Answer:
Infectious diseases are spread by either bacterial or viral agents and are ever-present in society. Usually infected cases are present in numbers below an expected threshold but every once in a while there may be an outbreak, a new strain or a new disease that has a significant impact at either a local or global level[1].

Dengue first appeared in the Americas and the Caribbean and with the assistance of the Pan American Health Organisation (PAHO) in the 1950s and 1960s the Americas were largely able to eradicate the presence of the Aedes Aegypti virtually eliminating the occurrence of Dengue[2].
