Abstract
Background
The collapse of the healthcare system during the recent armed conflict in Sudan has facilitated the emergence and expansion of vector‑borne diseases, particularly malaria and dengue fever, into regions historically considered non‑endemic. Population displacement, environmental disruption, and breakdown of public‑health infrastructure have contributed to increased transmission and atypical epidemiological patterns. This study investigates the frequency of malaria and dengue virus infections among patients attending insurance‑based medical clinics in Shendi City, River Nile State, during the outbreak period.
Methods
A descriptive cross‑sectional study was conducted using routinely collected clinical records from eight insurance medical clinics between December 2025 and June 2026. Extracted variables included age, sex, diagnostic modality, and infection type. Malaria diagnosis was performed using thick blood‑film microscopy and immunochromatographic rapid diagnostic tests (RDTs). Dengue virus infection was assessed using immunochromatographic antigen/antibody assays. Data were analyzed using Microsoft Excel 2016.
