Leveraging traveller genomics for LMIC diarrhoeal disease management.

Traveller-derived genomic data can enhance diarrhoeal disease surveillance and antimicrobial resistance monitoring in LMICs, revealing critical pathogen and resistance patterns.

• Why it matters: Diarrhoeal diseases cause a major health burden in LMICs, but limited microbiological and genomic capacity hampers effective surveillance and treatment strategies.
• What they did: The authors review how high-income countries generate and share extensive diarrhoeal pathogen genomes from travellers returning from LMICs, highlighting the potential to leverage this data for improved local public health decisions.
• The result: Integrating traveller genomics can support geographically detailed surveillance and antimicrobial treatment guidance in LMICs, though ethical, practical, and governance challenges must be addressed.
