Dengue virus (DENV) is a positive-sense, single-stranded RNA virus that is transmitted by Aedes aegypti and Aedes albopictus mosquitoes. Greater than 100 million cases of dengue fever occur annually and over 2 billion people live in areas at risk for dengue transmission. There are four phylogenetically and serologically distinct DENV, which are capable of human-to-mosquito-to-human transmission...

Crimean-Congo hemorrhagic fever virus (CCHFV) belongs to the genus Nairovirus within the family Bunyaviridae and is the causative agent of severe hemorrhagic fever. Despite increasing knowledge about hemorrhagic fever viruses, the factors determining their pathogenicity are still poorly understood. The interferon-induced MxA protein has been shown to have an inhibitory effect on several members...

The principal aim of this work was to report the reintroduction of dengue virus serotype 3 in the Americas after an absence of 17 years. In addition, it describes the most common symptoms associated with classical dengue and hemorrhagic dengue and presents data on the distribution of the epidemic in the various comprehensive local health care systems of Nicaragua. The study group consisted of 3...

Arboviruses have evolved a number of strategies to survive environmental challenges. This review examines the factors that may determine arbovirus emergence, provides examples of arboviruses that have emerged into new habitats, reviews the arbovirus situation in western Europe in detail, discusses potential arthropod vectors, and attempts to predict the risk for arbovirus emergence in the Unite...

Dengue Hemorrhagic Fever (DHF) is a disease caused by the virus which transmitted through bite of Aedes Aegypti mosquito and enters human bloodstream. One triggers for transmission DHF at this time lack knowledge actions person in preventing eradicating nests. The purpose study was to determine relationship between public about 3m plus incidence (DHF). design used an analytical survey with cros...

Vector repellent is one element in the prevention of vector-borne diseases. Families that neglect protecting their children against vectors risk their children contracting illnesses such as West Nile virus, eastern equine encephalitis, Lyme disease, malaria, dengue hemorrhagic fever, yellow fever, babesiosis, Crimean-Congo hemorrhagic fever, Rocky Mountain spotted fever, Southern tick-associate...

Two large outbreaks of Ebola hemorrhagic fever occurred in Uganda in 2000 and 2007. In May 2011, we identified a single case of Sudan Ebola virus disease in Luwero District. The establishment of a permanent in-country laboratory and cooperation between international public health entities facilitated rapid outbreak response and control activities.

S TO MEETINGS (2007 only) Altamura, L.A., Schmaljohn, C.S., and Doms, R.W. (2007) Crimean-Congo hemorrhagic fever virus encodes an NSM protein. American Society for Virology 26th Annual Meeting. July 14-18 Corvallis, OR. Oral presentation.

We report the epidemiologic characteristics of Crimean-Congo hemorrhagic fever in Bulgaria, as well as the first genetic characterization of the virus strains circulating in the country in 2002 to 2003 that caused disease in humans.

Hantaviruses are endemic in the Balkan Peninsula. An outbreak of hemorrhagic fever with renal syndrome occurred in 2002 in Serbia and Montenegro. The epidemiologic characteristics and genetic relatedness of Dobrava/Belgrade virus strains responsible for most cases are described.
