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

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.

⏩ 2 years to 2020. Water burst thru walls on 2 sides of my bed. Revealing walls, subfloor, crawl space filled with mold due to construction defects

#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.

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

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.

📊Our #wastewater dashboard is updated! 👉 Check out for the latest #COVID19 WW trends.

Data Analysis from our #epidemiology and #datascience teams: 👇 🧵1/4
As of Feb 16, 2022, our national #wastewater #data has fallen 📉 by 95% of the nationwide #omicron peak seen at New Years.🧵 2/4
National levels are back down to what we saw in summer 2021, which is 70% lower than the Delta peak (Sep 2021). BUT ‼️ wastewater concentrations are still 6.5X higher than levels seen during the trough of the pandemic (May 2021). 🧵 3/4

I recognize a lot of names in the list of authors




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…

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

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"


#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!

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)

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.

#BirdFlu #AvianFlu #influenza #cranes #H5N1 #Zoonotic #Israel
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.

New research from @JohnsHopkins about maternal health!

Vaught AJ, Minhas A, Boyer T et al. Incidence of essential hypertension but not echocardiographic abnormalities at four years with a history of preeclampsia with severe features.

#ph260720 #Moms
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.

Yesterday I sat on my front porch and watched kids across the street running a lemonade stand. They were laughing and having so much fun. Despite their masks, it was one of the most “normal” things I’ve seen in months. (2/28)

1/ 🧵A picture is worth 1,000 words 👁 #COVID19:

This 🎥 shows a clear example of what can happen to a person’s body w #COVID. His wife asked me to show it on twitter & urges everyone to get #vaccinate

(w/ consent of pt & wife)

#MedTwitter #NurseTwitter #CriticalCare
2/ You’ll notice his eyes are swollen shut. (Written perm to show). This is not fluid. It’s AIR from inside his chest leaking out his lungs 🫁 through muscles & skin to his neck & into his face. He is AWAKE & communicating but had ICU #delirium earlier.

#MedStudentTwitter #Nurse
3/ Look at his chest CT. See the “L” lungs w #Covid pneumonia/#ARDS & also AIR leaking out under his skin. Now go back to 1st tweet & watch 🎥 again. This is called “barotrauma” & happens when the 🫁s get too stiff and pop. Difficult situation. We’re hoping he can heal!

So #ICYMI #OnThisDay in 1974, and into the following day, was the #Tornado #SuperOutbreak This montage of images is on the @NWS pages at: Image
I have the following image as a poster in my office for several reasons, which I will expound upon in subsequent tweets. Firstly it was produced by hand by Theodore ‘Ted’ Fujita, who developed the F-scale (later the EF-Scale based in wind intensity and damage. Image
What I really noticed in the key/legend on the map was how he was also looking at the type of structure where fatalities occurred, something that other scientists (@StephenMStrader) were looking at before I came along, but once you start, you can’t stop. I’m pretty much obsessed. Image

Following some hoopla that my tweet 👇🏻 caused…

1. I want to applaud all the medical workers in #Montenegro - epidemiologists, support staff, technicians, nurses, doctors - who are at the front line, caring for the many sick people in the hospitals around the country (🧵1/10)
You are the unsung heroes!

I want to make sure that what I’ll say is #not meant to indicate that the #services you provide in 🇲🇪 are not good - I know that you are doing your very best, and I thank you from the bottom of my heart (2/10)
*reminder: health services is not a synonym for health system

My comment that it doesn’t make sense to use #CFR (or as was referred to ‘lethality’) for comparisons between countries, and as a mirror of the quality of health system quality is based on the following facts (3/10)
