What this trial studies

This study aims to identify the incidence of travel-related illnesses among individuals traveling to emerging countries. It focuses on understanding the behavioral, geographical, and environmental risk factors associated with these health issues, including gastrointestinal and respiratory infections, malaria, and road traffic accidents. The study includes two sub-studies: EOP-Arbo, which investigates the risk of arboviral diseases through blood sample collection, and EOP-AMR, which examines antibiotic-resistant bacteria through fecal sample collection. The findings will help develop targeted recommendations to minimize health risks for travelers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are preparing to travel outside mainland France and have a smartphone for data collection.

Not a fit: Patients traveling for less than 3 days or more than 12 months, or those unable to provide consent, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved health recommendations for travelers, reducing the incidence of travel-related illnesses.

How similar studies have performed: Other studies have shown success in identifying travel-related health risks, making this approach both relevant and necessary.
