Overview of West Nile Virus and Sandfly-borne Phlebovirus Infections in Anatolia

Abstract

Arthropod-borne (arbo) viruses are trafinsmitted to the susceptible hosts by blood-feeding arthropods such as mosquitoes, sandflies and ticks. Arboviral infections have had a significant global public health impact during the last decades due to their resurgence and dynamic epidemiologic features. In Turkey, cases and outbreaks due to previously underestimated arboviral infections have emerged since 2009. In this manuscript, previous and current data on two of the major arboviral infections, West Nile virus and Sandfly-borne Phleboviruses have been overviewed with a special emphasis on clinical presentation and laboratory evaluation.

Overview of West Nile Virus and Sandfly-borne Phlebovirus Infections in Anatolia

Öz

Artropod kaynaklı (arbo) viruslar, duyarlı konaklara sivrisinek, kum sineği ve kene gibi artropodların kan emmesi yoluyla bulaşır. Son yıllarda yeniden ortaya çıkan ve epidemiyolojik özelliklerinde değişiklikler izlenen çeşitli arboviral enfeksiyonlar, tüm dünyada önemli halk sağlığı sorunları oluşturmaktadır. Türkiye’de 2009 yılından günümüze, daha önce dikkat çekmemiş bazı arboviruslara bağlı olgular ve salgınlar ortaya çıkmıştır. Bu derlemede, iki önemli arbovirus olan Batı Nil virusu ve kum sineği (tatarcık) kaynaklı fleboviruslarla ilgili ülkemize ait veriler, klinik ve laboratuvar bulguları özellikle vurgulanarak ele alınmaktadır
