Dengue fever is spreading rapidly in Sudan, exacerbated by war-damaged infrastructure and stagnant water, leading to a severe health crisis.
KHARTOUM (Reuters) -Tens of thousands of Sudanese people have fallen victim to dengue fever and other diseases, Sudan's health minister said, as seasonal rains further test infrastructure and hospitals devastated by conflict.
As millions of people displaced by fighting return to their homes in Sudan while others continue to flee, the unusually high spread of diseases like dengue fever, cholera and malaria this year highlights the hidden costs of almost 30 months of war.
The conflict between Sudan's army and the paramilitary Rapid Support Forces has created the world's worst humanitarian crisis and spread famine, and has shown no signs of slowing - although the army has recaptured the capital Khartoum and other parts of the country.
Exhausted patients lie under mosquito nets in packed wards in Omdurman Hospital as they receive intravenous paracetamol drips, the main treatment for the disease which can be fatal on second exposure.
TENS OF THOUSANDS OF CASES
More than 2,000 cases of dengue fever were recorded nationwide over the week ending on Tuesday, mostly in Khartoum, according to the Ministry of Health, but the minister said the real numbers falling ill were likely much higher.
"80% of cases are minor and do not reach the hospital so we expect it to be tens of thousands of cases in the past period across Sudan," Haitham Mohamed Ibrahim told Reuters.
The mosquitoes that carry the disease thrive in stagnant water including inside homes. In Sudan, the rainy season has left pools of standing water across the country, while people have resorted to storing water at home after fighting in the capital has destroyed power grids and running water systems.
"The government isn't doing anything, the rainwater is stagnant in the street, trash is everywhere and the mosquitoes are growing more and more each day," said Salaheldin Altayib, a 65-year-old trader in Omdurman who said he and two other family members had fallen ill from dengue fever.
HIGH PREVALENCE OF MOSQUITOES
The minister said systems to spray insecticides had been damaged.
"The continuation of war for more than two years has had a direct impact on the environment, health, the build up of trash and waste, the destruction of water sources, has created a new reality ... of the high prevalence of mosquitoes," he said.
While efforts to vaccinate the population and treat water have resulted in a relatively controlled cholera outbreak in the capital, the Darfur region has seen the disease peak, with 12,739 cases over the past four months, the World Health Organization said on Tuesday.
Some 61% are in the town of Tawila, which has sheltered hundreds of thousands of people fleeing the fighting in and around the city of al-Fashir, the current epicentre of the violence.
Efforts are also under way to vaccinate people there, the WHO said.
Global aid cuts have hampered the ability to treat these diseases, Ibrahim said. Some $39 million is needed to treat the several concurrent epidemics, he said.
Current U.N. data shows Sudan's donor-dependent healthcare appears to be less than a third funded.

Sudan is experiencing a high spread of diseases including dengue fever, cholera, and malaria, exacerbated by the ongoing conflict and seasonal rains.
More than 2,000 cases of dengue fever were recorded nationwide over a week, primarily in Khartoum, with estimates suggesting tens of thousands of cases overall.
The rainy season has created stagnant water pools across Sudan, which are ideal breeding grounds for the mosquitoes that transmit dengue fever.
Current U.N. data indicates that Sudan's donor-dependent healthcare system is less than a third funded, hampering efforts to treat concurrent epidemics.
Efforts to vaccinate the population and treat water have helped control cholera outbreaks in the capital, but the Darfur region has seen a significant peak in cases.
