I think we'd best have a conversation about mask efficacy in the context of time-to-infection, viral load and other highly-speculative estimations that have been proffered over the course of the pandemic thus far.

You cannot build a rock-solid scientific model on top of such things.

Can someone share the best mask recommendations for COVID currently? There are some pictures with in-depth test results and comparisons - can people reshare those pictures? (Trying to find them, struggling)

Pels q fem servir #mascaretes, i coneixem la seva utilitat i eficàcia vs #SARSCoV2 i altres virus, una gran lectura, a:

Tota aquesta entrevista és aprofitable. Què bo hagués estat q les coses s'haguessin explicat com tocava, quan tocava. Parla de temes obvis, com la necessitat q els #mascaretes ajustin bé (#FitTest), que l'efecte combinat és sempre millor q l'unidireccional, que tenen una eficàcia limitada (com tot a la vida)... Deixo un extractat gairebé perfecte...

#DeepThoughtsFromIPC So, ask your staff if they can't taste/smell before you do a qualititive #FitTest of an #N95 or #respirator. If they can't taste, fit test won't work very well! In theory, sensitivity test would fail them. #COVIDIsNotOver

Les #professionnels de #santé (notamment en #libéral) qui portent des #FFP2/#FFP3 bénéficient-ils d'un essai d'ajustement (sans lequel l'efficacité du #masque n'est pas garantie) ? https://en.wikipedia.org/wiki/Respirator_fit_test #FauxSentimentDeSécurité #FitTest
