those synthoms match with liver damage and many other illnesses, hbv has those synthoms only rarely on acute, never on cronic.the yellow is bilirubin and it gets abnormal only on acute liver damage or very very advanced cronic damage.acute makes no liver damage once you recover from illness in about 6 months
all tests are in the link but you have to check liver functions blood tests, if you have one available fibroscan to see liver damage if you find abnormal liver functions, all viruses that can make liver damage (hav, hbv, hcv, hgv,hev), unfortunately there are liver viruses for all alphabet but only those i have written are common
