1/ Remember when England had restrictions like the ‘rule-of-six’, 10pm curfew, Tiers. Our paper now published in @bmcmedicine looked at how these restrictions impact the number contacts people have. Quite relevant for when we move out of lockdown. bmcmedicine.biomedcentral.com/articles/10.11…

Today's post is for anyone with bdays this time of the year. Including our Exec Director, an expert in "combo Xmas/bday" presents! Happy birthday Neale! On that note, ever work with multiple date columns but need to pick one? Use coalesce() to easily prioritize a value! #Rstats

I haven’t been here in a while but I’m now trying Bluesky bsky.app/profile/jarvis… come say hello

I haven't tweeted for a long time. Post Covid it didn't really feel like there's much point now I'm going to try this bluesky thing bsky.app/profile/jarvis…

Our paper describing Social Contacts and Other Risk Factors for Respiratory Infections in an IDP population in Somaliland is now published. 🔗doi.org/10.1016/j.epid… "We observed a high prevalence of risk factors and high <5 mortality. Most contacts were made at home." 🧵(1/17)

Over 4 mill people have been forced to flee Ukraine. We describe some of their healthcare needs. Thanks to colleagues on ground in Poland and Moldova for input.@DanielaFuhr @bayardroberts @Jarvis_Stats @martinmckee @UkrainianMedic1 bmj.com/content/377/bm…

More than 4 million people have fled Ukraine. This vulnerable population will have both immediate and long term healthcare needs. @adriannakmurphy @bayardroberts @DanielaFuhr Anna Tarasenko @Jarvis_Stats @martinmckee offer some guidance bmj.com/content/377/bm…

@RuwanEPI @PLOSNTDs @flavio_finger @tmorris_mrc I think you'll like this one. Combining your ideas with some infectious disease simulation.

Consistent across wide age bands. The timing is similar to when Plan B was active. Though it is reported mask use and not actual, so may just be people realising they should say they should wear a mask rather than actually wearing one. Lots of people say they wash their hands!

We ask 3-4k people a week did they wear a mask yesterday. England (in green) drops to below 75% from Aug 21 to early Dec 21. From late Dec until a couple of weeks ago it was 85%+. In the last two weeks, we saw a drop to below 75%, whilst remaining high in Scotland.

Please note CoMix will stop collecting data in the first week of March. We expect to do the final routine report on the 8th of March and then we'll look to more in-depth analyses and get the data sorted for everyone to use. Full report here: cmmid.github.io/topics/covid19…

This could be that 18-29 are more likely to live with 2 or more non-family members for contacts in the home. For outside the home, it's driven by a small number of people who record a lot of contacts (50+) whilst reporting they're in isolation.

This latest CoMix report is online. We spent some time exploring the contacts of those in isolation or not in adults (and testing +ve). Lots of uncertainty due to low numbers in isolation (2-8% at various points of the survey). cmmid.github.io/topics/covid19…

@n3113n @BMCMedicine @KevinvZandvoort @amyg225 @kerrylmwong @EpiPose @cmmid_lshtm @LSHTM Yep, I'll add a graph to the report this week on their contacts. We do the proportion in isolation or quarantine in the reports by age. This was the graph in the last report.

@Jarvis_Stats @BMCMedicine @KevinvZandvoort @amyg225 @kerrylmwong @EpiPose @cmmid_lshtm @LSHTM Do you record whether respondents are in self isolation when they completed the survey?

@matthew_quaife @QuentinLclrc Adding marmite to mild cheddar makes it taste more like mature cheddar. Secretly making weak cheese seem strong for decades now!

@QuentinLclrc Hi guys, the option for "obviously both" isn't showing for me - must be some sort of Twitter error, please investigate

Controversial debates at latest #KnightGroup meeting today, please help us settle these two (equally?) important issues! No particular context, just pick one. 🍽️Question 1:

When you have a PhD, Professor in your job title, multiple degrees, and your mum just destroys you at wordle.

And all of the previous reports are here cmmid.github.io/topics/covid19… Maybe one day it will make a nice case study of how some real-time reporting evolved over two years. For now, it just reminds me that running a study, cleaning, and analysing data at the same time is tiring.

In even longer the full report is here cmmid.github.io/topics/covid19…

Just put our 70th report for #ComIx online. As well the routine one we looked at Xmas contacts for 2020 and 2021. In short, Xmas 2020 and 2021 are quite similar and look quite like the third lockdown to me. I think this is the first time this kind of thing has been measured?
