Also from the same article (blog, really): So now let’s get to the crux of it. Where are the personal dangers from reopening? When you think of outbreak clusters, what are the big ones that come to mind? Most people would say cruise ships. But you would be wrong. Ship outbreaks, while concerning, don’t land in the top 50 outbreaks to date. Ignoring the terrible outbreaks in nursing homes, we find that the biggest outbreaks are in prisons, religious ceremonies, and workplaces, such as meat packing facilities and call centers. Any environment that is enclosed, with poor air circulation and high density of people, spells trouble. Some of the biggest super-spreading events are: Meat packing: In meat processing plants, densely packed workers must communicate to one another amidst the deafening drum of industrial machinery and a cold-room virus-preserving environment. There are now outbreaks in 115 facilities across 23 states, 5000+ workers infected, with 20 dead. (ref) Weddings, funerals, birthdays: 10% of early spreading events Business networking: Face-to-face business networking like the Biogen Conference in Boston in late February. As we move back to work, or go to a restaurant, let’s look at what can happen in those environments. Restaurants: Some really great shoe-leather epidemiology demonstrated clearly the effect of a single asymptomatic carrier in a restaurant environment (see below). The infected person (A1) sat at a table and had dinner with 9 friends. Dinner took about 1 to 1.5 hours. During this meal, the asymptomatic carrier released low-levels of virus into the air from their breathing. Airflow (from the restaurant's various airflow vents) was from right to left. Approximately 50% of the people at the infected person's table became sick over the next 7 days. 75% of the people on the adjacent downwind table became infected. And even 2 of the 7 people on the upwind table were infected (believed to happen by turbulent airflow). No one at tables E or F became infected, they were out of the main airflow from the air conditioner on the right to the exhaust fan on the left of the room. (Ref) Workplaces: Another great example is the outbreak in a call center (see below). A single infected employee came to work on the 11th floor of a building. That floor had 216 employees. Over the period of a week, 94 of those people became infected (43.5%: the blue chairs). 92 of those 94 people became sick (only 2 remained asymptomatic). Notice how one side of the office is primarily infected, while there are very few people infected on the other side. While exact number of people infected by respiratory droplets / respiratory exposure versus fomite transmission (door handles, shared water coolers, elevator buttons etc.) is unknown. It serves to highlight that being in an enclosed space, sharing the same air for a prolonged period increases your chances of exposure and infection. Another 3 people on other floors of the building were infected, but the authors were not able to trace the infection to the primary cluster on the 11th floor. Interestingly, even though there were considerable interaction between workers on different floors of the building in elevators and the lobby, the outbreak was mostly limited to a single floor (ref). This highlights the importance of exposure and time in the spreading of SARS-CoV2. Choir: The community choir in Washington State. Even though people were aware of the virus and took steps to minimize transfer; e.g. they avoided the usual handshakes and hugs hello, people also brought their own music to avoid sharing, and socially distanced themselves during practice. They even went to the lengths to tell choir members prior to practice that anyone experiencing symptoms should stay home. A single asymptomatic carrier infected most of the people in attendance. The choir sang for 2 1/2 hours, inside an enclosed rehearsal hall which was roughly the size of a volleyball court. Singing, to a greater degree than talking, aerosolizes respiratory droplets extraordinarily well. Deep-breathing while singing facilitated those respiratory droplets getting deep into the lungs. Two and half hours of exposure ensured that people were exposed to enough virus over a long enough period of time for infection to take place. Over a period of 4 days, 45 of the 60 choir members developed symptoms, 2 died. The youngest infected was 31, but they averaged 67 years old. (corrected link) Indoor sports: While this may be uniquely Canadian, a super spreading event occurred during a curling event in Canada. A curling event with 72 attendees became another hotspot for transmission. Curling brings contestants and teammates in close contact in a cool indoor environment, with heavy breathing for an extended period. This tournament resulted in 24 of the 72 people becoming infected. (ref) Birthday parties / funerals: Just to see how simple infection-chains can be, this is a real story from Chicago. The name is fake. Bob was infected but didn't know. Bob shared a takeout meal, served from common serving dishes, with 2 family members. The dinner lasted 3 hours. The next day, Bob attended a funeral, hugging family members and others in attendance to express condolences. Within 4 days, both family members who shared the meal are sick. A third family member, who hugged Bob at the funeral became sick. But Bob wasn't done. Bob attended a birthday party with 9 other people. They hugged and shared food at the 3 hour party. Seven of those people became ill. Over the next few days Bob became sick, he was hospitalized, ventilated, and died. But Bob's legacy lived on. Three of the people Bob infected at the birthday went to church, where they sang, passed the tithing dish etc. Members of that church became sick. In all, Bob was directly responsible for infecting 16 people between the ages of 5 and 86. Three of those 16 died. The spread of the virus within the household and back out into the community through funerals, birthdays, and church gatherings is believed to be responsible for the broader transmission of COVID-19 in Chicago. (ref) Sobering right? There are helpful diagrams in the article, which won't copy over, that help to illustrate some of the examples.

