Why Arbo viruses are named so?
arbovirus, acronym derived from arthropod-borne virus, any of a group of RNA viruses that develop in arthropods (chiefly blood-sucking mosquitoes and ticks), in which they cause no apparent harm, and are subsequently transmitted by bites to vertebrate hosts, in which they establish infections and complete their growth …
Are arboviruses genetically related?
By the 1960s, the efforts had proven to be successful and these diseases that had been considered a public health problem were no longer causing devastation on a grand scale [2]. However, the past several decades have seen the re-emergence of arboviruses in areas outside of Africa.
What diseases do arboviruses cause?
These infections usually occur during warm weather months, when mosquitoes and ticks are active. Examples include California encephalitis, Chikungunya, dengue, Eastern equine encephalitis, Powassan, St. Louis encephalitis, West Nile, Yellow Fever, and Zika.
Is Zika a arbovirus?
The Centers for Disease Control and Prevention (CDC) note that more than 130 types of arbovirus can cause disease in humans. Two arboviruses that have recently spread throughout South America are Zika and chikungunya.
Can arboviruses be cured?
Because this is a viral disease, antibiotics will not help. There are no effective antiviral medicines at this time. There is no specific treatment for encephalitis. The main goal is to ease symptoms and keep the person’s breathing and circulation working well while the infection runs its course.
What does Arbo in arboviruses mean?
Arbovirus: A class of viruses transmitted to humans by arthropods such as mosquitoes and ticks. The first two letters of the words arthropod’ and borne, make up the ‘arbo’ that now designates this group of viruses as arthropod-borne.
How are arboviruses transmitted?
Arboviral disease is a general term used to describe infections caused by a group of viruses spread to people by the bite of infected arthropods (insects) such as mosquitoes and ticks. These infections usually occur during warm weather months, when mosquitoes and ticks are active.
Is Ebola an arbovirus?
The ACAV 1985 catalogue listing includes 12 arenaviruses, four hantaviruses, and Ebola and Marburg, which are not arboviruses but appear in the catalogue because they are viruses likely to be encountered by arbovirus field investigators.
What virus family is dengue?
Flaviviridae
Dengue virus/Family
What are encephalitis causing arboviruses?
In the U.S., arboviral encephalitis is usually caused by viruses transmitted by mosquitoes. There are four main causes of arboviral encephalitis in the U.S. These include eastern equine encephalitis, western equine encephalitis, St. Louis encephalitis, and LaCrosse encephalitis.
