AI synopsis
The group exhibits balanced support for the article's findings, referencing median R values like 1.28 for seasonal influenza and comparing them to higher R estimates for COVID-19 variants, which highlights ongoing debates about infectiousness. Words like 'much less' and 'significantly lower' reflect a tone of clarification and validation, while references to historical pandemics and contemporary variants demonstrate sustained engagement and perceived impact on understanding viral transmission.
Most discussions support the findings that influenza has a median R of around 1.28, aligning with the article's conclusions, though some debate the precise values and their implications.
The posts show moderate interest, with many referencing specific R numbers, historical pandemics, and debates about contagiousness, indicating engagement but not overwhelming enthusiasm.
Several discussions delve into detailed analysis of R values across different viruses, comparing influenza with COVID-19, and referencing various studies, demonstrating deep engagement.
The discussions help clarify the importance of R in understanding transmission, emphasizing how these estimates influence perceptions of contagiousness and policy, thereby having a moderate but meaningful impact.
At the start of each flu season, estimates of R are around 1.3 on average (e.g. https://t.co/DqGpsr2gSL), and drop below 1 at end of season (because epidemic declines). So at start of each epidemic, the infection spreads at least 30% more easily than it did at end of last one. 4/
So if H3N2 initially had an R of around 1.8 in 1968 (https://t.co/DqGpsr2gSL), and we wrongly attribute all of the season-to-season increase in R to an inherent increase in viral transmissibility (rather than evasion of existing immunity), what do we end up with? 5/
That also explains why we didn’t have flu during mask mandates. “The median R value for seasonal influenza was 1.29 (IQR 1.19-1.32)” So, much below 1.66 So, w/ mask mandates any airborne pathogen of Reff < 1.66 would be gone. 2/ https://t.co/8SG60uioZJ https://t.co/QPa4LhIZNd
3) For the avian influenza H5N1, it was estimated in 2006 at : ▶️ 1.14 ([IQR]: 0.61–2.14). We still don't have data of course, for the actual clade. Number was lower as seasonal influenza which was estimated at : ▶️ 1.28 (IQR: 1.19–1.37). Refereence https://t.co/c6KIcKV5mE https://t.co/MsZ8fm47Rq

The local prevalence of 23.2% is already quite high and while I am uncertain what the exact R0 (R naught is the estimate of contagion) is for what's circulating, a review from a decade ago (PMID: 25186370) showed a median R0 of 1.28 for pandemic influenza... pubmed.ncbi.nlm.nih.gov/25186370/ 3/11

@BoomslangCreate @b_chinnian5 @HelenBranswell @USDA IIRC the current virus has some PB2 mutations that help achieve efficient replication but those mutations are low hanging fruit the rest are harder to acquire so until then there can only be limited human-to-human spread (as has happened for decades) https://t.co/S40AJ2WsVW 2/2

@Horatioyuletide @ResilientsTv @19joho @AngryCardio @jsm2334 Chew on this: According to this paper, the median R0 for the 1918 pandemic is estimated at 1.8. But that pandemic spread faster than SARS-CoV2! How is the R0 1.8 while Omicron is what, 8.0 or something? Yet spread slower? Math says this is all bullshit. https://t.co/jYDNgWbFqe
@TotalCytopath @arijitchakrav @19joho FYI: Unless you think >40% of the population was infected during the first wave of the 1918+ influenza pandemic (in which case you'd be wrong), its initial wave ended without herd immunity; i.e. R decreased below 1 without herd immunity. https://t.co/gVpW2BDVlT https://t.co/7jLVyVzmBl
@falsel_net @evly843 @JPWeiland The BA.2.86 estimates still have way too little data—need more.

Flu is spread between people by respiratory transmission. Seasonal flu viruses tend to have an R number that is slightly above 1 at the start of an epidemic. https://t.co/KnUpe4Wmj5 By cutting the amount of contact between people, social distancing could have a large impact.

@graeme_0 @pennie_reese R0=1.28 estimated for seasonal flu. That gives H=1-1/1.28= 22% herd immunity to prevent exponential spread—a pretty low threshold. If the flu vax is only 50% effective then 44% vaxed gives herd immunity. RSV has much higher R0—and there's no vax. https://t.co/zR0tZGofJH

At the start of each flu season, estimates of R are around 1.3 on average (e.g. https://t.co/DqGpsr2gSL), and drop below 1 at end of season (because epidemic declines). So at start of each epidemic, the infection spreads at least 30% more easily than it did at end of last one. 4/

How much worse ? Well .. the 1918 flu that killed millions ? That had an R0 value of 1.8 which is bad https://t.co/o3XZBZ2WLb
@KarlPettersso10 @sdbaral Is the R of seasonal flu really that low? This study suggests a medial value of 1.28 I think. Not sure what a modal or mean value might be. https://t.co/s8Hcj9vRZj
Here's some perspective; The median R value for seasonal influenza was 1.28 https://t.co/DoPGY1QWH1 https://t.co/xsLzho9ecA
@StuartLancast73 @Beepr5 @RealJoelSmalley @jengleruk Flu has a much lower R [1.28–1.80*] than SARS-CoV-2 [3.6–5.8†], i.e. much less transmissible... ...interventions to prevent spread of the latter were thus much more effective against flu.

