Dengue virus. Dengue virus (DENV) is the cause of dengue fever. It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease.
Dengvaxia is a weakened but live vaccine and works by triggering an immune response against four types of dengue virus. As of 2016, the dengue vaccine had been approved for medical use in eleven countries and in 2019, was approved for medical use in the United States.
Dengue appeared in the Hawaiian Islands in late 2015, with at least 190 cases confirmed by year end. Most cases were reported on the island of Hawaii (the "Big Island"). 2016. Argentina registered a Dengue fever outbreak in late January 2016 with 13 of 24 provinces affected.
The Dengue virus is spread by several species of female mosquitoes, of the Aedes type. The fact that mosquitoes are the vector for the virus means that the disease is much more common in warmer climates, and below an elevation of 1000m (or 3000 feet).

Zika virus is related to the dengue, yellow fever, Japanese encephalitis, and West Nile viruses. Since the 1950s, it has been known to occur within a narrow equatorial belt from Africa to Asia. From 2007 to 2016 [update] , the virus spread eastward, across the Pacific Ocean to the Americas, leading to the 2015–2016 Zika virus epidemic .
On February 1, 2016, the WHO declared the current Zika virus outbreak an international public health emergency, and the Brazilian President released a decree that increased local and federal pest control agents' access to private property required by mobilization actions for the prevention and elimination of Aedes mosquito outbreaks in the country.

Dengue viruses are spread to people through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito. Dengue is common in more than 100 countries around the world. Forty percent of the world’s population, about 3 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk.
