Global Strategies to Protect Seals and Sea Lions from Avian Influenza

Katherine E Kerlin — March 19, 2026 - 9:02am

When the H5N1 highly pathogenic avian influenza virus was discovered on a poultry farm in Asia in 1996, there was little indication that it would become so widespread and so destructive.

The Hunt Narrows for Ebolavirus Hosts

Katherine E Kerlin — January 15, 2025 - 9:30am

Bats are widely recognized as the primary hosts of filoviruses, such as Ebola, yet the specific host species of ebolaviruses are not definitively known. In a study led by the University of California, Davis, and the Albert Einstein College of Medicine (Einstein), scientists have developed a new tool to narrow down potential host species of filoviruses and better prioritize wildlife surveillance. The research is part of global efforts to prevent viral spillover between animals and humans.
