Background information on Dengue Fever
Dengue is a mosquito-borne virus, whose main vectors for transmission are the Aedes aegypti (A. aegypti) mosquito and the Aedes Albopictus (A. albopictus) mosquito which serves as the second vector. Dengue is primarily carried by an infected female mosquito and transmitted to humans. A. aegypti mosquitoes live and breed in areas where water holding containers exist (Murray, Quam, & Wilder-Smith, 2013). Infected humans are the main carriers of dengue and can transport the virus to uninfected mosquitoes. In the 1950s, a severe cause of Dengue was discovered in Thailand and the Philippines; these severe cases became known as Dengue Fever (“WHO | Dengue and severe dengue,” n.d.).
The Dengue virus has four distinct serotypes, DENV-1, DENV-2, DENV-3 and DENV-4. All four serotypes originate from the family Flaviviridae and the genus Flavivvirus, and have been found to be responsible for severe dengue epidemics (Guzman et al., 2010). Infection of any four of viruses have shown to result in a person having lifelong immunity to that specific serotype (Murray et al., 2013). When Dengue fever is contracted a person will experience flu like symptoms such as headaches, nausea, vomiting and swollen glands. The incubation period in humans is 4-10 days after the infected mosquito bite with symptoms lasting 2-7 days. There is no immunization in place for Dengue fever and it there is no specific treatment. Infected persons are encouraged to seek medical care by a physician or nurse and maintain hydration.
