Epidemiological features of human brucellosis in central Iran, 2006-2011

Brucellosis is still one of the most challenging issues for health and the economy in many developing countries such as Iran. This study investigated the epidemiological features of brucellosis in Isfahan province in central Iran.

This retrospective descriptive study was planned to determine the epidemiological features of brucellosis in central Iran, as this is one of the most endemic areas in the country.

Data collection was performed using epidemiological questionnaires from the private and public sectors over a 4-year period (2006-2009).

In total, 1996 cases of brucellosis were reported. The incidence of brucellosis decreased from 17.1/100,000 in 2006 to 8.2/100,000 in 2009. The male:female ratio was 2.1, and the disease was most common in individuals aged 15-20 years. Sixty-eight percent of cases were from rural areas, and the animal contact rate was 81% in rural cases and 61% in urban cases. Raw milk was the most commonly consumed dairy product, consumed by 37% of cases.

Health-related interventions need to empower communities at risk, especially young men and adult women in the western districts of Isfahan province. Public health promotion is needed for control of risk factors in these areas.
