Cholera

Cholera in Chad — composite national figure. Chad is facing three provincial episodes. The Ministry of Public Health and Prevention has now published a consolidated national situation report covering all three — 320 cases and 15 deaths as at 6-8 August 2026, a case fatality ratio of 4.7%, with 52 new cases in 72 hours across 58 villages and neighbourhoods in 12 active health response zones (relayed by UN OCHA) — but its cut-off predates the Ministry's 11 August provincial update, so the count shown here (377 cases, 15 deaths) instead sums the most recent figure available for each province. That national report breaks down as N'Djamena 92, Hadjer-Lamis 168 and Lac 60 cases, and 8, 5 and 2 deaths respectively, summing exactly to its own national totals — confirming that the Ministry itself composes the national count as the sum of its provinces. Hadjer-Lamis: the Karal health district, where the outbreak was confirmed on 13 June 2026 after detection of Vibrio cholerae O1, serotype Ogawa, stands at 168 cases and 5 deaths, a case fatality ratio of 3%, and remains the largest of the three foci; a ministerial circular dated 24 July 2026 states that the rapid response halted transmission in that episode, and the Ministry's 11 August update confirms no new data has been released for the province since. N'Djamena: a separate episode confirmed on 24 July 2026 after three suspected cases on 19 July in the Farcha neighbourhood (1st arrondissement), now covering nine neighbourhoods of the capital; the Ministry reports 96 cumulative cases and 8 deaths as at 11 August 2026, with 84 patients discharged recovered and 4 still hospitalised. Lac: declared on 8 August 2026 by the government's general delegate, with three active foci in island areas and at Ngorerom, in the Bol sub-prefecture; it is growing fastest of the three, reaching 113 cases and 2 deaths by 11 August, with 60 discharges and 52 patients still hospitalised. Situation report no. 029, cut-off 2-3 August 2026, recorded 212 recoveries nationally, with 5 of its 13 deaths occurring in the community, a median patient age of 10 years and close to 78% of patients reaching health facilities with moderate or severe dehydration, a sign of late presentation. The recovery count shown here is still that 2-3 August figure and understates the current total, as no recovery figure has been published for Karal since that episode closed.
