His account was supported by aid workers from U.N.F.P.A., CARE, International Medical Corps, Doctors Without Borders and Save the Children, who told The New York Times that the crisis affecting pregnant women is emblematic of the collapse of the public health system throughout Sudan since the fighting started.

“This is only going to get worse,” said Adive Joseph Ege Seriki, the global adviser for sexual health and reproductive health at International Medical Corps, which has been working to train health care workers across Sudan.

The dire maternal health situation also has consequences for babies born prematurely. “Preterm babies are at high risk of developing lifelong defects,’’ he said, including intellectual disabilities, cerebral palsy, and hearing and visual impairments.

Even before the current conflict, Sudan had a fragile health system with inadequate infrastructure and equipment, a shortage of skilled health professionals and a limited supply chain. According to the U.N., Sudan’s maternal mortality rate was about 270 deaths per 100,000 live births, compared to 21 per 100,000 in the United States.
