Comprehensive emergency obstetric and newborn care has been suspended in two hospitals, in Marib and Ras Al-Arah, because staff and operating capacities have been redirected to trauma care.

Note
Yemen’s renewed war is now a disease warning. WHO’s regional emergency director for the Eastern Mediterranean, Dr Annette Heinzelmann, briefed journalists in Geneva from Cairo on Tuesday: several lifesaving supply lines at WHO’s Aden warehouse, including trauma kits and essential medicines, are at zero stock; nine health facilities have been damaged or directly attacked, mostly near Taiz, Lahj and Hudaydah; and emergency obstetric and newborn care has been suspended at two hospitals in Marib and Ras Al-Arah as staff shift to the wounded. Health authorities in Aden count more than 4,481 casualties, including 830 deaths, since the renewed clashes in the southwest began on 6 August.
Cholera is already present, with about 7,800 suspected cases and 22 deaths this year, and WHO fears spread through crowded shelters with unsafe water; more than 22,000 measles cases have been identified. More than 180,000 people have been uprooted, OCHA says more than one in four screened children are acutely malnourished, and Djibouti is bracing for thousands more arrivals. Updated counts go to the HUD.
Why it matters
Eight hundred thirty dead since Aug 6, the WHO warehouse in Aden out of trauma kits, maternity wards turned into trauma bays, and cholera already circulating in camps without clean water. Only about sixty percent of facilities were fully working before the fighting resumed.