I might have missed this being posted but it has a ton of useful (and new to me) information on the spread (the how) of Covid. https://www.erinbromage.com/post/the-risks-know-them-avoid-them The Risks - Know Them - Avoid Them A sample from the article but I recommend everyone read the full article and Dr. Bromage's background and disclaimers (also linked in the article). How much Virus is released into the environment? A Bathroom: Bathrooms have a lot of high touch surfaces, door handles, faucets, stall doors. So fomite transfer risk in this environment can be high. We still do not know whether a person releases infectious material in feces or just fragmented virus, but we do know that toilet flushing does aerosolize many droplets. Treat public bathrooms with extra caution (surface and air), until we know more about the risk. A Cough: A single cough releases about 3,000 droplets and droplets travels at 50 miles per hour. Most droplets are large, and fall quickly (gravity), but many do stay in the air and can travel across a room in a few seconds. A Sneeze: A single sneeze releases about 30,000 droplets, with droplets traveling at up to 200 miles per hour. Most droplets are small and travel great distances (easily across a room). If a person is infected, the droplets in a single cough or sneeze may contain as many as 200,000,000 (two hundred million) virus particles which can all be dispersed into the environment around them. A breath: A single breath releases 50 - 5000 droplets. Most of these droplets are low velocity and fall to the ground quickly. There are even fewer droplets released through nose-breathing. Importantly, due to the lack of exhalation force with a breath, viral particles from the lower respiratory areas are not expelled. Unlike sneezing and coughing which release huge amounts of viral material, the respiratory droplets released from breathing only contain low levels of virus. We don't have a number for SARS-CoV2 yet, but we can use influenza as a guide. Studies have shown that a person infected with influenza can releases up to 33 infectious viral particles per minute. But I'm going to use 20 to keep the math simple.

Trump has allowed this to proceed because of the Burr's committee concluded that Russia interfered in the 2016 election. Take note, GOPers, if you tell the truth about the Trump Swamp, they'll take you down.

I may have missed this, so apologies if it's been posted. -
If he had just done nothing but let experts handle it, it would have turned out so much better. But, he's an idiot who thinks he's a genius, who makes a mess of everything.

MAGAts love blaming others. It's everyone's fault but their's. A pathetic lot.

I don't believe the gov't is being stingy. I expect them to find a way to support the CFL. However, the CFL having no plan and having not even consulted with the union is terribly concerning. Gov't is right to holdout until they have a firm plan, with measurables, that has CFLPA support.

I guarantee these states will experience the following problems on election day: Long lines to vote Voting cutoff early Wrong addresses mailed to predominantly black-brown neighbourhoods. Fewer polling places Voting machine "breakdowns"

Ant they've been rigging the election for ages. It's a second world country with a good credit score.

To be fair, any drive that takes you out of Saskatchewan could be classified as the most enjoyable drive of your life. -
1301 Pembina? That doesn't sound right. 1330 Pembina is the Holiday Inn at Pembina and McGililvary. This looks like the property that has had the big question mark billboard for ages much further south. Good development for the city.

No one is putting cash on the table right now. That ship sailed a month ago. At least not meaningful cash.

I think Trump believes that you can get the virus from the test. I mean the man is so incredibly dumb, I almost guarantee that's what he's thinking.
-
I think this is looking at paid hours. So, if you're maintaining payments to all 80 people at 100%, they would not be captured. How long is this sustainable?
-
If they don't throw out the charges, Trump will have to pardon him. To be pardoned, he has to admit to guilt, which he's already done a few times. Trump is the swamp.

So here's just a few problems based on my years in gov't reviewing all sorts of funding proposals. I've seen stadium/arena proposals. I've seen plans to create 5 meter x 5 meter gardening plots. I've seen almost everything in size and scale under $500 million. I've also seen a lot of people coming forward who don't even know what they need. They can't articulate it. But... 1 - You need to come with a real plan. Sure, you can get through the door, gets someone's ear about your plight but, if you don't have a plan, waiting for gov't to develop one can be problematic. 2 - If you're relying on gov't to have a plan, you better have a lot of time and not be approaching them during a crisis. Like now. The gov't analysts are working OT already trying to come up with plans and formulas to tackle the bigger problems facing our economy right now. This is not a small ask. Someone needs to analyse all the data and determine what the economic impact would truly be if the CFL folded. Also, what are implications for bailing out the CFL? Who's next on the list? How much are you going to hand out and how do you pick winners and losers. 3 - If gov't is going to bail them out, they need a policy in place to rationalize it, which goes back to the previous issue. It sounds like the CFL has identified that there is a problem and have found some ways to contribute back through offer advertising but they haven't come with a plan. That's what I'm reading.

They don't even hide it.

There are no morals in the Alt-Reich.

I don't think advertisers would be very happy if everything went to PPV. They're TSNs partners too and all sides are suffering right now.

That's it, racism and bigotry. Also the most fragile, entitled bunch of babies - the GOP and their sheep. A man was shot dead while jogging. He's black of course. And, of course, the murderers are walking free. Racism in plain view and the people are wringing their hands about unkempt hair.
-
They already have an agreement with TSN. I don't think they'll just tell the CFL that it's okay, just go ahead and have PPVs.

What a joke of judicial system. There are zero checks and balances. Corruption in plain sight. It's a Banana Republic.

Aldo remains one of the largest shoe companies in the world, remarkably. The history of this company is fascinating. They take the latest trends, design their own shoe based on the trend, assemble it and get it on shelves in 6 weeks. They have (or had?) stores around the world.

I didn't. I read that it was baaaaaaaaaad, so didn't bother. Did you?
