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.
Dengue fever is caused by infection through viruses of the family Flaviviridae. The illness is most commonly transmitted by Aedes aegypti mosquitoes in tropical and subtropical regions. [58] Dengue virus has four different serotypes, each of which are antigenically related but have limited cross-immunity to reinfection. [59]
For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus. Although invertebrate-transmitted diseases pose a particular threat on the continents of Africa, Asia and South America, there is one way of controlling invertebrate-borne diseases, which is by controlling the invertebrate vector.
Dengue fever (UK: / ˈ d ɛ ŋ ɡ eɪ / or US: / ˈ d ɛ ŋ ɡ iː /), also known as breakbone fever, is an infectious tropical disease caused by the dengue virus. Symptoms include fever , headache , myalgias and arthralgias , and a characteristic skin rash that is similar to measles .
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. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]
Dengue vaccine is a vaccine used to prevent dengue fever in humans. [9] Development of dengue vaccines began in the 1920s but was hindered by the need to create immunity against all four dengue serotypes. [10] As of 2023, there are two commercially available vaccines, sold under the brand names Dengvaxia and Qdenga. [11] [12]
