Types de catastrophes

A significant increase in dengue cases was observed in the last three weeks of epidemiological reporting (Weeks 47,48,49) in the country and this was further confirmed on the 18th December during the Health Cluster meeting, with 22,003 cases and 60 deaths reported. Children below five years old are 11% of the total caseload and 30% of the total death cases. Dengue outbreaks have affected 174 of 333 total districts (54%) in 22 of 23 governorates of the country. The highest governorates with suspected dengue cases are from Hodeiadah, Taiz, Aden, Hajja and Lahj and death cases reported from Hudaidah, Aden, Hajja, Lahj, Shabwa, Marib and Rayma. Most reported cases are concentrated in urban areas. The number of affected governorates is likely to increase due to the collapse of the health system in Yemen, the poor water and hygiene condition in the most affected areas, additionally due to the ongoing complex and protracted conflict, with limited access to humanitarian support to the most vulnerable and affected populations.
