European eels transmit a herpesvirus through bites, revealing another route for fish infections

Researchers from the University of Liège have found that a herpesvirus affecting European eels can spread through bites, challenging the view that fish viruses are transmitted only through water. The finding identifies another route for infection among eels and may help scientists better understand how disease spreads in aquatic populations. The research broadens knowledge of virus transmission beyond water acting as a carrier.
