Epizootiology is a science which studies origin, distribution, frequency, development, determinants and extinction of animal health and disease at population level and based on their analyses defines and applies methods for creation, promotion, protection and restoration of population health by reducing, eliminating and eradicating diseases.
Note: Epizootiology covers a l l s p e c i e s of a n i m a l k i n g d o m while veterinary epidemiology covers animal species of veterinary importance. From biology science hierarchical point of view the epizootiology includes also human epidemiology (Homo sapiens belongs to animal kingdom).
Calvin Schwabe wrote in his book “Veterinary Medicine and Human Health”,
The mission of modern action-oriented and problem-solving epizootiology is to create, promote, protect and restore animal population health, to protect the man against diseases transmissible from non-human species, to contribute to the improvement of animal performance and welfare, and thereby, to the betterment of public health, economic and social development of contemporary and future society.
Note: Selection and practical application of the most suitable epizootiological principles and methods reaching, under any conditions (sanitary, ecological, social, economic etc.), with minimal inputs the best possible results in animal population health protection and recovery, is a very demanding professional a r t.
