It can stay on hands for several hours and in food kept at room temperature for considerably longer. It is relatively resistant to heat and freezing. * How is Hepatitis A transmitted? Hepatitis A is predominantly transmitted by the faecal oral route. Eating food from contaminated water or eating food prepared by unclean hands. HEPATITIS B * What is Hepatitis? Hepatitis is inflammation of the liver. It has a number of different causes, but the most common is damage by a virus. Hepatitis B is one of the viruses which can damage the liver. The outcome of Hepatitis B infection depends largely on the age at which it is contracted. The incubation period is 45 to 180 days. Symptoms include fever, jaundice (yellow colour to skin) anorexia, vomiting and nausea, right abdominal pain, dark coloured urine and light coloured faeces. * How is it transmitted? Hepatitis is spread by contact with contaminated blood, through a break in the skin, where it enters another person's blood stream. Ref: 1. NHMRC - Australian Immunisation Handbook - 8th Edition. 2.
