Analysis of the Epidemiological Trend of Tuberculosis in Sistan and Baluchestan Province during 2015-2019

Introduction: Tuberculosis is one of the oldest and best-known diseases that has been with mankind for many years. Despite the reduction of infectious diseases in Iran, tuberculosis still remains in some parts of the country, especially in the south of Iran. The aim of this study was the epidemiological investigation of tuberculosis in Sistan and Baluchistan Province. Methods: The current research was conducted cross-sectionally in 2022. The study population included all the patients with tuberculosis in Sistan and Baluchistan Province. Data were collected by census method and using standard checklist. Data analysis was done using SPSS v16 software and descriptive and analytical tests. Results: In this study, the files of 5382 patients with tuberculosis in Sistan and Baluchistan Province were examined. 2489 patients (42.6%) were men. The most affected group were 2309 elderly people (39.5%) and 20 patients (0.34%) with HIV. The number of 4309 patients (73.8%) were suffering from pulmonary tuberculosis. There was a significant relationship between the elderly age group (P=0.04), female gender (P=0.02), non-Iranian nationality (P=0.02), and urban residences (P=0.03) with tuberculosis. However, no significant relationship was observed between marital status (P=0.06) and prison history (P=0.07). Conclusion: The incidence of tuberculosis fluctuated during the five years, but the overall incidence has been decreasing. Considering that some factors such as age groups, gender and symptoms such as cough, weight loss and chest pain increase the chance of contracting the disease. Therefore, doctors of health centers can take an important step in reducing the incidence of tuberculosis with timely visits and regular monitoring of the treatment process of patients.
