[The effect of an unfavorable epizootic situation on the basic epidemiological indices for tuberculosis]

Analysis is given of the basis of epidemiological parameters in two districts of the Novosibirsk region, depending on the duration of the unfavourable epizootic situation. Subjects with extensive residual changes were registered 10 times as often in the district with the unfavourable epizootic situation as in the district with fresh tuberculosis outbreak in animals. Studies of infectivity among children and adolescents at the height of tuberculosis outbreak in animals showed that reversion was established in 8.6%, while the share of children with hyperergic reactions increased by 4 times and exceeded the average regional index by 8 times. Children and adolescents from the district with the unfavourable situation for tuberculosis had a low level of reversion (0.3%), but the level of infectivity in children of the decreed ages was high. The complex of health-improvement, prophylactic and veterinary measures has been suggested.
