incubation period is 15 to 50 days.
transmission occurs via the faecal-oral route through the ingestion of contaminated food or water, or through direct hand-to-mouth contact with the faeces of an infectious case.
patients may present with symptoms such as loss of appetite, nausea and vomiting, tiredness, fever, abdominal pain, dark urine, pale faeces and jaundice.
Cases are infectious two weeks before and one week after the onset of jaundice/dark urine (whichever is first).
Normal Human Immunoglobulin (NHIG) or the hepatitis A vaccine can be given as post-exposure prophylaxis.
The health department currently provides NHIG free of charge to contacts of hepatitis A cases. This can be arranged by the department and delivered to your practice during normal working hours.
If required urgently, NHIG can be obtained after hours by contacting the CSL after hours telephone number on 0413 027 298.
NHIG doses: <25kg = 0.5ml; 25-50kg = 1.0ml; >50kg = 2.0ml;
NHIG injection should be given by deep IM injection using a large (19 or 20) gauge needle.
Please note that NHIG can potentially interact with vaccines
