Black Cat Leads to Discovery of First Jeilongvirus in the U.S.

A Florida scientist's pet cat uncovers a new virus with potential cross-species infection risks.

Pepper, a cat in Gainesville, Florida, brought home a mouse carrying a previously unidentified jeilongvirus, now named Gainesville rodent jeilong virus 1 (GRJV1).
The virus is part of the paramyxovirus family, which includes pathogens like measles and mumps, and has shown the ability to infect human, primate, and rodent cells in laboratory tests.
GRJV1's ability to infect multiple species suggests it could potentially cause a spillover event, though the current risk to humans is considered low.
Researchers emphasize the importance of further studies to understand the virus's impact on animals and its potential presence in humans.
This discovery highlights the need for increased viral surveillance, especially in areas where humans and wildlife interact closely.
