Analysis of imported malaria in travelers may represent a novel surveillance system for drug-resistant malaria. We analyzed consecutive falciparum malaria isolates from Canadian travelers from 1994 to 2000, for polymorphisms in pfcrt, dhfr, and dhps linked to chloroquine and pyrimethamine/sulfadoxine resistance. Forty percent of isolates possessed the K76 pfcrt allele, suggesting that many impo...

Endemic mycoses, such as histoplasmosis, coccidioidomycosis, and penicilliosis, have emerged as important health threats among travelers to regions of the world where these infections are endemic. Travelers have developed fungal infections as a result of a wide range of recreational and work activities, many of which have involved well-recognized risk factors for these diseases. In some instanc...

Based on a study of ICT use at an airport security checkpoint, this paper explores a possible explanation to the paradox that travelers find existing airport security measures inadequate while at the same time believing air travel to be sufficiently secure. We pursue this explanation by showing that, for the security checkpoint to function properly in relation to the overall function of the air...

Macroscopic and equilibrium-based models for traffic assignment and simulation disregard many details of traffic movement. For some applications, one needs to understand and analyze microscopic properties. This paper discusses an agent-based simulation of route choice under different conditions of demand generation, number, and types of travelers. The effects of en-route decision-making and veh...

BACKGROUND Infectious diseases are a leading cause of morbidity among travelers to resource-limited regions and primary prevention is a cornerstone to risk reduction. Chemoprophylaxis has been successfully utilized for specific diseases. METHODS We assessed self-reported compliance to daily chemoprophylaxis among deployed US military personnel. A 21 item self-completed questionnaire was compl...

Vehicular Ad Hoc Networks (VANETs) are classified as a subset of Mobile Ad Hoc Networks (MANETs). VANETs have the potential of improving road safety and providing travelers comfort. This network rehearses moving cars as nodes in a network to create a mobile network. As a component and concrete application of an ITS inter vehicle communication gained attention from researchers, academics and ind...

This article discusses tourist-activated networks as a concept to inform technological applications supporting dynamic bundling and en route recommendations. Empirical data were collected from travelers who visited a regional destination in the US and then analyzed with respect to its network stmcture. The results indicate that the tourist-activated network for the destination is rather sparse ...

<1 case/100,000 population/year, and the disease accounts for ≈2%–3% of all leukemias in adults in the United States (8). Infections are a common complication for patients with this disease (10). These 2 cases of imported melioidosis show that travelers with hematologic malignancies are at risk for such infections (1). Immunocompromised travelers might be first sentinels for ongoing endemic dis...
