The hepatitis E virus is an RNA virus with 4 genotypes.
Genotypes 1 and 2 only affect humans and produce epidemic acute hepatitis in endemic regions (Asia and Africa). Genotypes 3 and 4 are considered a zoonosis and produce episodic acute hepatitis in non-endemic areas (America and Europe). However, in the last 3 years there have been cases of chronic HEV hepatitis, mainly in immunosuppressed patients.
Here we review the known data of chronic hepatitis E in terms of evolution and treatment.
