Biobot World Cup deep dive.

In 2026, wastewater continues to be a top predictor of infections, emergency department (ED) visits, and other outcomes. Here, they note a .88 correlation with ED visits, which is as close to perfect as it gets in science.

A study in Nature Communications shows that wastewater from Swedish hospitals favors antibiotic-resistant E. coli, unlike municipal wastewater. The study identifies the antibiotics ciprofloxacin and cefotaxime as key drivers. go.nature.com/4z1xqlx #microsky 🧪
This is figure 3, which shows enrichment of antibiotic-resistant E. coli in hospital sewer biofilms from wastewater.

“COVID in wastewater had started to decrease across the United States from the late summer wave, but now COVID is increasing again without the usual lull seen after a wave. Many states in the West, South, and Northeast have had high levels of SARS-CoV-2 in wastewater for over a month.”

Coleman, an evangelical Christian and Republican, believes Abbott was protecting an industry push to spread treated drilling and fracking wastewater on farms.

“We can’t get no help from the state level,” he said.

NSW Health has paused wastewater reporting. They are updating sampling, lab processing, and analysis methods. This major overhaul strongly indicates they are preparing to integrate with the upcoming ACDC National Wastewater Surveillance Program rollout.

Source: www.cdc.gov.au/diseases/sur...
An excerpt from the NSW Respiratory Surveillance Report focusing on the "COVID-19 Wastewater Surveillance Program". The text states that wastewater surveillance data is not being reported for the current week. It explains that this pause is due to ongoing changes being implemented for sampling, laboratory processing, and data analysis methods. The notice concludes by stating that reporting will resume once these revised methods are fully established and a sufficient amount of data has been collected.

New Zealand national COVID-19 trends from April 2025 to October 2026, comparing SARS-CoV-2 wastewater levels (green) with reported COVID-19 cases (blue). - Wastewater: Peaks around May 2025 (5.3 million genome copies per person per day) and February 2026 (6.2 million). - Reported cases: Highest around June 2025 (150 cases per day), with another peak in February 2026 (around 115). - Mid-2026: Both indicators generally decline, with smaller fluctuations. - October 2026: Wastewater levels and reported cases remain relatively low, with a slight uptick at the end. - Both indicators show similar overall trends, although peaks differ in timing and size. New Zealand wastewater variant analysis showing weekly percentages of SARS-CoV-2 variants from May 2025 to October 2026. - NB.1.8.1 (light turquoise): Dominant through much of 2025 and 2026, but declining in recent months. - XFG (blue): Circulated throughout the period, with fluctuating prevalence. - BA.3.2 (yellow): Rose sharply during April–June 2026, reaching around 60% in some weeks before declining. - PQ.16.1.1 (pink): Emerged in May 2026 and increased significantly by September–October. - JN.1 (purple): Increased during August–September 2026. - October 2026: PQ.16.1.1 and NB.1.8.1 account for the largest shares, with smaller contributions from XFG, JN.1 and other variants. - Each stacked bar represents the percentage of variants detected in wastewater for one week.

It’s Wastewater Wednesday! How are COVID levels? We’re using two sources to help us keep track of the country and our state of Oregon.

Thank you to @michael-hoerger.bsky.social for the map and graph, and OHA for continuing to track data coming from our wastewater treatment centers!
Two screenshots against a photo of red pomegranate seeds. The first is a map of the US showing COVID transmission, with states colored light blue to berry pink depending on severity. Lane County and the majority of counties in Oregon are berry pink which indicates very high transmission. Text notes that this data was last updated on October 24. The second screenshot is text that reads, “94% of Oregon community wastewater treatment centers were positive for SARS-CoV-2 on the most recent sample.”

Wastewater treatment is essential to the health of our communities. That’s why I delivered funding for the city of Lovington to make much needed upgrades to their plant!
