[Viral hepatitis E: the epidemiological role of the water factor seen retrospectively and prospectively]

As demonstrated on the basis of clinico-epidemiological diagnostics, large epidemics of viral hepatitis (VH), earlier considered to be the epidemics of VHA, were in reality epidemics of VHE. Such epidemics originated due to the influence of the water factor and were called forth by the drying-up of rivers in Central Asia, which played an important role in their appearance. In combination with unusually high average monthly temperatures, especially in spring and summer, this is an important sign for the prognostication of new water epidemics of VHE.
