Brucellosis is more prevalent in developing countries especially in IRAN.
Knowledge of the epidemiologic pattern of the disease may prevent the transmission
of disease. From 1997 to 2002 all patients attended to Department of Infectious
Diseases of Babol Medical University were entered in this study. Of 581 cases (329
males, 252 females) with the mean age of 31.9±17 years were evaluated. Among
them, 111 cases were less than 15 years old. 222 cases (39.4%) was seen in urban
regions, and the disease was seen in summer and autumn in 61% of cases. In 350
cases (60.3%), we have not found any risk factors for brucellosis. In 25 individuals,
brucellosis was seen in = 2 cases in every family members. 541(93%) cases had
acute and subacute presentation and only 384 cases (60%) were diagnosed as
having brucellosis for less than one month after the onset of disease. This study
shows that because of the lack of any risk factors in more than half of the patients
and seasonal trends of this disease in our regions, it seems that consumption of
common food, like meat and its products and also ice-cream and other dairy products
may cause disease, which must be clarified.

Brucellosis morbidity rate in humans is 2,000 to 2,500 per year in the Republic
of Kazakhstan. Highest morbidity (400-700 cases per year) has been registered in
South Kazakhstan, where stock-raising is the main business. It can be explained by
an ongoing (over 10 years) and wide-spread brucellosis epizootic among sheep
owned by private farmers. There is an administrative unit in South Kazakhstan,
where human brucellosis is found in everyone fourth of five villages. Livestock is
continuously infected with brucellosis, as there are many small private farms (having
50 to 200 sheep), common grazing areas for a community of 20 to 30 farmers, and
there is no control over barter deals involving sheep. It would be inefficient to take
any anti-epidemic measures within one farm having Brucella-infected animals and
brucellosis patient. Mass vaccination of animals for brucellosis undertaken over the
last 5 years has not shown any effect on brucellosis morbidity in humans. Currently, it
is not possible to early diagnose brucellosis because of big quantities of sheep in
these areas and high costs of livestock preventive examination. It has been found
that groups of people and families (5 persons and over) get sick with brucellosis in
these administrative units. Local authorities announced quarantine in several
villages. These measures were taken in five villages in the course of 1999-2001. No
brucellosis cases were registered among the communities and livestock in the
following three years. Therefore, the only method to combat brucellosis in the
