CDC ditches 5-day Covid isolation, argues Covid is becoming flu-like

Hospitalization and death is different, long covid is different, and they mention both, specifically.
Even WSJ coverage of this emphasized that point, and it's hardly a liberal rag, phrasing as "Treat it more like flu" not that the disease itself is flu-like.
On the contrary, WSJ point out:
However, public health officials cautioned that Covid still isn’t the same as the flu or other respiratory viruses. “Let’s be clear. Covid-19 is not the flu,” said Jackson at the CDC. “It still causes more serious illness and leads to more lasting effects,” he said.
Public-health experts and physicians note that Covid is still a disease that is cited as a cause of death in more than 1,000 people a week, according to CDC data. And long Covid, with symptoms that can linger months and even years, hasn’t gone away.

Finally, CDC didn't ditch 5 day precautions. The part most coverage isn't headlining, CDC say if you're not isolating, wear a well-fitting mask, keep your distance from people, for five days.
They also say during that 5 days have clean air, which they define as outside air, higher fresh air mix, and purification. An office demanding people come in should ask their building if they've adopted the post-pandemic ASHRAE directional guidance (not yet formalized).
With recent research attributing long covid brain-fog to leaking blood in the brain, and research is still finding other unexplained effects, it may be worthwhile to weigh that we have a pretty good handle on the flu, but ...
TL;DR: We are still learning about this thing.
FTA: "The CDC acknowledged that the eased isolation guidance will create 'residual risk of SARS-CoV-2 transmission,' and that most people are no longer infectious only after 8 to 10 days. As such, the agency urged people to follow additional interventions—including masking, testing, distancing, hygiene, and improving air quality—for five additional days after their isolation period."
Given that many people were ignoring the prior advice before this advice came out, I doubt it will effect little change. The same recommendations should have been applied to all influenza-like-illness even before Covid, but people mostly just try to work until they can't, then stay home until they can, and come back to work anyway.

A very pragmatic position but not one that has much to do with the science of sars-cov-2 shed duration or infective window.
As one of the rare few, I'd rather not take risks, especially since there's still so much developing science behind the long term effects of COVID. Good to know the CDC does not in fact care about disease control for those who heeded their advice up until now.
That's just not how it works though. Each subsequent infection increases the risk of bad outcomes (1)
The CDC must know this

https://www.theguardian.com/world/2023/jan/23/repeat-covid-i...
It is unarguable that the risk of the first exposure to a novel virus is much greater than subsequent exposures. I say this because T-cells generalize across mutations. And T-cells stay tissue resident for years to decades (unfortunately sars-cov-2 IgG and IgA antibodies are gone by 6 months).
Your T-cells from the first sars-cov-2 exposure will start killing infected cells much faster once you've been exposed. This limits the replication earlier and reduces the viral load. This reduces damage done.
Weird side effects like the collection of things called long-covid have been shown in study after study not to be related to viral load. So whatever risk is associated with reinfection does not decrease in that sense. But in the dying sense? It decreases a lot.
I have heard of some people whose second case of COVID (Dec 2023) was significantly worse than their first (summer 2022). This might be due to the amount of time since last vaccination, or the amount of exposure to an infected person. But I was interested to hear from a couple friends that the second time isn't always lighter than the first.
Spreading respiratory viruses is really called living in a normal human society, and for whatever reason medical professions abandoned every conventional advice and emergency plan of the past that was prepared for responding to novel respiratory contagious disease of the sort a coronavirus would be, that spares the vast majority of healthy people, and resorted to what I call Open Air Surveillance Fascism.
I'll never forget the absurdity of healthy people on a beach, which was probably the safest thing a person could do with maximum ventilation and full sunlight, with some moron shaming everyone while dressed in a reaper outfit.
First I had muscle spasms and twitches, then intermittent joint pain, trouble sleeping, hives on occasion while running, now exocrine pancreatic insufficiency that seems like it’s idiopathic (MRI is confirming today). I’m scared as hell and any attempt at diagnosis or treatment is a dead end or makes things worse.

