As of August 8th, Chad has registered a total of 320 cholera cases and 15 deaths. A rapid escalation was observed over a 72-hour period, with 52 new contaminations emerging. The national case fatality rate has climbed to an alarming 4.7%, significantly exceeding the 1% benchmark typically associated with well-managed outbreaks. The epidemic currently impacts three provinces: Hadjer-Lamis, Lac, and the capital city of N’Djamena. Across these regions, cases have been identified in 58 distinct villages and neighborhoods spanning twelve active health zones, underscoring the widespread nature of this humanitarian Sahel challenge.

Hadjer-Lamis province continues to bear the brunt of the infection, reporting the highest number of patients. Within this province, the Karal district alone accounts for 168 cases and five deaths, resulting in a 3% fatality rate. However, a more critical picture emerges in N’Djamena. Despite fewer overall contaminations—92 in total—the capital has recorded eight patient fatalities. Its staggering 8.7% case fatality rate stands as the highest among all affected areas. In Lac province, particularly around the Kangalom district, the count stands at 60 cases and two deaths, with a lethality of 3.3%. Laboratory analyses further corroborate the active circulation of the disease; out of 48 cultures examined, a significant 27 (56%) tested positive.

Young patients disproportionately affected

A striking characteristic revealed by health data is the remarkably young median age of those infected, standing at just 10 years old. Furthermore, most patients present for treatment in a critical condition, requiring immediate medical intervention. Reports indicate that 84% suffer from moderate to severe dehydration, a dangerous complication directly linked to the most virulent forms of cholera. Nationally, the attack rate for this Chad cholera outbreak is estimated at 13.3 cases per 100,000 residents.

The primary public health response centers on an extensive vaccination campaign targeting vulnerable areas. By August 8th, a total of 143,367 individuals had received vaccinations, achieving 89.1% coverage of the designated target population. Despite these efforts, health teams face significant hurdles that facilitate disease transmission. These include inadequate access to clean drinking water, deficient sanitation infrastructure, widespread open defecation, high population density in certain communities, and frequent population movements. In Lac province specifically, communication challenges further impede crucial awareness campaigns, patient monitoring, and the effective organization of health interventions.

Officials strongly advise frequent handwashing with clean water and soap, consuming safe drinking water or water that has been boiled, and seeking immediate medical attention for any sudden onset of diarrhea. Cholera is an acute intestinal infection primarily spread through the consumption of contaminated water or food. Its severe manifestations lead to rapid dehydration, which can prove fatal if not treated promptly.
