What is a probable case of dengue fever?
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. Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, all of which can cause the full spectrum of disease.
Causes. Dengue is a Flaviviridae virus, with five genetic types. [8] [9] Here is the virus drawn as a 3-dimensional model of the envelope protein. [10] Dengue is in the same family as other well known viruses carried by mosquitoes that cause tropical diseases, such as yellow fever, West Nile, and Zika virus. [11]
Jan 22, 2014 · In this paper, we report the historical significance of dengue outbreaks in the USA between 1780 and 1945, along with the elimination strategies of the vector mosquito, Aedes aegypti. We then detail the re-emergence of dengue into the USA between 1999 and today and discuss future strategies for detection and control.

Fever, headache, muscle and joint pain, rash. Can be severe, mild or asymptomatic [1] [2] Dengue fever is a mosquito-borne disease caused by dengue virus, prevalent in tropical and subtropical areas. It is frequently asymptomatic; if symptoms appear they typically begin 3 to 14 days after infection.
Mar 28, 2022 · Abstract. Dengue is an arboviral disease caused by dengue virus (DENV), leading to approximately 25,000 deaths/year and with over 40% of the world’s population at risk. Increased international travel and trade, poorly regulated urban expansion, and warming global temperatures have expanded the geographic range and incidence of the virus in ...

Print. What Is Dengue Fever? Dengue (DEN-gee) fever is a tropical disease caused by a virus carried by mosquitoes. The virus can cause fever, headaches, rashes, and pain throughout the body. Most cases of dengue fever are mild and go away on their own after about a week.
Introduction. Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. Like other viruses, the dengue virus is a...
