The World Health Organization's International Classification of Diseases divides dengue fever into two classes: uncomplicated and severe. [18] Severe dengue is defined as that associated with severe bleeding, severe organ dysfunction, or severe plasma leakage. [59] Severe dengue can develop suddenly, sometimes after a few days as the 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. [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]
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.
Enthusiasm regarding DDT became obvious through the American government's advertising campaigns of posters depicting Americans fighting the Axis powers and insects and through media publications celebrating its military uses. [37] In the South Pacific, it was sprayed aerially for malaria and dengue fever control with spectacular effects. While ...
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]
Mosquito control manages the population of mosquitoes to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria and the Zika virus .
Dengue fever, Japanese encephalitis, other hemorrhagic fevers: Regional arbovirus infections: California serogroup virus, Eastern equine encephalitis virus, Powassan virus, St. Louis encephalitis virus, Western equine encephalitis virus: Varicella voster infection- chickenpox, shingles, and unspecified Chickenpox: Chickenpox (regional)
In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in hemorrhage, thrombocytopenia and blood plasma leakage, or into dengue shock syndrome, where shock occurs. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti.
