01
The current analyst view of this scope, at increasing levels of depth.
H5N1 semen-transmission hypothesis approaches Apr 28 resolution with no confirming data; Cambodia YTD at 4 cases; connector coverage impaired.
Five active hypotheses span dairy cattle semen transmission, Cambodia case trajectory, Nepal-India human spillover, and Pacific pinniped expansion. This cycle's evidence is limited to vaccine research publications (rabies-vectored H5N1 vaccine, seasonal flu cross-protection) with no new operational case signals. The semen-mediated transmission hypothesis resolves Apr 28 — no confirmation or refutation has appeared in the available evidence window.
02
Open assessments being tracked inside this scope, ordered for fast review.
USDA or peer-reviewed publication will document within-herd H5N1 transmission in US dairy cattle attributable to semen-route exposure (confirmed via epidemiological linkage or experimental inoculation) within 120 days of the Apr 21 2026 tri-state semen RNA announcement.
