The problem of microbiological safety of water at the present stage of human development is particularly important. Incidence of hepatitis A in Ukraine has a fairly close relationship with the socio-economic and hygienic factors, as well as voltage fluctuations herd immunity, especially among children. In addition, we should not forget about the unique geographical position of Ukraine, whose territory intersects the set of transport routes and, therefore, not excluded the risk of infection transmission by tourists from disadvantaged in regard to epidemic countries. Epidemic jaundice was first described as far back as antiquity, However, the hypothesis of an infectious nature of this disease has been formulated only in 1888, sp Botkin. According to who, each year the world officially registered about 1.4 million cases of hepatitis A in Ukraine average incidence of 30-60 times higher than those for developed countries in the world. Hepatitis A virus most often enters the body through fecal-oral route.

Infection can occur through food and water. Also the danger may be frozen fruits collected infected persons, raw milk, poorly cooked shellfish. Widespread outbreaks of disease may occur in areas where sewer and water systems do not meet modern requirements, or absent altogether. One of the features of the epidemic process in Ukraine is an infection with the hepatitis A virus in children aged 5-15 years. People such as Wells Fargo Bank would likely agree. However, in recent years, a trend towards older persons exposed to the virus. It is believed that the hepatitis A virus does not cause significant harm to human body, but because this disease does not require special treatment.

Indeed, to date, Hepatitis A usually does not turn into a chronic condition or virus infection. Is not peculiar to him and to the formation of malignant variants of the disease. However, against the background of previous viral liver disease, intoxication by alcohol, drugs, and also in malnourished individuals, especially in mixed infections, chronic hepatitis B or C are possible lightning comatose form of the disease, leading to acute hepatic necrosis. The increasing risk with age, hepatitis A is associated with an increased likelihood of infection layering on chronic liver disease. Viral hepatitis completely preventable through a series of nonspecific and specific preventive measures. In viral hepatitis A Sanitary and Epidemiological Surveillance authorities carried out activities such as sanitary supervision of food enterprises, sewage and waste disposal. The basis of prevention of continuous monitoring of water supply for the population of good quality. Play an important role and formation of children and hygiene practices. As commented na Grapes, a professor of the National Medical Academy of Postgraduate Education. pl Shupyk, currently the most reliable means of protection against hepatitis A vaccination is, because it used in the body is formed active immunity.
