Great website, I just have one suggestion. Before the message to wear a mask have in big red letters: "DO NOT GO OUT IN PUBLIC UNLESS IT IS ABSOLUTELY NECESSARY! No mask is more effective than simply not being around other people. BUT, if you absolutely must go out..."

Most of us on HN are well off and have the opportunity to WFH. Things aren't the same for the rest of the general public. All of those essential workers risking their necks for us should have access to masks.

To echo this, wearing a surgical mask consistently will maybe decrease your odds of getting Covid-19 by a factor of 3. That isn't the same as being immune so don't take unnecessary risks.

No, it's a reduction by a factor of 1000 or more. Doctors use them around infected patients and doctors aren't dropping dead like flies.

With Covid-19 they are. One in Italy; 9 in the Phillippines; two in America; several in China. This is not normal.

While I agree, it wasn’t just general public opinion. In NYC at least, it was widely stated in the media by government officials and doctors that masks were unnecessary if you’re healthy, and actually could be bad because people were 1) removing surgical/n95 masks from supply, 2) wearing a cloth mask improperly sanitized can make you sick with other things. I like how Jeremy’s site has directly addressed those origin…

does it have to be n95 to prevent spread? my understanding was the n95 rating protects you from infected people where a plain old surgical mask protects others from you. In other words, the n95 mask has what it needs to prevent you inhaling the virus where a regular mask has what it needs to prevent a sneeze or cough from escaping to the people around you.

Your understanding is incomplete. Both filter virus particles with different degrees of effectiveness. Viruses are typically most present in aerosolized droplets which are much much bigger than the gap size of a surgical or n95 mask.

So, here's some information I've been seeing about masks. 1. After breathing in a mask for a while, the outside is now "potentially contaminated" with COVID19. Treat the outside of a mask as if it were infected. Do NOT touch the mask while using it. Do NOT rub your eyes, etc. etc. Do NOT put on the mask backwards. It is recommended to color-code the inside and outside to make it easier to see. 2. There are a ton of d…

"Note that "N95" masks are only 95% effective against viruses (even if you did everything correctly)."

There are masks that offer greater protection than N95. Among them are N99, N100, and various others. There's a good article that discusses some of the differences here: [1]

"N95 masks are disposable. One-time use"

Some types of N95 masks are disposable, others are reusable. Also, even the disposable kind could be (and have been) reused. This is, for example, widely done in hospitals where there's a short supply of masks, on the theory that some protection (even if imperfect) is better than no protection.

> I wonder if this will lead to people in the west wearing surgical masks during flu season like people do in Asia. Normalizing masks will also help fight facial recognition. IIRC, the Chinese systems have trouble with people who are wearing a surgical mask and sunglasses. No attention-grabbing dazzle makeup required.

Until the government bans masks in public places in the interest of, you know "public safety" once the covid-19 crisis blows over. It sucks that we even need to think about wearing masks to escape facial recognition.

The only effective resistance is being in control of information dissemination to the masses.

Otherwise you will be marginalized and the masses will be "educated" by the mass media about how evil and troublesome "you people are."

Ensuring diversity in information dissemination is absolutely key to shooting down these proposals which harm personal freedom.

Those cases cannot be conclusively linked to a failure of the masks to filter. Ergo, I'm not wrong yet.

False - hand to nose mouth contact is THE primary vector for this illness - masks are very effective in reducing this. Please stop spreading misinformation as it could lead to deaths.

> hand to nose mouth contact is THE primary vector for this illness Do you have a source for this? It's contrary to most of what I've read (droplets through air is primary vector).

Droplets through the air is not primary vector - this is not aerosolized well like measels, the drops fall to the ground -> 6 foot rule is designed to avoid most droplets.

"In an adjusted analysis of compliant subjects, masks as a group had protective efficacy in excess of 80% against clinical influenza-like illness." -https://www.ijidonline.com/article/S1201-9712(08)01008-4/ful...

All the folks saying masks don't work literally never cite to any actual study - I think it's something like 90+ studies showing masks work and maybe 1 or 2 without a good result for masks.

Per Chris Martenson[1], three reasons for every person to wear a mask: - Stops infected people [including asymptomatic] from expelling infectious particles. - Helps remind you not to touch your face [and precludes direct touch to mouth and nose--where mucus membranes are vulnerable]. - Much better chance of a low inoculum [a smaller initial viral load results in less severe symptoms]. [1] https://youtu.be/i6Gy9nPAQE0…

> Helps remind you not to touch your face Hmm, I'm not sure about this one. Going to the pharmacy today, I noticed some people wearing masks, and just in the short time I saw them, many were adjusting/fiddling with their masks.

There is a definitely a learning period when you wear a new type of garment eg. suits or turtle necks, when you adjust a lot. Then you learn over time, and stop adjusting so much.

If you are concerned you will infect yourself by touching your face too much, just wear a mask at home for a few days, and get over the adjustment phase in a safe environment.

That's not science; that's arguing to a point.

Presumably, these doctors didn't die during last year's flu epidemic. Nor during the previous years or decades of their practice. So something is different this year. Something they normally do to protect themselves, that isn't working this year.

Hm, they use hand washing, gowns, gloves, masks. Which one, do you think?
