Drinking-water quality is a rising concern in the United States (US), emphasizing the need to broadly assess exposures and potential health effects at the point-of-use. Drinking-water exposures to per- and poly-fluoroalkyl substances (PFAS) are a national concern, however, there is limited information on PFAS in residential tapwater at the point-of-use, especially from private-wells. We conducted a national reconnaissance to compare human PFAS exposures in unregulated private-well and regulated public-supply tapwater.

Article Synopsis
  • The study examined 62 new cases and 18 previously published reports of Dracunculus infections in dogs and cats across North America to better understand the distribution and characteristics of this parasite.
  • Infected dogs were primarily aged between 7 months and 19 years, with most cases involving single worms typically found in the legs, but those also appeared in other body areas; infections did not occur in toy breed dogs.
  • Three new individual cat cases were detected in the southern U.S., and most infections in both species occurred from late winter to early spring; genetic analysis identified the nematode species primarily as D. insignis, linked to raccoons.
