eg i guessed @suryasays family's jati after about 15 minutes (he was vague about this and had to ask mom)
a higher and higher % of DMs, emails, etc. to me are from indians asking about their genetics. since there are 700 million indians on the internet. makes sense
i'll be publishing my 6K-word essay in indian genetics https://t.co/ycMGoZh13z
but some general points 1/n
eg i guessed @suryasays family's jati after about 15 minutes (he was vague about this and had to ask mom)
indians have lots of structure which means non-geographical (jati) matter a lot. tamil brahmins more like UPites than other tamils
* parsies (75% iranian)
* bengalis (5-20% east asian)
the rough formula is 75% UP brahmin + 25% "native" (works for bengalis & south brahmins)

I held back from commenting overnight to chew it over, but I am still saddened by comments during a presentation I attended yesterday by Prof @trishgreenhalgh & @CIHR_IMHA.
The topic was “LongCovid, Myalgic Encephalomyelitis & More”.
I quote from memory.

#MECFS #LongCovid
The bulk of Prof @Trishgreenhalgh’s presentation was on the importance of recognising LongCovid patient’s symptoms, and pathways for patients which recognised their condition as real. So far so good.
She was asked about “Post Exertional Malaise”... 2/n
PEM has been reported by many patients, and is the hallmark symptom of ME/CFS, leading many to query whether LongCovid and ME/CFS are similar or have overlapping mechanisms.
@Trishgreenhalgh acknowledged the new @NiceComms advice for LongCovid was planned to complement... 3/n
the ME/CFS guidelines, acknowledging some similarities.
Then it all went wrong.
@TrishGreenhalgh noted the changes to the @NiceComms guidance for ME/CFS, removing support for Graded Exercise Therapy / Cognitive Behavioural Therapy. She noted there is a big debate about this. 4/n
That is correct: The BMJ published Prof Lynne Turner Stokes’ column criticising the change (Prof Turner-Stokes is a key proponent of GET/CBT, and I suspect is known to Prof @TrishGreenhalgh).

However Prof Greenhalgh then went off-piste.

Our preprint on the impact of reopening schools on reproduction number in England is now available online: https://t.co/CpfUGzAJ2S. With @Jarvis_Stats @amyg225 @kerrylmwong @KevinvZandvoort @sbfnk + John Edmunds. NOT YET PEER REVIEWED. 1/
We used contact survey data collected by CoMix (https://t.co/ezbCIOgRa1) to quantify differences in contact patterns during November (Schools open) and January (Schools closed) 'Lockdown periods'. NOT YET PEER REVIEWED 2/
We combined this analysis with estimates of susceptibility and infectiousness of children relative to adults from literature. We also inferred relative susceptibility by fitting R estimates from CoMix to EpiForecasts estimates(https://t.co/6lUM2wK0bn). NOT YET PEER REVIEWED 3/
We estimated that reopening all schools would increase R by between 20% to 90% whereas reopening primary or secondary schools alone would increase R by 10% to 40%, depending on the infectiousness/susceptibility profile we used. NOT YET PEER REVIEWED 4/
Assuming a current R of 0.8 (in line with Govt. estimates: https://t.co/ZZhCe79zC4). Reopening all schools would increase R to between 1.0 and 1.5 and reopening either primary or secondary schools would increase R to between 0.9 and 1.2. NOT YET PEER REVIEWED 5/
