Examination of 60,792 residents of Minsk in different seasons of 1977-1989 by indirect immunofluorescence showed this method to be able of recoding not only mono- but also polyetiological epidemics. The epidemic threshold for influenza A is 15% of positive findings, for influenza B is 7-8%, for polyetiological epidemics (influenza A and B) is 15-16% and 9-10%, respectively. The criterion of the epidemic situation in the city is a twofold increase (or higher) in the level of influenza A and B virus antigen findings in rhinocytological preparations as compared with the previous week.

A relation between the tick-borne encephalitis morbidity, to the cattle-breeding methods and specific and quantitative structure of dairy cattle herds in developed regions is discussed. This relation is due to the fact that cows and goats are Ixodid hosts and donors of the virus. The factors like use of ameliorated pastures in cattle-breeding practice and cattle maintenance in the stalls deprive ticks of their hosts and donors of virus. It brings to decrease of vector density, valence of foci and human morbidity. On this basis, the prognosis of human morbidity in Byelorussia is given for the following decade.
