Fatal Puumala Hantavirus Disease: Involvement of Complement Activation and Vascular Leakage in the Pathobiology

Open Forum Infect Dis. 2017 Oct 21;4(4):ofx229. doi: 10.1093/ofid/ofx229. eCollection 2017 Fall.

Abstract

The case-fatality rate of hantavirus disease depends strongly on the causative hantavirus, ranging from 0.1% to 40%. However, the pathogenesis is not fully understood, and at present no licensed therapies exist. We describe fatal cases caused by Puumala hantavirus indicating involvement of complement activation and vascular leakage.

Keywords: Puumala virus; case-fatality rate; complement; hantavirus; vascular leakage.
