#Contact_tracing can be a practical and effective way of containing disease spread. But did you know it's even more effective when social groups are involved?
Check out our* new paper:
arxiv.org/abs/2304.10405

* @leahakeating @gleesonj @DavidJPOS @bolozna
1/6
Contact tracing not only cuts direct infection paths but can also prevent indirect spreading routes in groups. We illustrate how it can be more efficient than what would be predicted by models that assume a fully mixed population or a locally tree-like network structure.

2/6 Image
Our results show that the outbreak size shrinks as clique size, c, grows, and this is amplified by higher contact tracing success probability α, despite fixed transmission probability p.

1/ Epidemiology is a critical field in public health, and R is a popular programming language for epidemiologists to analyze and visualize data. In this thread, I'll highlight some essential epidemiology packages in R that you should know. #rstats #datascience #epidemiology Image
2/ The first package that comes to mind is "epitools." This package provides a suite of functions for descriptive epidemiology, including measures of disease frequency, tests for independence, and outbreak detection. #rstats cran.r-project.org/web/packages/e…
3/ "EpiModel" is another package that is useful for epidemiologists. This package allows you to build mathematical models of infectious diseases and simulate the spread of diseases through populations. #rstats cran.r-project.org/web/packages/E…

Before Twitter dies RT this 🧵

THEY KNEW

Remember the Emily Oster "LET’S DECLARE A PANDEMIC AMNESTY" in @TheAtlantic

I said there was going to be a bad study.

Well, BABIES under 6 mo old were hospitalized more than 65 to 74-year-olds!!!

This is what was hidden by the CDC Image
This was released on Nov 11th but if you look at the report they ended it in August.

Omicron was not mild for babies, and this was held til after the election. The @CDCDirector knew

This is why the #GBD wanted forgiveness and Oster's group

cdc.gov/mmwr/volumes/7…
All this talk about RSV and they left off many of these babies also had COVID.

I am so freaking mad.

This age group can't get vaccinated. Every reinfection they get will damage them more according to other studies.

They really just gave #LC to Gen Alpha

I'm @RRHDr, a #healthequity researcher & the Founding Director of @CARHEumn. My work seeks to manifest racial justice & liberation by making the invisible visible. This means that I start from the premise that racism is a fundamental cause of health inequity. #HardemanTakeover
Today I'm taking over @ia4phs to talk about #structuralracism and health from methodological innovation for measuring racism to its manifestations in our society from abortion access to policing. Structural racism as a #populationhealth crisis. #HardemanTakeover
Structural racism is a public health crisis, but it's also a FIXABLE problem!

2 yrs ago, to raise awareness for the #MillionsMissing due to #MECFS, I started a 🧵 on how tragic chronic illness has consumed my life

But I was too sick to finish, & shortly after uninstalled Twitter. Trapped by illness, unable to advocate.

2 surgeries later... 🧵, 🎬 2

1/
2017: I was Prof of #Epidemiology @PublicHealthUGA, researching #HIVprevention and #vaccine prep for emerging epidemics. I directed an epi training program @ICI3D. I loved my work & my amazing colleagues!

I was healthy & active 🚴🏄‍♂️ 🥁

Then, I bought a 🏡 and had it renovated. Jan 2018 I moved to the newly built master bedroom addition, I became sick.

#epidemiology time

Be wary of biases in how our brains interpret rates.

For example, a 100% increase (100 to 200) is undone by a 50% decrease (200 to 100).

I see this a lot in suicide reporting, where increases are breathlessly reported, but decreases are downplayed.

/1
Curious why that is?

