Cholera: A resurgent, potentially deadly gut bacteria DW 08/19/2025
Briefly

Cholera infections have surged in Sudan, with over 65,000 cases reported, including approximately 32,000 in 2025 alone, leading to about 1,700 deaths. The ongoing conflict has severely disrupted access to safe water and healthcare systems crucial for cholera prevention. The World Health Organization highlighted a 13% global increase in cholera infections, impacting particularly vulnerable populations, including children under five. In Sudan's North Darfur, 25% of cases are found in this age group, with rapid dehydration becoming life-threatening due to their undeveloped immune systems. Cholera is caused by Vibrio cholerae bacteria, resulting in acute watery diarrhea.
"In Sudan, the conflict has severely disrupted access to safe water, sanitation, and healthcare—the very systems that prevent and contain cholera," wrote Joe English, an Emergency Communication Specialist at the United Nations Children's Fund (UNICEF).
"Children are especially vulnerable. Their immune systems are less developed, and the rapid dehydration caused by cholera can become life-threatening far more quickly in [their] young bodies," said English.
"Vibrio cholerae serotype O1 causes severe, dehydrating, watery diarrhea and can kill a patient within 24 hours," wrote David Sack, an expert in cholera.
