Su'ega HAV IgM Pepa e le'i tipiina

O le Hepatitis A e mafua mai i le siama o le hepatitis A (HAV) ma e tele lava ina feavea'i e ala ile fecal-oral auala, tele lava mai gasegase.O le taimi faʻamaʻi o le hepatitis A e 15-45 aso, ma o le siama e masani ona i ai i le toto o le tagata maʻi ma feces 5-6 aso aʻo leʻi siitia le transcarbidine.A maeʻa le 2 ~ 3 vaiaso o le amataga, faʻatasi ai ma le gaosiga o faʻamaʻi faʻapitoa i le serum, o le faʻamaʻi pipisi o le toto ma feces e faasolosolo malie lava ona mou atu.A'o fa'ama'i fa'aaliali po'o fa'alilo fa'ama'i o le hepatitis A, e mafai e le tino ona gaosia ni mea fa'ama'i.E lua ituaiga o antibodies (anti-HAV) i serum, anti-HAVIgM ma anti-HAVIgG.Anti-HAVIgM e vave aliali mai, e masani lava ona iloa i totonu o ni nai aso talu ona amata, ma o le taimi o le jaundice e maualuga, o se faailoga taua mo le vave suʻesuʻeina o le hepatitis A.
