Diseases & Conditions
Infections caused by any of a number of viruses transmitted by arthropods such as mosquitoes and ticks, such as WEST NILE VIRUS, ENCEPHALITIS, eastern equine encephalomyelitis, St. Louis encephalitis, and California encephalitis. The term arboviral is short for arthropod-borne. These types of infections usually occur during warm weather months when mosquitoes are active.
Children are especially susceptible to getting an arboviral infection. Most of these type of infections are spread by infected mosquitoes, but only a few types of mosquitoes are capable of transmitting dis-ease—and only a few of these actually carry a virus. Infection with one arbovirus can provide immunity to that speciﬁc virus and may also protect against other related viruses.
Symptoms of the different types of arboviruses are usually similar, although they differ in severity. Most infections do not cause any symptoms at all; mild cases may involve a slight fever or headache. Severe infections quickly cause a severe headache, high fever, disorientation, coma, tremor, convulsions, paralysis, or death. Symptoms usually occur between ﬁve and 15 days after exposure.
Because there are no speciﬁc treatments for these kinds of viral infections, treatment is typically aimed at relieving symptoms.
The arboviral diseases can be prevented by using insect repellents when outdoors in mosquitoinfested areas, using screening, and community control programs.
