Zurich Covid infections estimated at 700 per 100,000 via wastewater data
Original: # Covid Schätzung Infektionsinzidenzen für Zürich aufgrund Kalibrierung der Abwasserprävalenzen Werdhölzli, Daten bis 4.
New estimates put Covid incidence in Zurich at around 700 per 100,000, based on calibrated wastewater prevalence data from the Werdhölzli treatment plant, with figures current to early October 2026. That works out to roughly one in 140 residents being infected each week. The numbers are circulating among Swiss public-health observers tracking the virus through sewage surveillance rather than official case counts.
Why now: Wastewater-based Covid estimates suggest a notable current infection wave in Zurich, prompting discussion about the true level of transmission.
