Nope,it hasn’t. If your glasses are fogging up in sync with your respiration rate or within a very short timeframe your mask is not sealing. Period. The only difference is when you have either have a valve mask, work with a face shield or similar things or in confined spaces - it’s basically impossible to fog up your glasses with a correctly positioned mask as the filter medium does work as a diffuser. If your mask does fog up suddenly despite a confirmed fit it usually is a warning sign for a breakdown of the filter medium.

(And believe me, we tried really hard - as part of a customer contract we tested all major mask manufacturers available in the EU, with a sample size in the 4 digit range, including UV fluid and thermal imaging tests)

I am fully aware that the equivalent of N95 is often seen as comparable to FFP2, but this is not actually quite correct. The FFP2 has a slightly worse filtration rate and a slightly higher resistance both for inspiration and expiration. Anyway, I intentionally wrote FFP3 as this is the recommended FFP class for Measles while within the NIOSH legislation only a N95 is recommended.

Mostly yes,but it is possible to have some beardstyles if you know very much what you are doing (and have a large head).

But the actual area of contact and to a certain degrees the areas around it need to be shaved properly,yes.

Every vaccination has a (although very slim) chance to cause an adverse reaction. Around 5% of all people vaccinated have a minor skin reaction (which is physiological and not an anaphylaxis. 1% report joint pain.

But,more severely, 1-4 people out of a million develop a life-threatening anaphylaxis, 3 out 100.000 a serious blood clothing disorder. Very rarely(as in: Less than 1 in 1 Million), but with a slightly higher incidence of you are an adult pancreatitis and deafness is reported.

As medicine is always a game of chances we try not to risk things,even if they are rare.

Healthcare professional here - but not your HPC and you cannot confirm that I am who I am so double check what I write:

• Get your titers checked and get revaccinationes asap. If you are not vaccinated or are a non-responder talk to your healthcare provider. Isolate until then.

• Mask up and keep your hands away from mouth, eyes and nose. You will need a properly fitting FFP3/NP95 mask here - measles are far meaner in terms of infectiousness than COVID. Tight fitting means: You have no leaks at the side - if your glasses fog up, if you can feel air going in or out next to your face,etc. it is not working. The usual “duckbill” masks with straps around the ears very very rarely fit properly.

• Wash your hands and desinfect them properly.

• Stay the fuck away from babies. Really. Please.
