Hepatitis A

Hepatitis A is a viral disease that affects the liver. The hepatitis A virus is transferred through contact with contaminated food and water or with an infected person. The illness is self-limiting and does not cause chronic infection.

Cases of hepatitis A are reported across all age groups in New Zealand, as stated by Immune NZ. Many of the cases reported overseas travel immediately prior to symptoms (during incubation period). In 2015, there was a small cluster of cases linked to the consumption of imported frozen berries.

How do you get hepatitis A?

The Hepatitis A virus is transmitted via the faecal-oral route by consumption of contaminated food such as raw shellfish, water or milk or close contact with an infected person/persons.

There are certain groups of people who are at a higher risk from this infection as stated by Immune NZ, these include:

  • Injecting drug users
  • People with chronic liver disease or who at risk of developing chronic liver disease.
  • Occupational groups who may be exposed to faeces, these include:
  • Employees of early childhood centres
    Healthcare workers
  • Sex industry workers
  • People working with sewerage and members of the armed forces.
  • Travellers to moderate and high-risk countries
  • Men who have sex with men.


  • Fever
  • Tiredness
  • Nausea

Symptoms are usually seen in older children and adults from 15 -50 days after infection. Young children may not have any symptoms. Symptoms can last for several weeks but no more than two months.
