In fact, viral hepatitis is one of the serious health problems of people. Because 500 million people in the world are infected with hepatovirus, and 80% of them do not have the opportunity to be examined and treated. Viral hepatitis A takes an important place among them. The fact that this disease is widespread among children, who are our future heirs, shows that it is necessary to deeply study not only the methods of treatment of this disease, but also the causes of its origin. Viral hepatitis A disease is becoming an important socio-economic problem today. A lot of research is being conducted all over the world, including in Uzbekistan, to study viral hepatitis A. However, despite research, spreading rate of disease among children is increasing significantly. Hepatitis A is an acute disorder that spread by fecal-oral agents and is often followed by a relapse for a few weeks. It is the causative agent of infectious hepatitis. Although children are more likely to contract hepatitis A than adults, the symptoms are usually much milder than those of adults. 90% of the childhood infections are asymptomic.
