Conclusion Of The Article:

Wearing any type of face covering, even if it’s just a bandana, is vitally important to help reduce the spread of COVID-19. Please wear a mask. I would highly recommend reading this paper on the efficiency and potential effectiveness of cloth masks. I’ve copied the conclusion down below, but I urge you to read the article for yourself; please never accept something just because you saw it in a tumblr post (or any social media post).

Conclusion of the article:

“In conclusion, we have measured the filtration efficiencies of various commonly available fabrics for use as cloth masks in filtering particles in the significant (for aerosol-based virus transmission) size range of ∼10 nm to ∼6 μm and have presented filtration efficiency data as a function of aerosol particle size. We find that cotton, natural silk, and chiffon can provide good protection, typically above 50% in the entire 10 nm to 6.0 μm range, provided they have a tight weave. Higher threads per inch cotton with tighter weaves resulted in better filtration efficiencies. For instance, a 600 TPI cotton sheet can provide average filtration efficiencies of 79 ± 23% (in the 10 nm to 300 nm range) and 98.4 ± 0.2% (in the 300 nm to 6 μm range). A cotton quilt with batting provides 96 ± 2% (10 nm to 300 nm) and 96.1 ± 0.3% (300 nm to 6 μm). Likely the highly tangled fibrous nature of the batting aids in the superior performance at small particle sizes. Materials such as silk and chiffon are particularly effective (considering their sheerness) at excluding particles in the nanoscale regime (<∼100 nm), likely due to electrostatic effects that result in charge transfer with nanoscale aerosol particles. A four-layer silk (used, for instance, as a scarf) was surprisingly effective with an average efficiency of >85% across the 10 nm −6 μm particle size range. As a result, we found that hybrid combinations of cloths such as high threads-per-inch cotton along with silk, chiffon, or flannel can provide broad filtration coverage across both the nanoscale (<300 nm) and micron scale (300 nm to 6 μm) range, likely due to the combined effects of electrostatic and physical filtering. Finally, it is important to note that openings and gaps (such as those between the mask edge and the facial contours) can degrade the performance. Our findings indicate that leakages around the mask area can degrade efficiencies by ∼50% or more, pointing out the importance of “fit”. Opportunities for future studies include cloth mask design for better “fit” and the role of factors such as humidity (arising from exhalation) and the role of repeated use and washing of cloth masks. In summary, we find that the use of cloth masks can potentially provide significant protection against the transmission of particles in the aerosol size range.”

Of course, a simple cloth mask is nowhere near as effective as a respiratory mask such as N95 masks, and neither even touches the effectiveness of a full-body protective suit, but (a) not everyone has access to a fully-body protective suit or even to an N95 mask and (b) any face covering is better than no face covering. So if all you have to cover your face is a bandana, please cover your face with a bandana. If you have access to higher-quality cloth masks, utilize higher-quality cloth masks. If you have access to N95 masks, wear an N95 mask. Do as much as you can to keep the virus from spreading.

(Also please note the significantly higher risk if your mask does not fit; obviously this risk would be higher with bandanas, which are not typically made to fit snugly to the contours of one’s face. Still, bandanas are better than nothing.)

Stay safe! <3

I feel this could have been designed better.

URGENT ACTION UPDATE 2: DROP ALL CHARGES AGAINST ZARA KAY | Council of

31 December 2020 #JusticeForZaraKay #JusticeForZara #StandUpForZaraKay Zara Kay, an Australian citizen and

“Zara Kay, an Australian citizen and founder of Faithless Hijabi, was summoned to the Dar es-Salaam Oysterbay Police Station on 28 December 2020 and was held in police custody for 32 hours without an initial clear indication of charges.

“Zara is a well-known ex-Muslim and women’s rights activist. Faithless Hijabi, which she founded in 2018, supports women who have been ostracized or abused for leaving Islam. Whilst in police custody, Zara was asked about the work of her organization and why she left Islam.

“Zara was bailed on 29 December 2020 and told to return to the police station on 31 December. Her passport was also confiscated. This morning, at the police station, Zara was given permission to return on Tuesday 5 January 2021 with her lawyer. This is because stress caused by her initial police custody exacerbated Zara’s underlying health condition. Late last night, Zara had to go to the local hospital where doctors reiterated her diagnosis of Generalized Anxiety Disorder.”

Hi, @wokeurajoke-- that’s an interesting contribution to a post that was originally about schools reopening, although I’m sure you have your reasons. Your claim is correct on two points:

(1) You are correct in stating Democratic districts (not states) have higher death counts due to COVID-19. However, the large majority of these deaths (nearly a quarter of all COVID-related deaths in the US) occurred in just 12 Democratic congressional districts, all located in New York City. One can see how districts in NYC, a densely populated urban area, would have a higher death count than more rural districts.

In addition, while the initial surge of deaths due to COVID-19 was tragically large in Democratic congressional districts, and the death count is still larger in those urban districts than in Republican districts, the decline of deaths in Democratic congressional districts has “outpaced the national average” while Republican districts have seen significantly less decline, according to a Pew Research Center study published near the end of May.

Of course, any number of deaths is horrifying and tragic.

(2) You are absolutely correct in asserting that science is your friend. Wear a mask, keep social distancing, and most of all, stay safe!

716 billion dollars. Seven hundred sixteen billion U.S. dollars.

One billion is equal to a thousand millions. This is seven hundred sixteen billion. This is an insane amount of money.

Think of the millions of human beings on this planet who don’t have homes, who don’t have jobs, who wonder whether they’re going to be able to afford to eat tomorrow. Then think about the seven hundred sixteen billion dollars that we spent on the military. Just in 2019.

https://www.pgpf.org/chart-archive/0053_defense-comparison

This ^ source says it was 732 billion dollars from October 2018 to September 2019. I’m sure you could find different sources listing 705 billion, or 720 billion. The exact number does not matter. The fact is that there are people dying of hunger while this unfathomable amount of money goes to the military.

https://mkorostoff.github.io/1-pixel-wealth/

This ^ source isn’t related to the military budget or other government spending, but I found it to be useful in helping to understand exactly how much a billion is. We could help so many people with 716 billion dollars.

Because I remember disinformation being spread around the last election and I’m sure Russia will bring it back:

YOU CAN’T VOTE ONLINE.

YOU CAN’T VOTE FROM YOUR PHONE.

IN MANY STATES THERE ARE LEGAL CONSEQUENCES FOR PHOTOGRAPHING YOUR BALLOT.

DO NOT WEAR CAMPAIGN GEAR TO THE POLLS.

DO NOT TRY TO PERSUADE PEOPLE TO VOTE FOR A CANDIDATE AT THE POLLS.

DO NOT ENGAGE IN ANY KIND OF POLITICAL DISCOURSE AT THE POLLS.

NO ELECTION IS EVER A SURE THING, EVEN IF YOU’RE IN THE BLUEST OR REDDEST OF STATES. IF SOMEONE TRIES TO TELL YOU THAT YOU CAN SIT THIS ONE OUT, THEY ARE EITHER IGNORANT OR MALICIOUS.

VOTE.
