Over all trends are consistent with #15DayTrends (based on sequences uploaded in the public databases)

XBB.1.5 is still at the top; XBB.1.9.1 makes an entry

Expected XBB.1.5.13 and XBB.1.16 to feature in the CDC dashboard variant line up today..

Can you effectively manage wastewater in your locality?

Check out these snippets from the comic book “Neera, Jalaj and the Case of Untreated Waste”, that tell us how we can achieve sustainable #wastemanagement ...🧵
10-year-old Jalaj was curious about how efficiently waste can be used.

He kept thinking about the technology that helped #recycle and reuse it. Jalaj wondered how he could replicate the system in his own #environment.
First, Jalaj tackled the solid waste by building a toilet with a twin leach pit, with the help of his friends. A twin leach pit is a toilet that can manage faecal waste locally.

As we already know from our first post about Munich’s sewage system it was created over 200 years ago and only happened after a big #epidemic catastrophe in which Queen Therese of Bavaria died. 1900 around 78% of the 480.000 citizens of #Munich were connected to the #sewer.
1/7 The picture is made up of a...
During that time, all the #wastewater was just added to the Isar river in the north of Munich. The city’s #sewagesystem was built with a small decline to the north. Therefore, it didn’t need a lot of pumps or other technical equipment to channel the #water in that
direction. #People that lived down the #river, i.e., in #Freising and #Landshut protested about all the dirt in the water and its smell. In 1926, the first #wastewater treatment plant “Gut #Großlappen” was built. It is in the north of Munich, close to the #Allianzarena.

Important to note that case data is hugely undercounting this surge. COVID testing has slowed and shifted to unreported antigen tests. Plots like below can mislead because the current surge looks so much lower than January. But #wastewater data reveals the true levels. (1/4)
In this example from San Francisco, the concentration of SARS-CoV-2 in wastewater is in blue, and publicly reported cases in red. The red curve might lead you to conclude cases are much lower than in January, but the wastewater values are as high or *higher* than back then! (2/4)
Testing practices changed drastically during this time period, but people still go to the bathroom. Plotting positivity also supports the conclusion that wastewater is giving the more consistent picture of disease levels - there is a close match between ww and positivity. (3/4)

Current research on microplastics is the stuff of nightmares-

They’re dangerous, they’re spread through our food, they're in the air... they’re everywhere

Thread 1/x
#health #ClimateCrisis #PlasticPollution #food
Much of the research is trapped behind paywalls, and only reported on in a limited, fragmented pattern

-like so much else when large corporations cause environmental damage and impose widespread health impacts on the public

#health #ClimateCrisis #PlasticPollution #food
The growing risks of microplastics are a direct function of an ongoing push by the same sociopathic corporations that are driving the climate crisis

-Spike L452R* and L452Q is prevalent in #Wastewater samples (will update in a separate thread)

📊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

When it comes to #wastewater (ww) detection, all COVID-19 variants — and more broadly, all respiratory viruses, are not created equal. 🧵
Going forward, we need combined approaches to track all sorts of viruses & microbes that threaten our health & our economies: air samplers, ww, and yes: direct samples from people, too (saliva, nasal swabs) & even animals #OneHealth. 2/
Importantly, however, I cannot stress enough the need to look beyond the pure technology driven solutions. It’s not just genome sequencing machines, library prep, read QC, 🧬 consensus assembly & phylogenetics. Community engagement & “buy-in” from general public is PIVOTAL. 3/

Meanwhile in #France,
"the peak of this second wave is over"

(according to the President in his Adress to the Nation):
Wait... "the peak is over" doesn´t mean "it´s back to normal"!

Confinement will only fall on December 15,
if there´s less than 5.000 new cases a day.
(today it´s ~9.000).

France is disappointed.🙁

Although they certainly can make it happen.
Meanwhile in #Switzerland:
(excess mortality of the second wave is significant)

Good news: fastest decrease in infections happens in the worst hit areas now.

For a virus that presents "few to no symptoms" for the majority, "U.S. Orders Up to 600 Million Doses of #Pfizer, BioNTech Covid #Vaccine" (Bloomberg).…

As #COVID19 cases are found to spread, #Melbourne (city of ~5 million) tries to contain them by going into #Lockdown.
(The interview features the idea of a dedicated #Quarantine building - that would actually help, I guess)...
"People acting as if the pandemic was over was 'not the answer, it is part of the problem' ".

"The virus had leaked from postcodes already under the stay-at-home orders to other parts of #Melbourne."
(and beyond, it is feared).
Due to #Melbourne's outbreak, neighbouring South Australia is about to completely close it's borders to #Victoria.

(Nearly) no exceptions. And those essential few who are allowed in, will have to wear facemasks the entire time...

Vorpommern-Greifswald district (where rejections of #Gütersloh residents took place, yesterday)
has specific rules:
"Those who return from international risk areas (out of Germany) or whose Corona-Warning App has alerted them, need to report to authorites" Image
In fact, Mecklenburg-Vorpommern's Corona-ordinance really prohibits entry of people from international risk areas AND german risk areas as well.
It's just not prominently featured on their websites.

(Overlooked that myself, hence deleted earlier tweet)… Image
People from #Gütersloh district may have to scrap all their holiday plans anyway...

An official #Lockdown is just being announced for the entire district.

This 2019 report by the National Statistical Office presents the results of the survey Drinking Water, Sanitation, Hygiene & Housing Condition in India. The last such survey was taken in 2012 by the National Sample Survey…
Its objective was to understand the conditions necessary for a household to live a decent and #healthy life, and to develop indicators for such an assessment. For this purpose, the NSS examined the living conditions of households across India.
Information was collected on a range of parameters, including: the type, condition, and ‘tenurial status’ of the dwelling/residential unit, the drainage system of the unit, system of disposal of household wastewater and garbage, and problems of flies and mosquitoes.
