However, there is uncertainty in the travel medicine community regarding the evidence base for both estimates of risk for latent TB infection (LTBI) in long-term travelers and for information regarding which travelers may benefit from pre- or post-travel TB screening. Th...

A small proportion of air travelers make disproportionately more journeys than the rest of travelers. They also tend to interact predominantly with other frequent travelers in hotels and airport lounges. This group has the potential to accelerate global spread of infectious respiratory diseases. Using an epidemiologic model, we simulated exportation of cases from severe acute respiratory syndro...

Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive s...

Countries such as Sweden that have a low prevalence of methicillin-resistant Staphylococcus aureus (MRSA) offer the opportunity to discern and study transmission of imported cases of MRSA. We analyzed 444 imported cases of MRSA acquisition reported in Sweden during 2000-2003. Risk for MRSA in returning travelers ranged from 0.1 (95% confidence interval [CI] 0.01-0.4) per 1 million travelers to ...

Dengue cases showed region-specific peaks for Southeast Asia (June, September), South Central Asia (October), South America (March), and the Caribbean (August, October). Travel-related dengue exhibited annual oscillations with several epidemics ...

We propose a new service model that incorporates input from locals to provide instant travel assistance. No matter how well travelers plan, circumstances at their destination invariably force them to modify their plans, especially towards the end of a tour. However, it is difficult for travelers to get useful information or support. Accordingly, we propose a service model whereby on-site travel...
