==Overview ==
Worldwide, the incidence of Brucellosis ranges from a low of 0.01 per 100,000 to high of 200 per 100,000 individuals. Case fatality rate is less than 2% when untreated. Brucellosis most commonly affects men in age group between 20 to 45 years old. Areas currently listed as high risk are the Mediterranean Basin (Portugal, Spain, Southern France, Italy, Greece, Turkey, North Africa), South and Central America, Eastern Europe, Asia, Africa, the Caribbean, and the Middle East.<ref name="c">Brucellosis.

Overview

The incidence of brucellosis is estimated to vary from 0.01 to 200 per 100,000 individuals in endemic countries. The case fatality rate of brucellosis is less than 2% when untreated. The majority of disease is reported in Mediterranean basin, South and Central America, Eastern Europe, Asia, Africa, the Caribbean and the Middle East. Patients of age group 20 and 45 years are affected. Men are more affected then women.

Epidemiology and Demographics

Epidemiology and Demographics of Brucellosis include:[1][2][3][4][5]

Incidence

  • The incidence in different endemic countries varies between 0.01 and 200 per 100,000 individuals.
  • The low incidence reported in known Brucellosis-endemic areas may reflect low levels of surveillance and reporting.[3]

Case Fatality Rate

Developed countries

Developed countries like the Unites States (0.02-0.09/100,000), Italy (1.40/100,000), Germany (0.03/100,000) and Greece (4.00/100,00) with strict pasteurization laws, animal control/slaughter regulations and brucellosis surveillance programs have reported low incidence of brucellosis.[6]

Developing countries

Developing countries like Iraq (53.29-268.81/100,000), Iran (0.73-141.60/100,000), Jordon (25.70-130/100,000), Kyrgyzstan (88/100,000) and Mexico (26.60/100,000) due to lack of strict pasteurization laws, animal control/slaughter regulations and brucellosis surveillance programs have reported much higher incidence of brucellosis.[6]
