We are tracking mutations of #RSV in #wastewater: genspectrum.org/swiss-wastew.... Why this matters and why you should re-tweet for visibility (a 🧵).

"New infections in children were associated with preceding household detection of the same pathogen in soil (Odds ratio: 8.8, 95% confidence interval: 3.3, 23) and on child hands (Odds ratio: 5.0, 95% confidence interval 1.1, 17)."
New pre-print on infant first infections with enteric pathogens! 85% of pathogens detected in infants are also in animals living nearby, using longitudinal sampling we find child hand contact with soil contaminated with animal feces is a primary transmission pathway! www.medrxiv.org/content/10.1...
Zoonotic and environmental sources of infant enteric pathogen infections identified with longitudinal sampling
Enteric pathogen infections in young children can result in diarrhea, malnutrition, and developmental impairments. Many enteric pathogens that infect young children can be zoonotic, yet the exposure r...

#Wastewater-based monitoring for #PublicHealth holds a lot of promise, but an outstanding challenge is to understand what public health relevant metrics can be derived, and how we translate data into impact. See our Viewpoint on #AMR #AntimicrobialResistance in #EST 👇
Our new Viewpoint article led by Sheena Conforti & Amy Pruden originating from the #EDAR7 conference is now out in Environmental Science & Technology (@acs.org)

If you're measuring #Legionella in a water system using qPCR, how do you relate your value to culture? We suggest a conservative 1:1 assumption! Unless you know more about your system, this seems accurate based on a systematic review. Led by Emile Sylvestre: journals.plos.org/water/articl...

From the #Swiss #Wastewater, signs of #SARS-CoV-2 receding, while both #influenza A and B continue an upward rise. #RSV looks to be staying stable, could be evidence that it has peaked. From: wise.ethz.ch

Everything is everywhere all at once: #Influenza A, Influenza B, and #RSV are all increasing in #Zurich wastewater, while #SARS-CoV-2 still circulates. From wise.ethz.ch.
