Early analyses of COVID‑19 case numbers showed that viral
spread strongly correlated with population movement from initial outbreak
regions. Imagine a SARS‑CoV‑2–like
virus emerges, but rapid international travel restrictions and large‑scale
movement controls are implemented before widespread dissemination occurs. The
virus retains the same biological transmissibility.

Given these conditions, what outcome is most likely over
time?
