Brucellosis is a generalized infection of the body primarily involving the reticuloendothelial system, caused by the brucella species, characterized by intermittent or irregular febrile attacks, with profuse sweating, arthritis and an enlarged spleen. The disease may last for several days, months or occasionally, even years.Brucellosis is one of the major bacterial zoonoses, and in humans is also known as undulent fever, Malta Fever or Mediterranean Fever. It is occasionally transmitted to humans by direct or indirect contact with infected animals.Brucellosis is both a severe human disease and a disease of animals with serious economic consequences.

Problem Statement
Brucellosis is a recognized public health hazard that is found the world over. It is endemic wherever cattle, pigs, goats and sheep are raised in large numbers. The important endemic areas for Brucellosis exist in Mediterranean zones, Europe, Central Asia, Mexico and South America.

Animal Brucellosis has been reported from practically every state in India. However, no statistical information is available about the extent of infection in humans in various parts of the country.

The prevalence of human Brucellosis is difficult to estimate. Many cases remain undiagnosed either because they are not apparent, or because physicians in many countries are unfamiliar with the disease.
