Covid Definition and 88 Threads

Unfortunately this topic is relevant to me now.... CDC Guidance: https://www.cdc.gov/respiratory-viruses/guidance/respiratory-virus-guidance.html https://www.cdc.gov/respiratory-viruses/guidance/faq.html The CDC has generalized its exposure control guidance to respiratory viruses, not...

A New York Times article about the current controversy over origin of the COVID-19 virus. Titled: The Government Must Say What It Knows About Covid’s Origins Wide ranging but somewhat superficial, it does have about 15 links to references embedded in it though...

Where I am in Australia, there has been a lot of media talk that Covid vaccines were useless in slowing the spread. It reduces the severity and death rate - no question. I have seen reports that if you have the Covid booster, you are significantly less likely to die...

We've been speculating about this happening for a couple of years: https://www.cnn.com/2023/01/23/health/fda-covid-vaccines-strategy-shift/index.html I think at this point most of us saw this coming, but it will still be interesting to see how the transition happens, both for the vaccine and...

It looks like backlash against China's ZERO COVID policy is finally causing its end. The upside is they succeeded in delaying mass infection until (presumably) everyone was vaccinated. The downside is now they're getting the organic mass infections they'd been largely able to prevent until...

We have lots of different COVID threads (some on vaccines, some on individual variants, etc.), but none on its long-term effects. I wasn't sure where to place this recent news item (and others like it), so I thought I'd create a thread solely devoted to it. Here is said recent news article...

Viral particles linger in brain cells. The analysis detected much higher average levels of two SARS-CoV-2 viral proteins they measured—the nucleocapsid protein and the spike protein—in blood plasma samples collected between six and 12 weeks after diagnosis from patients infected with COVID who...

So north Korea announced its first COVID outbreak a few days ago and now nearly 200000 people caught the "fever with unexplained causes". North Korea itself has poor medical and anti Covid tools due to persistent sanctions against it. What do you think this will mean for the country and Kim Jong In?

Just an FYI to the American users of the forum: you can go to covidtests.gov to order free at-home rapid antigen tests. (source: NPR) Unfortunately, the tests will likely arrive after the peak of the Omicron wave (or at least I hope Omicron is on the decline by the time the tests start...

I am studying Data Science in University right now and because of COVID lessons are 95% online. I have to watch the webinar for 2 whole hours and because of that my grades are dropping as I have no mood to study. Academics asides I also felt socially disconnected in my school because I can't see...

It is well known that RNA viruses mutate very quickly. Hence, it is said that it is very hard to develop an effective vaccine against it. With HIV and influenza RNA viruses the scientific world is still facing difficulty in developing effective long-term vaccines against them. Most influenza...

I check this pretty regularly so I am sure this is a recent adjustment. China made a similar adjustment last year, around May adding 1200. The UK too some numbers off towards the end of last year (around 5,000?) How does this work? This spike seems very large...

Like the name, are all 3 shots of Pfizer Covid vaccine identical in composition or they are different formula following the mutation of the virus? I took all 3 shots, just curious whether it's more of the same.

In this thread I'd like to explore the substantial impacts that SARS-2 becoming endemic will have on future life, economy, travel, the healthcare system and social life in general. For starters, it seems high inflation will be the norm. Some economies will likely crash and most will become...

I was wondering if anyone had any data on the effectiveness of Covid policies on Covid transmission. Ill start, keep in mind my information comes from an email I was sent by the college and their site not a research paper, at Merrimack college masks are currently required in "certain indoor...

I want to know about this thing.

Background: While discussing a moderator action in the private forum a statement was made that points to a potentially fundamental misunderstanding of how vaccines/vaccinations work that may be pervasive regardless of which side is correct. I'm spinning that discussion off and re-starting it...

I thought it might be interesting and helpful to put all information on known side effects of Covid in one thread. Please feel free to add any information on side effects here...

If someone has had the original COVID-19 strain and survived, does this mean that they have any immunity to the new variants? Or do the new variants completely ignore any antibodies that someone who survived the original virus has?

I know lots of people here are in undergrad or graduate school (some maybe even as faculty). I'm curious how your institution is handling the return-to-school process in the midst of COVID/Delta? Are you at 100% capacity? Maybe 50% (with a hybrid online mix, for example)? Will masks and/or...

Anyone have research on whether it's necessary and/or a good idea to get one? Pfizer has said it's vaccine efficacy drops to 83.7% after 4 to 6 months...

As the Covid vaccines become more prevalent worldwide, the hospitalization and mortality rates are coming down hearteningly. Actually, what happens after vaccination? 1) Vaccination causes the production of antibodies. So when later infection happens, the antibodies are up and ready to bind...

Peter is a Nobel Laurite researcher who was going to retire just after Covid hit. He put off his retirement to work on Covid and has released a book about the experience: https://www.booktopia.com.au/an-insider-s-plague-year-peter-doherty/book/9780522877519.html Looks interesting. I will be...

https://onlinelibrary.wiley.com/doi/10.1002/jmv.26958. Since the majority of Covid cases are mild or Asymptomatic one possible factor could be existence of cross immunity in a population as a result of previous exposure to other Endemic Coronaviruses.

Here's a nice news piece from Nature summarizing various studies to find the underlying causes behind the neurological symptoms associated with COVID-19. In particular, the article highlights studies suggesting that SARS-CoV-2 can infect astrocytes in the brain, that SARS-CoV-2 can affect blood...

I know even the best vaccines aren't 100% effective at preventing infections and there are lots of people who take immunosuppressants whose immune systems don't mount the proper response to the COVID vaccines. Other than these specific folks, I'm wondering what other reasons there might be for...

I was wondering if @Ygggdrasil has more information on this. Is there only documentation on people over 80? What is the likely hood that this would also be the case for those younger? I believe the study is only for the Pfizer vaccine. https://www.nature.com/articles/d41586-021-01299-y Is the...

Man this is killing me (figuratively I hope). I know I’m whinging, but I rarely get sick, and here I am experiencing full on flu symptoms along with a slightly discomfortable chest after the 2nd Pfizer. In addition to the sore arm. Being sick sucks, especially when it’s fake sickness meant to...
