Recent reports
Cholera — Gamboma district (Nkéni‑Alima department), Republic of the Congo
Local health teams detected and laboratory‑confirmed cholera cases in Gamboma in early October 2026; rapid diagnostic tests were positive and samples were confirmed at a Brazzaville laboratory, and at least one death was reported among the household cluster described in the field report. UNICEF field report (5 Oct 2026). The UNICEF account says immediate treatment and isolation measures were put in place, that health teams used rapid tests and PPE, and that no recent additional cases were detected in Gamboma at the time of the report but that risk remains in neighbouring areas. UNICEF (5 Oct 2026). Why it matters to travellers: cholera is transmitted by contaminated food or water; travellers visiting rural or riverine communities where safe water and sanitation are limited could be exposed. Public sources note that for most travellers the risk is low if they have access to safe food and water, and that cholera vaccination is usually reserved for people at higher occupational or exposure risk (for example, humanitarian workers) — see practical guidance on prevention and the limited role of routine vaccination.

Ebola (Bundibugyo) — ongoing outbreak in neighbouring Democratic Republic of the Congo; cross‑border risk
An expansive outbreak of Ebola disease caused by Bundibugyo virus continues in the Democratic Republic of the Congo (DRC); WHO reported thousands of confirmed cases and a high number of deaths in its 26 August 2026 Disease Outbreak News and advised that the risk to countries sharing land borders with the DRC is high because of population mobility. WHO Disease Outbreak News (26 Aug 2026). WHO also reports that entry and exit screening and surveillance measures are in place at airports, ports and official land border crossings in the affected area and stresses the importance of cross‑border collaboration and preparedness. WHO (26 Aug 2026). As of the WHO report, no confirmed Bundibugyo cases were reported from the Republic of the Congo; however, the geographic expansion in the DRC and cross‑border movements have prompted heightened surveillance across the region. WHO. Several neighbouring and regional authorities have publicly described active traveller screening and contact‑tracing measures after imported cases were detected elsewhere in the region (example: Kenya’s October 2026 screening and tracing following an imported case). Pulse Kenya (6 Oct 2026). Why it matters to travellers: travellers who transit to or from the DRC or who plan travel to border areas should expect enhanced port‑health checks in some countries, should follow local health authority instructions, and should seek medical advice promptly for fever or other compatible symptoms; WHO currently advises against general travel restrictions but recommends strengthened surveillance and cross‑border preparedness. WHO (26 Aug 2026).
