Grounds assessments

activeCalifornia CDPH will issue a formal mpox Clade I cluster alert or public health emergency with ≥10 confirmed cases by 2026-07-19, based on CDPH messaging shift to statewide surge framing within 72h of the Apr 16 SF index case.60%activeA locally-acquired Clade I mpox transmission chain (≥2 epidemiologically linked cases without African travel history) will be confirmed in North America within 90 days of the San Francisco Clade I detection (Apr 19 2026).40%activePakistan (Khairpur/Sindh) mpox cases will be genomically confirmed as Clade Ib by WHO DON or Pakistan MoH by June 2026, representing the third non-African Clade Ib community transmission geography after Spain (Dec 2025) and Singapore (Apr 2026), based on infant mortality in Khairpur district (7 infants dead/positive, Apr 2026) and demographic severity patterns consistent with Clade Ib rather than Clade IIb.40%activeAt least one confirmed mpox Clade Ib case with travel linkage to Singapore will be detected in Japan, South Korea, or Australia by October 2026, given Singapore's confirmed local Clade Ib transmission (2 cases, CDA Apr 4 2026) and Singapore's role as the primary aviation hub for East Asia–Pacific travel.50%resolvedAt least one confirmed mpox Clade IIb case linked to Singapore will be detected in Japan, South Korea, or Australia by October 2026, given Singapore's confirmation of local Clade IIb transmission (Apr 14 2026) and its role as the primary aviation hub for East Asia–Pacific travel.50%resolvedMpox clade Ib will be confirmed in at least 2 East African countries outside the DRC by April 2026.90%activeCalifornia will confirm at least 2 additional Clade I mpox cases (beyond the San Francisco Apr 16 index) within 60 days of Apr 20 2026, with at least one in Los Angeles County or adjacent counties — indicating multi-focus Clade I circulation rather than isolated importation.60%activeWHO will issue a Disease Outbreak News (DON) specifically addressing Clade Ib community transmission outside Africa (Spain Dec 2025, Singapore Apr 2026, Pakistan unconfirmed Apr 2026) as a distinct non-African Clade Ib spread pattern by June 30, 2026, given that the existing global PHEIC DONs have not yet characterized the non-African Ib pattern as a separate epidemiological entity.50%activeAt least one confirmed mpox Clade Ib case imported to the US will be significantly delayed in diagnosis (>7 days from symptom onset to laboratory confirmation) or go initially undetected due to CDC diagnostic capacity gaps, by October 2026, given that CDC paused mpox and rabies diagnostic testing capability (Apr 1–2 2026) during an active global PHEIC with confirmed Clade Ib community transmission outside Africa.50%
