Prevalence and Epidemiological Profile of Patients with Malaria at the Torrock District Health Center from December 2025 to January 2026

Abstract

In Chad, as in the rest of sub-Saharan Africa, malaria is endemic and epidemic, and epidemiological data continue to evolve at all levels. The objective of this study was to determine the prevalence of malaria and to establish the epidemiological profile of patients with malaria in order to gain insight into trends in its morbidity. To achieve this objective, a descriptive cross-sectional study was conducted at Torrock District Hospital from December 2025 to January 2026 among 241 patients who had been prescribed a thick blood smear or a rapid diagnostic test and who consented to participate in the study. A questionnaire designed in accordance with our objectives was then administered to this study population, and the resulting data were subsequently processed using simple tabulation. Our investigations revealed a malaria prevalence of 48.54%, with severe malaria (86.32%) predominating over the uncomplicated form. Consequently, the most commonly used antimalarial drug in treatment was artesunate. The study population showed a female-to-male ratio in favor of females; the dominant age group was 0 to 10 years; there was a preponderance of unmarried individuals; and the overall level of education was very low. Although 95% of the population owned an insecticide-treated bed net, this prevalence of malaria observed during a season of low transmission indicates that the disease remains a public health problem in our region.
