Common symptoms of Ebola virus disease (EVD) patients included fever, fatigue, abdominal pain, headache, and diarrhea.
Compared with patients aged <18 years, those who were older than 40 had a higher probability of death.
Patients with a viral load of >106 copies/ml had a higher case fatality rate than those with <106 copies/ml.
Cox regression showed that age, log viral load, and the presence of diarrhea were correlated with mortality.
