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]
Mild cases of dengue fever can easily be confused with several common diseases including Influenza, measles, chikungunya, and zika. [61] [62] Dengue, chikungunya and zika share the same mode of transmission (Aedes mosquitoes) and are often endemic in the same regions, so that it is possible to be infected simultaneously by more than one disease ...
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.
For perspective, there have been 2,559 cases of dengue fever reported in U.S. states and territories since the start of 2024, per the CDC. A large majority of those (1,724) were reported in Puerto ...
Dengue is a viral fever spread through mosquito bites. It’s common in many tropical regions across the globe, but has recently appeared in more temperate climates. Dengue fever, once confined to ...
Most dengue fever patients recover in a week, but in severe cases the disease can be life-threatening and require hospitalization since it can result in shock, internal bleeding and even death.
Severe dengue is defined as that associated with severe bleeding, severe organ dysfunction, or severe plasma leakage while all other cases are uncomplicated. [40] The 1997 classification divided dengue into undifferentiated fever, dengue fever, and dengue hemorrhagic fever. [5] [46] Dengue hemorrhagic fever was subdivided further into grades I ...
[47] This live-attenuated vaccine, developed by Takeda is similar to the Dengvaxia vaccine in the fact that it contains a weakened version of the four variants of dengue virus. The difference between the two vaccines is the TAK-003 vaccine can be administered without a prior dengue infection and it also induces cellular immunity against dengue ...
