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).
Kuigi enamasti ei kaasne nakatumisega haigussümptomeid, võib osadel inimestel siiski tekkida halb enesetunne ja avalduda gripitaolised nähud, nt palavik, külmavärinad, lihasvalud ja väsimus, samuti sapihäirest tingitud nahakollasus.
