The most common infection occurs through the alimentary tract, through the consumption of food and water contaminated with the patient's faeces. The virus develops most rapidly in countries with very poor sanitary conditions, most often in South America, Southeast Asia or Africa. In addition, HAV is often found among people working in hospitals, sewage treatment plants, schools, or among traders. Hepatitis A is transmitted through dirty hands or contaminated food. A visit to a nurse or doctor before departure can protect the traveler from infection or help in the earlier diagnosis of the disease and the possibility of faster treatment. The aim of the study is to increase knowledge and the importance of prophylaxis and vaccinations among travelers at risk of contracting hepatitis A.

Key words: Hepatitis A, nurse, prevention, education.
