[Quantitative methods of assessing the severity of an epizootic situation].
n order to evaluate the epizootic status of a particular territory for a given moment or a period of time with regard to the infectious diseases one has adopted Tarshis ' formula. The present work deals with the comparative approbation of this formula, using a modified formula in which a parameter characterizing the intensity of the epizootic process was introduced. The epizootic situation and its severity was determined by the two formulas for each district of the country with regard to the following infectious diseases: gangrenous mastitis and listeriosis of sheep, swine erysipelas, and anthrax of all kinds of farm animals--all for the 1970-1981 period. A categorization of the districts is effected according to the values obtained. It was found that the modified formula is important for the objectivization of the severity of the epizootic status as it reflected also the territorial spread and intensity of the epizootic process.
