Factors Influencing Fatal Outcome during an Outbreak of Cholera, Gadarif, Sudan

We studied risk factors associated with fatal outcome of cholera patients during the outbreak in Gadarif State, Sudan in 2023 using the surveillance data and patients' medical records, Forty-six out of 1,904 patients with cholera died (case-fatality rate [CFR] 2.4 (95 CI: 1.8-3.2). The CFR among females patients (2.84, 95 CI: 1.86-4.13), (p>0.05) from CFR among males (CFR=2.34, 95 CI: 1.43-3.59). The CFR among patients aged 70 years or more was 3.81 (95 CI: 1.05-9.47). The mean (SD, IQR) of the duration between the onset of diarrhea and reaching the CTC was 0.58 (1.27, 0.0–1.0) and 0.5435 (0.81, 0.0–1.0) days for survivors and fatal cases (p>0.05). Unconditional multi-variate analysis revealed that patient is living in a rural area were more likely to die from cholera than others (OR= 3.28, 95% CI: 1.61-6.68). We concluded that accessibility to medical services during cholera outbreaks are critical to reduce CFRs.
