On request of the authors, the following changes were made on 12 and 19 November 2012 in the article ‘Infectious diseases among travellers and migrants in Europe, EuroTravNet 2010' by P Gautret et al., published on 28 June 2012:

1. The sentences "All ill patients presenting to EuroTravNet sites are systematically and prospectively included in the GeoSentinel database provided the diagnosis is clinically or laboratory-confirmed and that the causality of travel is confirmed. All patients included in the study were symptomatic, including those with parasitic infections such as malaria and schistosomiasis. Patients with proven chronic Chagas infection, however, were included whether or not they were symptomatic, owing to the potential life-threatening course of the disease." were corrected to read: "All returned travellers presenting to EuroTravNet sites are systematically and prospectively included in the GeoSentinel database provided the diagnosis is clinically or laboratory-confirmed and that the causality of travel is confirmed. Travellers undergoing screening for asymptomatic infections or clinically cured travellers looking for a confirmation of the diagnosis established elsewhere are however also included in the database, with "healthy" as a diagnosis when the screening remains negative. Patients included in the study may be symptomatic or not. For example, patients with chronic infection such as Chagas disease, schistosomiasis, tuberculosis, hepatitis B, were included whether or not they had clinical symptoms at the time they presented."
2. In addition, on 19 November 2012, some numbers were corrected at the request of the authors in the abstract and in the main text (making no interpretation difference).
