Prevalence and risk factors of Hantavirus infection in patients undergoing hemodialysis in Khartoum, Sudan, in 2019: a cross-sectional study

Background Hantaviruses are enveloped negative sense RNA viruses that cause hemorrhagic fever with renal syndrome. This study aimed to identify the prevalence of Hantavirus IgG antibodies and possible risk factors for Hantaviruses infections among end-stage renal disease (ESRD) patients attending the Dr Salma dialysis center in Sudan. Methodology This was a cross-sectional study in which 91 ESRD patients and 30 healthy plasma samples were screened for Hantavirus IgG antibodies using ELISA. A questionnaire containing sociodemographics, history of rat exposure and clinical data information was filled in by each ESRD patient. Results In this study, 9 out of 91 ESRD patients (9.9%) tested positive for Hantaviruses antibodies (IgG) while none of the 30 healthy plasma samples showed seropositivity. There was no statistically significant association between age, gender, educational level and rat exposure and Hantavirus infection in ESRD patients (p>0.05) Conclusion This study is the first to be conducted in Sudan regarding Hantaviruses and ESRD. The prevalence of Hantavirus antibodies among ESRD patients is high compared with findings reported in the literature from studies conducted on the same group of patients. It points to an interesting question as to whether Hantaviruses have an association with ESRD but further studies are needed before drawing any conclusions.
