Neverending Covid-19 Coronavirus

Study links even mild Covid-19 to changes in the brain

Study: SARS-CoV-2 is associated with changes in brain structure in UK Biobank - Nature

Douaud and her colleagues evaluated brain imaging from 401 individuals who had Covid-19 between March 2020 and April 2021, both before infection and an average of 4.5 months after infection. They compared the results with brain imaging of 384 uninfected individuals similar in age, socioeconomics and risk factors such as blood pressure and obesity. Of the 401 infected individuals, 15 patients had been hospitalized.

The 785 participants were between the ages of 51 and 81 were all part of the UK Biobank, an ongoing government health database of 500,000 UK participants begun in 2012.

Douaud explained that it is normal for people to lose 0.2% to 0.3% of grey matter every year in the memory-related areas of the brain as they age, but in the study evaluation, patients who had been infected with the coronavirus lost an additional 0.2% to 2% of tissue compared with those who hadn't been infected.

While the areas of the brain most impacted appear to be related to the olfactory system, Douaud said it wasn't clear why that was the case.

Isaacson said the study findings were noticeable for clinicians, but he added that the overall impact on individuals was difficult to determine and could be small. "It's really hard to know the long-term clinical impact and quality of life impact in a situation like this," he said.

Heard this from someone who traveled to Florida recently.

The hotel they stayed out had signage stating "masks required". Yet only about 1/3 of the staff were actually wearing masks and fewer guests when in common areas.

When they asked the hotel about masks they were told this. "Our parent company, Hilton, requires us to put up the signs. You don't have to wear a mask though."

It's been like that in the entire South for like... the whole thing. Even before they repealed the mask mandates, it wasn't like someone was going to stop a maskless patron. No one wants to start a confrontation. So even when the city mandate was to wear masks and in buildings and there was signage everywhere AND all the staff were wearing masks, many folks down here just didn't and no one stopped them. =/

The city of NOLA being the one exception, but once you got to the suburbs, this was the case. Guess that’s why I got Covid twice.
 
It's like a whole different universe here, then. I think today was the first time I went to a store and saw anything less than 95% of the people masked. Even last week it was still almost everyone masked up with the mandate gone. Today it was still over half.
 
Had a doctors appointment at 8:00am this morning.

I put a KN95 Mask on (brand new, clean / fresh) when entering the building. I did not grab one of their tissue masks at the door. Get to the desk to check in and got chastised about my mask and not following directions.

They made me replace my mask or put a tissue mask on over my mask. I was like I just put this on, it's better than your masks. But nope. Rules are rules and this is to ensure I'm wearing a fresh mask.

I hate rules like these, but I understand them. It's because you can't trust people to be honest about these things. It's a sad state of affairs when in order to ensure that everyone follows the rules you need to unnecessarily police those who are following the rules.
 
Kids have been without masks in school for a couple weeks and I knew it was inevitable, boom Covid. Been miserable for a few days. My kids have bounced back much quicker than my wife and I. I guess 2 years avoiding it was a good run.

In totally related news, we are seeing an uptick in the B2. Omicron variant.

I have lost all faith in the CDC. For reference:
Government scientists confirmed Tuesday that there has been an uptick in the presence of Covid-19 in wastewater samples across the U.S.

later in the article:
“It’s too early to know if this current trend will continue or whether we’ll see a corresponding increase in reported cases across the country,” Kirby said. [Kirby being the CDC rep here]

Riddle me this, when has an uptick in covid in wastewater samples not precipitous of an outbreak in an area? We figured out that we needed to monitor wastewater because it gave us the best picture of disease burden in communities, since we are incapable of doing any other public health surveillance. How is our number one and only surveillance for covid infections suddenly become unreliable?

So stupid.

Covid cases are exploding across asia. This is worrisome because it could help breed new variants and the next global wave.
 
Looks like cases in the US were on a upward trajectory last week. Not a surge. An Average of 300 additional daily positives over the prior week. Probably likely due to mask mandates being lifted.

Right now we are seeing upward trajectory of cases, but not an upward trajectory of hospital cases. The reason cases are exploding across Asia now, is because they were good with containing and limiting spread of Covid by doing localized lockdowns in the past, so most of the population didn't contract the disease--which seems to be something that only Asian countries are able to collaborate well. In China, they kept Covid at bay for as long as they could, and now this very virulent strain is getting everyone sick because it's impossibly hard to not have it transmit across a population, even a very careful population. I expect to see the same sort of death trends over there that we saw here. I am wondering if over here we are approaching some sort of heard immunity. I know that the whole idea of herd immunity by illness is controversial, but I wonder if that's what's happening over here.

It seems to be. We’ve been rolling back on everything since the start of February, upto mandatory mask wearing ending on 28/2. There are still reasonably high case numbers but the deaths and hospital/ICU numbers are stable and low. I don’t know if our vaccine take up percentages differentiate us and the UK from a lot of other developed nations that haven’t had as high a proportion of the population take it up though 🤷🏻

We are seeing the same things, even in places like Florida where there was a low vaccine uptake. It feels like this is different, but I am concerned that another variant will pop up and make a bunch of people sick. I don't want to lull myself into a false sense of security, so I won't say that we are at herd immunity. I'm just wondering if we aren't too far off.

Yeah the talk of the mutant child of delta and omicron had me worried there for a while last week when I first read about it but then nothing seems to have exploded in the last week and my headspace seems to only be able to compute one impending doom at a time and Putin seems more dangerous right now…
