Background: Tuberculosis (TB) is one of the
most important health issues in developing countries. Understanding the epidemiology of tuberculosis
is critical for effective disease control. The global burden of tuberculosis,
risk factors for transmission, and the epidemiology of tuberculosis will be
reviewed in this article.
Materials and Method: We used Scopus,
Embase, PubMed, World Health Organization (WHO) and scientific Iranian journals
from 2000 to 2011; and the last reports from Iranian ministry of health, for
extracting data. Key words such as tuberculosis, epidemiology, Iran and Sistan-
Balouchestan were used.
Results: Descending trend of TB incidence was observed over the last 45
years in Iran. Pulmonary TB is the most prevalent kind of TB in Iran in which
53% were sputum smear positive. Extra-pulmonary TB consists 28% of TB patients.
Sistan-Balouchestan and Golestan had the highest incidence and prevalence of TB
among all provinces in Iran. According to the latest data from Iranian ministry
of health, the incidence of TB in Zabol and Zahedan were reported 109.7 and
36.6 per 100000 populations, respectively.
Conclusion: More than 80% of TB patients still belong to
developing countries. Sistan-Balouchestan and Golestan had the highest incidence
of TB and for achieving the goals of WHO, control and prevention of the disease
should be followed seriously [ZJRMS, 2012; 13(9): 1-7].