NHS study from 2022: "Results Of 206 299 participants (mean age 45 years, 54% female, 92% white), 15% were ever labour market inactive and 10% were ever long-term absent during follow-up. Compared with pre-infection, inactivity was higher in participants reporting Long Covid 30 to <40 weeks [adjusted odds ratio (aOR): 1.45; 95% CI: 1.17–1.81] or 40 to <52 weeks (aOR: 1.34; 95% CI: 1.05–1.72) post-infection. Combining with official statistics on Long Covid prevalence, and assuming a correct statistical model, our estimates translate to 27 000 (95% CI: 6000–47 000) working-age adults in the UK being inactive because of Long Covid in July 2022." https://academic.oup.com/eurpub/advance-article/doi/10.1093/...
* I know someone that contracted Covid late fall of 2020 and is still disabled from Long Covid/PASC with daily fevers and fatigue. If they don't get a good night's sleep and eat enough, they're wiped out for 1-2 days afterward.
* Have another friend that is still dealing with smell and taste changes a bit over a year out. Luckily the "rotting garlic" smell and most everything tasting "bitter" (their words) has significantly improved. Now most things have a little bit of normal smell and some taste has returned.
* Another friend's step dad, in his mid 60s, had a heart attack and died a couple months after a week long hospital stay due to Covid. Hard to say exactly if Covid damaged something that lead to it, but his doctor thinks it's probably likely but can't prove it. He was maybe 25-30lbs overweight, which of course does raise the chances of bad outcomes from Covid, but no other chronic conditions like diabetes or COPD. He walked a few miles nearly every day before getting sick.
"Researchers analysed blood samples from volunteers in Southern China, looking at antibody levels against nine different influenza strains that circulated from 1968 to 2009.
They found that while children get flu on average every other year, flu infections become less frequent as people progress through childhood and early adulthood. From the age of 30 onwards, flu infections tend to occur at a steady rate of about two per decade."

Oops, I was wrong there, thank you for the link.
Reconstructing household transmission dynamics to estimate the infectiousness of asymptomatic influenza virus infections https://www.pnas.org/doi/10.1073/pnas.2304750120 "Symptomatic cases account for 68% (95% CrI: 63%, 72%) of infected children and 59% (95% CrI: 53%, 64%) of infected adults."
Nearly half of adult influenza a infections are asymptomatic and go unreported and untested.
Really? My understanding is that high fever and body aches are the distinguishing factors between flu and other illnesses, and I distinctly remember having the flu a few times (including when I had it a few years ago and was given a test to confirm). I'd be very surprised if fewer than 50% of the population had ever had the flu.
I would agree that people sometimes use the word "flu" to refer to things that are not actually the flu, but I doubt that there are that many people out there who have been around for ~4 decades but never got the flu.
On top, this is now the most contagious virus!
In our lockdown capacity, it demonstrate how fast the virus spread and how much damage it did with a population largely immunologically naive to Covid). I can only imagine what would have happened in the US had it just been business as usual.
Is "minutes" supposed to be "meters" or something else?
I often give my friends an example: we're on the beach in 20 meters away a couple is walking and you can smell their strong perfume. Aromas are molecules, alright, but viruses are not so much "heavier." They can be carried away pretty far away. Of course, the further you are, the smaller the chance gets, but it's possible. The longer you stay, and the more people walk by, the more real the chance of infection gets.

It's perhaps not impossible to get COVID from 30+ feet away, but I sure haven't ever heard of such a thing happening, nor have I seen any guidance that indicated this distance presents a risk.
TBH, I would think it would be more likely that the infection happened at a different time, when the kids were not actually 30 feet apart (even if they were supposed to be, and said they were). I say this as a parent, and as a former kid.
Measless is known to have infected people at a stadium 100 feet away [1].
Influenza is known to infect through dust particles [2]. I can't find the study, but this is valid outdoors, too.

It is possible, given the right conditions. My point was that if I can smell somebody's perfume from a great distance, I can also inhale their virus.
I was wearing a 3m respirator with p100 cartridges.
One because the paper masks were hard to find, two they reduce but do not eliminate the risk of infection, and three those cartridges last way longer.
Never caught it either.
I know people who never had symptoms, but tested because a household member had tested positive (with symptoms) and found out they were positive too - it happens.
In my opinion, that is the best case scenario - you got it, didn't know it and your body fought it off like a champ.
Definitely true. But there are some people who have been very careful and/or tested multiple times with every illness in the last 4 years, and who are fairly certain they have not had COVID.
You have and are doing the right thing to protect your health against a virus where about 250,000 medical papers all show is very bad news for humans.
Visitors from outside the US are still being able to walk in and get it as well.
YMMV etc. etc., but this is accurate in greater NYC area as of January/February 2024.

