TOPIC BRIEFING

自然災害・気候/感染症・バイオセキュリティ

自然災害・気候と越境感染症・バイオセキュリティを、異なる二つの節で毎日点検する。警報、予測、実測、確認された影響を分ける。

エボラと麻疹の継続、アジア・太平洋の暴風雨、インドの干ばつを区別して追う。

毎日点検するシナリオ

これらは併存し得る経路です。期限と成立条件を固定した個別予測以外に確率を付けません。

争いあり · Weeks to months after the 26 Sep 2026 information cutoff

影響の収束・復旧

Recovery is observable in Nepal routine immunization and cholera vaccination, but facility damage and household aid needs remain. The evidence is geographically bounded and does not show full restoration.

Event: · Evidence: src-who-nepal-floods, src-who-nepal-vaccination

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Verify repaired/reopened facilities, district-level service continuity and unmet household needs.

支持あり · Days to weeks after cutoff

災害影響の継続

Persistent disruption remains plausible and locally evidenced: three health posts destroyed, one hospital partly damaged, two access routes/facilities affected and around 10,000 households needing aid. These are WHO reported impacts from the August floods, not a new disaster.

Event: · Evidence: src-who-nepal-floods

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Track service access and health facility restoration after rains; distinguish current conditions from cumulative damage.

未確認 · Days to weeks after cutoff

複合災害の拡大

Compound hazard scenario remains unknown. Hurricane Polo has a high-intensity Baja approach forecast but no verified landfall or impacts by cutoff; separate hazard reports are only selectively reviewed.

Event: · Evidence: src-nhc-polo-advisory24, src-nhc-polo-discussion24

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Use next NHC advisories and observed landfall/rainfall, then confirm secondary hazards and impacts with local authorities.

争いあり · Weeks to months after cutoff

拡大抑制

Containment is mixed across distinct outbreaks. WHO declared Uganda’s outbreak over after 42 case-free days, but DRC remains an active Bundibugyo outbreak with a reported 48-zone activity footprint in the preceding 21 days.

Event: evt-20260927-who-drc-ebola-update · Evidence: ev-20260927-who-drc-ebola-update, src-who-uganda-end

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Review WHO updates using their data cut-off, new cases by zone and cross-border surveillance; keep Uganda and DRC status separate.

支持あり · Weeks to months after cutoff

地域内拡大

Regional transmission concern is supported by the DRC footprint and WHO’s 14 Aug assessment of high risk in land-bordering countries, but that assessment is dated and is not a current reassessment. WHO advises against travel/trade restrictions.

Event: evt-20260927-who-drc-ebola-update · Evidence: ev-20260927-who-drc-ebola-update, src-who-ebola-risk-v4

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Check an updated WHO risk assessment, spread beyond DRC, and verified border/public-health measures.

未確認 · Weeks to months after cutoff

国際的な拡大

International spread is not established by this evidence. DRC’s substantial domestic outbreak and regional risk tiers do not demonstrate sustained transmission outside the country; no cross-border transmission event is added here.

Event: evt-20260927-who-drc-ebola-update · Evidence: ev-20260927-who-drc-ebola-update

PROBABILITY · UNESTIMATED

数値確率は未推定。六つのScenarioは並行して成立し得る災害・感染症経路で、完全な標本空間と判定規則がなく、証拠・報告範囲にも未確認が残る。

次の観測: Require a confirmed exported case with transmission chain outside DRC, or WHO evidence of sustained cross-border transmission.
