Arboviral diseases have likely affected humans for centuries, with early records describing conditions now recognized as dengue and yellow fever. The pivotal discovery in the late 19th and early 20th centuries was identifying arthropods, particularly mosquitoes, as vectors for these viral agents, revolutionizing our understanding of their transmission and control.
Arboviral diseases are transmitted to humans and animals primarily through the bite of an infected *arthropod vector*, most commonly mosquitoes (e.g., *Aedes*, *Culex* species) and ticks. These vectors acquire the virus by feeding on an infected host (human or animal) and then transmit it when they bite another susceptible host.
