CASES OF PULMONARY TUBERCULOSIS AND POPULATION DENSITY (WITH SPATIAL ANALYSIS APPROACH)

Abstract

Tuberculosis (TB) is a disease caused by the bacterium microbacterium tuberculosis. Mycrobacterium tuberculosis belongs to gram-positive, rod-shaped bacilli with a length of 1-10 microns, a width of 0.2-0.6 microns. Mycobacterium tuberculosis is transmitted by a person through coughing and sneezing, people affected by TB if not treated can die. The purpose of the study is to determine the relationship between the incidence of pulmonary tuberculosis cases and population density in North Sumatra Province per district/city with a spatial analysis approach. The study design used is an ecological study using aggregate analysis units. The data used is new cases of Pulmonary TB per district/city sourced from the North Sumatra Province BPS website in 2022. Population density data (the number of people per city district divided by the area of the area) is sourced from the North Sumatra Province BPS website in 2022. The districts/cities with the largest number of TB cases in North Sumatra province are dominated by districts/cities with a high population density, namely Medan city with 2697 cases, Simalungun district with 1178 cases, Binjai city with 1457 cases, Deli Serdang Regency with 2967 cases. Population density based on the administrative area in each district/city in North Sumatra province cannot be used as an indicator of the high incidence of TB in the area.
