This can be a serious disease which attacks your liver. It can cause chronic illness or death. Some people may be unaware they are infected and show no symptoms. Some may feel like they have the flu. Symptoms can include jaundice, fatigue, loss of appetite, nausea and vomiting, abdominal pain, fever and chills, dark, tea coloured urine, grey or clay coloured bowel movements. Treatments can't cure this STD but simply slow down its development.
