The Sudanese Medical Syndicate warned on Monday of the deterioration of the health situation in the country after the spread described as catastrophic dengue fever, while battles continued between the Sudanese army and the Rapid Support Forces in the capital's three cities.

The Doctors' Syndicate confirmed the worsening of the disease and the overcrowding of hospitals, especially in the state of Gedaref (southeast) with patients, as well as homes, where it is impossible to provide beds for all the injured.

The syndicate called for the need to work on providing logistical, technical and medical resources to confront this epidemic before an unavoidable medical disaster occurs.

Health services in Sudan suffer from a shortage of resources, supplies and services, especially with a large number of health authorities out of service due to the fighting.

More than 70 per cent of medical facilities in conflict zones have ceased to function. Some 100 hospitals were out of service in Khartoum and Darfur states.

The World Health Organization confirmed that 56 health care facilities in Sudan had been attacked.

The United Nations Children's Fund (UNICEF) said 13.5 million Sudanese children were in urgent need of aid, water, treatment, nutrition and protection.

UNICEF estimated the cost of needs to continue child health assistance at more than $837 million.
