Conflict Escalation in Yemen – Situation Report #6 (Reporting period: 27 September – 2 October 2026 | Issued: 4 October 2026)

Country: Yemen Sources: Health Cluster, World Health Organization Please refer to the attached file. Highlights Conflict casualties • More than 5, 000 casualties, and the toll is climbing. 685 new casualties in six days, 114 a day against 101 in the previous period. The cumulative total since 6 August is 5, 166 casualties with 959 deaths (CFR 18. 6%). • Taiz has become the heaviest front. Daily casualties rose from 8 to 109 within the week as fighting moved into Taiz city. • The conflict is spreading. First casualty reports came from Hadramout and Al-Jawf, while Lahj and Marib remain severe. Access and protection of health care • The golden hour is being lost for want of front-line trauma stabilization points. Tier 1 Trauma Stabilization Points (TSP) are the biggest gap in the response. Six of the 20 planned TSPs have no partner support, so the wounded are not stabilized and in surgery within the first hour after injury. Funding is needed now to deploy skilled personnel, ambulances and surgical supplies closer to the front lines. • The front lines are hard to reach and harder to see. Communication blackouts and protection risks block real-time data from both sides, so reported figures are a minimum and reported attacks on health care are severely difficult to verify. Displacement • Almost 200, 000 people were displaced. 29, 519 families in ten governorates, up 8% in five days, with two thirds of the increase in Lahj. • Displacement is reaching the eastern governorates and neighboring country. The consolidated report now counts 454 families in Hadramout, Al-Mahra and Shabwah, as opposed to 201 on 23 September. The Mukalla hub reports a further 429 families in Al-Abr (Hadramout Al-Wadi), which the consolidated report does not yet cover. Over 3, 600 people have crossed to Djibouti. Disease outbreaks • Cholera has tripled in three weeks. 647 suspected cases in week 39 against 217 in week 36, with 94% of recent cases in the five governorates (i. e. , Abyan, Lahj, Al-Dhale’e, Taiz and Aden) hosting most displaced families. The last four weeks account for 1, 892 of the 7, 871 cases and 11 of the 27 deaths reported this year, with 89% of rapid diagnostic tests positive. • Cholera has reached the eastern camps. The surveillance system records two culture-confirmed cases in Al-Abr (Hadramout) in the last four weeks, among 12 suspected cases reported by the Mukalla hub. Gharan camp, where two cases were identified, has not yet been reached by the rapid response team. • Measles is spreading through an immunity gap that displacement is widening. More than 22, 000 suspected cases and 128 deaths have been reported this year (to week 38), with a spike in Hadramout, where displaced families are now arriving. Fewer than half of children are vaccinated (45% for each dose, WHO/UNICEF 2023 estimate), against the 95% needed to stop transmission. WHO warns that conflict interrupts routine immunization and that overcrowding in camps increases the risk of infection, and malnourished children are at highest risk of death. WHO recommends a supplementary measles dose from six months of age for internally displaced populations. Vaccination should be paired with vitamin A. • A strong El Niño is set to make outbreaks worse. WHO’s global El Niño analysis places Yemen among the countries at high or very high risk, with the peak expected from October 2026 to March 2027 and hotter, drier conditions expected to fuel cholera, dengue and malaria. • Acute malnutrition among displaced children. Of 54 displaced children under five screened by International Medical Corps mobile teams, 9 had severe and 29 moderate acute malnutrition. At least five facilities have run out of ready-to-use therapeutic food and three of supplementary food.