The second study uses a test with 13 question. I don't think you can ascertain IQ very accurately with a 13 question test (especially if the same test is given to people with a wide range of ages).
https://www.americanprogress.org/article/covid-19-likely-res...
Don’t you think we should wait a bit before putting credence in these studies? Just a quick glance is enough to see plenty of potential flaws.
Jumping at the latest study isn’t much different than “just trust me bro”. These things take years if not decades to understand. We’ve been wrong far, far too often to keep repeating this behavior.
But I agree with your sentiment. The first study doesn't follow people at all, and the second study has a 13-question test. IMO this is very overblown — these studies do not give cause for alarm that would justify shutting down the world again.
"The adverse cognitive impact was worst with the original (ancestral) virus and the Alpha variant, compared with subsequent Delta and Omicron variants"
https://erictopol.substack.com/p/long-covid-and-cognitive-de...
It seems like:
(a) Obviously they're not intentionally infecting one group and keeping the other in rigid isolation so ...
(b) it seems like it would be hard to rule out that there's something else that's characteristic of people who avoided infection which could be related?
To be clear, I'm not trying to throw skepticism at the conclusion that infection causes deficits -- but isn't it kinda hard to measure? In the same way that, e.g. it's hard to measure the very long-term effects of forever chemicals or microplastics or other things that are so inescapably pervasive.
Also look at Fig. 1 in the first study
> participants who had recovered from Covid-19 in whom symptoms had resolved in less than 4 weeks or at least 12 weeks had similar small deficits in global cognition as compared with those in the no–Covid-19 group, who had not been infected with SARS-CoV-2 or had unconfirmed infection
So they're not comparing people over time, they're comparing people who've recently had COVID to people who have not ever had COVID. Given that white collar workers like lawyers, consultants, and software devs can stay home and not get COVID more easily than blue collar workers like grocery store clerks and the like, it isn't surprising that there's a very small IQ differential here.
This is published in a very prestigious journal, so I'm hesitant to assume my critique is correct. But at first glance I wouldn't take this to mean that you're likely to lose any IQ points from getting COVID, especially now.
It also says
> Larger deficits were seen in participants who had SARS-CoV-2 infection during periods in which the original virus or the B.1.1.7 variant was predominant than in those infected with later variants
and
> longer-term persistence of cognitive deficits and any clinical implications remain uncertain.
I hoped the article would make some mention of how believable the results were, but no.
(Also, maybe mention that the pre-Omicron strains are not much of an ongoing risk and that those results, while potentially interesting, are probably unhelpful for informing future policy decisions?)
edit: It seems worse than this. Quoting the first paper:
> This invited subsample comprised participants who reported positive results on a SARS-CoV-2 test or who suspected that they had had Covid-19 and whose symptoms persisted for at least 12 weeks; participants who, as part of the REACT study, either had a positive result on a polymerase-chain-reaction (PCR) test for SARS-CoV-2 or were unvaccinated and had a positive test for SARS-CoV-2 IgG antibodies on an at-home lateral flow immunoassay device16; and participants who were randomly selected from the remaining REACT study population.
Eric Topol calls this a “prospective” study, although the study, fortunately, does not advertise itself as prospective. This is a retrospective study with an obviously biased study population. And the >12-week-symptoms group contains self-selected participants who may never have even had COVID!
Getting sick for 12 weeks sucks. Finding a detectable effect on an intelligence test should not be remotely surprising. Going from that to anything that should print COVID policy seems like quite a leap.
I wish we could have a culture of "wear a (good) mask when you're sick". I don't think I'm going to die from the Flu or Covid, but it is going to make life miserable for awhile.
I really don't want either one. Putting a piece of cloth on your face when you are/recently were sick really isn't much of a burden. I did.
The parent was concerned with reducing spread to others. Interestingly, one meta study [1] concludes that cloth masks are actually better than "good" masks if they are not worn and used correctly.
[1] https://academic.oup.com/jpubhealth/article/46/1/e84/7337687...
If sick people work an average N95/KN95 mask off of Amazon (which is the 'good' I was referring to), it'd help. It's not perfect, and you can do better, and you can do worse. But it's a reasonable intersection of "easy to do" and "effective".
> “Reported deaths involving COVID-19 are several-fold greater than those reported to involve influenza and RSV. However, influenza and likely RSV are often underreported as causes of death," the CDC said.
So it’s not that COVID isn’t as bad as it seems, it’s that flu and RSV are much worse than they seem. Seems like the guidance should be about how to spread all respiratory viruses less, not about how to be as bad at controlling COVID as we are at controlling the flu.