@GKeferstein @jneill @TheEliKlein @CovidSerology Do u see flu around? Back to the point: https://t.co/gfNC0M7on0 "median R value for seasonal influenza was 1.28 (IQR: 1.19–1.37)" https://t.co/JeEuRBGpKU https://t.co/3rkYrn3XLD https://t.co/5vkdq2I6Q4

@ShallBeFree7591 @DebCameron3 @CelestineBee Okay then, here is some updated information on both the reproductive values of both covid and seasonal influenza. Covid : R =2.2 Flu : 1.7 https://t.co/YhnO2goeyn https://t.co/dzbL6TRUuf
R0 for seasonal flu: 1.3 https://t.co/4HHTbE8dF3 R0 for "normal" SARS-CoV-2 is ~2.5 https://t.co/KP5VNOXdpG Ref for R0 = 4,3 med B.117 som dominerende variant https://t.co/igk5czTgrZ
@josefinbonnevi @veteprotein Det finns R0-uppskattningar för influensapandemier, och de brukar hamna litet lägre än för COVID. https://t.co/4yz6JCrOpt

RT @MarkChangizi: Reproduction number (R0) around 2 for COVID 19, a little higher than the typical value for seasonal influenza outbreaks.…
@Fannymcslap @gardainfo R rates are the same https://t.co/Bii3rKzhQo
12/ What is the typical R0 attack rate for the seasonal flu in most years? It’s around an R0=1.28. The 2009 flu pandemic? R0=1.48. The 1918 Spanish Flu? 1.80. This new #WuhanCoronavirus reproductive value again? R0=3.8. (Flu reference: https://t.co/ek0aA8GpoE …)
@boucher7_wayne @JustinTrudeau 1.5 million vaccinated. That's 1.5x the number of total covid cases! 918,000 cumulative cases. 864,000 resolved cases. 22,545 deaths 31,455 active cases Covid transmission rate 0.98-1.1 over a year.

@globeandmail The median R(t) value for seasonal influenza is 1.28. COVID estimates of 2-7 were used to justify mass lockdowns. What changed? https://t.co/mYubFlvfJC
@kerpen Aside from flu pandemics (1918, 1957, 1968, 2009), the median estimate of R0 for seasonal flu is 1.28. Rhinoviruses are not subject to as much surveillance. But if 1.88 is close to correct, suppression would be more difficult. https://t.co/5XgZuiTLvG https://t.co/JayVO4HFdN
@JennyCa11376273 @simondolan Are you suggesting there is little data for influenza?

@SplitSplatJones @mattwood2012 @DrCharlesL Transmissibility. Seasonal flu has an R rate of 1.3 (https://t.co/al8rSuletg). Coronavirus has an R rate of 2.5-3.5 (https://t.co/dnwrYaBynZ). Coronavirus is, broadly speaking, twice as easy to spread.

@ibspinksin @firefly4f4 @carldemaio Study on the contagiousness of the flu: https://t.co/WnRLy6KSFh COVID-19 has more uncertainty, of course, but the CDC has some references under Table 1 here: https://t.co/OhPcNGDo7N From what we know so far, COVID-19 seems to be 2-3 times as contagious as the seasonal flu.

@nay_sue1 @buybuydandavis Sure, something like that. I was looking for a source. This estimate was 1.28. https://t.co/sOrRbNJNia So, I don't understand your point. That shows that it's much more infectious.
@BrianUkulele And the R for seasonal flu is about 1.3 "Twenty-four studies reported 47 seasonal epidemic R values. The median R value for seasonal influenza was 1.28 (IQR: 1.19-1.37)." https://t.co/I5wltsn4d4

@glovepurse @bofackson @davidsonmark650 @StephHQU1 @ScottAdamsSays @kat_anan believe whatever you want, but R0 of SARS-CoV-2 is 2-3x that of seasonal influenza; IFR is 3 to 15x higher.

@ButylFutile @vallenduuk_ie @Jackairy @OwenJones84 (1) "the flu" isn't a single virus, (2) we've historical data on various flu outbreaks w/ high confidence on their R value, and know covid—19 can't be treated as if it were as contagious seasonal flu (as has been done by GOP politicians & some media (Fox)) https://t.co/CzychGpicq
