Knowra Dengue fever Dengue fever Dengue fever is an illness caused by dengue viruses, usually transmitted through the bites of infected Aedes mosquitoes. It ranges from a febrile illness with severe aches and rash to severe disease involving plasma leakage, bleeding, or shock.
Dengue virus : A group of four related flaviviruses that cause dengue infection in humans. These viruses directly cause the illness and circulate between people and mosquitoes.
Dengue vaccine : A vaccine intended to reduce the risk of dengue disease or severe outcomes. Vaccination can prevent some cases, but recommendations depend on prior infection and local conditions.
Dengue fever symptoms : The signs and symptoms associated with dengue, including fever, headache, muscle pain, and rash. These common features define the illness in its typical, non-severe presentation.
Chikungunya : A mosquito-borne viral disease that commonly causes fever and severe joint pain. Its symptoms overlap with dengue, but persistent joint pain is especially characteristic.
Aedes aegypti : A mosquito species that spreads dengue and other arboviruses, especially in tropical and subtropical cities. It is the principal mosquito vector in many dengue-endemic regions.
Dengvaxia : A live attenuated dengue vaccine licensed for people with evidence of previous dengue infection in certain settings. Its restricted use reflects the risk of severe disease in some recipients without prior infection.
Warning signs of dengue : Clinical findings such as persistent vomiting, abdominal pain, and mucosal bleeding that may precede severe dengue. Recognizing these signs prompts closer monitoring as the fever subsides.
Zika fever : A usually mild illness caused by Zika virus and transmitted mainly by Aedes mosquitoes. Shared vectors and overlapping symptoms make it a frequent alternative diagnosis.
Aedes albopictus : A mosquito species native to Asia that transmits dengue and has spread to many temperate regions. This adaptable secondary vector can sustain transmission beyond the range of Aedes aegypti.
Dengue diagnosis : The clinical and laboratory process of identifying dengue infection and assessing its severity. Early confirmation helps distinguish dengue from similar febrile illnesses and guide monitoring.