This would IMO be worth actual study. One would expect that what seem like basic precautions (wear a mask if you feel at all sick, stay home if you have or recently had a flu, RSV or COVID) should meaningfully reduce overall infection rates. But this may or may not be true in different contexts, and any of these precautions have costs as well. For example, keeping kids away from school seems fairly well established as being bad. Keeping kids from getting sick is not entirely obviously good for them. And plenty of people have allergies — making them all wear masks all the time has its own issues. (On the flip side, a decent, clean enough mask can help with some allergies. Choose your poison.)
(There are cases that people get wrong to degrees that seem absurd. I know someone who worked at a tech startup pre-pandemic. The founders knew that the startup had a norovirus outbreak and nonetheless kept themselves and everyone who wasn’t acutely sick at the office. If they had closed the office and switched to WFH for a few days to break the transmission strain, they surely would have had happier and more productive employees.)
If you know you’re sick, why not wear a mask? How hard it is really?
Not wearing a mask has zero impact on the person already sick. Them wearing a mask is 100% about being nice to others. There is no benefit to them.
Airplanes usually have pretty good ventilation and filtration.
I was wearing a mask early on in the SF Bay Area. Back when the health authorities were saying that there's nothing to worry about and that masks don't help anyway. I remember so many people giving me the stink eye for no reason. I guess my behavior was the "anti-science", tinfoil-hat stance back then.
Then it all flipped on its head pretty much overnight. And when later, having been vaccinated and having had COVID, I stopped wearing a mask out in the open, I remember the same people getting angry at that. But if you traveled 50 miles outside the SF Bay Area, the reactions were exactly the opposite.
It just bugs me so much that we find ways to turn every single thing into a culture war. We go out of our way to find reasons to lash out against others. I'm not sure if social media is the source of it, but it sure provides a positive feedback loop.
The virus has been naturally selected to make people this way. It's like cat owner brain parasites.
Cat people: We exist to serve.
Getting any type of evidence and research on this theory is impossible ethically and socially and even something like "are cat parasite infected humans more likely to oppose masks" is something that is impossible to test for even though its probably a factor because there's too many other strong social factors.
It's a fun science fiction theory at least and worth a think about how infections effect human behaviour.
I guess this is another result of an individualistic culture? A lot of Americans really don't like being told what to do, wear, or say. Even if it's in their best interest to do so.
https://www.thegauntlet.news/p/how-the-press-manufactured-co...
There are plenty of others I see (admittedly less so, but still daily in the affluent Bay Area) who drive around in their cars, alone, with masks on (non-Uber) and people who show up at the gym everyday wearing a mask while walking on a treadmill. I toured a preschool earlier this week where the teachers were all still required(?) to wear masks in the classroom (a bilingual Chinese immersion Montessori program).
Admittedly, I’m pretty anti-mask, and for those reasons: it dehumanizes interactions. That said, (for those still reading) I wish masks were a norm for when people were sick and carried no additional activist messaging. I fully support that use case and appreciate my fellow humans who wear them in those circumstances.
But then also, I’d expect those interactions to be rare, because if you’re sick you shouldn’t be hanging out with others, but self isolating.
That being said, there are many situations where it still makes sense:
- Feeling sick and on your way to pick up someone else
- Just dropped someone off and haven't taken it off yet
- It's not easy to take on and off so you just leave it on
- You're only driving for a minute and will need it when you get out.
So they're still wrong, but I see why they said it.
I wear a mask when out in public and my reasons, which are multiple, include but are not limited to "I have an immune compromised family member and don't want to be the one who kills them" and "I myself have been sick only once in the last 4 years and I'm pretty happy about that".
I’m about as liberal they come, and so are many in my circle. But not one person wore a mask for the sole purpose of not liking Donald Trump and then using a mask as a statement. That’s a bizarre take.
It may have been absurd how quickly masks were given up in red areas (don’t know; wasn’t there), but our laggard approach in Santa Clara county certainly was and felt reactionary.
Having been raised by 2 Republican extremists, I can tell you exactly why it was so politicized:
1. "YOU CANT TELL ME WHAT TO DO!" Is the refrain of government telling people what to do or not. And remember, that corporations are legally people, so the same applies.
2. Higher education leads to 'librul ideas', with things like gay people should have the same rights as straights, racism is still a thing, and other higher thinking. And this 'education' is seen as indoctrination.
