This repository stores the data associated with the study entitled
“Occupational Patterns and Risks in Work-Related Biological Material Exposures in Brazil, 2015–2019: A Cross-Sectional Study.” (https://github.com/leticiaraposo/ocupacao-riscos-biologicos-brasil-2015-2019/tree/main)

The aim of the study is to characterize the profiles of work-related biological material exposure incidents recorded in the Notifiable Diseases Information System (SINAN) between 2015 and 2019, and to identify patterns associated with these events.

Study Context

• Objective: To identify demographic characteristics, occupational conditions, and types of exposure related to work-related biological material incidents in Brazil.

• Methodology:

  • Multiple Correspondence Analysis (MCA)

  • Hierarchical Cluster Analysis

• Key Findings:

  • Nursing professionals were the most affected group (70.9%).

  • Three distinct occupational clusters were identified:

    1. Cluster 1: Cleaning and maintenance workers with low educational attainment, a predominance of males, and low hepatitis B vaccination coverage.

    2. Cluster 2: Nursing professionals with high vaccination rates, a predominance of females, and incidents primarily associated with medication administration.

    3. Cluster 3: Dentistry and medical professionals with higher educational levels and consistent use of personal protective equipment (PPE).
