Arbovirus encephalitis is caused by a virus from the Arbovirus group.
The major causes of arbovirus encephalitis include the members of the viral families alphavirus (causing Eastern equine encephalitis, Western equine encephalitis, and Venezuelan equine encephalitis), flavivirus (responsible for St. Louis encephalitis, Japanese encephalitis, Tick-borne encephalitis, Murray Valley encephalitis, Russian spring-summer encephalitis, and Powassan), and bunyavirus (causing California encephalitis).
Prognosis depends on the particular type of arbovirus causing disease, and on the age and prior health status of the patient.

Arbovirus (short for arthropod-borne) infections are caused by any number of viruses transmitted by arthropods such as mosquitoes and ticks.These infections generally occur during warm weather months when mosquitoes and ticks are active.
Lyme disease and Rocky Mountain spotted fever are not caused by viruses and are not considered arbovirus infections.
Arbovirus encephalitis cannot be distinguished clinically from several other types of viruses that attack the central nervous system.

 Arbovirus Facts
The presence of an arbovirus in a particular area depends on the availability of specific types of mosquitoes that can carry it and specific birds or animals that can be infected.
Because people are not important in the life cycle of most arboviruses, arbovirus infections are generally rare in humans.
When people are part of the natural cycle and are necessary for transmitting infection, such as for dengue and urban yellow fever viruses, then infection in people is more common.

The NSW arbovirus surveillance program for monitoring mosquito populations has been conducted annually since the summer of 1984/85, with arbovirus isolations from the mosquitoes beginning in the 1988/89 season.
The trapping program is designed to cover the period of seasonal increase and decrease in the populations of the major arbovirus vectors, from mid-spring to mid-autumn, and also to cover the period for natural activity and transmission of arboviruses (especially the alphaviruses and the flaviviruses).
To identify arbovirus (both flavivirus and alphavirus) activity by processing mosquito samples, isolating arboviruses through cell culture and identifying isolated arboviruses with serological techniques.

 Encephalitis: Viral
In most of the relatively common US arbovirus infections, including St. Louis encephalitis and the West Nile virus, less than 1% of infections cause any noticeable symptoms.
The symptoms and severity of the condition depend on the age of the patient at time of the infection, the type of virus, and the part or parts of the brain affected.
Early symptoms of arbovirus encephalitis are similar to those of a flu and usually include fever, headache, nausea and vomiting, muscle aches, and lethargy.

The Arbovirus Surveillance Program at the Texas Department of State Health Services is designed to monitor mosquitoes to detect and track the circulation of encephalitis viruses in mosquitoes in the environment prior to the development of human disease due to these viruses.
This is a cooperative program including the Zoonosis Control, General Sanitation, and Infectious Disease Epidemiology and Surveillance Divisions of TDSHS as well as the Arboviral Disease Team of the laboratory.
The program serves as an early warning system to detect the presence of virus activity in mosquito populations before humans are infected.

Included in the arbovirus group are single-stranded, positive sense RNA viruses belonging to the Alphavirus and Flavivirus genera of the families Togaviridae and Flaviviridae respectively [2].
The serological diagnosis of arbovirus infections usually involves the testing of paired acute and convalescent sera in parallel, and requires stable, reliable antigens that are reproducible and provide consistent results.
Further investigations of the pH and osmolarity of antigen suspensions, which are known to affect the rate of BEI inactivation [9], may provide a possible explanation for the difference observed in inactivation rates.

In 1995 this vision became a reality when the internationally renowned Arbovirus Research Unit in the School of Public Health at UC Berkeley was transferred to UC Davis as a founding component of the Center for Vectorborne Diseases (CVEC).
Epidemiologically important changes in patterns of arbovirus transmission, the environment, and human demographics indicate that without well-designed programs for surveillance, prevention, and control the negative effects of arboviral disease threats in California will continue to grow.
The objective of the Davis Arboviurus Research Unit (DARU) is to foster collaboration among faculty, staff, and students in order to advance the detailed understanding of vector-borne viruses and their arthropod vectors and to use that knowledge to prevent disease within the state, nationally, and internationally.

 Arbovirus definition - Medical Dictionary definitions of popular medical terms
Arbovirus: A class of viruses transmitted to humans by arthropods such as mosquitoes and ticks.
The name arbovirus was coined in part by Dr. William C. Reeves (1916-2004) to connote the class of viruses carried by insects and responsible for diseases like malaria, dengue fever, encephalitis and West Nile.
The arboviruses were originally called 'arborviruses' but the spelling was changed, dropping the second 'r' because of the potential of mis-identification with trees.

The term 'prevalence' of Arbovirus usually refers to the estimated population of people who are managing Arbovirus at any given time.
The term 'incidence' of Arbovirus refers to the annual diagnosis rate, or the number of new cases of Arbovirus diagnosed each year.
Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
