Introduction :

• Bangladesh has an estimated TB prevalence of 221 per 100,000 population.
• The country contributes approximately 3.6% of the world’s total TB cases.
• Bangladesh remains among the top 30 high TB-burden countries globally.
• This study analyzes the geographical distribution and demographic impact of TB within the country.

Methodology :

• Statistics were compiled from WHO, National Tuberculosis Control Programme (NTP), and specific research findings.
• Geospatial heat maps and demographic charts were developed using R Programming.
• Data was analyzed based on total case counts, prevalence rates per 100k, gender ratios, and age groups.
• Interactive heat maps and demographic charts were developed using R programming (packages like Leaflet and ggplot2) to identify geographical clusters and hotspots.

Results :

• Dhaka division recorded the highest volume with 80,137 cases.
• Sunamganj (840) and Netrokona (640) show the highest prevalence rates in the country.
• Global data shows Lesotho (661) and Philippines (638) have some of the highest incidence rates.
• Bangladesh (221) is positioned among the high-burden countries in the global heat map.
• Male cases account for ~65% and pediatric cases account for 10–12% of the total.
• Annual deaths are estimated between 4,000–6,000.

Discussion :

• While Dhaka has the most cases due to population density, rural districts like Sunamganj have a higher intensity of infection.
• The global heat map analysis shows that Bangladesh’s incidence (221) is higher than neighboring India (199) but lower than Myanmar (475).
• High-prevalence countries like Lesotho and Central African Republic (540) show similar risk patterns to Bangladesh’s high-risk districts.
• The high male percentage indicates a potential occupational risk or higher exposure in public spaces.
• Elevated rates in remote areas suggest a need for better healthcare accessibility compared to global standards.

Conclusion :

• Targeted screening is required in high-prevalence districts like Sunamganj and Netrokona.
• Strengthening pediatric TB detection and reducing the male-to-female case gap should be priorities.
• Sustained intervention is necessary to move Bangladesh out of the top 30 high-burden list.
