Chad reported 320 cholera cases and 15 deaths as of August 8th. The period between August 6th and 8th alone saw 52 new contaminations. The national case fatality rate has now reached 4.7%, a figure significantly exceeding the 1% threshold typically considered manageable when the disease is effectively treated. Three provinces are currently grappling with the outbreak: Hadjer-Lamis, Lac, and the city of N’Djamena. In total, 58 villages and neighborhoods across twelve active health zones have reported cases.

Hadjer-Lamis province continues to bear the highest burden of infections. Within this region, the Karal district alone accounts for 168 cases and five deaths, resulting in a 3% fatality rate. The situation in N’Djamena presents a different, yet equally grave, concern. While the capital has fewer overall contaminations, totaling 92, it has tragically recorded eight patient deaths. This translates to an alarming 8.7% fatality rate, the highest among all currently affected areas. In Lac province, particularly around the Kangalom district, the toll stands at 60 cases and two deaths, with a fatality rate of 3.3%. Laboratory analyses further confirm the active circulation of the disease; 27 out of 48 examined cultures tested positive, indicating that 56% of samples analyzed were infected.

Young patients disproportionately affected

Health data reveals another critical characteristic of the outbreak: the median age of those infected is a mere 10 years. Furthermore, the majority of patients arrive in a critical state demanding immediate medical intervention. A staggering 84% exhibit moderate to severe dehydration, a direct and dangerous complication associated with the most virulent forms of cholera. Nationally, the attack rate is estimated at 13.3 cases per 100,000 inhabitants.

The health response relies significantly on a vaccination campaign launched in vulnerable areas. By August 8th, 143,367 people had been vaccinated, achieving 89.1% coverage of the targeted population. However, health teams face numerous obstacles that facilitate disease transmission. These include inadequate access to clean drinking water, deficient sanitation infrastructure, widespread open defecation, high population density in certain localities, and regular population movements. In Lac province, communication challenges further complicate public awareness efforts, patient monitoring, and the coordination of essential health interventions.

To combat the spread, frequent handwashing with clean water and soap is crucial. Consuming only safe drinking water, or water that has been boiled, is also strongly advised. Immediate medical consultation is essential at the onset of sudden diarrhea. Cholera is an acute intestinal infection primarily transmitted through the ingestion of contaminated water or food. Its severe forms can lead to rapid dehydration, which can prove fatal if not treated promptly.
