Zika virus: a new arboviral public health problem.

Abstract

Zika virus (ZIKV) is a single-stranded RNA virus in the Flaviviridae family and transmitted to human through infected mosquitos (Aedes aegypti and Aedes albopictus). Virus is closely related with other flaviviruses; dengue virus, yellow fever virus, West Nile virus, and Japanese encephalitis virus phylogenetically. Due to the possible relationship between virus and clinical features including microcephaly, ventricule, and eye deformities, Guillain-Barre syndrome increases the interest on this virus gradually. Along with the vector-borne transmission, exposure via blood transfusion and sexual contact are further concerns. Since December 2015, CDC reported 440.000-1.300.000 possible cases in Brazil and as of 19 January 2016, El Salvador, Venezuela, Colombia, Brazil, Surinam, French Guana, Honduras, Mexico, and Panama are the countries with active epidemic. CDC recommends ZIKV screening for all pregnants including asymptomatic cases those living in the active epidemic areas. Recently, virus is detected in the USA and most European countries including UK, Netherlands, Denmark, Switzerland, and Italy as a travel-associated infection. Owing to the changing world with increased capabilities for transportation globally, this vector-borne infection represents a valuable marker for the ability of spreading of any infection from its original area that it was first seen. In this review, we summarized the up-to-date data and reports in terms of the importance of the ZIKV infection in the public health.
