Hepatitis A mostly occurs in warmer countries where hygiene is not as good as in Germany. It is often transmitted by unclean water and foodstuffs such as vegetables, fruit, mussels and ice cream. This form of transmission does not usually occur in Germany. Therefore hepatitis A is also called "travel hepatitis".
Infection is also possible during sex, especially if there is direct contact between the mouth and anal area. But the virus can also find its way to the mouth indirectly, via the hands, for example.
