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.

The research is part of global efforts to prevent viral spillover between animals and humans.
