## Executive Summary
A deadly tapeworm linked to severe liver disease is now found in Washington coyotes, signaling its spread across the Pacific Northwest.

## Intelligence Brief
The parasite, described as a deadly “fox tapeworm” and a rare dangerous parasite, has been detected in Washington state coyotes, marking its presence in West Coast wildlife. Researchers report it is linked to severe liver disease and is present in about one in three coyotes in the Pacific Northwest. Coverage emphasizes the emerging health risk to both animals and humans.


ScienceDaily, The Independent, The Times of India and Yahoo highlight the spread across America and the first West Coast detection, while Fox News focuses on the lethal disease connection. A‑Z Animals notes the 1 in 3 prevalence figure. Future reporting will monitor whether the parasite appears in additional wildlife species, potential human cases noted by The Times of India, and related livestock concerns such as the return of New World screwworm in Texas, as reported by AOL.com.


Researchers are expected to update on geographic expansion and health advisories.
