The incidence of asymptomatic travel-related parasitic infection is uncertain. Previous studies did not distinguish new incident infections, from past infections. Regardless of symptoms, we performed multiplex real-time polymerase chain reaction on pre- and post-travel stool samples of Dutch long-term travelers to the (sub)tropics. Serological screening for Schistosoma spp. was only performed i...

Few data regarding the use of Japanese encephalitis (JE) vaccine in clinical practice are available. We identified 711 travelers at higher risk and 7,578 travelers at lower risk for JE who were seen at US Global TravEpiNet sites from September of 2009 to August of 2012. Higher-risk travelers were younger than lower-risk travelers (median age = 29 years versus 40 years, P < 0.001). Over 70% of h...

The Ebola virus disease (Ebola) epidemic in West Africa has so far produced approximately 25,000 cases, more than 40 times the number in any previously documented Ebola outbreak. Because of the risk for imported disease from infected travelers, in October 2014 CDC recommended that all travelers to the United States from Ebola-affected countries receive enhanced entry screening and postarrival a...

BACKGROUND Upper respiratory tract problems, eg, acute sinusitis are frequently occurring illnesses in returned travelers. The most accurate and cost-effective method for diagnosing these upper respiratory tract illnesses in hospital-based settings remains an area of uncertainty. In the present retrospective cohort study, the usefulness of routine sinus radiography in the diagnostic work-up of ...

BACKGROUND Pretravel health consultations help international travelers manage travel-related illness risks through education, vaccination, and medication. This study evaluated costs and benefits of that portion of the health consultation associated with malaria prevention provided to US travelers bound for West Africa. METHODS The estimated change in disease risk and associated costs and bene...

This paper presents a task model and task ontology based on travelers’ tasks, and an intelligent tourist information service system using them. With the recent advances in Internet and mobile technologies, there has been an increase in the use of intelligent tourist information services via the Web and mobile systems. In addition, many ontologies have been introduced in tourist domain to provid...

With the generalization of real-time traveler information, the behavior of modern transport networks becomes harder to analyze and to predict. It is now critical to develop simulation tools for mobility policies makers, taking into account this new information environment. Information is now individualized, and the interaction of a huge population of individually guided travelers have to be tak...

TRAVELER ARRIVALS WORLDwide exceeded 800 million in 2005. Today’s mobile populations and global economies lead to extended stays for many travelers. For long-term travelers visiting malaria-endemic countries, recommendations for prevention have been difficult to standardize due to the diversity of long-term travelers and their itineraries, the variation in quality of and access to medical care,...

In a stochastic roadway congestion and pricing model, one scheme (omniscient pricing) relies on the full knowledge of each individual journey cost and of early and late penalties of the traveler. A second scheme (observable pricing) is based on observed queuing delays only. Travelers are characterized by late-acceptance levels. The effects of various late-acceptance levels on congestion pattern...
