Ebola — Moroni (Prince Saïd Ibrahim International Airport), Ngazidja (preparedness measures)
On 24 August 2026 the Comoros Ministry of Health reported a WHO‑supported mission to inspect and evaluate surveillance, infection control and arrival‑zone measures at Moroni’s Prince Saïd Ibrahim International Airport as part of efforts to strengthen early detection and rapid response against a possible importation of Ebola virus disease. Ministry of Health report, 24 Aug 2026. This is a preparedness / screening‑capacity activity rather than a report of local Ebola transmission; travellers should note that authorities checked arrival‑area systems and engaged Red Crescent volunteers to support point‑of‑entry measures.

Cholera — anticipatory planning by Comoros Red Crescent / IFRC (national-level preparedness)
In September 2026 the IFRC / Anticipation Hub published a Simplified Early Action Protocol (sEAP) describing how the Comoros Red Crescent will act ahead of a predicted cholera event; the Anticipation Hub posting is dated 15 September 2026. Anticipation Hub: Simplified EAP — Comoros | Cholera, 15 Sep 2026. The IFRC appeals/operations listing also shows a Comoros cholera sEAP (MDRKM015) and related DREF planning in early September 2026. IFRC appeals listing (Comoros Cholera sEAP, 01 Sep 2026). These materials describe anticipatory stock, volunteer mobilization and community‑based actions to reduce transmission risk; travellers should recognise that heightened local preparedness can follow seasonal and regional warnings but does not by itself confirm widespread active transmission.
Cholera context — national case history and recent reporting
WHO’s Weekly Epidemiological Record (issue dated 25 September 2026) presents the 2025 cholera annual review and notes that Comoros reported a large outbreak in 2024 (10,692 cases) and subsequently submitted a zero report for 2025, illustrating both the country’s recent major outbreak and its later absence of reported cases. WHO WER (Cholera Annual Report, 2025), 25 Sep 2026. That WHO report is background evidence that cholera has been a recent, serious event in Comoros; the IFRC/Anticipation Hub documents above describe actions taken in 2026 to prepare should transmission recur.
Summary: the principal outbreak‑related items verified in the reporting window (29 Jul–27 Oct 2026) are domestic preparedness and anticipatory response actions: (1) Comoros Ministry of Health evaluation of airport surveillance and arrival‑area measures for Ebola risk (24 Aug 2026), and (2) Red Cross / IFRC anticipatory cholera planning and a Simplified Early Action Protocol in September 2026. WHO’s Sept 2026 Weekly Epidemiological Record provides context on the country’s recent cholera history.

What this means for travellers: these items describe preparedness and anticipatory operations rather than confirmed, widespread new transmission inside the Comoros during the reporting window. Travellers should follow routine pre‑travel health precautions (food and water hygiene, malaria prevention where recommended, and up‑to‑date routine immunizations) and check current official travel‑health advice before departure. For entry‑screening or point‑of‑entry procedures likely to affect travellers, consult the Comoros Ministry of Health and your national travel‑health authority shortly before travel.
