Rationale for review: Dengue is a frequent cause of febrile illness among travellers and has overtaken malaria as the leading cause of febrile illness for those traveling to Southeast Asia. The purpose is to review the risk of dengue and severe dengue in travellers with a particular focus on the...

Background: Influenza viruses are among the major causes of serious human respiratory tract infection worldwide. In line with the high disease burden attributable to influenza, these viruses play an important, but often neglected, role in travel medicine. Guidelines and recommendations regarding...

Longitudinal data examining travel-associated illness patterns are lacking. To address this need and determine trends and clusters in travel-related illness, we examined data for 2000-2010, prospectively collected for 42,223 ill travelers by 18 GeoSentinel sites. The most common destinations from...

Purpose of Review: Dengue is found in tropics and subtropics that are considered to be popular travel destinations. We set out to review the burden of dengue on international travelers. Recent Findings: GeoSentinel, a global network of travel medicine providers, has seen an increasing trend of ...

Zika and Ebola viruses can persist in semen and pose a risk for sexual transmission. To determine if dengue virus, another flavivirus, is similarly detectable in semen, we performed dengue PCR on semen in five patients with acute dengue virus infection. All five tested negative, suggesting that ...

Aedes aegypti, historically known as yellow fever (YF) mosquito, transmits a great number of other viruses such as Dengue, West Nile, Chikungunya, Zika, Mayaro and perhaps Oropouche, among others. Well established in Africa and Asia, Aedes mosquitoes are now increasingly invading large parts of the ...

Purpose of Review: This decade has seen a resurgence of yellow fever (YF) that has also affected travelers with a record number of international travelers infected by YF virus including the first documented importation of YF into Asia. Recent Findings: The recent resurgence of YF has been...

Purpose of review: The first dengue vaccine (Dengvaxia) was endorsed by the European Medicine Agency and the US Food and Drug Administration. Given the excess risk of severe dengue in seronegative vaccinees, use is restricted to seropositive individuals. Dengvaxia confers high protection against...

Background: Southern Europe is increasingly at risk for dengue emergence, given the seasonal presence of relevant mosquito vectors and suitable climatic conditions. For example, Aedes mosquitoes, the main vector for both dengue and chikungunya, are abundant in Italy, and Italy experienced the first ...
