BACKGROUND Imported malaria is quite common in the United States. Increasing antimalarial drug resistance and changes in travel patterns may have important implications for the prevention, clinical presentation, and management of this disease. METHODS Medical records were reviewed for 121 patients with microscopically confirmed malaria diagnosed at 2 university-affiliated hospitals in San Fra...

The self as traveler experiences internal dynamics reflected in travel writings. This paper analyzes five French writings reveal self-construction of travelers who explored East 19th century. analysis results show travelers’ divided into Enlightenment or Romantic subjects tru...
We prove that a GF(q)-linear Rédei blocking set of size qt + qt−1 + · · · + q + 1 of PG(2, qt ) defines a derivable partial spread of PG(2t − 1, q). Using such a relationship, we are able to prove that there are at least two inequivalent Rédei minimal blocking sets of size qt + qt−1 + · · · + q + 1 in PG(2, qt ), if t ≥ 4.
Travel time reliability has generally been surmised to be an important attribute of transportation systems. In this paper, we study the contribution of travel time reliability in travelers’ route choice decisions. Traveler’s route choice is formulated as a mixed-logit model, with the coefficients in the model representing individual traveler’s preferences or tastes towards travel time, reliabil...

Constrained cognitive abilities cause imperfections in traveler’s choice behavior which are largely systematic and predictable. This paper introduces the concept ‘regulation flexibility’ to build upon this knowledge, taking it as an advantage to increase the effectiveness of traffic network management rather than a threat. It assumes that within set boundaries, traffic management measures are p...
There is a wide range in prevalence of hepatitis B virus (HBV) infection and HBV immunization programs between different regions. Hepatitis B is a vaccine preventable disease yet is still endemic in the majority of countries in Asia. Despite the decreasing global prevalence of chronic HBV infection, there is still considerable risk of HBV infection among international travelers to high endemic ...
BACKGROUND Dengue fever is the most common arboviral disease in travelers. In countries where dengue virus is endemic, sequential (secondary) infections with different dengue virus serotypes are associated with disease severity. Data on severity and secondary infection rates in a population of travelers are lacking. METHODS Intensified surveillance of dengue fever in travelers was performed w...
