Analysis Of Disease-Causing Microorganisms In Semarang City 2023

This study aims to analyze the prevalence and distribution of disease-causing microorganisms in Semarang City in 2023. The increase in infectious disease cases in urban areas, including Semarang City, demonstrates the urgency of mapping the distribution of pathogenic microorganisms as a basis for formulating public health strategies and analyzing their relationship with demographic factors and disease types. Data were obtained from 3,803 laboratory samples collected at hospitals and community health centers, then analyzed descriptively quantitatively based on frequency, percentage, patient age, region of origin, and disease classification using ICD-10. The results showed that Escherichia coli (13.12–16.60%) and Acinetobacter baumannii (11.68–14.78%) were the dominant microorganisms, followed by Staphylococcus epidermidis, Klebsiella pneumoniae, and Pseudomonas aeruginosa. The highest distribution of cases was found in the productive age group (20–65 years, 58.7%), followed by the elderly (21.1%) and infants <2 years (12.1%). Bronchopneumonia (J18.0) was the most common diagnosis, with a significant prevalence also in congenital pneumonia (P23.9) and cerebral infarction (I63.9). These findings confirm the close relationship between population density, environmental sanitation, and the vulnerability of certain age groups to microbial infections. This study concludes the need for strengthening data-driven policies, improving infection control in healthcare facilities, and public health education to reduce the burden of infectious diseases in Semarang City.
