While most infections pass by without symptoms, some people may become sick and present with flu-like symptoms like fever, chills, muscle ache, fatigue, as well as jaundice (yellowing of the skin due to a bile disorder).
Večina okužb sicer mine brez simptomov, nekateri ljudje pa lahko zbolijo in pri njih se kažejo simptomi, ki so podobni gripi, na primer povišana telesna temperatura, mrzlica, bolečine v mišicah, utrujenost ter zlatenica (porumenelost kože zaradi žolčnih motenj).
