Retrospective study analyzes dengue incidence and mortality in Santa Catarina, indicating rising trends and risk factors.

Key Points

  • The study aims to describe the epidemiological profile of dengue in Santa Catarina from 2015 to 2024.
  • Retrospective analysis using data from the Notifiable Diseases Information System (SINAN)
  • Inclusion of confirmed dengue cases classified by macro-regions
  • Calculation of mortality, lethality, and incidence rates per 100,000 inhabitants
  • Statistical association analysis using Fisher’s exact test
  • Creation of thematic maps in QGIS for incidence and lethality visualization.
  • Confirmed 556,695 dengue cases and 414 deaths between 2015 and 2024.
  • Incidence rate decreased by 51.6% from 2015 to 2019 but increased by 14,869.5% up to 2024; peak incidence was 3,875.9 cases/100,000 inhabitants.
  • Most cases occurred among females (52.1%) and young adults (20-29 years, 19.0%).
  • Significant association between sex and death (OR = 1.3, p=0.006); older adults (≥60 years) had higher lethality rates.
