöd för mask som skydd mot infektion. Du hävdar motsatsen, i strid med forskningen.

Mask på engelska betyder mask på svenska.

Andningsskydd är såklart tydligt märkta med olika standarder. Att dom inte skulle fungera mot partiklar av olika storlekar är kvalificerat struntprat.
Möjligen är ffp3 den nivå av skydd man behöver mot SARS CoV-2.

Hur har jag hävdat motsatsen? Andningsskydd ger skydd mot infektion.

När man säger mask, syftar man på surgical masks vilket också står i dina länkar, alltså munskydd. Högre klassning heter respirator (mask).

Det är ju folk i min ålder och yngre som mest är ute och därmed sprider smittan oavsett vi vill eller inte. Okej att de största riskgrupperna ska vaccineras först, men därefter borde det köras på med den som vill och kan direkt.

Någon som förstår varför Delta är så utbredd i just Värmland? Har man gjort något stort industrijobb med mycket utländska arbetare,från Storbritannien nyligen? Några speciella kopplingar till GB på annat sätt Värmland?

Verkar vara ungdomar som sprider det där, tyckte jag läste det. Jag bor inte där så jag vet inte vad som byggs där.

Ja det räcker ju med en som varit till GB och sedan med vaga symtom, lite host och ont i halsen, kanske helt utan symtom är socialt aktiv.

Själv kommer jag att erbjudas en första dos till midsommar och en andra dos 7 v senare när sommaren är slut. Jag kan samtidigt notera att asylsökande över 18 år tydligen går före medelålders svenskar.
Inte förvånande men ett bevis på vad regimen värderar högst.

Det räcker med att en svensk medborgare rest till London och tillbaka. Inget krav på svenskar som reser in i landet. Det är klart att utan screening av alla resenärer så kommer alla varianter hit.
