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.[1]
Epidemiology and Demographics
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.[2]
- 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.[1]
Case Fatality Rate
- The case fatality rate of brucellosis is less than 2% when untreated.[3]
Developed Countries
- Dairy herds in the USA to be certified brucellosis-free are tested at least once a year with the Brucella milk ring test. Many countries such as the US have good surveillance programs.
- Australia, Canada, France, Belgium, Germany, and many other countries are considered to be brucellosis-free.[4]
Developing Countries
- Developing countries often do not have safeguards that can help prevent or monitor possible outbreaks, such as pasteurization laws, animal control/slaughter regulations, and brucellosis surveillance programs.[1]
