@Redkiraz @dominiksteiger no, but interesting. in zurich, it also looks like its higher shedding per reported clinical case now:

@dominiksteiger Any ideas @trj2 ??

@will_townes @cduvallet cool! nice work! from this graphic, it also looks like concentrations are furthest away from the processing lab. Could sample shipment and storage influence measured concentrations?

@cduvallet We examined whether PMMoV levels in wastewater varied over space & time. PMMoV concentrations reached their highest levels in the Southwest. We hypothesize this may be due to regional differences in pepper consumption, but further data will be needed to confirm.

Spatiotemporal variability of the pepper mild mottle virus (PMMoV) biomarker in #wastewater : a new preprint with @CMU_StatDS PhD student Anna Rosengart and @WastewaterSCAN collaborators (incl @MarleneKWolfe ) arxiv.org/abs/2408.12012

@SeqH2O can i get one?

New lab mugs are in!

@Redkiraz The team updated the website, so it now shows trends with some publically available clinical information: wise.ethz.ch

@trj2 Thank you. Why don't we have a dashboard with ww situation for the whole of Switzerland?

Trad Mise à jour de notre surveillance des eaux usées (wise.ethz.ch): nous ferons une pause du 29/7 au 9/8, les tableaux de bord seront donc mis à jour le 30/7, puis seulement le 13/8 Cette date coïncide avec une période de creux habituelle pour les virus respiratoires

@Redkiraz We are working on a composite graphic that integrates data from all catchments into a single time series to add to WISE database. Is that what you mean? Or did you have something else in mind, besides the WISE and IDD dashboards?

@Redkiraz If there is a need to not have these breaks, its important feedback to us as we plan the future.

@Redkiraz Yes, we need to plan these things in advance, unfortunately SARS-CoV-2 did not cooperate with us. We resume sampling next week, so our dashboards will start to report results on 13th, 14th, and 15th, and the FOPH dashboard will have our data reported only on the 20th.

@C_Mellenthin thanks!!

Have you seen this, @trj2 ?

@NatalieGExum clouds too, apparently: pubs.acs.org/doi/full/10.10…

@trj2 Ugh, they are everywhere.

Microplastics in bottled water? Watch how challenging it is to communicate the health risks posed by bottled water. A good case study.

@Redkiraz @FabianSpuehler i'll mention it and see what they think at our next meeting.

@Redkiraz @FabianSpuehler we don't estimate incidence, we only report gene copies and Re estimates (which are trends in incidence, but not incidence directly). We also do not recalculate baseline twice a year. At the BAG, they also report the percent load. recalculating is an interesting idea for this

Dear @trj2 @FabianSpuehler -Does Eawag re-calculate the baseline every year using past year's data? -What is your formula for estimating (very approximately) the incidence, on basis of gene copies found in a wastewater plant? Thanks in advance🙏

@trj2 Could you post a link to the wastewater website?

@dominiksteiger Thank you for this. We see an unexpected high increase, we're looking to confirm the data. Good to see others report it as well.

@dominiksteiger and the Re estimate...

@dominiksteiger the BAG delay was due to our data delivery delay. We fixed the problems, all related to getting a new data pipeline up and running

@dominiksteiger this sometimes happens, where we see a huge spike one day, and it drops back down.

@dominiksteiger The Chur value is real. We extracted it multiple times, even with a different method, and measured it on ddPCR 3 times in duplicate. Maybe there is a single super shedder for that one day? Or maybe there is something about fate and transport in sewers that caused a spike?

@dominiksteiger @sci20210108 yes agree! unfortunately, there are so many dependencies, i'm not sure how that will be affected yet. but we keep it as long as we can.
