There are various sexually transmitted diseases such as syphilis, gonorrhea, HIV and AIDS, and among all these sexually transmitted diseases are hepatitis viruses which can also be transmitted through sexual contact. In this final paper, the focus is on the hepatitis A, B, C and D viruses. Namely, their numbering is from A to E, and somewhere even G is mentioned, but even the hepatitis D virus is not that widespread in our area. All hepatitis viruses are equally important, therefore it is necessary to pay attention to each of them and, if an infection occurs, prevent and treat them in time. The hepatitis virus mostly affects the liver organ and it very easily leads to cirrhosis of the liver in case of chronic viruses. Because of this, a liver transplant is also possible. Hepatitis A virus infection does not cause chronic inflammation, while hepatitis B and C viruses do. All types of hepatitis affect different areas, and they also do not choose gender or age of the infected. Taken that in consideration, both adults and newborns can become infected. Children become infected through an infected mother. Hepatitis A virus is also called "dirty hands disease". Namely, it is most widespread in less developed countries where hygiene is very poor. The virus of this hepatitis leads the patient to infectious jaundice but in most cases hospital treatment is not necessary, only good nutrition and rest. Hepatitis B and C viruses cause acute and chronic inflammation. They are a major public health problem and are widespread throughout the world. However, compared to hepatitis A, they have stronger symptoms and a more severe form of the disease. It is very important to detect the virus in time so that the patient can start the treatment as soon as possible to prevent further transmission of the infection. Moreover, the importance of prevention should be highlighted because infected people are a constant source of infection. The implementation of preventive measures is divided into three forms of prevention: primary, secondary and tertiary prevention. They are conducted by healthcare professionals such as medical nurses and technicians. Various preventive measures are used and a lot of money is invested in material resources when it comes to hepatitis viruses. The education of nurses/technicians, doctors and support staff who care for those infected with the hepatitis virus is just as important as the prevention is.
