David Quammen's essay in The New York Times today closes with this paragraph. It's both a scientific falsehood, and an incredibly dangerous narrative. If you're willing to give me five minutes of your time, I'd like to explain why.
The Ebola virus doesn’t need to spill back. It abides in its reservoir host, and awaits its next opportunity. A virus can’t climb out of a bat or a monkey and fly off in search of human prey. It can only spill over. If humans left the reservoir host alone — not hunting it, not capturing it, not eating it, not exporting it live, not disturbing its forest habitat — the virus wouldn’t re-emerge in humans. It would remain where it is, harming no one. But of course that’s not what happens. And when viruses spill, they often spill into us, because the human population is such a big, busy target.

Thrilled to see this published today! Truly special because we made the initial discovery >15 yrs ago! We found two copies of a human gene called BC200 embedded in a human poxvirus. BC200 blurs the line between gene & transposon—both functional & mutagenic! www.science.org/doi/10.1126/... 🧵1/n

Direct cell-to-cell transmission of retrotransposons
Retrotransposons can infect neighboring cells using a mechanism that relies on a small fusogen-like protein rather than on the envelope protein that is typically required for infection.

Top: Barrier-resolved framework for OrV host competence across Caenorhabditis species. Conceptual summary of the seven barriers evaluated in this study and the expected empirical signature if each barrier limits OrV host competence. The framework distinguishes early susceptibility/establishment, within-host replication kinetics, RNA2:RNA1 genome-segment balance, luminal localization consistent with egress or viral material accumulation, functional transmission, virulence, and evolutionary persistence under serial passage. Bottom: Representative smiFISH images of OrV infection in alternative host species, showing C. elegans and the alternative host species at 24 hours post-inoculation (hpi).
