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...

BACKGROUND Atovaquone-proguanil (AP) is the most commonly used treatment for uncomplicated Plasmodium falciparum malaria in the United States. Apparent AP treatment failures were reported 7 months apart in 2 American travelers who stayed in the same compound for foreign workers in Rivers State, Nigeria. METHODS We analyzed pretreatment (day 0) and day of failure samples from both travelers fo...

prevention of infectious diseases during travel but also with the personal safety of travelers and the avoidance of environmental risks. The major content areas of travel medicine include the global epidemiology of the health risks to the traveler, vaccinology, prevention of disease and pretravel counseling. Many of these risks can be minimized by precautions taken before, during and after trav...

Edy wrinkled her nose. “Why?” she asked. “It will be wonderful!” I exclaimed. “The people are different. The animals are different. Even the countryside is different. It will be a fantastic getaway. We’ll have a great time. Can you think of anyplace better to go?” “Martha’s Vineyard,” she answered. “Someplace nearby. I don’t want adventure. I just want to spend time with you.” Sensing my disapp...

TO THE EDITOR—I warmly thank Drs Bradley Connor and Jay Keystone for their meritorious editorial commentary [1] on our research showing that antibiotic use predisposes travelers to colonization with extended-spectrum beta-lactamaseproducing Enterobacteriaceae (ESBL-PE) [2]. They cogitate about fundamental problems associated with refraining from antibiotics for travelers’ diarrhea (TD), listing...

US health officials will begin to actively monitor all travelers arriving from the three west African countries affected by the Ebola epidemic, Liberia, Sierra Leone, and Guinea, the US Centers for Disease Control and Prevention announced 22 October. The monitoring will begin 27 October in six states that are the destinations of 70% of travelers from these countries, NewYork, Pennsylvania, Mary...

Travelers can introduce viruses from disease-endemic to non-disease-endemic areas. Serologic and virologic tests confirmed dengue virus infections in 3 travelers returning to Japan: 2 from Tanzania and 1 from Cote d'Ivoire. Phylogenetic analysis of the envelope gene showed that 2 genetically related virus isolates belonged to dengue virus type 3 genotype III.
