Mosquito-Borne Arboviruses

Mosquito-borne arboviruses are transmitted to humans through the bite of an infected mosquito, and infections typically occur during the summer months when insects are most active. In the United States, the most common mosquito-borne illness is West Nile virus (WNV), a neurotropic human pathogen capable of spreading to the brain via hematogenous dissemination. Other neurotropic mosquito-borne arboviruses, including St. Louis encephalitis (SLE) virus and Japanese encephalitis virus, are less common but may cause similar symptoms. 

Emerging arboviruses, including dengue, Zika, and chikungunya, have similar epidemiologies, transmission cycles, and clinical symptoms at onset (although complications vary substantially).  Laboratory testing options for mosquito-borne arboviruses include serology and nucleic acid testing (NAT). The appropriate methodology depends on the suspected infection and duration of symptoms.
