We sought to compare four screening interventions for travelers from low-incidence countries, who visit countries with varying tuberculosis incidence. METHODS Decision analysis model: We considered hypothetical cohorts of 1,000 travelers, 21 years old, visiting Mexico, the Dominican Republi...
Typhoid vaccination is recommended in the United States before travel to countries where typhoid fever is endemic, though little information is available on its effectiveness in travelers. We estimated typhoid vaccination effectiveness (VE) by comparing vaccination status in cases of typhoid fever and paratyphoid fever (Salmonella Paratyphi A infection, against which typhoid vaccine offers no p...
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...

Measuring Illegal Immigration at US Border Stations by Sampling from a Flow of 500 Million Travelers
Five hundred million travelers enter the US yearly at a Port of Entry (POE) after an Immigration & Naturalization Service (INS) interview. We describe a general method for sampling from a flow, and summarize results from random reinspections of travelers at 20 POEs. Analyses reveal that 47 in 5614 travelers (0.8% ± 0.24%) were erroneously granted entry. Results suggest INS intercepts 9.3% to 16...

This paper exploits an unusual transportation setting to generate some of the first revealed preference value of a statistical life (VSL) estimates from a low-income setting. We estimate the trade-offs individuals are willing to make between mortality risk and cost as they travel to and from the international airport in Sierra Leone. The setting and original dataset allow us to address some typ...
