      So when well-meaning medical workers explain their own mask donning/doffing procedures to you, the regular person wearing maybe a cloth-mask (good for you!) or even a surgical mask or that N95 you had leftover and you're sanitizing/re-using, they are aiming at the wrong target

      What should you do? Well, follow the advice to the best of your ability but realize that you're not in a biosafety lab. First, masks don't replace distance. They add to it. Second, pay most attention to taking them off correctly and immediately washing your hands. Most important.

      While shopping with distance, if you accidentally touch the outside of your mask, should you rush to take it off under biosafety level 3 rules? No. Mask still protects *others* from your potential spread. Yeah your hand can carry some virus there but remember viral load matters!

      So medical folks aren't wrong but not targeting correctly. Stay away from others when you go out for essential activity, replace especially cloth masks often (few hours max), be careful especially taking them off, handle them carefully and wash hands immediately. That's it.

      Also, I have been wearing transparent gloves out since February (my students can laugh about me explaining them in class!) and I sanitize over them all the time. Basically, I am still trying to be careful and treat them like my hands, but they can handle a lot of hand-sanitizer.

      Yesterday, I learned that maybe even half of shoppers in regular grocery stores were wearing masks here in Chapel Hill. I last went out a week ago, and it wasn't even 10%! I am thrilled that it's taking off so quickly. Hope everywhere else, too! Meanwhile, stay home if you can!

      Btw I've seen ZERO evidence that incorrect mask wearing *increases* risks to regular people compared to NO MASKS. The One study that the faux experts go on and on about looked at cloth masks compared TO surgical masks IN hospitals. Uh, duh. Surgical mask > cloth mask for a nurse.

      Like this piece in @washingtonpost. It's full of weird speculation, too little actual science plus wrong conclusions. We've had some amazing journalism and also terrible performance by some health/science reporters who seem utterly unqualified.https://twitter.com/Pinboard/status/1247033976239218688 …

      The Washington Post continues to give the most backhanded advice about mask wearing in public, a lifesaving, proven public health intervention that we need to adopt immediately. There is NO evidence masks can make you sicker. This is shameful. https://www.washingtonpost.com/health/2020/03/13/if-you-feel-sick-are-worried-about-coronavirus-call-your-doctor-dont-rush-er/ … pic.twitter.com/4l92F5Yq5f

      What would you think about a safety "expert" who said, without any evidence, that helmet/seat-belts make bikes/car less safe because of overconfidence and thus maybe don't use helmet/seat-belt? That's how wrong those faux experts are. Disqualifying error.https://twitter.com/DaveM604/status/1247177638944182275 …

      But how do you measure false confidence in mask effectiveness, particularly in protecting the wearer? It seems all too likely some will think, "hey I've got a mask, therefore I can get groceries more often, sidewalk-swerve less, wash hands less etc."

      By the way, one key example on importance of masks is Japan. It's not testing, it's not socially-isolating, it's dense with public transportation. But people wear masks. It *will* have an outbreak but with *only* masks slowing things down, they haven't yet become NYC or Lombardy.

      Yes! "We found virus bits in a PCR machine" is not the same as viable virus that can infect you—let alone a high viral load. In general, stainless steel-type high-touch surfaces are most dangerous, porous (cardboard, paper) is least. Wipe, don't panic.https://twitter.com/Charliewking/status/1247180858366349312 …

      Also can we get on the constant talk about lifespans on various surfaces not pointing out that these are based on lab trials and not like... your steering wheel, and that there have been very few (I’ve heard none) cases of transmission via surfaces? Bad info causes panic/harm.

          Folks, see for correct terminology. Sorry. The meaning of tweets are correct, but apologies for typing too fast. (People with a higher viral load are likely spewing out higher viral doses—so you get the point. But also stage/load/dose stuff isn't linear.)https://twitter.com/ghoshuvo/status/1247207401847238658 …

          ‘Viral dose’ or inoculation amount is what you mean I believe. One’s viral load is how much virus your body carries after the virus replicates in you (at any given moment), after it has a chance to begin an infectious process.

          Yes, this is *exactly* why many well-meaning medical workers are not good at giving people advice on how to wear your mask or glove as an ordinary person who is not in a lab or a hospital or doing intubations etc. They're trained for something else.https://twitter.com/PersistentSeekr/status/1247245432868057088 …

          Yeah I saw a scientist talking about her glove procedures in the lab and using that to say no one should bother with gloves because you touch your credit card. Like, dude, I realize I can’t be sterile; I’m just trying to shift the probability distribution to the left

          Also I'm tired of people who won't wear a mask but smear copious amounts of sanitizer on their grocery packaging as soon as they bring it home. Ingesting sanitizer is not good for you, either.

          Actually no - your first false step in the thread. Live #COVID19 virus does survive for days on many surfaces🖼. The answer is to always wash hands after touching any public surfaces before touching your mucus membranes or any "clean" surfaces.pic.twitter.com/LEKjFnrMTz
