Summary

  • HEV infection is usually self-limited but immunosuppressed patients (eg, transplantation recipients, patients receiving chemotherapy, or patients with HIV) are at risk of developing chronic infection[Kamar 2010; Koning 2013; Ollier 2009; Dalton 2009]
  • The diagnosis of chronic HEV infection may be considered when HEV infection persists for more than 3-6 months[Kamar 2013]

    • Diagnosis may be challenging due to the absence of symptoms, limited availability and variability of HEV assays, and the complex setting of immunosuppressed transplantation
