BACKGROUND Prolonged infectious diarrhoea in the returning traveller is generally caused by protozoal and occasionally by helminth parasites. OBJECTIVE This article provides a framework for the diagnosis, management and prevention of the diseases that cause persistent diarrhoea in the traveller. DISCUSSION A large proportion of disease is caused by Giardia lamblia, Cryptosporidium parvum an...

During summer 2009, the UK experienced one of the highest incidences of H1N1 infection outside of the Americas and Australia. Building on existing research into biosecurity and the spread of infectious disease via the global airline network, this paper explores the biopolitics of public health in the UK through an in-depth empirical analysis of the representation of H1N1 in UK national and regi...

Landmarks are crucial elements of route instructions given by humans. The currently accepted qualification of an object as a landmark is dependent on spatial dimensions, i.e. visual, semantic and structural dimensions. However, even if an object qualifies as a landmark because of its spatial dimensions, its selection by a traveller as wayfinding aid is further influenced by the knowledge and ex...

Does there exist a purely quantum mechanical carrier of the imprints of gravitation? The motivation for considering this question arises from the following historical scenario: Suppose a time traveller from today visited Einstein in 1907, when he had the “happiest thought of his life”, just in time before Einstein actually started on the path which led towards his formulation of gravitation (ge...

This study proposes a behavioural intention model that integrates information quality, response time, and system accessibility into the original technology acceptance model (TAM) to investigate whether system characteristics affect the adoption of Web-based advanced traveller information systems (ATIS). This study empirically tests the proposed model using data collected from an online survey o...

BACKGROUND Traveller's diarrhoea is among the most frequently reported problems for travellers. Prevention remains a challenge in travellers and the appropriate management of traveller's diarrhoea remains paramount. OBJECTIVE This article provides an overview of the general approach to diarrhoea in the returned traveller, including identification of common causes and management. DISCUSSION ...
