Analysis of the epidemiological characteristics of pulmonary tuberculosis in Shangluo City, Shaanxi Province from 2010 to 2022

Abstract

Background:
Pulmonary tuberculosis (TB) remains a major public health challenge in China, particularly in less developed regions. Understanding its epidemiological characteristics over time is crucial for designing effective control strategies.
Objective:
To analyze the epidemiological trends and characteristics of pulmonary tuberculosis in Shangluo City, Shaanxi Province, from 2010 to 2022.
Methods:
Data on reported pulmonary TB cases from 2010 to 2022 were obtained from the national disease surveillance system. Indicators analyzed included annual incidence rates, demographic distribution (age, sex), seasonal trends, and spatial distribution across the city’s districts. Time-series analysis was conducted to assess trends over the study period.
Results:
A total of [XXX] pulmonary TB cases were reported over the 13-year period. The overall incidence rate showed a [declining/stable/fluctuating] trend, decreasing from [X/100,000] in 2010 to [Y/100,000] in 2022. The highest incidence was observed in males, particularly in the [age group] age group. Seasonal peaks occurred in [months/seasons]. Certain districts exhibited higher case concentrations, indicating spatial clustering.
Conclusion:
The burden of pulmonary TB in Shangluo City has [declined/remained significant] over the past decade but continues to display marked demographic, seasonal, and spatial patterns. Targeted interventions focusing on high-risk populations and areas are recommended to further reduce TB transmission.
