Dengue and chikungunya infections in travelers
Autor(es): Chen Lin H, Wilson Mary E
Resumo: Dengue - chikungunya are arboviruses that have caused major outbreaks - infected travelers, - both can be associated with fever - rash. We review the recent epidemiology of dengue - chikungunya infections - discuss their clinical presentations, diagnosis, treatment, - prevention. We highlight the findings in travelers. Globally dengue is one of the most common infections associated with travel, - incidence has increased in the Americas in recent years, especially in Brazil. Chikungunya has caused dramatic outbreaks in the Indian Ocean isl-s since 2004, - has spread to south - south-east Asia. Dengue virus - chikungunya virus also possess the potential to cause autochthonous transmission in temperate regions of developed countries due to the presence of the vector mosquito, Aedes albopictus. Such an outbreak (chikungunya infection) did occur in 2007 in Italy. A mutation in chikungunya virus (A226V) appears to improve virus survival in Aedes albopictus - also increase its virulence. The findings assist in differentiating dengue - chikungunya from other acute febrile illnesses - from each other. The findings also illustrate potential outbreaks in nonendemic countries, important toward developing control - prevention strategies.
