Short Summary

This study conducted epidemiological surveillance of acute gastroenteritis (AGE) in six municipalities within the Valencia-La Fe department following an isolated depression at high levels (DANA) event. It found 518 DANA-related AGE cases, predominantly in resident men aged 17-49, with Campylobacter being the most isolated pathogen, and weekly AGE rates generally not exceeding historical expected values.

Objective

• To examine the results of epidemiological surveillance conducted in municipalities belonging to the Valencia-La Fe department as a consequence of the DANA, using expected values based on the last two years published by the General Directorate of Public Health in weekly epidemiological situation reports after the DANA.

Study Configuration

• Spatial Scale: Six municipalities (Albal, Alcàsser, Beniparrell, Catarroja, Massanassa, and Silla) within the Valencia-La Fe department, affected by the DANA.
• Temporal Scale: From epidemiological week 45 of 2024 to epidemiological week 11 of 2025.

Methodology and Data

• Models used: Epidemiological surveillance system (AVE - análisis de vigilancia epidemiológica).
• Data sources: Data extracted from surveys of DANA-related AGE cases included in the AVE system; historical epidemiological situation reports from the General Directorate of Public Health for expected values.

Main Results

• A total of 518 DANA-related AGE cases were registered and surveyed.
• The majority of cases (49.03%) were declared between week 45 and 48 of 2024.
• 52.9% of cases were men, and 47.10% were women.
• The age group 17-49 years accounted for the highest percentage of cases (40.35%).
• Most cases (93.63%) were residents of the affected municipalities.
• 173 samples were taken, with 91 positive results.
• The main pathogens isolated were Campylobacter (32.97%), Norovirus (20.88%), enteropathogenic E. coli (19.78%), Salmonella (9.89%), Astrovirus (5.49%), and Aeromonas spp (4.4%).
• Weekly AGE rates generally did not exceed historical expected values.

Contributions

• This study provides specific, real-world epidemiological data on the impact of a natural disaster (DANA) on public health, particularly regarding acute gastroenteritis outbreaks. It quantifies the number of cases, identifies key demographic groups affected, and isolates predominant pathogens, offering valuable insights for public health response and preparedness in post-disaster scenarios by comparing observed rates to historical trends.
