Surveillance of global, travel-related illness using a novel app: a multivariable, cross-sectional study.

Introduction: Current traveller health surveillance is 'top-down'. Mobile-based surveillance could capture infection symptoms in real time. We aimed to evaluate the spectrum of illness in travellers using a mobile app-based system.

Travel-related respiratory symptoms and infections in travellers (2000-22): a systematic review and meta-analysis.

Background: Respiratory tract infections (RTIs) are common in travellers due to the year-round or seasonal presence of respiratory pathogen and exposure to crowded environments during the itinerary. No study has systematically examined the burden of RTI infections among travellers. The aim of this systematic review and meta-analysis is to evaluate the prevalence of RTIs and symptoms suggestive of RTIs among travellers according to risk groups and/or geographic region, and to describe the spectrum of RTIs.

[Rising temperatures and the threat of malaria in Europe: an unwelcome return?].

Rising temperatures pose a threat to malaria transmission in Europe. Anopheles vectors are becoming more stable and widespread, putting some areas at increased risk of transmission for extended periods. By 2030 or 2050, the period of susceptibility is expected to extend to 3-6 months in some European countries and Anopheles mosquitoes are expected to migrate northward.
