As of August 8, Chad had officially registered 320 cholera cases and 15 deaths. A rapid assessment over a 72-hour span revealed an additional 52 new contaminations. The national case fatality rate has now escalated to 4.7%, a figure significantly exceeding the 1% benchmark typically associated with effective disease management. The outbreak currently impacts three distinct provinces: Hadjer-Lamis, Lac, and the bustling city of N’Djamena. Across these regions, a total of 58 villages and urban neighborhoods, spanning twelve active health zones, have reported instances of the illness.

The Hadjer-Lamis province continues to bear the brunt of the epidemic, reporting the highest number of patients. Within this province, the Karal district alone accounts for 168 cases and five deaths, translating to a 3% case fatality rate. N’Djamena presents a contrasting, yet equally dire, scenario. While the capital has fewer overall infections, with 92 cases, it has recorded a distressing eight fatalities. This gives N’Djamena an alarming case fatality rate of 8.7%, making it the highest among all currently affected areas. Meanwhile, in the Lac province, particularly around the Kangalom district, 60 cases have been identified, resulting in two deaths and a 3.3% lethality rate. Laboratory analyses further corroborate the active spread of the disease, with 27 out of 48 cultures examined returning positive results, representing 56% of all samples tested.

Young patients particularly affected

Health data reveals another critical aspect of the outbreak: the median age of those infected is a mere 10 years old. Furthermore, most patients arrive at medical facilities in a state demanding immediate care. A staggering 84% exhibit moderate to severe dehydration, a severe complication directly linked to the most perilous forms of cholera. Nationally, the attack rate for the disease is estimated at 13.3 cases per 100,000 residents.

The ongoing health response primarily hinges on a robust vaccination campaign implemented across vulnerable areas. By August 8, a total of 143,367 individuals had received the vaccine, achieving 89.1% coverage of the targeted population. However, health teams face significant challenges posed by several factors that facilitate disease transmission. These include inadequate access to safe drinking water, deficient sanitation infrastructure, widespread open defecation, high population density in certain communities, and frequent population movements. In the Lac province, communication hurdles further impede public awareness campaigns, patient tracking, and the overall coordination of health interventions.

Health authorities strongly advise frequent hand washing with clean water and soap, consuming only safe drinking water (either bottled or pre-boiled), and seeking immediate medical attention if sudden, severe diarrhea occurs. Cholera, an acute intestinal infection, is predominantly transmitted through the consumption of contaminated water or food. Its most severe manifestations lead to rapid dehydration, which can prove fatal if not treated promptly.
