As many as 31 Â children have been diagnosed with Hepatitis A as public health officials warn that the number may increase.
As these cases are affecting school age children, Â the health officials are working with nine schools and affected parents to assess risk and provide advice.
â€œThis is an evolving situation and an increase in cases was expected following the assessment of close contacts,â€Â Dr Shanika Perera, Medical Officer of Health for Auckland Regional Public Health Service says.
TheÂ most likely source of the outbreak is one or more importations of infection due to people travelling overseas, says the Health Service.
Hepatitis A is a mild illness, particularly in children. Symptoms in children usually include fever, an upset stomach, and feeling tired and generally unwell. Many children do not show any signs that they have been infected. Very occasionally children develop jaundice, a yellowing of the skin and the whites of the eyes.
Hepatitis A is excreted from the body through faeces, it can be spread from person-to-person or by swallowing food or water that has been contaminated. The best way to prevent the spread of the infection is careful hand washing with soap and proper drying, especially after using the toilet and before eating.
â€œThe most important way to prevent spread of this disease is to wash your hands regularly with soap and warm water, particularly after going to the toilet and before eating.â€ said Dr Perera.