The number set for decreases is 1 to 0. The number set for increases is 1 to ∞. So the increase "stretch" while decrease "compress"

100% up = 50% down
200% up = 66% down
300% up = 75% down
400% up = 80% down
500% up = 83% down
600% up = 85.7% down

/2
So the next time you see "suicides up 8%!!!" remember that:
a) there is a moral panic such that increases be headlines
b) there is a numbers bias to increases over decreases
c) year-to-year comparisons are relatively useless without trend analysis and error measurement

🧵. #Russia colonised #Ukraine in 18th century. Since then, they've been trying to exterminate ukrainian indentity and culture, to assimilate us into being russian. They appropriated a lot of our #culture, #history, achievements and personalities doing this. 1/ #twitterstorians
Foreword. Many of these examples might seem to you as insignificant or unconnected, but they all are evidence to the trend of generations of russians trying to unexist us as a nation, make Ukraine into what they think we are – "Little Russia" 2/
Let's get the obvious one out of the door. #Borsch is and always was Ukrainian. It got into russia with soviet diner menus. Now russians claim it's as intrinsic to russia as it is to us. Bullshit. 3/ A beautiful and tasty combo of Borsch, salo (lard in pieces)

(1/10) ❗️Disclaimer❗️: Not an #intersectionality expert but care about #intersectionality & #healthequity. I want my research to reflect personal values. Below are just some of my musings on this ⬇️
(2/10) In my #epidemiology research, often constrained by what data is available to me...

e.g. forced to conflate #sex & #gender, treat gender as binary construct, collapse #ethnicity into meaningless categories etc. This is not good research! ☠️
(3/10) Most importantly, not doing justice to the people my research is aimed to serve. Want to change that.

I recognize a lot of names in the list of authors

Colleagues

Mentors

They are wise, and know far more about #InfectiousDiseases and #epidemiology than I do

It is important to look at what this report does and does not say

covid19-sciencetable.ca/wp-content/upl…

@COVIDSciOntario
I don’t think there is anyone who would disagree with the message in these slides

Closing schools is a bad thing

Remote learning is disruptive and can lead to worse educational outcomes

As with everything in this #pandemic, poor and marginalized families far worst

But…
In this slide the #ScienceTable argues that vaccination reduces the risks to children

Currently less than 50% of the 5-11 cohort is double vaccinated

Once again the risk is greatest for our #children with comorbidities or low socioeconomic status

They admit they don’t know…

New research shows that only 10% #Omicron cases are in ppl who have gotten #COVID19 #Booster.

This may be MISINTERPRETED as:

"Only 10% of people w/ #BoosterDose get #OmicronVariant"

OR

#BoosterShots are 90% effective"

Not that simple! READ ON!

First, this is NOT a critique of the study (currently a pre-print).

Researchers at @MethodistHosp who did this provided a VERY valuable piece of info and are not making any inappropriate claims. Great work!

It's just that it's easy for public/media to misinterpret results!
3/

Paper reports on a total of 1313 #OmicronVariant cases in the Houston, TX area.

See table below:
~49% of cases in those not vaccinated (0 or 1 does)
~51% are #BREAKTHROUGHS.

Of those #Breakthrough cases,

535 cases w/ 2 #vaccine doses
140 cases w/ 3 doses (i.e., booster) Image

However mild #Omicron is, it is not a vaccine. There are deaths and hospitalizations due to this variant.

Stay away from misinformation.
Compared to Vaccination, natural infection could not protect population (against death or hospitalization) against any variant (Alpha, Beta, Gamma or Delta).

Proponents of Herd immunity are saying it again; #Omicron would provide herd immunity.

Evidence matters, not opinions
During delta wave, this is what we knew based on #Epidemiology of infectious diseases.
-This is not the last variant.
-There will be another wave.

Same would hold true for Omicron.

1/10 I write to share some updates re the current H5N1 outbreak in Israel from our #movement_ecology perspective, with aspects highly relevant to #epidemiology as well.

But let me start with some background first.

2/10 Around 12-13 December, the first observations of avian flu in cranes at the Hula Valley arrived, following three H5N1-positive cases elsewhere and in other bird species since mid-October.
3/10 With @SashaPekarsky and Idan Talmon, we then checked the situation with our GPS-tracked cranes, 11 of them were in Israel in the relevant period. We noticed clear movement/behavioral changes in few individuals.

In this new study, we followed up with women four years after they were diagnosed with preeclampsia during pregnancy. What type of research study is that?
#ph260720 #Epidemiology
Preeclampsia is a pregnancy-specific disorder that causes high blood pressure and evidence of damage to the kidneys and/or liver. Preeclampsia and other hypertensive disorders of pregnancy impact between 5-8% of births in the US.
