Arboviral Diseases
Arboviral diseases are a group of viral illnesses that are primarily transmitted to humans through the bites of infected mosquitoes, ticks, and other arthropods (Arbovirus = Arthropod-borne virus). Less commonly, some arboviruses can be transmitted to humans through rare modes of transmission, such as blood transfusions, lab exposures, organ transplants, or perinatal transmission.
Arboviral diseases can be divided into two main categories: endemic and imported. Endemic arboviral diseases are infections which occur in Louisiana, such as Eastern Equine Encephalitis, St. Louis Encephalitis, and West Nile Virus. West Nile Virus is the most common arboviral disease in the state and has been actively transmitted since it was first detected in 2002. One case of Jamestown Canyon Virus (a virus more commonly found in the upper Midwest) was reported in Louisiana in 2017. Imported arboviral disease cases are instances where individuals test positive for an infection after traveling to another country. These diseases are not typically transmitted within Louisiana and are not circulating in local mosquito populations. The imported arboviral diseases most commonly identified in Louisiana are chikungunya and dengue.
