Which RNA viruses are most commonly spread by ticks, mites, and mosquitoes?

• A. Retroviruses
• B. Arboviruses
• C. Orthomyxoviruses
• D. Corynebacterium

Answer: (B)

Arboviruses, or arthropod-borne viruses, are named for their transmission via arthropods such as ticks, mites, and mosquitoes. These viruses require these vectors for their lifecycle, as the arthropods pick up the virus from infected hosts and subsequently transmit it to humans or animals. Common examples of arboviruses include West Nile virus, Zika virus, and dengue virus, all of which have significant roles in public health and animal disease. Retroviruses, on the other hand, are primarily transmitted through direct contact with infected bodily fluids and do not rely on arthropods for transmission. Orthomyxoviruses, such as the influenza viruses, are mostly spread through respiratory droplets and are not associated with arthropods. Corynebacterium refers to a genus of bacteria, rather than a virus, and is not transmitted via arthropods at all. Thus, the relationship of arboviruses with their arthropod vectors makes this answer the most accurate.
