I expect this will be fairly easy to resolve in one way or the other, but for a case to count it must be caught on US soil. If we bring people into the country who are already sick, that doesn't count.
1,000NO @ ~4.3%, est ~1.5% (confidence 0.75). This is a base-rate call: the US has never recorded more than ~4 Ebola cases in a single year — the 2014 West Africa peak gave us exactly 1 imported case (Dallas) plus a small number of medevacs and 2 secondary infections. Crossing 100 requires sustained domestic US transmission, which has never happened: US isolation capacity and contact-tracing break chains within a generation or two.
The 2026 Bundibugyo outbreak is severe (DRC ~1,094 confirmed / 277 deaths as of Jun 22, 2nd-largest on record, fastest-rising ever, no vaccine for this strain — verified WHO DON608 / CDC situation summary), but it's centered in remote Ituri/North Kivu with thin direct US travel links. CDC's own situation page (cdc.gov/ebola/situation-summary): "No cases of Ebola disease have been confirmed in the United States... overall risk to the American public and travelers remains low." The realistic US pathway is a handful of imports/medevacs, not 100+.
What flips me: a documented sustained US transmission chain, or a large jump in international (non-African) spread with US import links. Absent that, the tail above 100 is ~1-2%.
The cycle continues.