3. Because of disdain for higher education (which is seen as indoctrination), comes the idea that "My upbringing is worth just as much as your book knowledge", throwing away bodies of evidence. Journals are equivalent to scribbles.
Once the sides were drawn, American polarization kicked in. There's no room for mere difference of opinion. The other side must be evil, stupid, and intent on destroying America.
I'd argue that that's especially true for the party in power at the time, though you have to take that with a grain of salt since I'm on the opposite side.
This always seemed rather optimistic. Flu rates are seasonal, and COVID could have been seasonal. But pandemic flus and particularly nasty flu strains also fade away because enough people either get them or get vaccinated that they are usually no longer so significant the following year. COVID lockdowns largely prevented this.
If the vaccines had worked anywhere near as well as an optimistic interpretation of the trials suggested, the lockdowns would probably have looked better in hindsight.
(Which isn’t to say that lockdowns didn’t have some value. If nothing else, they bought time for the vaccines to roll out and they may have contributed to a lot of people getting Omicron instead of earlier strains. It seems like Omicron was a decent amount less nasty.)
Masking/not masking became an overt way of signaling tribal association, and it was no accident whatsoever. Predictably, it caused untold numbers of unnecessary deaths.
One takeaway from all this is how willing and fervent people are to signal their group membership, even at the expense of personal life safety.
The right started out as "Covid is bad, but so is crashing the economy to prevent it", which turned into "Covid isn't that bad, wearing a mask is excessive", which became "The vaccine is more harmful than the disease". The left went from "Causing people to die is worse than any economy hit" -> "You should do everything possible to prevent it" -> "You should wear a mask at all times in public".
I often feel the left would have taken reversed stances if the right had taken the pandemic seriously. If Trump had advocated shutting things down and pushed strongly for vaccines/masks, it seems pretty likely the left would have called this an authoritarian overreach and/or highly questioned the safety of the vaccines.
In short, I think our culture is so highly polarized that as soon as something becomes a major topic, people immediately divide into separate 'sides' on it.
EDIT: follow-up question -- was the pandemic as polarizing in other countries besides the US?
https://www.thegauntlet.news/p/how-the-press-manufactured-co...
EG: even European countries that were more draconian earlier in the pandemic returned to relative normalcy, with less fear/debate around school reopenings, mandatory testing, mandatory masking, etc, sooner than the US.
In the US, sticky "showy extreme COVID vigilance is my essential identity as a good citizen" or "showy nonchalance is my essential identity as a free person" partisanship lingers.
Biden, Harris, and Pelosi all said in September 2020 that they won't trust any Trump vaccine. <https://www.newsweek.com/anti-vaccine-covid-trust-skepticism...>
When I finally contracted Covid (I was vaccinated + boosted in alignment with then current CDC guidelines), I ran the range of all the major symptoms like high fever, loss of smell, tachycardia, drop in O2 saturation, etc. Most of the symptoms persisted for several days before I began to recover and the tachycardia and O2 levels bothered me the most. I was actively monitoring my O2 levels and had they dropped much lower I would have gone to the ER as a precautionary measure. Even after the initial recovery, it took almost two more weeks for me to recover my sense of smell.
For me, Covid is no joke and it is absolutely insane to me how basic health precautions like wearing a mask to reduce transmission, isolating, etc have become politicized.
...or you're just fine catching covid outside of work but it's so much worse to catch it in an office
I think complete isolation could indeed have an impact. Another thing that I think we will see down the road is more super bugs due to the overuse of sanitizer during that period as well.
At the UK inquiry the Chief Medical Officer made the point that pursuing herd immunity via infection is deeply flawed and highly unethical. Given the population has gained little actual immunity to the virus so far and it continues to circulate all year around and has so disabled over 100 million people and killed at least 28 million and every week kills many thousands in the US its not going to stop. Covid is the third biggest killer in the world currently and the death count associated with it due to a massive reduction in testing is unfortunately enormously undercounted especially with the increase in heart attacks and strokes which Covid causes due to its vascular impact.
Covid is going to be an all year around infection that hasn't at any point dropped below 1 in 80 people carrying it, we need to use HEPA filters and UV light to clean the air indoors and adopt masking as a mitigation until we have better vaccines or treatments especially for Long Covid.
I've heard it said that current COVID-19 vaccines are counterproductive, because they only reduce symptoms as opposed to increasing one's chances of catching the disease, or reducing one's infectivity. Someone who has been vaccinated and infected is more likely to go to work or school and thus more likely to spread the disease.
